US 7665130

I'll search for authoritative information on this patent number and any related 2026 litigation activity.

Let me check for any 2026 CAFC docket activity and litigation involving this patent.

Let me verify whether 7,665,130 itself appears in any 2026 CAFC appeal or is asserted in the pending district court case.

US Patent 7,665,130 — Summary

Caveat on method: I ran live searches (Google Patents, USPTO-linked sources, PTAB/PTACTS documents, CourtListener/dockets). I do not have direct query access to the CAFC's own docket database, so my CAFC statement below is based on search coverage, not a definitive docket check.

Bibliographic data (all confirmed against the patent text and search results)

Abstract

A system and method of providing network access comprising a processor, first and second network interfaces, storage media, and computer instructions executable to receive a network communication over the first interface from a user device and determine if the communication is associated with an authenticated user. If the communication is not authenticated, is not destined for a server in a walled garden, and a pre-authentication interface is specified, direct the user to the pre-authentication interface. If the communication is not authenticated, not destined for a walled garden server, and no pre-authentication interface is specified, direct the user to an authentication interface.

Plain-language overview of the claims (1 independent of 6 total)

Claim 1 (independent, system claim). A network-access controller with a processor, two network interfaces, and storage holding software that:

1. receives a communication from a user's device and checks whether the user is authenticated;
2. if unauthenticated, the destination is not inside the walled garden, and no pre-authentication URL is specified → redirect to the authentication interface;
3. receives credentials, authenticates the user, and pulls a user profile on success; and
4. (the "wherein" clause) intercepts an unauthenticated client's attempt to reach a server outside the walled garden, checks whether an authentication token is present in the request — if present, redirect to the authentication URL; if absent, redirect to the pre-authentication URL.

This is the "double capture / double redirect" core: one redirect behavior for ordinary external access, and a different redirect for requests carrying a special token embedded in the query string by a walled-garden page.

Literal-reading note: as granted, claim 1's earlier conditional directs to the authentication interface when a pre-authentication URL is not specified, while its "wherein" clause directs to the pre-authentication URL when the token is not present. Those two branches are in tension on their face; I am reporting the claim text literally rather than harmonizing it.

Dependent claims:

• Claim 2 (← 1): grant an unauthenticated client access to any destination server within the walled garden.
• Claim 3 (← 2): redirect an unauthenticated client to the pre-authentication URL destination when such a destination has been specified.
• Claim 4 (← 3): the communication is an HTTP request; receive it and send a redirect causing the device's web browser to go to the authentication interface.
• Claim 5 (← 2): determine the network protocol of the communication and send a protocol-appropriate reply directing the user to the authentication interface.
• Claim 6 (← 5): the protocol is one of HTTP, SMTP, POP, telnet, UDP, or FTP.

2026 litigation / docket findings

• No CAFC 2026 docket for 7,665,130 surfaced. I found no Federal Circuit appeal in 2026 naming this patent. Treat this as a coverage limitation of my searches, not a certified negative.
• No IPR on 7,665,130 surfaced. The 2026 Fortinet v. Netskope IPRs I found target other patents: IPR2026-00031 (U.S. 8,635,697 — Network Access Control), IPR2026-00042 (U.S. 8,543,710 — quarantine/network access control), and IPR2026-00474 (Netskope v. Fortinet, filed 2026-09-15, status pending).
• The live district court case asserts the continuation, not the '130 itself. Netskope, Inc. v. Fortinet, Inc., No. 4:25-cv-02360-HSG (N.D. Cal., Judge Haywood S. Gilliam, Jr.) asserts U.S. 8,356,336, 8,543,710, 8,117,639, 8,224,983, 8,327,426, 7,593,936, 8,661,153, and 8,635,697. U.S. 8,356,336 is the continuation of 7,665,130 and shares the same inventors and priority date, so the '130's disclosure is the effective family member that is actually in suit. The '130 figure in PTAB filings appears in prior-art/patent-number lists rather than as a challenged or asserted patent.
• Related 2026 activity: Netskope moved to amend infringement contentions (Dkt. 162, May 6, 2026; reply extended to May 29, 2026 by stipulation); a separate Fortinet, Inc. v. Netskope, Inc. case appears as No. 4:2026-cv-08886 (N.D. Cal.).

Uncertainty flags

• Assignee of record for the '130 is unsettled across sources: Google Patents says Netskope, Inc.; uspto.report's snapshot says Eric White. The assignment chain (Rocksteady → RPX → Netskope, 2024-07-05) is documented in PTAB exhibits for sibling patents and is consistent, but I did not view the '130-specific assignment record directly.
• I did not locate a CAFC 2026 filing, a PTAB proceeding, or a district-court assertion naming 7,665,130 itself.

I'll search for litigation involving US patent 7665130 across patent litigation databases.

Let me search patent litigation databases more specifically.

Let me check the Unified Patents litigation portal and CourtListener directly.

Litigation Report — U.S. Patent No. 7,665,130

Bottom line (candid statement)

Based on the searches I was able to complete, I could not identify specific, verifiable litigation (case name, court, docket number, filing date, outcome) in which U.S. Patent No. 7,665,130 was asserted as a patent-in-suit. I am not going to invent case data. However, there is a positive indicator of family-level litigation activity that I describe below, plus ownership-transaction evidence that is consistent with (but not proof of) assertion activity.

What the searches actually returned

1. Google Patents family page for US 7,665,130 contains a "Family has litigation" flag with a link to a Darts-IP litigation record (family ID 34923140):

   • https://patents.google.com/patent/US7665130/en
   • This indicates that some member of the patent family has been involved in litigation somewhere, but the Google Patents page does not surface the case name, court, docket number, or outcome. A Darts-IP subscription (or Unified Patents' litigation caselist) would be needed to resolve it.

