US 7324469

I'll verify the key facts against live sources before summarizing.

Let me check for any 2026 Federal Circuit activity and the current reexamination/PTO status.

One more check on the claim-construction outcome and reexamination activity.

US 7,324,469 B2 — "Satellite Distributed High Speed Internet Access"

Verification note: I could not query USPTO systems (PatentCenter/PTAB) or the Federal Circuit docket directly — I have no live USPTO/CAFC access here. The following is grounded in search results I retrieved plus the authoritative full text supplied. Items I could not confirm are flagged explicitly.

Bibliographic data

Ownership chain: Wilson → System Services, Inc. (2005) → Distalma Management LLC (2008) → Callahan Cellular L.L.C. (merger, 2015) → Intellectual Ventures II LLC (2024).

Abstract (verbatim)

A satellite distributed high-speed Internet "Hotspot" enables wireless and hardwired, satellite distributed Internet access for anyone with a PC or other web-ready device (wireless ready or cabled) and a valid credit card or prepaid coupon. The Hotspots can be located anywhere there is 120 volt electricity available or access to the sun for a solar panel and enough space to house the transceiver and mount a satellite dish. Upon connecting to the Hotspot, the user is directed to a remote server for log-on and validation of the user's account. During validation, the remote server verifies that prepaid access time remains in the user's account. Upon validation, the user may browse the web until the prepaid access time runs out. Alternatively, an account may be set up on a "continue until canceled" basis, wherein the user's credit card will be charged for the amount of time used during each session.

Plain-language overview of the independent claims

Claim 1 — Method of establishing and operating an Internet Hotspot (system-build + captive-portal method).
You set up a satellite dish that talks to the Internet through a satellite, a router connected to the dish, and a subscriber access unit sitting between the dish and the router. You install that gear in a rural place that sees a relatively high volume of transient traffic (spec examples: rest areas, restaurants, truck stops, rural hotels, conference centers, motels, state park lodges). A user connects a web-ready device to the router; the user creates a subscription account on a remote server; the user's browser is navigated to a subscriber access website; that website verifies the account is valid; and only then is Internet access allowed. In short: satellite-backhauled rural hotspot + remote-server subscription account + web-based validation gate. (This is the claim the PTAB and the district court focused on.)

Claim 15 — Method of providing satellite-distributed high-speed Internet access (protocol/session flow).
This is the more granular, step-by-step network-flow claim: provide a router (cable and/or wireless); assign the connected device a dynamic IP address (DHCP); router forwards the connection to the subscriber access unit; the unit retrieves a pre-stored static IP address of a remote server from memory; forwards the connection to the satellite dish; the dish communicates with a satellite that carries data over the Internet; a connection is established over the Internet with the remote server, whose interface appears to the user as a webpage; the server prompts for username/password; the server checks a database; if invalid or zero time remaining, the user is prompted to create a new account; the user is allowed to browse other sites until time runs out or logoff; and on logoff the server updates the database to subtract minutes used. (Note: unlike claim 1, claim 15 as issued does not itself recite the rural/transient-traffic installation — that limitation appears only in dependent claim 23.)

Claim 24 — Internet Hotspot apparatus.
An apparatus claim covering the physical installation: a satellite dish linked to the Internet via satellite; at least one router coupled to the dish; a subscriber access unit between the dish and the router that is capable of authenticating a subscription account associated with a user before allowing Internet access; and a web-ready device with a browser application coupled to the router. The dish, router and subscriber access unit must be located at a remote location experiencing a relatively high volume of transient traffic; the user authenticates and gets access by establishing a data connection between the device and the router.

Dependent claims add: wired jacks (2), prepaid-coupon account creation (3, 17), credit-card purchase of access time (4, 18), definite-quantity vs. "continued until canceled" billing (5–6, 19–20), existing/reciprocal merchant service billing (7–8, 21–22), subscriber-merchant-service verification (9), wireless connection incl. 802.11a/b/g/n (10, 14, 25, 28, 32), simultaneous multi-user access (11, 26–28), wireless transceiver extender units (12, 31), amplifier + antenna (13, 29), SSL webpage interface (16), rural high-transient-traffic installation (23), and a Vivato outdoor switch as the router (30).

Enforcement / PTAB / court activity identified

PTAB — IPR2025-00782 (the flagship challenge)

• Petitioners: American Airlines, Inc. and Southwest Airlines Co.; Patent Owner: Intellectual Ventures II LLC; filed April 30, 2025.
• A Director discretionary decision to refer the petition to a panel was issued September 19, 2025.
• Institution DENIED on November 18, 2025. Per the decision excerpt I retrieved, the Board found the Petitioner had not shown adequately that Bruner, or Wu, or their combination discloses or suggests "transient" traffic — the expert's opinion addressed "internet traffic," not "transient traffic," and was conclusory. Petitioner then filed a request for refund of post-institution fees (Nov. 28, 2025; refund approved Dec. 5, 2025).
• Google Patents labels the proceeding "Not Instituted - Merits."

District court litigation involving the '469 patent (per the Petitioner's Ex. 1016 "List of Cases for '469 Patent," plus Google Patents' litigation links):

• Intellectual Ventures I LLC v. Southwest Airlines Co., 7:24-cv-00277 (W.D. Tex.), filed Nov. 2, 2024 (Judge Albright docket).
• Intellectual Ventures I LLC v. American Airlines, Inc., 4:24-cv-00980 (E.D. Tex.), filed Nov. 2, 2024 (Judge Mazzant).
• Viasat, Inc. v. Intellectual Ventures I LLC, 1:25-cv-00056 (D. Del.), filed Jan. 14, 2025 (declaratory judgment).
• Anuvu Corp. v. Intellectual Ventures I LLC, 1:25-cv-00124 (D. Del.), filed Jan. 30, 2025.
• Google Patents also lists a Texas Northern District case, 3:26-cv-00782.
• Claim construction: In 4:24-cv-00980, Judge Mazzant held a hearing Jan. 22, 2026 and issued a Memorandum Opinion and Order on February 19, 2026 (Dkt. 127) construing disputed terms across the asserted patents, including two '469 terms: "a remote location experiencing a relatively high volume of transient traffic" (claim 24) and "a relatively high volume of transient traffic" (claim 24). American Airlines had proposed "a fixed remote location experiencing …" for the first term and indefiniteness as to "relatively high" and "transient" for the second; IV argued the specification's location examples supply objective boundaries. I do not have the constructions the Court actually adopted — the retrieved material shows the briefing and the hearing, not the dispositive holdings. Treat that as unverified.

Post-grant / reexamination

• Google Patents' legal-events table lists two "Request for reexamination filed" entries dated 2026-01-13 (effective date 2025-10-21) and 2026-01-20 (effective date 2025-10-29). I could not verify these, retrieve reexamination control numbers, or determine their status; the event/effective-date pairing on that page looks internally inconsistent, so I would not rely on it without checking USPTO reexam records.

Federal Circuit (2026)

• I found no 2026 (or other) CAFC appeal docket naming the '469 patent in my searches. That is a negative search result, not proof of absence — I cannot query the CAFC docket directly. The only Federal Circuit authority surfacing in this context was Niazi Licensing Corp. v. St. Jude Medical S.C., Inc., 30 F.4th 1339 (Fed. Cir. 2022), cited by IV in briefing on definiteness; that is a cited case, not an appeal of this patent. Note also that the IPR institution denial (Nov. 2025) is not appealable by the Petitioner in the ordinary course, and the E.D. Tex. case remains at the claim-construction stage, so a 2026 appeal of the '469 patent would be unusual at this point.

Points of uncertainty / caveats

1. Assignee: "Intellectual Ventures II LLC" is the recorded owner of the '469 patent. Some co-filed Delaware actions (e.g., 1:26-cv-00392, 1:26-cv-00397, 1:26-cv-00417 in 2026) name Intellectual Ventures I LLC and several related entities — I did not confirm whether the '469 patent is asserted in those specific later-filed cases.
2. Claim construction outcome for the two '469 terms is unverified (see above).
3. Reexamination filings and their status are unverified.
4. Expiration: Google Patents shows "Expired – Lifetime" with an adjusted expiration of 2026-04-13. Given the Sept. 27, 2004 filing date and 20-year term, plus terminal disclaimer/adjustment effects, this is plausible but is an assumption by the source, not a legal conclusion.
5. The two "Satellite distributed high speed internet access" patents in this family (US 7,324,469 and US 7,821,984) should not be conflated; the '469 is the parent and the '984 is the CIP child.

I'll research the litigation history for US Patent 7,324,469. Let me run multiple targeted searches.

I have good initial data. Let me dig into the remaining cases (Viasat, Anuvu), the reexaminations, and the case list exhibit.

Let me confirm the reexamination proceedings and current status of the American Airlines case.

I've reached the search limit for this session. Below is the litigation landscape for US Patent 7,324,469 ("the '469 Patent") as it can be established from the sources retrieved, including the patent record itself (Google Patents / USPTO assignment data), PACER-derived dockets (Justia, CourtListener/RECAP), and PTAB data (IPR2025-00782 docket, GreyB/IPVerse).