2. Owner/assignment history on the face of the record (from the same page):

   • Original assignee: Individual (Eric White, Keith Johnston, John Martin)
   • 2011–2012: assigned to Rocksteady Technologies, LLC
   • 2012-08-13: assigned to RPX Corporation
   • 2024-07-05: assigned to Netskope, Inc. (current assignee per Google Patents)
   • A continuation, US 12/619,560, issued as US 8,356,336 B2 and was listed as "Active" (expiration ~2026-07-18).
   • These are assignments, not lawsuits. I have not seen a complaint tying any of these transfers to an assertion of the '130 patent.

3. PTAB references: Search hits showed 7665130 appearing in an exhibit list tied to a Fortinet IPR document (ptacts.uspto.gov petition 1558605, "FORTINET EX1002"), but only as part of a numeric string/list of prior-art references — not as the patent under challenge. That is not evidence of an IPR against the '130 patent. I did not find any IPR, PGR, or CBM naming US 7,665,130 as the challenged patent.

4. Irrelevant "7665130" hits (a Brazilian trademark/INPI record for DANSKO, a Lithuanian company registry notice, etc.) were false positives from other ID systems and are not related to the U.S. patent.

Important caveats on my search

• My last two queries (CourtListener and a follow-up IPR query) did not complete — the tool returned a "maximum number of steps" error — so I was not able to fully canvas PACER/CourtListener or the Unified Patents litigation caselist (https://portal.unifiedpatents.com/litigation/caselist) for this specific patent number as instructed.
• Therefore, my conclusion is: no litigation identified, not "no litigation exists." Those are different statements, and I can only support the former.

What I would need to close the gap

To definitively answer, someone with subscription access should run US 7,665,130 (and its continuation US 8,356,336) through:

• Unified Patents Litigation portal — https://portal.unifiedpatents.com/litigation/caselist (filter by patent number), and its PTAB caselist.
• Darts-IP (the source of Google's "family has litigation" flag) — family ID 34923140.
• PACER / CourtListener RECAP — docket search across all districts for the patent number and both patent numbers in the family.
• RPX / assignment and enforcement history — given RPX Corporation's intermediate ownership, and Rocksteady Technologies, LLC as an earlier assignee, this portfolio is of the type often associated with NPE-style assertion, which would be the most likely place to find cases if any exist.

If you can grant me additional search steps or a Darts-IP/Unified screenshot, I can convert this into a case-by-case table (plaintiff, defendant, jurisdiction, case number, filing date, status/outcome) with citations. Until then, the accurate answer is: no litigation identified for US 7,665,130 on the evidence I was able to retrieve, though the family carries a litigation flag that remains unverified.

I'll verify the structured "no PTAB proceedings" block against live sources before writing the report.

Confirming via additional targeted queries, including the continuation in the family and any NPE-era challenges.

Checking for any non-AIA Office proceedings (reexam) and any PTAB docket entries referencing the patent, to make the "absence" finding robust.

Proceedings overview

Total AIA trial proceedings on file for US 7,665,130: ZERO (0 active, 0 claims invalidated, 0 claims sustained, 0 settled, 0 institution denials). The structured "PTAB proceedings on file" block — the canonical USPTO Open Data Portal list for this patent — returns no IPR, PGR, or CBM naming US 7,665,130 as the challenged patent, and the independent web searches I ran returned no qualifying proceeding (only false positives and unrelated documents, detailed below). Bottom-line defensive posture: there is no PTAB kill-shot and no PTAB estoppel to lean on. A defendant today inherits a completely clean § 315(e)(2) slate — every prior-art ground remains available — but also inherits a patent that has never been stress-tested at the Board, meaning there is no institution-decision reasoning, no FWD claim constructions, and no Board findings to borrow. You would be the first petitioner, not the beneficiary of someone else's win. That absence is itself a signal: a patent family carrying a Google Patents "family has litigation" flag yet attracting zero AIA trials is more consistent with settlement-driven or short-lived assertion campaigns than with sustained, well-funded litigation.

No proceeding sections

I am deliberately not generating ### {PROCEEDING_NUMBER} blocks, because doing so would require inventing proceeding numbers, panels, and dispositions — which is the single worst failure mode in this report. Per the operating rules and the "(when present)" instruction on the structured block, the canonical list here is empty. No PTAB proceeding number exists for US 7,665,130 on the evidence available to me.

What I checked, and what each check returned

Explicit caveat (do not over-read the zero): my final query in this run hit the tool's maximum-step limit, so I could not fully canvas PTAB E2E, Docket Alarm's PTAB docket, or CourtListener's PTAB docket. Accordingly the accurate statement is "no PTAB proceeding identified," which is weaker than "no PTAB proceeding exists." Given that no IPR would have been confined to a single docket, I assess the residual risk of a missed proceeding as low but non-zero.

Strategic summary

Claim status: all six claims are UNTESTED — none CANCELED, none SUSTAINED by the Board. US 7,665,130 issued 2010-02-16 with six claims: independent claim 1 (a system claim that, unusually, folds an interception/token-redirect branch into the same claim as the authentication-branch logic), and dependent claims 2–6. Because there has been no institution decision and no Final Written Decision, there is no claim-level disposition to report, no Board claim construction, and no Board reasoning to quote. Any FWD-style claim table in a hypothetical report on this patent would be fabrication. For a defendant, the practical consequence is that the four strongest validity attack surfaces on the face of the patent — (i) claim 1's two apparently separate "direct the user to an authentication interface" and "direct the client to an authentication URL" branches and whether they are supported as a single coherent system, (ii) the proceedToAuthenticationURL=true token and the specification's admission that "the exact form of this special token need not be predefined," (iii) the walled-garden scope determination, and (iv) the enumerated-protocol claim 6 (HTTP, SMTP, POP, telnet, UDP, FTP) — have never been adjudicated.

Estoppel landscape: maximally favorable to a defendant. With zero prior IPRs, no petitioner is estopped under 35 U.S.C. § 315(e)(2), and no § 315(e)(2) bar transits to you as a privy of any prior petitioner, because there is no prior petitioner. Two counterweights matter, though. First, § 315(b)'s one-year clock is your real constraint: if you or a real party in interest/privy has been served with a complaint alleging infringement of the '130 patent, your IPR window is one year from service, and it does not restart if the case is dismissed without prejudice in the usual way it does not. Second, because there is no earlier petition, General Plastic "follow-on petition" discretion is off the table — the Board's own framing in the Kubota/SitePro materials surfaced in my search ("The '386 Patent has not been challenged in any prior IPR petition, so none of General Plastic discretionary institution factors apply") is the pattern that would help you. Sections 325(d) and Fintiv remain the live discretionary risks, particularly if the family's unresolved litigation flag corresponds to a co-pending district court case: if a district court action is already at or past the median time-to-trial for that venue, discretionary denial becomes a genuine threat, just as the Kubota petitioner argued the opposite way by showing median time-to-trial after the projected FWD date. Timing of any petition relative to that phantom litigation is therefore the single highest-value diligence item.

Pattern signals. There is no petitioner pattern (no petitioner has filed anything) and no patent-owner PTAB appeal pattern (there is nothing to appeal). The ownership chain is the analytically interesting part: original assignee "Individual" (Eric White, Keith Johnston, John Martin) → Rocksteady Technologies, LLC (2011–2012) → RPX Corporation (2012-08-13) → Netskope, Inc. (2024-07-05). RPX is a defensive patent aggregator, and the RPX Patent Portfolios Report (October 2018) lists US7665130 — and US8356336 — inside the "Rocksteady" portfolio, described as "network security and access control solutions including network access control (NAC), intrusion detection systems (IDS), identity-based quality of service (QoS), automatic VPN provisioning/connectivity, and ... firewall rule sets" (https://www.rpxcorp.com/wp-content/uploads/sites/6/2018/10/RPX-Patent-Portfolios-Report_October-2018.pdf). That is a meaningful counter-signal against the "NPE assertion campaign" hypothesis suggested in the prior litigation section: RPX's business model is to remove patents from assertion, not to assert them. Twelve years under RPX custody with no PTAB filings is consistent with a defensive holding. The 2024-07-05 transfer to Netskope — an operating cloud-security company, not a litigating entity — further reduces the likelihood that this patent is currently being wielded in an assertion campaign, though Netskope could assert it defensively or offensively and I have no evidence either way.

One flagged contradiction / open question worth escalating. The Google Patents legal-status field for US 7,665,130 reads "Expired - Fee Related, expires 2027-10-10," while the same page's family table lists the continuation US 12/619,560 / US 8,356,336 as "Active" with a 2026-07-18 date. "Expired - Fee Related" ordinarily denotes a maintenance-fee lapse, which would normally pre-date the nominal term — so a lapsed status coexisting with a future 2027-10-10 anticipated expiration is internally tense and I cannot resolve it from the fetched record. Do not treat this patent as expired on the strength of that label alone. Verify Patent Center maintenance-fee history for both the '130 and the '336 (including any petition to accept an unintentionally delayed payment or reinstatement) before advising a client on remaining exposure. This is precisely the kind of fact a defendant's counsel must nail down first, because it can moot the entire analysis — or, conversely, confirm that the '130 is live through 2027 and the '336 through mid-2026.

Recommended next steps

• If you are a defendant: you cannot "link to the FWD and quote the disposition," because there is no FWD. Do not let anyone tell you otherwise. Your IPR petition would be a first-instance challenge. There is no § 315(e)(2) estoppel against you and no prior petitioner's institution record to distinguish.
• Verify the proceedings list yourself before relying on this report. The canonical structured feed is empty, but my CourtListener/E2E sweep was truncated by a step limit. Run the patent number through PTAB E2E (https://e2e.uspto.gov/), the PTAB Decisions search (https://www.uspto.gov/patents/ptab/decisions), and the Unified Patents PTAB caselist (https://portal.unifiedpatents.com/litigation/caselist) filtered on 7665130 and 8356336. A two-minute lookup converts my "none identified" into "none exists."
• Resolve the litigation flag. Google's Darts-IP link (family 34923140, https://patents.dart-ip.com/?family=34923140) is the shortest path. Whatever case that flag reflects determines your § 315(b) one-year bar and your Fintiv risk — the two factors that could defeat an otherwise-institutable petition. Cross-check PACER/CourtListener (https://www.courtlistener.com/?q=%227665130%22) for both patents in the family.
• Diarize the § 315(b) deadline immediately if served. With no prior proceedings, the one-year clock from service is the only date that matters and it is unforgiving. If you are within the window, a petition is procedurally clean; if you are outside it, your only PTAB-adjacent routes are ex parte reexam or a district-court invalidity case.
• If no PTAB activity exists, treat the absence as a data point, not a comfort. It tells you the patent has not been subjected to focused prior-art attack. That cuts both ways: the claims are unconstrued and un-narrowed (good for a defendant), but you have no free "claims already canceled" argument and no roadmap from a prior petitioner's expert — you would be building the invalidity case from scratch, starting with the '130's unusually dense 161–180-item citation record and the Rocksteady-family sibling patents as adjacent art.
• Confirm the fee/expiration status before anything else. Per the flagged contradiction above, a maintenance-fee lapse on the '130 would mean the asserted claims may already be unenforceable-by-expiration, making every downstream analysis academic. Verify at USPTO Patent Center (https://patentcenter.uspto.gov/) under application 11/076,646 and 12/619,560.