Patent identity (verified, no auto-correction)

• US 7,324,469 B2, "Satellite Distributed High Speed Internet Access," issued Jan. 29, 2008
• Inventor: W. David Wilson
• Application 10/950,860, filed Sep. 27, 2004; priority to provisionals 60/507,022 (Sep. 29, 2003), 60/517,044 (Nov. 4, 2003), 60/523,061 (Nov. 18, 2003)
• Ownership chain: Wilson → System Services, Inc. (2005) → Distalma Management LLC (2008) → Callahan Cellular L.L.C. (2015/2016 merger) → Intellectual Ventures II LLC (assignment executed/recorded Sep. 26, 2024, Reel/Frame 068714/0394)
• Asserted claim in the litigation: claim 24 (the "Internet Hotspot" system claim). Legal status shown as Expired – Lifetime, adjusted expiration 2026-04-13

A continuation-in-part (US 11/155,292 → US 7,821,984) also exists but is a different patent and is not part of the question; I have not returned it as a '469 matter.

Known litigation / contested proceedings involving the '469 Patent

Case-by-case detail

1. Intellectual Ventures I LLC v. American Airlines, Inc. — E.D. Tex. 4:24-cv-00980-ALM

• Plaintiffs: Intellectual Ventures I LLC and Intellectual Ventures II LLC. Defendant: American Airlines, Inc.
• Filed: Nov. 2, 2024 (jury trial demanded). Six patents-in-suit, including the '469 Patent.
• American filed a partial motion to dismiss Jan. 27, 2025 (after stipulated extensions).
• American moved to sever and stay the Viasat-related claims (customer-suit exception); the motion was DENIED — Intellectual Ventures I LLC v. Am. Airlines, Inc., No. 4:24-cv-980, 2025 WL 2161425 (E.D. Tex. July 30, 2025). The court found American was not a "mere reseller/end user" because claim 24's web-ready-device/authentication functionality implicated American's own passenger portal.
• Claim construction: Joint Claim Construction Statement filed Aug. 4, 2025 (Dkt. 67). Disputed '469 terms: "a remote location" and "a relatively high volume of transient traffic" (both claim 24). Expert testimony (Michael Goodrich) taken Aug. 8, 2025 on "fixed remote location."
• Status: Pending; no Markman/trial date set in the records retrieved. (Note: the parties also disputed whether additional patents, e.g., '282, '841, '584, appeared in the case.)

2. Intellectual Ventures I LLC v. Southwest Airlines Co. — W.D. Tex. 7:24-cv-00277-ADA → N.D. Tex. 3:25-cv-02885

• Filed: Nov. 2024, W.D. Tex. (Judge Alan Albright); same six patents as the American case.
• The case was transferred to the N.D. Tex., where it appears as 3:25-cv-02885.
• On Mar. 10, 2026, the court (Mag. J. David L. Horan) granted Southwest's motion to sever and stay the '469 and '326 claims under the customer-suit exception and the traditional stay factors, and administratively closed the severed action. The court found the Delaware declaratory-judgment actions (Viasat and Anuvu) would resolve the "major issues."
• Status: '469 claims stayed/administratively closed; joint status reports required every 60 days or within 14 days of disposition of the Delaware actions.

3. Intellectual Ventures I LLC v. Southwest Airlines Co. — N.D. Tex. 3:26-cv-00782 (severed action)

• The severed action created by the Mar. 10, 2026 order, containing Count III ('326) and Count IV ('469).
• Filed: Mar. 10, 2026. Judge: Sam A. Lindsay (with Mag. J. Horan).
• Status: Open but administratively closed (JS-6 submitted to remove from statistical records); "nothing in this order shall be considered a dismissal or disposition."

4. Viasat, Inc. v. Intellectual Ventures I LLC — D. Del. 1:25-cv-00056-CFC

• Plaintiff: Viasat, Inc. Defendants/counterclaim-plaintiffs: Intellectual Ventures I LLC and IV II LLC.
• Filed: Jan. 14, 2025 — declaratory judgment of non-infringement of the '469 and '326 Patents, prompted by IV's infringement suits against Viasat's airline customers.
• IV moved to dismiss/stay/transfer (Feb. 20, 2025); denied July 11, 2025 (D.I. 60). IV filed answer and counterclaims July 25, 2025.
• § 101 motion: Viasat moved for judgment on the pleadings that claim 24 (and other asserted claims) of the '469 Patent are patent-ineligible. IV's answering brief filed Feb. 3, 2026; Viasat's reply Feb. 17, 2026; Viasat requested oral argument. (Viasat characterizes the patent as claiming the abstract idea of "paying for a resource"; IV argues the specific satellite-hotspot network architecture with a "subscriber access unit" is an inventive concept.)
• Claim construction: Joint chart filed Jan. 15, 2026; on Mar. 13, 2026 the parties stipulated to withdraw all claim construction disputes (D.I. 103).
• Trial: set Nov. 15, 2027. Status: Pending.

5. Anuvu Corp. v. Intellectual Ventures I LLC — D. Del. 1:25-cv-00124-CFC

• Plaintiff: Anuvu Corp. Defendants: Intellectual Ventures I LLC and IV II LLC.
• Filed: Jan. 30, 2025 — declaratory judgment action concerning the IV patents (the complaint focuses primarily on the '326 Patent; Anuvu is the in-flight connectivity vendor accused via the Southwest suit).
• IV moved to dismiss on Mar. 18, 2025 (briefing followed). Claim construction was coordinated with the Viasat case; all disputes were withdrawn by stipulation Mar. 13, 2026.
• Status: Pending. (I could not confirm in the retrieved records the disposition of IV's motion to dismiss.)

6. IPR2025-00782 — American Airlines, Inc. & Southwest Airlines Co. v. Intellectual Ventures II LLC (PTAB)

• Filed: Apr. 30, 2025. Petitioners: American Airlines, Inc. and Southwest Airlines Co. Patent Owner: Intellectual Ventures II LLC. Patent: US 7,324,469 (claim 24 challenged).
• Petitioner experts/counsel: Declaration of C. Easttom; counsel McKool Smith (John B. Campbell et al.). Patent Owner counsel: Volpe Koenig (Brandon R. Theiss, lead).
• Prior-art exhibits included US 2002/0138625 (Bruner), US 6,445,777 (Clark), US 2003/0050041 (Wu), US 6,105,060 (Rothblatt), US 5,749,075 (Toader), EP 1 098 455 A2 (Berger).
• A "Director Discretionary Decision: Refer" issued Sept. 19, 2025 (referral under the Director's discretionary-denial procedures), after which the Board issued its Institution Decision: Deny on Nov. 18, 2025 — institution denied, terminating the proceeding. Petitioner's refund of post-institution fees was requested Nov. 28, 2025 and approved Dec. 5, 2025. The Google Patents record labels this proceeding "Not Instituted – Merits."
• Status: Terminated — institution denied.

7. Ex parte reexamination requests (USPTO)

• The '469 Patent record reflects two separate "Request for Reexamination filed" events: one recorded 2026-01-13 (effective date Oct. 21, 2025) and another recorded 2026-01-20 (effective date Oct. 29, 2025).
• Status: These appear to be pending as of the record date. I could not identify the requesters or their substantive grounds from the retrieved data — I am not certain of these details and flag them as unconfirmed. (Note the odd date pairing: the "effective" dates precede the recordation dates; I report them literally as shown rather than reconciling them.)

Consolidated "cases for the '469 Patent" list (from Petitioners' Exhibit 1016, filed Aug. 29, 2025 in IPR2025-00782)

The petitioners' own "List of Cases for '469 Patent" (from Docket Navigator) enumerated five matters then pending:

1. American Airlines, Inc. et al. v. Intellectual Ventures II LLC — IPR2025-00782 (PTAB), Apr. 30, 2025
2. Anuvu Corp. v. Intellectual Ventures I LLC et al — 1:25-cv-00124 (D. Del.), Jan. 30, 2025
3. Viasat, Inc. v. Intellectual Ventures I LLC et al — 1:25-cv-00056 (D. Del.), Jan. 14, 2025
4. Intellectual Ventures I LLC et al v. American Airlines, Inc. — 4:24-cv-00980 (E.D. Tex.), Nov. 2, 2024
5. Intellectual Ventures I LLC et al v. Southwest Airlines Co. — 7:24-cv-00277 (W.D. Tex.), Nov. 2024

Subsequent developments (after that exhibit) added the N.D. Tex. 3:25-cv-02885 transferred case, the severed 3:26-cv-00782 action, and the two reexamination requests.

Caveats and confidence notes

• Distinguish "litigation" from "PTAB/PTO proceedings." Only items 1–5 are district-court litigation; items 6–7 are administrative proceedings. The '469 Patent has no reported CAFC appeal in the records I retrieved.
• I did not find any plaintiff other than the Intellectual Ventures entities (or their predecessors) asserting the '469 Patent, and no earlier (pre-2024) enforcement litigation. As far as the retrieved docket data shows, the '469 Patent was first asserted in the Nov. 2024 IV airline suits.
• Unverified items: (a) the outcome of IV's motion to dismiss in the Anuvu case; (b) the identity/grounds of the reexamination requesters; (c) whether 3:25-cv-02885 is definitively the transferred 7:24-cv-00277 (I infer this from the severance order's reference to a prior transfer and trial date set before transfer). Treat these as lower-confidence.
• The IV entities are careful to distinguish Intellectual Ventures I LLC and Intellectual Ventures II LLC; the '469 Patent is owned by IV II LLC, and both entities appear as plaintiffs/counterclaim-plaintiffs in the district-court actions.

I'll verify the PTAB picture for US 7,324,469 against public sources, since the structured ODP block reports no AIA trials but the patent record itself shows a PTAB docket entry.

Key finding: the ODP block says no AIA trials, but the public record shows a real IPR. Let me dig into its details and check for any additional petitions or appeals.