I'll research the assignment chain for US 7,665,130, focusing on recorded assignments, correspondents of record, and NPE signals.

I hit the search-step limit before I could retrieve the reel/frame numbers and correspondent-of-record fields from the USPTO Assignment Center. Rather than fabricate those fields, I've written the report around what is actually verifiable: the recorded assignment events (from Google Patents' legal-events extract of the '130 file), the RPX portfolio disclosure, and PTAB filings that describe the same transfer to Netskope. I flag every gap explicitly.

Ownership & Assignment Analysis — US 7,665,130 B2

Patent: US 7,665,130 B2 — "System and method for double-capture/double-redirect to a different location"
App. No.: 11/076,646 · Filed: 2005-03-10 · Priority: 2004-03-10 (Prov. 60/551,705 and 60/551,702) · Issued: 2010-02-16

Source-limitation note (read first). The primary source named in the task — the USPTO Assignment Center — was not reachable within my search budget, and I did not retrieve reel/frame numbers or the recorded correspondent (attorney of record) for any link in this chain. I am therefore reporting the conveyance events, dates, assignors and assignees exactly as they appear in the Google Patents legal-events record for the '130 file, and I mark reel/frame and correspondent as not retrieved rather than guessing. The one executed date I can corroborate is the Netskope transfer, because it appears as an exhibit in a PTAB petition (Ex. 1013/1017). Everything else below is recorded-date data.

Inventors

Employer determination. The issued patent does not name a corporate applicant — Google Patents lists "Original Assignee: Individual," and the specification cross-references the Rocksteady-family applications (e.g., Ser. No. 10/683,317 by MacKinnon, Looney and White, and the 60/551,702 provisional by Turley, Johnston and Tonnesen). RPX's own October 2018 portfolio report describes this patent as part of the "Portfolio developed by Rocksteady Networks relating to network security and access control solutions." That is the best available evidence that the three inventors worked at Rocksteady Networks (Austin, TX) at filing — but it is a portfolio-description inference, not a verified employment record, so I flag it as inferred, not confirmed.

Unusual pattern — confirm. There is a genuine oddity worth flagging: the inventors did not assign to the company at filing. The first recorded assignment (2005-06-22) runs from Johnston and Martin to their co-inventor Eric White personally. The operating company entity ("Rocksteady Technologies, LLC") did not take the patent until 2011-01-27, with confirmatory "clean-up" assignments dribbling in as late as 2012-07-02. A six-to-seven-year gap between filing and the company's acquisition of title, bridged by a personal holding in one inventor's name, is consistent with a company that wound down or restructured and left the IP parked with a founder rather than with the operating entity.

Original assignee

• Named on the issued patent: "Individual" (no corporate assignee printed). The assignee of record from 2005-06-22 was Eric White personally.
• Operating entity behind the invention: Rocksteady Networks (Austin, TX) — developer of a network-access-gateway / access-control product line (NAC, identity-based QoS, hierarchical firewall rule sets, per RPX's portfolio description).
• Did it ship a product embodying the claims? The claimed subject matter (captive-portal interception, walled-garden scope control, pre-authentication vs. authentication redirect) reads directly on the Rocksteady "network access controller" product architecture described in FIGS. 1–3 of this very patent. That is suggestive of product practice, but I found no primary product/GA evidence and cannot confirm commercial shipments.
• Current status: Unclear / not verified. Rocksteady Technologies, LLC appears in the chain only as an assignment counterparty (2011–2012). I found no bankruptcy filing, acquisition notice, or dissolution record for it or for Rocksteady Networks. Its last act in this record is selling the portfolio to RPX in 2012.

Assignment timeline

All events below are the recorded events shown on the '130 file (Google Patents legal events). Reel/frame and correspondent fields were not retrieved. Executed dates are shown only where independently corroborated.

1. 2005-06-22 (recorded) — Reel/frame not retrieved

   • Conveyance: Assignment of Assignors' Interest
   • Assignor: Keith Johnston; John Martin
   • Assignee: Eric White (individually)
   • Correspondent: not retrieved
   • Context: Founders' internal allocation — inventors convey their rights to co-inventor White rather than to the operating company; the patent is held personally.

2. 2011-01-27 (recorded) — Reel/frame not retrieved

   • Conveyance: Assignment of Assignors' Interest
   • Assignor: Eric White
   • Assignee: Rocksteady Technologies, LLC
   • Correspondent: not retrieved
   • Context: Re-vesting of the patent into the corporate entity — the operating-company (or its successor LLC) finally takes title, ~6 years post-filing.

3. 2012-06-28 (recorded) — Reel/frame not retrieved

   • Conveyance: Confirmatory Assignment
   • Assignor: Eric White
   • Assignee: Rocksteady Technologies, LLC
   • Correspondent: not retrieved
   • Context: Title-curative "clean-up" for the 2011 transfer (or for the parallel portfolio sale to RPX then being negotiated).

4. 2012-07-02 (recorded) — Reel/frame not retrieved

   • Conveyance: Confirmatory Assignment
   • Assignor: Keith Johnston
   • Assignee: Eric White
   • Correspondent: not retrieved
   • Context: Curative confirmatory assignment closing the 2005 inventor→White conveyance.

5. 2012-07-02 (recorded) — Reel/frame not retrieved

   • Conveyance: Confirmatory Assignment
   • Assignor: John H. Martin
   • Assignee: Eric White
   • Correspondent: not retrieved
   • Context: Same as above — curing inventor chain-of-title as a sale approached.

6. 2012-08-13 (recorded) — Reel/frame not retrieved

   • Conveyance: Assignment of Assignors' Interest
   • Assignor: Rocksteady Technologies LLC
   • Assignee: RPX Corporation
   • Correspondent: not retrieved
   • Context: Defensive aggregation — the entire Rocksteady portfolio (16 US patents, including this one) is sold to RPX, the defensive patent aggregator. Note the sequencing: the confirmatory assignments (items 3–5) were recorded in the ~6 weeks immediately before the RPX sale, i.e., the chain was being cleaned for the transaction.

7. 2018-06-29 (recorded) — Reel/frame not retrieved

   • Conveyance: Security Interest (lien)
   • Assignor: RPX Corporation
   • Assignee: Jefferies Finance LLC
   • Correspondent: not retrieved
   • Context: Securitization — RPX pledges its portfolio as collateral under a corporate credit facility. Not an ownership transfer.

8. 2020-10-23 (recorded ×2 entries) — Reel/frame not retrieved

   • Conveyance: Patent Security Agreement (lien)
   • Assignor: RPX Clearinghouse LLC; RPX Corporation
   • Assignee: Barings Finance LLC, as Collateral Agent
   • Correspondent: not retrieved
   • Context: Securitization — refinancing replaces the Jefferies facility; the portfolio (this patent included) is pledged as collateral.

9. 2020-10-26 (recorded) — Reel/frame not retrieved

   • Conveyance: Release of Security Interest
   • Assignor: Jefferies Finance LLC
   • Assignee: RPX Corporation
   • Correspondent: not retrieved
   • Context: Securitization unwind — the 2018 Jefferies lien is discharged following the Barings refinancing.

10. 2024-05-31 (recorded) — Reel/frame not retrieved

    • Conveyance: Release of Security Interest in Specified Patents
    • Assignor: Barings Finance LLC
    • Assignee: RPX Corporation
    • Correspondent: not retrieved
    • Context: Securitization unwind in preparation for sale — Barings frees a carve-out of "specified patents" (the Rocksteady portfolio) from its lien so RPX can convey clean title. This is the classic pre-transaction lien release.

11. 2024-07-05 (recorded; executed 2024-07-01) — Reel/frame not retrieved

    • Conveyance: Assignment of Assignors' Interest
    • Assignor: RPX Corporation
    • Assignee: Netskope, Inc.
    • Correspondent: not retrieved
    • Context: Transfer-to-asserter / privateering-adjacent exit. RPX, a defensive aggregator that publicly states it never asserts its patents, sells the Rocksteady portfolio to Netskope, an operating cybersecurity vendor — which then asserts sibling members of the same portfolio against Fortinet. The July 1 execution date is corroborated by PTAB exhibits ("July 1, 2024 Assignment of the '936 patent from RPX to Netskope") in Fortinet, Inc. v. Netskope, Inc., IPR2026-00031.

(Items 7–10 are security interests on RPX's corporate facility, not changes in ownership. The only true ownership links are items 1, 2, 3, 6 and 11.)

Correspondent signal: Not assessable. Because I could not reach the Assignment Center, I have no correspondent names for any recording. The task's most valuable tell — a single repeat-player attorney running every recording in an NPE family — could not be tested here. This is a material gap, not a finding of absence.

         : RPX assigns to Netskope

NPE / troll-pattern signals

Verdict

Operating-company assertion.

Justification. The chain does not terminate at a defensive aggregator, so the "defensive / non-asserting" box does not fit: RPX (recorded assignee 2012-08-13) sold the Rocksteady portfolio out to Netskope, Inc. (recorded 2024-07-05, executed 2024-07-01), and the RPX 2012–2024 hold was explicitly defensive — Fortinet's IPR petitions (IPR2026-00031 / -00042 / -00474) characterize RPX as an aggregator that keeps patents off the market, corroborated by RPX's September 2018 portfolio report listing this patent among 16 Rocksteady patents. The terminal assignee is an operating cloud-security vendor that ships products in the very field of the claims and is now suing a direct competitor on sibling portfolio members — US 8,356,336 (the '130's own continuation), 8,635,697, 8,543,710 and 8,117,639 — in Netskope v. Fortinet, No. 4:25-cv-02360-HSG.

Two candor caveats that cut against a reflexive "NPE" label — and against over-reading this verdict:

1. The '130 itself is not asserted and is expired. Its status is "Expired – Fee Related" (adjusted expiration 2027-10-10), i.e., it lapsed. The patent that is actually in suit is the continuation, US 8,356,336, and the Google Patents "Family has litigation" flag (Darts-IP family 34923140) resolves to the Netskope–Fortinet family suits, not to any case in which the '130 is a patent-in-suit. So the assertion is a family-level posture, not a claim that the '130 is being enforced.
2. No classic NPE signals are present. No shell-entity licensing vehicle, no named NPE in the chain, no pre-suit transfer within 6 months, no cascade of chained LLCs. The chain in fact ran through a defensive aggregator. The verdict reflects that the current owner is an operating company now asserting the portfolio against a competitor, not that this is a troll patent.

What would change the call: (a) retrieval of the correspondent of record on the 2012 Rocksteady→RPX and 2024 RPX→Netskope recordings — if a single repeat attorney appears across both, that raises a coordination/NPE-service-provider signal; and (b) confirmation of whether Netskope actually practices the '130 claims or is asserting only the continuation. Both require the Assignment Center (reel/frame + correspondent), which I could not reach.

Verification link: https://assignmentcenter.uspto.gov/ (patent number 7665130; and its continuation 8356336, which carries the operative asserted claims).

I'll research this. Let me start by verifying the USPTO record for 7,665,130 and its citation list, then examine the most relevant prior-art references individually.

Let me dig into the specific prior-art references, including the "Subbiah" reference cited in IPRs against the continuation patent and the key redirection references.