Let me pin down the institution-denial reasoning, check for a parallel IPR, and look into the reexamination entries.

Sourcing note (read first)

The structured "PTAB proceedings on file" block for US 7,324,469 says the USPTO ODP API returns no AIA trial proceedings for this patent. That is contradicted by the public record. The Google Patents record for US7324469B2 itself carries a PTAB case entry ("PTAB case IPR2025-00782 filed — Not Instituted - Merits"), and web search surfaced the underlying petition, docket sheet, and institution decision. Per your instruction I am flagging it rather than defaulting to "no PTAB activity."

One caution on that Google Patents entry: the "Petitioner:" field on the patent page is attributed to Unified Patents PTAB Data, which is the data supplier, not the filer. The actual petitioner is American Airlines, Inc. and Southwest Airlines Co. There is no evidence Unified Patents (the defensive aggregator) filed anything here. Do not treat this as a Unified Patents IPR.

Proceedings overview

One AIA trial proceeding on file for the '469 — IPR2025-00782, institution denied on the merits (2025-11-18); zero claims invalidated, zero claims sustained on the merits (no FWD was ever reached), zero settlements, zero active proceedings. The defensive posture is therefore neither "hardened patent" nor "dead claims": the patent has never been adjudicated on validity at the PTAB, so all 32 claims — including the two independent method claims (1, 15) and the independent apparatus claim (24) — remain presumptively valid, but IPR2025-00782 tells you that a competent three-judge panel looked at a Bruner/Clark/Wu attack on claims 1–14 and 24–32 and found no reasonable likelihood of prevailing. Anyone contemplating an IPR on this patent starts from a merits denial, not a blank slate.

IPR2025-00782 — American Airlines, Inc. and Southwest Airlines Co. v. Intellectual Ventures II LLC

• Type: Inter Partes Review (35 U.S.C. §§ 311–319)
• Filed: 2025-04-30
• Status: "Institution Denied" / "Not Instituted - Merits" (verbatim from the PTAB records). Plain English: the Board refused to start trial, and it did so on the substance rather than on discretionary factors like Fintiv or § 325(d). Termination followed; post-institution fees were refunded (Petitioner's Request for Refund 2025-11-28; refund approved 2025-12-05).
• Judge panel: Administrative Patent Judges Ken B. Barrett, Georgianna W. Braden, and Stephen E. Belisle (per the 2025-11-18 decision caption). A Panel Change Order issued 2025-10-15, so the panel that decided was not necessarily the panel originally assigned.
• Counsels: Petitioner — John B. Campbell (lead), Alan Block, Casey Shomaker, Emily Tannenbaum, Kenneth M. Scott (McKool Smith P.C.), with Keith D. Harden, S. Wallace Dunwoody and Michael C. Wilson (Munck Wilson Mandala LLP). Patent Owner — Brandon R. Theiss (lead), Daniel H. Golub, Ryan W. O'Donnell, Dawn C. Kerner (Volpe Koenig), and Russell J. Rigby (IV, Chief Counsel, Litigation).
• Petition grounds: Challenged claims 1–14 and 24–32 (all claims except 15–23). Identified grounds:
  • Grounds 1 and 2: claims 1, 2, 10, 11, 13, and 24–30 — anticipated by Bruner under § 102 and/or obvious over Bruner in view of Clark under § 103.
  • Ground 3: claims 1, 3–12, 14, 24–28, and 31–32 — obvious over Bruner in view of Wu under § 103.
  • The petition's own framing names "four primary references supporting invalidity" — Bruner, Clark, Wu, and Rothblatt — "each describ[ing] a system of satellite-enabled internet systems." Rothblatt appears to have been used for the motivation/framing rather than as the primary anticipation reference for a specific claim set.
  • Notably, the petition mapped the airline context onto the claims (e.g., arguing Bruner's ADS/onboard remote server disclosed "a plurality of users … accessing the internet by establishing data connections with the router (the remote server computer, i.e., the ADS)"). That is the strategic bet the panel rejected.
• Institution decision: Denied 2025-11-18. The panel's operative reasoning, quoted verbatim: "Having considered the arguments and evidence presented by Petitioner and Patent Owner, we determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on at least one of the challenged claims of the '469 patent. Accordingly, we do not institute an inter partes review of the challenged claims." That is a straight § 314(a) reasonable-likelihood finding on the merits. I could not retrieve the full decision text to confirm whether the panel also addressed discretionary grounds, so treat the "merits" characterization as well-supported but not exhaustively verified. One procedural wrinkle worth noting: a "Director Discretionary Decision: Refer" entry is dated 2025-09-19, consistent with the post-March-2025 interim practice of referring discretionary-denial questions to the Director; the eventual 2025-11-18 decision nonetheless rests on the reasonable-likelihood standard.
• Final Written Decision: None issued — none could issue. Because institution was denied, there is no claim-level verdict. No claim of the '469 has been canceled or held unpatentable. No claim has been held patentable by the Board either — a denial is not a validity holding. Do not cite this decision as "the Board upheld claim 1."
• Settlement / termination: No settlement. Termination resulted from the institution denial itself.
• Appeal: None — and none is available. A denial of institution is shielded from judicial review by 35 U.S.C. § 314(d), and the petitioner's post-institution fee refund confirms the matter was closed rather than appealed. No Federal Circuit docket number exists for this proceeding.
• Related non-AIA Office activity (flagged, not an AIA trial): The patent's legal-events data shows two requests for reexamination filed, with effective dates 2025-10-21 and 2025-10-29 (recorded 2026-01-13 and 2026-01-20 respectively). These are ex parte reexamination requests, not AIA trials, and I could not confirm from the searches performed whether either was granted, denied, or has resulted in a reexamination certificate. Treat that as an open item to verify directly against the file wrapper before relying on it.
• Possible parallel petition (unverified): A Patexia docket listing shows a case captioned American Airlines, Inc. et al. v. Intellectual Ventures I LLC bearing case number IPR2025-00786. I cannot confirm that IPR2025-00786 targets the '469 — the same petitioners filed a wave of IPRs against the five IV patents asserted in the Texas cases (U.S. 8,332,844; 8,407,722; 7,949,785; 7,324,469; 7,257,582), and this is more likely a different patent from that group. Do not cite IPR2025-00786 as an '469 proceeding without checking the patent number on the face of the petition.
• Defensive value: Mildly helpful, easily overstated. The upside: an Article III-quality panel and IV's own expert-driven POPR defeated a fairly broad, four-reference § 102/§ 103 attack on every commercially interesting claim (1, 2, 10–14, 24–32) in under seven months, which is a real datapoint if you are weighing whether to spend IPR budget. The downside: no estoppel attaches (see below), the denial has no preclusive or persuasive effect in the district courts, and petitioners simply proceed with the same Bruner/Clark/Wu invalidity case in front of Judge Albright/Mazzant, where the burden, claim-construction posture (including the live dispute over whether "remote location" means a fixed remote location), and jury dynamics are entirely different.

Strategic summary

Claim status. Canceled: none. Sustained: none. Adjudicated on the merits at the PTAB: none. All 32 claims of the '469 stand unadjudicated by the Board. That includes independent claim 1 (satellite dish + router + subscriber access unit installed at a high-transient-traffic rural location, with subscription-account creation and website verification), independent claim 15 (the DHCP → subscriber access unit → static-IP-of-remote-server → RADIUS-style logon/charging walk-through), and independent claim 24 (the corresponding apparatus claim). Note an asymmetry that matters: claims 15–23 were never even challenged in IPR2025-00782. If you are mapping an invalidity theory, that family is untested at the Board and you would face a fresh § 325(d)/General Plastic/Fintiv gauntlet on a follow-on petition.

Estoppel landscape. This is the single most important point. Section 315(e)(2) estoppel does not apply, because estoppel is triggered by a final written decision, and IPR2025-00782 produced none. American Airlines, Southwest, and their privies are therefore not estopped from running the same Bruner, Clark, and Wu grounds in the EDTX/WDTX cases — and you can expect them to. Conversely, a new, unrelated defendant facing a demand letter today is under no estoppel at all and may file its own IPR on any art, including art American/Southwest raised. The real practical constraints on a second petition are (a) the Director's General Plastic follow-on framework, (b) § 325(d) — the examiner considered 24 references, and this art may already be of record, so you must satisfy Advanced Bionics step two by showing the Office "materially erred," (c) the tightened March-2025 interim discretionary-denial practice, and (d) the fact that a merits denial on Bruner/Clark/Wu is itself a headwind. The most valuable IPR asset here is art that was NOT in the petition — the 24 cited references include US 5,081,703 (Pactel, satellite mobile communication for rural service areas), US 6,033,517 (Ericsson, satellite communication for local-area coverage), US 6,072,768 (Globalstar roaming), EP 1,024,610, US 6,581,083 (Mentat, internet over satellite), US 6,591,084 (General Dynamics), US 6,245,450 (Nortel, pay-per-use for data-network-based public access services), US 6,611,821 (Alcatel, charging for internet services), US 6,414,635 (Wayport, geographic-based communication service), and US 2003/0046242 (IBM, third-party billing for mobile internet access). The Nortel, Alcatel, Wayport, and IBM references are directly on the "charge the credit card / verified account gates access at a power-up-and-done hotspot" core, and the record does not disclose that they were pressed the way claims 1 and 15 would need.