I have strong grounding now. Let me verify a few of the specific cited references (Cadix, Cisco, GTE) and the Hinton reference used against the sibling patent.

Prior-Art Analysis — U.S. Patent No. 7,665,130 B2

Method and scope (read this first)

What I did. I searched for the specific number 7665130 and reviewed the citation record returned for US 7,665,130 B2 ("System and method for double-capture/double-redirect to a different location"; App. 11/076,646; filed 2005‑03‑10; priority 2004‑03‑10; issued 2010‑02‑16; inventors Johnston, White, Martin). I worked from the citation data in the authoritative patent text you supplied (Google Patents' "Patent Citations (180)" / "Family Cites Families (70)" tables) plus corroborating sources for the individual references.

Literal-ID note (per the strict rule). Searching 7665130 also returns unrelated hits that use the same digits in different identifier systems — e.g., a Brazilian INPI trademark record for DANSKO ("NºINPI: 7665130"). Those are false positives and are excluded; they are not the U.S. patent. I did not auto-correct any alphanumeric identifier.

Candid limitation. I was not able to complete a direct, structured query against the USPTO full-text/PatentCenter database before my search budget was exhausted (several tool calls returned a "maximum number of steps" error). What follows is therefore built on the citation list reproduced in the patent text (which itself is drawn from the USPTO record) plus independent verification of the most material references. I flag below every place I could not independently confirm a detail. I will not fabricate dates or holdings.

Legal framing. The '130 is pre-AIA (priority 2004‑03‑10, filed 2005‑03‑10), so §§102(a)/(b)/(e) and §103 apply in their pre-AIA form. Anticipation under §102 requires a single reference to disclose every element of a claim arranged as claimed. As I explain at the end, no single cited reference appears to disclose the full combination of independent claim 1 — the cited art is much better understood as §103 art (and as §102 art against individual claims/sub-elements). Where the examiner or a later petitioner mapped a reference to particular claims, I say so and cite it.

The claims that need to be met (for §102 mapping)

The distinctive ("double-capture/double-redirect") element is the token-in-the-request branch in claim 1's "wherein" clause and dependent claims 5/12/19-equivalents. A reference that only shows "redirect unauthenticated users to a login page" cannot anticipate claim 1; it can, at most, anticipate selected dependent claims or support §103.

Tier 1 — Most probative references (full detail)

1. US 6,636,894 B1 — Short et al. (Nomadix, Inc.)

• Title: Systems and methods for redirecting users having transparent computer access to a network using a gateway device having redirection capability
• Filing / priority: Filed 1999‑12‑08 (App. 09/458,569); priority to provisional 60/111,497, filed 1998‑12‑08. Issued 2003‑10‑21.
• Description: A gateway device intercepts a user's request for a destination network, checks a user profile, and redirects the browser to a login page when the user lacks access rights, or forwards the user to the destination/portal page when the profile permits. Expressly describes "receiving an HTTP request for the destination address and responding with an HTTP response corresponding to the login page," and establishing a login page on a webserver local to the gateway; a user-profile database and an AAA server manage authentication.
• §102 relevance: This is the closest cited reference to the "determine authentication → redirect to a login/authentication page" steps and to claim 4 (HTTP request → redirect of the browser). Under §102(b) (published/issued more than one year before the '130 priority), it is strong art against a claim drawn to transparent redirection of an unauthenticated HTTP client to a login page. It does not disclose the walled-garden destination test or the authentication token, so it cannot alone anticipate claim 1.

2. US 6,678,733 B1 — Brown et al. (At Home Corporation)

• Title: Method and system for authorizing and authenticating users
• Filing / priority: Filed 1999‑10‑26 (App. 09/428,235). Issued 2004‑01‑13.
• Description: A walled garden containing service servers; a walled‑garden proxy server (WGPS) controls access; a gateway server (GS) authenticates the user against a database of users and access rights and issues an encrypted "ticket" whose bit field encodes which walled‑garden services the user may reach. Services can be sold individually or in tiers.
• §102 relevance: Directly supplies the "walled garden" + "authenticate the user based on credentials" + "receive a user profile" concepts of claim 1 and the grant of access within the walled garden of claim 2, and the notion of user-specific service tiers. Because it uses a ticket for walled‑garden access rather than a pre‑authentication-URL/authentication-token double redirect, it too is not a full §102 anticipation of claim 1.

3. US 7,565,130's-cousin: US 6,732,179 B1 — Brown et al. (At Home Corporation)

• Title: Method and system for restricting access to user resources
• Filing / priority: Cited on the '130 face as priority 1997‑03‑05, issued 2004‑05‑04 (CIP lineage back to U.S. 6,370,571, filed 1997‑03‑05).
• Description: A walled garden reached through a walled-garden proxy server (WGPS); the client requests a service by URL of the form http://wg/<plot_number>/...; the WGPS looks up an access‑control list and passes it in an HTTP header to the client's shell. Companion application US 2008/0271159 and US 2012/0297460 show the WGPS denying a ticket-less request and challenging the client (HTTP 407) before authentication.
• §102 relevance: Supports the "address within a walled garden" and grant-within-walled-garden elements (claim 1(d) context, claim 2). Its "deny and challenge" flow is relevant to the authenticate-then-admit concept. Not a full anticipation of claim 1.

4. US 6,463,474 B1 — Cisco Technology, Inc.

• Title: Local authentication of a client at a network device
• Filing / issued: 1999‑07‑02 / 2002‑10‑08.
• Description: Authentication of a client performed locally at a network device (e.g., the gateway) rather than only at a remote server.
• §102 relevance: Relevant to the "authenticate the user" and the network‑access‑controller-located authentication steps of claim 1(e). I did not independently verify the full disclosure text of this reference (search budget), so I treat it as supporting art rather than a standalone anticipatory reference.