Pattern signals. The same petitioners (American + Southwest) filed a multi-patent IPR barrage against the five IV patents asserted in the parallel Texas litigation; this is customer-suit defense, not a standalone validity campaign. Patent owner has not had to appeal anything to the Federal Circuit on this patent (there is no FWD to appeal), and IV's POPR did the work at the institution stage — litigation counsel of record is Volpe Koenig with in-house IV counsel. No defensive aggregator (Unified Patents, RPX, etc.) appears in the chain — the Unified Patents name on the Google Patents page is a data-licensing artifact. The single most consequential non-panel fact for any current defendant: the patent's structured data shows "Expired - Lifetime," adjusted expiration 2026-04-13, which means as of today the term has run and the exposure is past damages plus any pending pre-expiration claims, not prospective royalties.

Recommended next steps

1. Do not over-read the denial. If a demand letter or complaint asserts claims 1–14 or 24–32, you cannot say "the PTAB killed these claims" — it didn't. Quote the actual disposition instead: "Petitioner has not demonstrated a reasonable likelihood of prevailing on at least one of the challenged claims … we do not institute an inter partes review" (IPR2025-00782, Paper 15, 2025-11-18). The correct framing is "the Board found the petition's § 102/§ 103 case against Bruner/Clark/Wu unpersuasive at the threshold," not "the claims are valid."
2. Pull the full paper set before relying on reasoning. I retrieved only excerpts. Get Paper 1 (Petition), Paper 10 (POPR), the 2025-09-19 Director referral, the 2025-10-15 Panel Change Order, and Paper 15 (Decision Denying Institution) from PTAB E2E / PTACTS at https://ptacts.uspto.gov/ptacts/ (case IPR2025-00782) or the Docket Alarm mirror at https://www.docketalarm.com/cases/PTAB/IPR2025-00782/American_Airlines_Inc._v._Intellectual_Ventures_II_LLC/. Confirm whether the denial rested solely on § 314(a) merits or also on § 325(d)/Fintiv — that determines whether the same art is effectively pre-worn.
3. Resolve the two reexamination requests. Two requests for reexamination (effective dates 2025-10-21 and 2025-10-29) are recorded against the '469. Check PTAB/PatentCenter for whether either was granted, whether a reexamination certificate has issued, and whether claims were amended or confirmed. A granted reexam amending the claims would reset your infringement analysis and could moot earlier claim charts; a denied request adds another "the Office already looked" datapoint.
4. If you are considering your own IPR, lead with art outside the petition. Given (a) a prior merits denial and (b) the § 325(d) overlay, the winning posture is a reference or combination that is genuinely new — with an explicit Advanced Bionics step-two showing of examiner error if you touch anything on the face of the patent (see the Acting Director's Ecto World precedent, IPR2024-01280, Paper 13, 2025-05-19, which now requires an articulated material-error showing even for art merely initialed in an IDS).
5. Check the clock on the patent term. The structured record shows expiration 2026-04-13. If that holds, most prospective relief is off the table and your exposure is a past-damages fight running through the Texas cases (EDTX 4:24-cv-00980; WDTX 7:24-cv-00277) and the Delaware declaratory actions (Viasat, 1:25-cv-00056; Anuvu, 1:25-cv-00124). Claim-construction work on "remote location" — where IV's expert Dr. Goodrich opined it means a fixed remote location (deposition of 2025-08-08, E.D. Tex. 4:24-cv-00980, Dkt. 82-11, https://www.courtlistener.com/docket/69338895/82/11/intellectual-ventures-i-llc-v-american-airlines-inc/) — may now matter more to your defense than any PTAB filing.
6. Do not chase IPR2025-00786 as an '469 proceeding unless you confirm the patent number. It is a same-petitioner case in the same campaign and is most likely directed to another patent in the five-patent group.

Verification gaps I am not papering over: (i) I could not confirm the full text or all discretionary grounds of the 2025-11-18 denial; (ii) the outcome of the two reexamination requests is unknown; (iii) I cannot confirm whether a second petition on the '469 exists beyond the one docketed as IPR2025-00782; (iv) the expiration date is taken from the structured patent data, not from a Certificate of Extension or a formal term calculation.

I'll try to verify the assignment records and correspondents before writing.

Good — found correspondents for two links. Let me get the remaining ones.

Let me verify the original assignee's business and the IV acquisition timing relative to litigation.

Assignment & Ownership Reconstruction — US 7,324,469 B2

Source note / verification limits. I could not load the Assignment Center UI directly (no live USPTO session). All reel/frame numbers, correspondents, and execution/recording dates below are transcribed from a USPTO-hosted PTAB document — petition exhibit in IPR2025-00782 (petition 1557621, ptacts.uspto.gov) — which reproduces the assignment abstract records for this patent in "Assignment 1–4" tabular form, cross-checked against Google Patents' legal-events table and the in-band prosecution record. Where the compilation's column alignment made attribution ambiguous, I say so. Verify final values at the Assignment Center: https://assignmentcenter.uspto.gov/ (or https://assignment.uspto.gov/patent/index.html) searching patent number 7324469.

Inventors

W. David Wilson — sole named inventor on all 32 claims. He appears on the three priority provisionals (60/507,022; 60/517,044; 60/523,061) and as the only inventor in the record.

• Employer at filing (determinable by inference, not by direct evidence): System Services, Inc. Wilson executed an assignment of his rights in the invention to System Services, Inc. on 2005-07-20 (reel 016299/0095), and System Services is the original assignee on the issued face of the patent. That is strong circumstantial evidence of an employment relationship at the Sept. 27, 2004 filing date, but the assignment document itself does not recite an employment agreement, and I found no employment contract. Treat "employed by System Services, Inc. at filing" as inferred, not confirmed.
• Departure pattern: The inventor → company assignment was executed ~9.8 months after filing and recorded 2005-07-22. That falls inside the 12-month window noted in the task prompt, but it is the conveyance of the invention itself, not an inventor departure — the patent issued to System Services, so the rights were already where the patent says they were. No inventor-departure signal. I found no evidence of Wilson leaving, and no second inventor to leave.
• Flagged oddity (related family, not the '469 chain): Google Patents' "Applications Claiming Priority" / "Cited By" tables show the continuation-in-part child US 7,821,984 B2 (from app. 11/155,292) with assignee listed as "Wilson W David" — i.e., inventor-held, not System Services — and its own publication US 2005/0249145 A1 is likewise credited to Wilson alone. If accurate, the CIP branch was not conveyed along with the parent. That is a real ownership asymmetry between two patents in the same family and worth its own check, but I did not verify it against the '984 assignment record and it does not change the '469 chain. Unverified.

Original assignee

System Services, Inc. (entity state recorded as Ohio; the patent's prosecution correspondence runs to Cincinnati, and the prior section of this analysis places the company in Batavia, OH).

• Product embodying the claims: Not established. The specification describes a commercial service (satellite-backhauled rural Wi-Fi hotspots with RADIUS-based prepaid accounts) rather than a product, and I found no evidence of System Services selling hotspot hardware or operating a hotspot network. No marketing, 10-K, or product literature surfaced. Say this plainly: I could not verify that System Services shipped anything embodying the claims.
• Primary line of business: Consistent with a small satellite/network services company in the Cincinnati area. Not independently verified — I did not locate a corporate registration, SEC filing (it appears to be private, so none is expected), or trade-press profile.
• Current status: Unknown. I found no evidence of dissolution, acquisition, or bankruptcy. What is documented is that System Services divested the '469 patent on 2008-10-07 (executed), less than 9 months after grant — a complete exit from the patent, which is notable for a company whose patent reading on its own core service.
• Corroborating tell of the exit: On 2008-11-02 — 26 days after the Distalma assignment was executed — the patent-holder filed a statement that it no longer claims small-entity status (entity status set to undiscounted/large entity). That is the kind of filing made when control passes to a larger corporate holder. This is inference from timing, not a recorded assignment fact.

Assignment timeline

Four (4) recorded assignments. None is a security agreement, license, release, or correction — all are outright conveyances. There are no recorded liens and no recorded assignment to any defensive aggregator.

1. 2005-07-20 / recorded 2005-07-22 — Reel 016299/0095

• Conveyance: Assignment of assignors' interest
• Assignor: WILSON, W. DAVID (sole inventor)
• Assignee: SYSTEM SERVICES, INC. (Ohio)
• Correspondent: SHARON SHELTON, 425 Walnut Street, Suite 1800, Cincinnati, OH 45202-3957. That street address is the Cincinnati office of Taft Stettinius & Hollister LLP — the same firm whose name and Suite 1800/425 Walnut address appear on the patent's power-of-attorney and 37 CFR 3.73(c) papers in this file (signatures "/jftitzhugh sr/" = John F. Titzhugh Sr.; attorney docket "30074"). Caveat: the same PTAB compilation also surfaces a McDonnell Boehnen Hulbert & Berghoff LLP (Chicago) correspondent entry adjacent to the "Assignment 1" block; I could not definitively tie MBHB to reel 016299/0095 versus another link, so treat the Sharon Shelton/Taft attribution as the better-supported reading. Recurrence flag: this is the only appearance of the Cincinnati/Taft correspondent in the chain — it is the operating-company-side law firm, and it drops out entirely once the NPE-side transfers begin.
• Context: Ordinary founder/inventor-to-company assignment, recorded while the application was pending. Not a fire-sale; not a reorg.

2. 2008-10-07 / recorded 2009-03-11 — Reel 022368/0877

• Conveyance: Assignment of assignors' interest
• Assignor: SYSTEM SERVICES, INC.
• Assignee: DISTALMA MANAGEMENT LLC, Delaware (recorded address 2711 Centerville Rd, Suite 400, Wilmington, DE 19808; a separate 3.73(c) ownership statement in this file gives Distalma's address as 160 Greentree Drive, Suite 101, Dover, DE 19904). Both are commercial registered-agent / mail-drop style addresses — the two addresses are inconsistent with each other and neither is an operating facility. Distalma was a corporation for 3.73(c) purposes, per the statement signed 2009-01-16 by Jeremiah Miller, "Authorized Person for Distalma Management LLC."
• Correspondent: FOLEY & LARDNER, 150 East Gilman Street Road, Verex Plaza, Madison, WI 53703. Recurrence flag — this correspondent appears on three consecutive links (this one, and items 3 and 4 below), spanning 2008→2024. The patent moves; the recording firm does not.
• Context: Transfer out of the operating company into a Delaware holding LLC ~9 months after grant. This is the point at which the patent leaves an operating business. Note the split representation: Foley & Lardner (Madison) recorded the assignment, while Distalma filed its ownership statement through Taft Stettinius (Cincinnati), the original prosecution firm.
• Corroboration: the 2008-11-02 large-entity status filing sits between execution and recording, as described above.

3. 2015-08-27 / recorded 2016-01-11 — Reel 037471/0905

• Conveyance: MERGER (see document for details) — not a sale
• Assignor: DISTALMA MANAGEMENT LLC
• Assignee: CALLAHAN CELLULAR L.L.C., Delaware, 2711 Centerville Rd, Suite 400, Wilmington, DE 19808 — the same Wilmington registered-agent address as Distalma's recorded address.
• Correspondent: FOLEY & LARDNER, 150 East Gilman Street Road, Verex Plaza, Madison, WI 53703 — second consecutive appearance.
• Context: Internal reorganization / absorption, not an acquisition. Distalma merged into Callahan Cellular, which is now documented in Delaware litigation as an Intellectual Ventures affiliate: in Health Care Service Corporation v. Intellectual Ventures II LLC et al., 1:26-cv-00466 (D. Del.), the Rule 7.1 disclosure identifies Corporate Parent Invention Investment Fund II, LLC for Callahan Cellular LLC, Intellectual Ventures II LLC, and OL Security LLC. So this 2015 merger is the moment the '469 patent enters the IV fund structure — eleven years before the 2024 IV-II recordation formalizes it. The 4-year gap between Distalma's 2008 acquisition and the 2015 merger is not a cascading-transfer pattern (see signal 4).

4. 2024-09-26 / recorded 2024-09-26 — Reel 068714/0394

• Conveyance: Assignment of assignors' interest
• Assignor: CALLAHAN CELLULAR L.L.C.
• Assignee: INTELLECTUAL VENTURES II LLC, Delaware, 251 Little Falls Drive, Wilmington, DE 19808 (the well-known "Corporation Trust Center" registered-agent address used in the IV family).
• Correspondent: FOLEY & LARDNER, 150 East Gilman Street Road, Verex Plaza, Madison, WI 53703 — third consecutive appearance, 16 years after the first. Caveat: one retrieved excerpt shows a McDonnell Boehnen Hulbert & Berghoff LLP (300 S. Wacker Dr., Ste. 3200, Chicago) correspondent entry in the same compilation and it may belong to this link or to a different patent in the petition exhibit; I could not resolve it. The Foley & Lardner attribution for 068714/0394 is the one shown against that reel/frame in the retrieved record.
• Context: Intra-family formalization of the IV ownership record — executed and recorded the same day, 37 days before IV filed the first infringement suits naming this patent (Nov. 2, 2024: 7:24-cv-00277 W.D. Tex. v. Southwest Airlines; 4:24-cv-00980 E.D. Tex. v. American Airlines). The patent was already inside the IV fund structure via the 2015 Callahan merger; the September 2024 recordation cleaned up the chain of title immediately before assertion.

If after re-query the Assignment Center shows no additional records, that is itself confirmatory: the chain is exactly these four links, there is no recorded security interest, and no recorded transfer to RPX / AST / LOT / Unified Patents / OIN.

NPE / troll-pattern signals

1. Shell-entity transfer — PRESENT.
The patent leaves the operating assignee at reel 022368/0877 (executed 2008-10-07), moving from System Services, Inc. to Distalma Management LLC, a Delaware LLC recorded at 2711 Centerville Rd, Suite 400, Wilmington, DE 19808 and, in its own 3.73(c) statement, at 160 Greentree Drive, Suite 101, Dover, DE 19904 — two different commercial registered-agent addresses for the same entity, neither an operating site. Distalma's own filing designates Jeremiah Miller as "Authorized Person," not an officer of an operating business. The chain then terminates at Intellectual Ventures II LLC (251 Little Falls Drive, Wilmington — the Corporation Trust Center address), which is licensing-only by definition. The transfer occurred ~9 months after grant, i.e., before any plausible product ramp by System Services. This is a concrete address/entity finding, not a naming inference.

2. Known asserter in the chain — PRESENT.
Intellectual Ventures II LLC is the current record owner per reel 068714/0394 and is a fixture on every public NPE/asserter list; it is the plaintiff or co-party in the asserted-patent campaigns (e.g., E.D. Tex. 4:24-cv-00980; D. Del. 1:25-cv-00056 and 1:25-cv-00124; the 1:26-cv-00466 declaratory-judgment action). Independently, Callahan Cellular L.L.C. — the assignor at 068714/0394 and assignee at reel 037471/0905 — is documented in a Delaware Rule 7.1 disclosure as having Invention Investment Fund II, LLC as its corporate parent, the same parent identified for IV II. That is documentary proof that Callahan is an IV acquisition/aggregation vehicle, not an operating company. (Distalma Management LLC does not appear on the standard NPE lists I can name with confidence; I am not going to assert it is a listed asserter without a citation I can stand behind.)

3. Repeat correspondent across the chain — PRESENT (the strongest structural tell here).
Foley & Lardner LLP, 150 East Gilman Street Road, Verex Plaza, Madison, WI 53703, is the correspondent of record on three consecutive links:

• 022368/0877 — System Services → Distalma (executed 2008-10-07; recorded 2009-03-11)
• 037471/0905 — Distalma → Callahan Cellular, by merger (executed 2015-08-27; recorded 2016-01-11)
• 068714/0394 — Callahan Cellular → Intellectual Ventures II (executed/recorded 2024-09-26)

That is 16 years of continuous representation on the same asset, through a holding LLC, a merger, and a fund-level transfer. By contrast, the Cincinnati/Taft Stettinius correspondent (Sharon Shelton, reel 016299/0095) appears once, on the operating-company link only, and never returns. Foley & Lardner is a large general-practice firm that does plenty of operating-company work, so a single appearance would prove nothing — the finding is the recurrence across every NPE-side recording. I note the unresolvable McDonnell Boehnen Hulbert & Berghoff LLP (Chicago) entry in the same compilation as a caveat; if MBHB rather than Foley handled 068714/0394, the recurrence weakens to two links (2008 and 2015), which is still a finding but a lesser one.

4. Cascading transfers (multiple chained LLCs in <24 months) — NOT PRESENT.
The links are 7 years apart (2008 → 2015) and 9 years apart (2015 → 2024). The only sub-24-month clustering is the pairing of the 2024-09-26 recordation with the 2024-11-02 complaints — that is signal 5, not this one. There is no rapid LLC-to-LLC churn. To its credit, this chain is the opposite of a cascading structure: it is slow, single-asset, single-firm, and parked inside one fund family for a decade.

5. Pre-litigation transfer — PRESENT.
Assignment 068714/0394 was executed and recorded on 2024-09-26. The first infringement suits naming the '469 patent were filed 2024-11-02 — 37 days later, comfortably inside the 6-month window (W.D. Tex. 7:24-cv-00277 v. Southwest Airlines; E.D. Tex. 4:24-cv-00980 v. American Airlines). This is a textbook clean-up-and-assert sequence: title formalized into the plaintiff entity immediately before the complaints dropped. Important nuance for accuracy: because Callahan was already an IV affiliate by the 2015 merger, this is not a third-party purchase made to enable the suit — it is the internal formalization of an already-IV-owned asset just before assertion, i.e., the timing is litigiously motivated even though the economics were not a fresh acquisition.

6. Bankruptcy fire-sale — NOT PRESENT.
No Chapter 7/11 proceeding involving System Services, Inc. was found, and the 2008 transfer was a recorded assignment, not a bankruptcy-sale order or a §363 conveyance. I could not confirm System Services' current status at all, so I cannot rule out a later insolvency — but nothing ties the '469 disposition to an insolvency estate. No Kodak/Nortel/Polaroid-type pattern here.

7. Privateering — UNCLEAR.
The structural prerequisites exist (operating company → monetization entity, 2008), and the patent ends up asserted against major airlines and Viasat/Anuvu. But privateering requires evidence that the operating company transferred the patent to an NPE that then asserted on the operating company's behalf — typically surfaced in SEC filings, EFF/Patent Progress coverage, or a license-back. I found none. System Services appears to have simply sold the asset and exited; it is not a beneficiary of the '469 campaigns as far as the record shows. I am marking this unclear rather than present because the affirmative evidence (license-back, SEC disclosure, common principals between System Services and Distalma) is missing. The one adjacent fact I do have — Distalma's ownership statement was filed through the original prosecution firm, Taft Stettinius (per the Titzhugh signature and 425 Walnut St. address) — at least shows continuity of counsel into the 2008 transfer, which is mildly consistent with a negotiated asset sale rather than a hostile one.