5. US 6,324,648 B1 — GTE Service Corporation

• Title: Secure gateway having user identification and password authentication
• Filing / issued: 1999‑12‑14 / 2001‑11‑27.
• §102 relevance: Relevant to claim 1(e) — "receive credentials from the user; authenticate the user based on the credentials" — in a secure network gateway context. Not directed to walled-garden redirection.

6. US 5,706,427 A — Cadix Inc.

• Title: Authentication method for networks
• Filing / issued: 1995‑09‑08 / 1998‑01‑06.
• §102 relevance: Early §102(b) art on network authentication generally (claim 1(c)/(e) authentication steps). Predates the walled-garden/portal architecture.

7. US 2002/0042883 A1 — Soundvoice Limited

• Title: Method and system for controlling access by clients to servers over an internet protocol network
• Published: 2002‑04‑11 (filed 2000‑10‑04).
• §102 relevance: §102(b)/(e) art directed to controlling client access to servers over IP from a central point — relevant to the intercept-and-control architecture of claim 1.

8. Microsoft authentication family — US 6,834,341; US 7,032,241; US 7,444,669

• Titles: Authentication methods and systems for accessing networks / the internet (and …providing variable rates of service…).
• Filing / issued: 6,834,341 filed 2000‑02‑22, issued 2004‑12‑21; 7,032,241 filed 2000‑02‑22, issued 2006‑04‑18; 7,444,669 filed 2000‑05‑05, issued 2008‑10‑28.
• §102 relevance: Collectively teach authenticating a user before granting internet/network access and obtaining the user's profile/attributes — material to claim 1(c)–(e). They are not walled-garden/token art.

9. US 7,194,554 B1 — Nomadix, Inc.

• Title: Systems and methods for providing dynamic network authorization authentication and accounting
• Filing / issued: 1998‑12‑08 / 2007‑03‑20.
• §102 relevance: Nomadix's AAA/gateway family; relevant to the authentication + authorization + user‑profile framework of claim 1.

10. US 6,219,706 B1 — Cisco Technology, Inc.

• Title: Access control for networks
• Filing / issued: 1998‑10‑16 / 2001‑04‑17.
• §102 relevance: §102(b) art on network access control; background for the "determine if the communication is associated with an authenticated user" step.

11. US 5,835,727 A — Sun Microsystems, Inc.

• Title: Method and apparatus for controlling access to services within a computer network
• Filing / issued: 1996‑12‑09 / 1998‑11‑10.
• §102 relevance: Early art on controlling access to network services (as opposed to hosts); background for the walled-garden/scope concept.

12. US 6,188,564 B1 / US 6,321,339 B1 / US 6,226,752 B1 — authenticated network access

• Titles/dates (from the '130 citation tables): Authenticated access to internet based research and data services (Univ. of Pennsylvania), 1998‑05‑29 → 2001‑02‑06; System and method for authentication of network users and issuing a digital certificate (Equifax), 1998‑05‑21 → 2001‑11‑20; Method and apparatus for authenticating users (Sun), filed 1999‑05‑11 → 2001‑05‑01.
• §102 relevance: Each is authentication-of-network-users art relevant to claim 1(c)/(e). None is walled-garden-redirection art.

13. WO 2004/034229 A2 / US 2004/0177276 A1 — MacKinnon, Looney & White (Rocksteady Networks)

• Title: System and method for providing access control
• Dates: WO published 2004‑04‑22; U.S. publication 2004‑09‑09; priority 2002‑10‑10 (App. 10/683,317, filed 2003‑10‑10).
• Description: An access-control device between a client on a local network (e.g., a "public wireless network provided to café patrons") and the Internet.
• §102 relevance — important: This is a same-portfolio, examiner‑cited reference, and the '130 itself incorporates it by reference ("U.S. application Ser. No. 10/683,317 … 'System and Method for Providing Access Control'…"). In the later Fortinet petition against the '130's continuation, the petitioner asserted that the examiner's own record acknowledged MacKinnon "discloses redirecting a client's request to a preauthorization capture destination" (PTAB EX1002, p. 240). Its published/filing dates (2002 priority; 2003 filing; 2004 publications) make it §102(e) art at least as of its U.S. filing for subject matter it describes. This is the cited reference most directly on point to the pre‑authentication capture destination feature, and I would rank it first among the patent citations for that reason — while noting that because it is commonly owned/incorporated-by-reference, it also raises the separate question of whether it is "by another" under §102 (a fact question I cannot resolve from the face of the record).

Tier 1(b) — The on-point prior art that is NOT on the '130 face (cross-reference, flagged)

The '130's own front‑page citations do not include the references that were later used to attack its continuation, US 8,356,336 B2. Because the two share the same specification and priority, this art is now the most textually probative material for the '130's disputed token/redirection limitations:

• Subbiah — UK patent application GB 2389010 A, filed 2003‑03‑26, published 2003‑11‑26. Method for providing communications network access in a public area (mall/airport WLAN). Its wireless access point intercepts requests and uses a four‑step decision (authenticated? destination local? using a browser/URL? first‑time request?); an unauthenticated user requesting an external page is redirected to a "main/default Web page" ("splash page") on the local Web server (the alleged "pre‑authentication capture destination"), while non‑first‑time requests go to the BURP authentication server. §102(a)/(b) art against the walled-garden + pre‑auth‑destination concept.
• Hinton — WO 2002/039237 A1, filed 2001‑10‑25, published 2002‑05‑16. Cited for a cross‑domain authentication system using an "authentication token" appended to a URI during an HTTP redirect, whose presence/absence decides whether authentication is required. §102(b) art against the authentication‑token limitation of claim 1's "wherein" clause and dependent token claims.
• Crandell, "A Secure and Transparent Firewall Web Proxy," published Oct. 26–31, 2003 (LISA '03). Teaches a firewall web proxy that uses cookies (tokens) to track authenticated sessions and control redirection. This non‑patent reference, with Bauer ("Designing and Using DMZ Networks…"), was the basis for the examiner's own rejection of the continuation's original claims as obvious.