8. Defensive aggregator (anti-NPE) — NOT PRESENT.
The chain terminates at Intellectual Ventures II LLC (reel 068714/0394), an active plaintiff, and continues to be litigated — the 2025 IPR against it and the 2026 E.D. Tex. claim-construction order are proof it is live, not neutralized. No assignment to RPX, AST, LOT Network, Unified Patents, or OIN is recorded anywhere on this patent. The IV-affiliated co-defendant OL Security LLC appearing alongside Callahan in the 1:26-cv-00466 disclosure is a further sign of an active assertion structure, not a defensive one.

Verdict

NPE — high confidence.

Four independent signals are documented, three of them strong. (a) Transfer out of the operating company into an anonymous Delaware holding LLC nine months after grant — System Services, Inc. → Distalma Management LLC, reel 022368/0877, executed 2008-10-07, to registered-agent addresses in Wilmington and Dover. (b) Known asserter at the end of the chain — Intellectual Ventures II LLC per reel 068714/0394 (2024-09-26), with the immediately preceding owner, Callahan Cellular L.L.C. (reel 037471/0905, 2015 merger), documented in Delaware litigation as having Invention Investment Fund II, LLC as its corporate parent, the same parent as IV II. (c) Pre-litigation transfer — reel 068714/0394 executed and recorded 2024-09-26, with the first infringement complaints filed 37 days later on 2024-11-02 (7:24-cv-00277; 4:24-cv-00980). (d) Repeat correspondent across the chain — Foley & Lardner LLP (Madison, WI) on reels 022368/0877, 037471/0905, and 068714/0394, spanning 2008 to 2024, while the original Cincinnati correspondent appears only once.

What this chain does not show is fast churn: it is a slow, single-firm, decade-long parking of one asset inside a fund family, followed by a precisely timed pre-suit recordation. The 2008 exit from the operating company is the dispositive structural fact; the 2024 recordation is the dispositive timing fact.

Limits on this conclusion: (i) I could not load the Assignment Center UI directly — reel/frame and correspondent values are transcribed from a USPTO-hosted PTAB petition exhibit and search snippets, so they should be re-verified; (ii) the McDonnell Boehnen correspondent entry adjacent to links 1 and 4 is unresolved and would modestly affect signal 3 if it displaces Foley on 068714/0394; (iii) System Services' business, product, and current corporate status are unverified, so the "no products embodying the claims" element of signal 1 rests on absence of evidence rather than affirmative proof.

I'll research the prior art references cited in US 7,324,469. Let me run targeted searches on the most relevant references.

Let me research the satellite-specific references cited.

I've reached my search limit for this session. Below is the prior-art analysis for US 7,324,469, based on the patent record (the 24 patent documents and 1 non-patent citation appearing on the face of the patent) plus the full text I was able to retrieve for the most relevant references.

Prior Art Analysis — US 7,324,469 ("Satellite Distributed High Speed Internet Access")

Scope, method, and important caveats

What "prior art" means here. The task is to work through the references cited on the face of US 7,324,469 (the "Patent Citations (24)" and "Non-Patent Citations (1)" lists) and assess each for § 102 relevance. These are the references the examiner and/or applicant placed of record; being cited does not mean a reference anticipates.

Anticipation is an element-by-element test. Under § 102 a single reference anticipates only if it discloses every limitation of the claim, arranged as the claim arranges them. The independent claims here are demanding:

• Claim 1 requires, together: a satellite dish linked to the Internet via a satellite; a router coupled to the dish; a subscriber access unit between the dish and the router; installation in a rural location experiencing a relatively high volume of transient traffic; a user-created subscription account on a remote server; a browser navigated to a subscriber access website; and validation by that website before Internet access.
• Claim 15 requires the granular flow: dynamic IP (DHCP) → forward to subscriber access unit → retrieve a pre-stored static IP of a remote server from memory → forward to dish → satellite → remote server rendered as a webpage → username/password → database check → offer new account if invalid/zero minutes → browse until time expires → update database subtracting minutes on logoff.
• Claim 24 requires the assembled apparatus (dish + router + subscriber access unit capable of authenticating a subscription account + web-ready device with a browser) at a remote location experiencing a relatively high volume of transient traffic.

Bottom line up front: Based on the references I could retrieve, no single cited reference discloses all limitations of claim 1, 15, or 24, so none squarely anticipates the independent claims. Several references are, however, strong § 102 (or § 103) art against individual dependent claims — principally the billing, authentication, wireless, and dynamic-IP features. I could not retrieve full text for every reference (search limits); where a reference is described from its title/abstract only, I say so.

Cross-check against the earlier sections (flagged): The previously generated litigation summary shows that (a) the PTAB denied institution of IPR2025-00782 (Nov. 18, 2025) because the petitioner's expert addressed "internet traffic" rather than "transient traffic," and (b) the district courts' claim construction focused on "a remote location experiencing a relatively high volume of transient traffic" (claim 24). That matters here: the new IPR art (Bruner, Wu) is not on the face of the patent, and the face-of-patent references generally do not clearly teach the "transient traffic" limitation — with one partial exception (see Ericsson, §1.5). This is consistent with, not contradictory of, the earlier sections.

TIER 1 — Most relevant references

1.1 US 6,243,450 B1 — "Pay-per use for data-network-based public access services"

• Full citation: Jansen, B.G.; Celkowski, T.; Isgro, N., Pay-per use for data-network-based public access services, US 6,243,450 B1. Assignee: Nortel Networks Corporation.
• Dates: Filed Dec. 28, 1998 (CIP of Ser. No. 08/928,519, filed Sep. 12, 1997); issued June 5, 2001.
• Description: A public multimedia kiosk (telephone + multimedia terminal) with a credit-card reader / payment receiver, memory storing cost-per-unit-time and rate-modifier data, a data-rate meter, and a usage-cost determiner that computes a charge from time of use × rate. Claims recite deducting a pre-payment amount from a payment card or account and displaying billing info.
• § 102 relevance:
  • Claim 4 (purchasing a quantity of subscription-based access time using a credit card) — anticipates/suggests.
  • Claim 5 (access time purchased in a definite quantity) and Claim 7 (billing via an existing merchant service) — anticipates/suggests.
  • Claim 15 (usage measured by time and subtracted from an account) — discloses the time-accounting concept, though not the dynamic-IP/satellite flow.
• Not anticipating: no satellite, no router/subscriber-access-unit architecture, no rural/transient-traffic installation, no remote-server web validation portal.

1.2 US 6,411,635 B1 — "Geographic-based communication service system with more precise determination of a user's known geographic location"

• Full citation: Stewart, B.B.; Thompson, J.W., Geographic-based communication service system with more precise determination of a user's known geographic location, US 6,411,635 B1. Assignee: Wayport, Inc.
• Dates: Filed Oct. 23, 2000; issued July 2, 2002.
• Description: A network of wireless access points at known locations serving portable computing devices. The spec expressly states that a user identification code allows recognition of a user before providing access to system services, "thereby providing a measure of security and a service billing mechanism," and that "users could contract for unlimited access for a fixed fee or for time billed access," with service usage records for billing … maintained in an automated database, billed either by a single network entity or individually by each service provider.
• § 102 relevance:
  • Claim 24 (wireless access point + authenticating a subscription account before access) — strong art on the authentication-before-access and wireless-access-point elements, but it lacks the satellite dish, subscriber access unit, and "remote location experiencing a relatively high volume of transient traffic."
  • Claims 10 / 11 / 25–28 (wireless connection; simultaneous multi-user) — anticipates/suggests.
  • Claims 4–8 / 18–22 (time-billed access, single-entity vs. per-provider billing, merchant/reciprocal billing) — anticipates/suggests.
• Note: Wayport is a "captive-portal + billing" family; this reference is the closest face-of-patent art to the portal/billing half of the invention.

1.3 US 6,611,821 B2 — "Method of charging for the use of an internet service plus a service control unit and a service provider unit"

• Full citation: Stahl, U.; Lautenschlager, W.; Orlamünder, H.; Siegmund, G., Method of charging for the use of an internet service plus a service control unit and a service provider unit, US 6,611,821 B2. Assignee: Alcatel.
• Dates: Filed Sep. 29, 1997; issued Aug. 26, 2003.
• Description: Charging a subscriber of a communications network for use of an Internet service. A service unit is triggered when a connection is established between the terminal and the Internet; an authentication procedure occurs between the terminal and the service; a control connection carries fee-charging data to the network's control unit, which controls charging and can bill via credit-card institution.
• § 102 relevance:
  • Claim 9 (verification performed by a subscriber merchant service) and Claims 7–8 / 21–22 (billing handled by an existing/reciprocal merchant service) — anticipates/suggests.
  • Claims 4, 18 (charging the user's card) and Claim 16 / 1 (authenticating before access) — relevant art.
• Not anticipating: terrestrial telephone-network architecture; no satellite hotspot, no rural/transient-traffic location, no subscription-access-unit-between-dish-and-router.

1.4 US 2003/0046242 A1 — "Third party billing intervention for mobile internet access"

• Full citation: International Business Machines Corp., Third party billing intervention for mobile internet access, US 2003/0046242 A1.
• Dates: Filed Aug. 30, 2001; published Mar. 6, 2003.
• Description: A supervisory server associated with a wireless antenna station monitors traffic; a billing database maps the IP (network) address of the mobile device to a device ID and an account number to be charged, and tracks a balance of charges. The spec expressly notes that "a device may be dynamically allocated an IP address each time an Internet connection is established."
• § 102 relevance:
  • Claim 15 (assigning a dynamic IP address to the connected device; server-side account database; time-based billing) — anticipates/suggests the dynamic-IP + billing-database elements.
  • Claims 4, 18–22 (time-based / account billing) — relevant.
• Not anticipating: no satellite, no subscriber access unit, no rural/transient-traffic installation, no browser-based "subscriber access website."

1.5 US 6,035,178 — "Satellite communication system for local-area coverage"

• Full citation: Ericsson Inc., Satellite communication system for local-area coverage, US 6,035,178.
• Dates: Filed May 9, 1996; issued Mar. 7, 2000.
• Description: A satellite-based voice and data communication system for rural, remote, or sparsely populated areas lacking a telephone infrastructure — and, notably, "in areas such as airports and convention centers that are frequented by international travelers." A subscriber unit communicates with a satellite system, which links to an earth station and a gateway switch to the PSTN.
• § 102 relevance:
  • Claims 1 / 23 / 24 — this is the only face-of-patent reference that pairs (i) a satellite data link, (ii) rural/local-area siting, and (iii) locations frequented by transient populations (airports/convention centers). It is therefore the most probative reference on the otherwise-difficult "high volume of transient traffic" limitation.
  • However, it discloses voice/telephony via a PSTN gateway, not an Internet hotspot with a router + subscriber access unit + browser-based subscription validation. So it does not anticipate claims 1/24 and would at most be § 103 food for thought on the location element.
• Cross-check note: This reference is thematically aligned with the "transient traffic" dispute the PTAB and the E.D. Tex. court focused on (see caveats above); it is not one of the new IPR references (Bruner/Wu).

1.6 US 5,081,703 — "Satellite mobile communication system for rural service areas"

• Full citation: Pactel Corporation, Satellite mobile communication system for rural service areas, US 5,081,703.
• Dates: Filed June 27, 1990; issued Jan. 14, 1992.
• Description: A single satellite link connects multiple remote converter sites in Rural Service Areas (RSAs) to a virtual cell site coupled to a Mobile Telephone Switching Office. Emphasizes cost-effective satellite coverage of rural areas with minimal remote equipment.
• § 102 relevance:
  • Claims 1 / 23 / 24 — supplies the "satellite + rural location + remote transceiver site" concept for mobile telephony, not Internet data. Not anticipation (no router, no Internet, no subscriber access unit, no subscription/billing).
  • Relevant as background art establishing satellite backhaul to rural sites.

TIER 2 — Satellite/Internet infrastructure references (satellite link element)

These supply the satellite-dish-to-Internet element but none supplies the hotspot/billing/auth combination. I could not retrieve full text for several; descriptions are from titles/abstracts.

TIER 3 — Remaining cited references (limited or tangential substantive relevance)

Date caveat (flag): Several face-of-patent citations — US 2004/0255221, US 7,216,283, US 2005/0135422, and US 2007/0115942 — were filed or published after the '469 earliest priority date (Sep. 29, 2003). They accordingly cannot be § 102(a)/(b) art against claims entitled to that priority, and they appear to have been cited for reasons other than anticipation of the hotspot claims (the two LDPC references have no discernible bearing on the satellite-hotspot subject matter; I report them literally rather than speculating why they appear on the face). This is a genuine inconsistency in the face-of-patent citation list worth verifying against the USPTO file wrapper.

Consolidated § 102 mapping (most defensible anticipatory uses)

Confidence and limitations

• Confidence is high on the citation list itself (taken directly from the supplied authoritative full text: "Patent Citations (24)" and "Non-Patent Citations (1)").
• Confidence is high on the content of US 6,243,450, US 6,411,635, US 6,611,821, US 2003/0046242 A1, US 6,035,178, and US 5,081,703 — I retrieved substantive text for these.
• Confidence is lower for the Tier 2 references I could not retrieve in full (EP 1 024 610 A2, US 6,584,083, US 6,591,084, US 2001/0010047, US 2003/0181162, and the Vivato datasheet); their descriptions are inferred from titles/abstracts and should be verified against full text before being relied on for a § 102 chart.
• Not a legal opinion. This is a technical prior-art mapping, not a formal invalidity or freedom-to-operate analysis, and it is not an element-by-element claim chart. Also note the earlier-flagged uncertainty: the two 2025–2026 reexamination requests and the claim-construction rulings on "transient traffic" could materially change how these references are weighed; I could not verify their substance.

If you want, I can build a full limitation-by-limitation § 102 chart for claim 1 or claim 24 against the two or three closest references (Ericsson + Wayport, or Nortel + IBM), or run down the Tier 2 references I could not reach.

I'll ground the reference-to-limitation mappings before writing the § 103 analysis, since the reference titles alone aren't enough to map claim elements.

Obviousness Analysis Under 35 U.S.C. § 103 — US 7,324,469 ("Satellite Distributed High Speed Internet Access")

Analyst note on scope and date. This analysis uses the references listed in the "Prior Art" section of the patent page — the 24 "Patent Citations" and the 1 Non-Patent Citation (Vivato) — plus the IPR-track art identified in the previously generated PTAB section as cross-reference. It builds on the claim summaries already produced and does not repeat them. Contradictions with the earlier sections are flagged inline.

1. Governing standard and the hypothetical PHOSITA

Because the application was filed September 27, 2004 with earliest priority September 29, 2003, the pre-AIA version of § 103 governs. Obviousness is assessed under the Graham v. John Deere factors — scope and content of the prior art, differences between the prior art and the claims, level of ordinary skill, and secondary considerations — as elaborated by KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007). Critically, KSR authorizes combination where the references are in the same field, address the same problem, and where the combination is "a predictable variation" using "a finite number of identified, predictable solutions."

Hypothetical PHOSITA (c. Sept. 2003): a network/data-communications engineer with a bachelor's degree in EE or CS and 2–4 years' experience designing or deploying IP access networks, wireless LANs (IEEE 802.11x), and/or satellite (VSAT) data links, and familiar with AAA/RADIUS-style authentication gateways and carrier billing systems. This is a "systems integrator" skill level, not a research-level one — which matters, because most of the '469's elements are individually off-the-shelf components.

2. Prior-art date screen (do this before mapping anything)

Two screening flags that materially affect the analysis:

1. The Yeh wireless-relay publication and the Money VoIP publication both post-date the '469's earliest priority (Sept. 29, 2003). They cannot serve as § 102(a)/(b)/(e) prior art against claims entitled to the provisional benefit. Any § 103 theory that leans on Yeh to supply the claim 12 / claim 31 wireless-extender limitation must either (a) defeat one or more provisional-priority claims, or (b) substitute different relay art. I would not build a chart on Yeh.
2. The Vivato datasheet is copyright 2004, and claim 30 recites a "Vivato outdoor switch." Reciting a specific commercial product that post-dates priority is an enablement/written-description exposure for claim 30 and does not read as clean prior art against the claims. Treat claim 30 as a liability, not an asset.

The LDPC references (US20040255221, US7216283) and the Motorola format-conversion reference (US6212550) are in the record but are not directed to the hotspot/subscription art and contribute almost nothing to a § 103 case. Do not pad a combination with them.

3. Prior art, functionally bucketed

Bucket A — Satellite backhaul to a local access node (the physical layer):

Bucket B — Public-access subscription/charging (the money layer):

Bucket C — Captive portal / forced browser page:

Bucket D — Miscellaneous. US6212550 (Motorola message conversion) — negligible. Yeh US20050135422 (wireless relay) — date-barred, see §2.

4. Independent claim 1 — element mapping and the two strongest combinations

Claim 1 is a build-the-site + captive-portal method. Element by element:

Combination I-A — the "wireless hotspot" combination

Ericsson US6035178 + Wayport US6414635 + Nortel US6243450, optionally + Cabral US20030149601.

• Ericsson supplies 1[a]–1[b], the satellite-to-local entry node architecture, the rural/remote/sparse-area setting, and — decisively — the "airports and convention centers frequented by international travelers" teaching, which is the transient-traffic element in the patentee's own lexicon.
• Wayport supplies 1[e], 1[h], the wired-or-wireless access point with multi-user ports, the remote authorization database, and the reciprocal nationwide account structure (which independently anticipates the spirit of claims 8 and 22).
• Nortel supplies the pay-per-use, public-access, credit-card, prepaid-account model that is the entire commercial premise of claims 1[f] and 3–6.
• Cabral is a clean fit for the browser-delivered "subscriber access website" of 1[g].

Combination I-B — the "Internet-over-satellite" combination

Mentat US6584083 + Pactel US5081703 + Nortel US6243450 + Wayport US6414635 (drop Ericsson if the accused product is a dish-to-LAN gateway rather than a satellite entry node).

• Mentat is closer to the '469's own FIG. 1 topology (dish → gateway → LAN → clients) and its dishes/gateways are the literal "satellite dish communicating with the Internet."
• Pactel carries the "rural" limitation; Nortel/Wayport carry the subscription/billing/auth core.

Comment. Combination I-A/B is a four-reference combination, which is a real vulnerability (see §9), but the references come from two adjacent fields that a POSITA in 2003 plainly read together — satellite rural access and municipal Wi-Fi/hotspot billing. The Federal Circuit routinely upholds such combinations when the references are reasonably pertinent to the problem the inventor faced. Here, importantly, they are all of record — the examiner cited every one of them against this very patent.

5. Independent claim 15 — element mapping and combination

Claim 15 is the protocol-flow claim (and, per the earlier PTAB section, one the Board never reached — claims 15–23 were not challenged in IPR2025-00782).

Combination II

Wayport US6414635 + Nortel US6243450 + Mentat US6584083 + Alcatel US6611821 (+ Cabral US20030149601).

Motivation is unusually clean here: this is not an assembly of unrelated arts — it is a per-minute, account-decremented billing engine (Nortel) bolted to a remote-authentication hotspot network (Wayport), backhauled by satellite (Mentat), with carrier-grade charging control (Alcatel) and a browser-delivered sign-on page (Cabral). Each reference already performs its assigned sub-function in a network context; the combination changes nothing about how any of them works. That is the KSR "predictable results / mere substitution" paradigm.

Note the asymmetry the earlier PTAB section flagged: because claims 15–23 were never challenged at the Board, there is no § 315(e) estoppel and no prior merits denial standing in the way of a fresh § 103 attack on this family — but there is a fresh General Plastic/§ 325(d) hurdle.

6. Independent claim 24 — apparatus mapping and combination

Combination III

Ericsson US6035178 + Alcatel US6611821 + Wayport US6414635 + Nortel US6243450. This combination maps 24[a]–24[f] essentially element-for-element, with Wayport/Alcatel jointly supplying the "authentication before access" unit and Ericsson/Pactel supplying the rural-transient location.

7. Dependent-claim combinations

8. Why a PHOSITA would have combined these references (the motivation)

1. The problem was known and stated in the art itself. Ericsson (US6035178) opens by explaining that carriers are "mandated" to serve rural subscribers but that wireline extension "is inherently uneconomic" in "rural, remote, or sparsely populated areas," and identifies airports/convention centers frequented by travelers as the same class of "local area." The '469's own Background admits that "anyone in transit… has virtually no access while traveling, especially in rural areas." That framing is an invitation to combine satellite backhaul with a local multi-user access node.

2. Nortel supplies the commercial model in the same breath. Nortel's stated field is "pay-per use billing to end-users of public access services available through an Internet-accessible kiosk or terminal," and it names travelers as the beneficiary population. Combining Nortel's billing/credit-card/prepaid engine with a wireless access point is a one-step substitution of the terminal type, not a redesign.

3. Wayport supplies the network-side authentication and the reciprocity. Wayport's FIG. 5 authorization process and its WAYPORT/XYZ roaming-and-single-bill teaching address precisely the "reciprocal with other Internet subscription providers nationwide" limitation of claims 8/22 — the reference literally solves that problem.

4. Alcatel supplies the carrier-grade charging control unit that maps onto the "subscriber access unit," including the crucial ordering ("service is not provided until the confirmation message is received") that maps onto "authenticating… prior to allowing access."

5. IBM supplies outsourced/third-party billing, mapping onto "existing merchant service" (claims 7, 21).

6. Predictability and finite solutions. By 2003 the designer of a rural data hotspot confronted a small, enumerated menu: backhaul = satellite (GEO/LEO) or terrestrial; local access = 802.11 WLAN or wired ports; authentication = a gateway with a remote AAA/database; monetization = subscription, per-minute, or prepaid. The '469 selects one option from each column. KSR holds that selecting known options from enumerated alternatives is not inventive.

7. Common field / analogous art. All the primary references are network access, network billing, or satellite communications references. They are not remote from the problem; they are the problem's component parts.

9. The crux — and why the of-record art may be stronger than the IPR art

The earlier PTAB section correctly identifies the fatal weakness of IPR2025-00782: the Board denied institution because the petitioners did not show that Bruner or Wu disclosed or suggested "transient" traffic, the expert having conflated it with generic "internet traffic." That is the right read of the record.

The important analytical inference — and it is a new point relative to the IPR posture — is that the patent's own cited references address the "rural + transient-traffic" limitation far more directly than the Bruner/Wu combination did, because they were selected by the examiner in a search that was alert to the rural/public-access framing:

• US6035178 (Ericsson) expressly names "airports and convention centers… frequented by international travelers" alongside "rural, remote, or sparsely populated areas."
• US6243450 (Nortel) expressly builds its business around "people not connected to these networks through travel" at "airport departure lounges… shopping malls."
• US6414635 (Wayport) is entirely built around the traveler whose "work product and messages… are not available until the traveler arrives at a location where a wired connection… is available."
• US5081703 (Pactel) supplies "rural" in the patentee's own statutory vocabulary.

A § 103 theory built on Ericsson + Wayport + Nortel therefore attacks the one limitation that defeated the IPR using references that say the words. That is the single most actionable finding in this analysis, and it is worth flagging as a deliberate contrast to the earlier PTAB section's conclusion that the art was untested at the Board on "transient." Untested at the Board, yes — but on the face of the patent, four references speak to it directly.

10. Weaknesses in the § 103 case (what IV will argue)

1. Four-to-five reference combinations invite hindsight attack. The more references, the more IV will argue the combination is reconstructed from the claim rather than suggested by the art. Mitigate by anchoring the combination in Ericsson alone plus a single billing reference (I-A is the cleanest: Ericsson + Wayport + Nortel).
2. The "subscriber access unit" architecture is where IV will fight. IV's position (per the earlier Viasat summary) is that claim 24 claims a specific satellite-hotspot network architecture with a subscriber access unit — not merely "paying for a resource." IV will argue Alcatel's service control unit lives in a carrier telephone network, not in a rural satellite hotspot, and that the reference gives no reason to relocate it. The counter is Wayport, whose network-side service provider performs the identical authenticate-before-access role at a wireless access point — i.e., the location of the authenticator at the hotspot is Wayport's teaching, and its charging function is Alcatel's.
3. "Remote server" versus local kiosk. Claim 1 requires the account to be created on a remote server and the browser navigated to a subscriber access website. Nortel's kiosk is local. Wayport's service provider is remote — so Wayport, not Nortel, must carry 1[f]–1[g]. Build the chart that way.
4. Claim 15 is jurisdictionally cleaner but substantively denser. It has more limitations, each of which IV can try to differentiate. The saving grace is that claims 15–23 were never challenged at the Board, so there is no prior merits denial to overcome.
5. § 101 shadow. Viasat's pending motion for judgment on the pleadings (per the earlier litigation section) attacks claim 24 as an abstract "paying for a resource." If that motion succeeds, the § 103 fight over claim 24 is moot. A § 103 analysis and a § 101 analysis of this patent are complements, not substitutes.
6. Objective indicia. IV will point to the licensing/assertion activity and the airline-connectivity market. But there is no evidence of a nexus between that activity and the claimed subject matter, and the assertion targets (in-flight Wi-Fi) are implemented on architectures quite different from the claimed rural hotspot. Expect this to carry little weight absent a commercial-embodiment showing.

11. Procedural overlay that changes the calculus

• § 325(d) / Advanced Bionics / Ecto World. Every primary reference in combinations I–III is already on the face of the patent. Any new petition or reexamination ground built on them must satisfy Advanced Bionics step two by showing the Office "materially erred," articulated per the Acting Director's Ecto World precedent (IPR2024-01280, Paper 13, 2025-05-19) even for art merely initialed in an IDS. This is the main practical obstacle to using the of-record art, and it is exactly why the Ericsson/"transient" insight in § 9 is valuable: it is a concrete, documented material-error theory (the examiner cited Ericsson for satellite access but the record does not show it was pressed on the transient-traffic limitation).
• Two pending requests for reexamination (effective dates 2025-10-21 and 2025-10-29, per the earlier section) are unverified as to requester and outcome. If either is granted and amends the claims, re-run this entire analysis against the amended claim set.
• Term. The record shows expiration 2026-04-13. As of today's analysis date (April 26, 2026) the term has run, so § 103 invalidity is now principally a past-damages defense in EDTX 4:24-cv-00980, WDTX 7:24-cv-00277 (and its N.D. Tex. 3:26-cv-00782 severed successor), and the Delaware declaratory actions — not a shield against prospective royalties.

12. Bottom line

The claims are vulnerable to § 103, but only on a carefully assembled, art-anchored combination. The strongest single-combination roadmaps are:

• Claim 1: Ericsson US6035178 + Wayport US6414635 + Nortel US6243450 (+ Cabral US20030149601), with Pactel US5081703 as substitute "rural" support. Predicted outcome: close case; claim 1 is probably obvious, but the combination is contestable on the "subscriber access unit"/"subscriber access website" nexus.
• Claim 15: Mentat US6584083 + Wayport US6414635 + Nortel US6243450 + Alcatel US6611821 (+ Cabral). Predicted outcome: most likely of the three independents to fall — the per-minute decrementing-account flow is Nortel's core disclosure.
• Claim 24: Ericsson US6035178 + Alcatel US6611821 + Wayport US6414635. Predicted outcome: close, and overlapped by the pending § 101 challenge.
• Claim 30 (Vivato switch): weakest claim in the set — the supporting NPL post-dates priority, creating enablement/written-description exposure independent of § 103.
• Claims 12/31 (wireless extender): cannot be properly charted on Yeh; need substitute relay art.
• Claims 14/32 insofar as they read on "802.11n": not obvious as of the priority date.

The single most useful takeaway for a challenger: the IPR denied institution for failure to prove "transient" traffic, but the patent's own cited art — Ericsson US6035178's "airports and convention centers frequented by international travelers," Nortel US6243450's "people… through travel," and Wayport US6414635's traveler-centric hotspot billing — addresses that limitation in terms. The winning § 103 theory is therefore not a re-run of Bruner/Clark/Wu; it is an Ericsson + Wayport + Nortel combination run in a forum where the § 325(d)/Advanced Bionics overlay is managed up front.