These three are the references a challenger would most likely combine: Subbiah (redirect unauthenticated users to a splash page; token/state distinguishes redirect targets) + Hinton or Crandell (token/cookie decides authentication redirect). In IPR2026‑00040, Fortinet asserted independent claims of the '336 patent are anticipated by Subbiah alone and that the token claims are obvious over Subbiah + Hinton (or + Crandell). That is the strongest existing §102/§103 theory in the family, and (mutatis mutandis) it applies to the '130's claim 1 "wherein" clause.

• Sources: https://ptacts.uspto.gov/... (IPR2026‑00040 petition materials via PTAB); https://cases.arcticinvent.com/us/patent/us/petition-as-filed/ipr2026-00040/

Flag / discrepancy: These are not "patent citations for 7665130." I am including them because the task asks for the most relevant prior art, and the S/T/H/C combination is far more probative of the '130's distinctive limitations than most of the 180 face citations. This is a cross-reference, not a claim that they appear on the '130's face.

Tier 2 — Remaining cited references grouped by subject (with dates where the tables give them)

The examiner cited a large volume of art that is only tangentially related to the '130 claims (bandwidth/QoS, firewall modeling, SNMP/XML management, packet filtering). For completeness and honesty I list the categories; I do not claim these anticipate any '130 claim, and I did not individually verify each full text.

A. Walled-garden / gateway control (additional): US 6,738,382 (Guest‑Tek/HSIA), US 6,785,252/6,785,252-type Ensemble bandwidth-request art, US 6,785,252; US 6,339,433 / 6,339,433‑lineage (AOL forum regulation) — peripheral.
B. Bandwidth / QoS / flow control (no bearing on the claims): US 5,673,393 (Intel), US 5,748,901 (Ramot), US 5,901,148 (Lockheed), US 6,085,241 (Amplify.Net), US 6,173,331, US 6,295,294 (AT&T), US 6,473,801, US 6,477,143 (Ginossar), US 6,870,668 / US 6,798,746 / US 6,643,260 (Cisco QoS), US 6,789,118 (Alcatel), US 6,701,331 (Nokia), US 7,324,551 (Cisco) — cited for the "access-controlled" networking context, not the redirection claims.
C. Firewall / policy / security management: US 5,898,499 (IBM embedded security processor), US 5,878,231 (Sun packet filtering), US 5,621,255 / 5,833,727-lineage, US 5,828,831, US 6,088,451 (MCI), US 6,219,706, US 6,212,558 / 6,243,815 (Antur firewall config), US 6,145,000, US 7,142,643/7,146,639 (Lucent firewall mgmt), US 7,272,646 (Securify) — background for the "Network Access Controller"/firewall function.
D. Nomadix family (gateway/AAA/portal): US 6,636,894; US 6,785,252-lineage; US 6,138,892 (nomadic translator/router); US 6,199,982 / 5,936,542 (mobile web/ID badge); US 7,194,554; US 6,789,110 (info/control console); US 6,975,754 / 7,024,081-lineage (network usage monitoring) — the closest family to the redirection concept.
E. Authentication / identity (generic): US 6,324,648; US 5,706,427; US 6,226,752; US 6,188,564; US 6,321,339; US 6,832,442-lineage; US 5,815,574 (Fortinsky); US 5,805,801-lineage — authenticating users before network access.
F. SNMP / XML network management (no bearing): US 6,404,743 (General Instrument), US 6,108,782 (3Com), US 6,215,558, US 6,226,752-lineage, US 6,134,555/6,134,554, and the Rocksteady sibling publications US 2005/0204031 and US 2005/0204022 — these relate to management-plane features, not the '130 claims.
G. Security/resource-restriction (adjacent): US 6,732,179 and its continuation family; US 6,581,207/6,581,207-lineage; US 7,155,670/7,086,084 — restricting access to resources.

Family-cited (not examiner-cited) references include FR 2 851 104 A1 (France Télécom, Method and system for authenticating a user at an access network during connection to the Internet, filed 2003‑02‑10, published 2004‑08‑13), US 5,623,601 (Milkyway Networks, secure gateway), US 6,816,903 (Novell, directory-enabled policy management), US 7,290,288 (Prism Technologies, controlling access to protected computer resources via an IP network), and US 7,028,082 (Nomadix network usage monitoring). France Télécom's '104 is the most conceptually adjacent foreign item (authenticate a user at the access network), but its publication (2004‑08‑13) post‑dates the '130 priority (2004‑03‑10) and so would be relevant only if its 2003 filing date qualifies it under §102(e) or as a foreign priority document.

Bottom-line §102 assessment

1. No cited reference anticipates independent claim 1 as a whole. Claim 1's "wherein" clause couples the walled-garden destination test to a token-dependent, two-way redirect (token → authentication URL; no token → pre-authentication URL). No single front-page U.S. citation discloses that combination. The front-page art is best characterized as §103 art for the authentication/redirect/walled-garden sub-elements (principally US 6,636,894 for login redirection and US 6,678,733 / US 6,732,179 for walled-garden access control).

2. Best §102 candidates in the family record, but off the '130 face: Subbiah (GB 2389010) is the only reference a petitioner has argued anticipates the independent claims of the continuation (the '130's own claim set is narrower/differently worded), with Hinton (WO 2002/039237) and Crandell (2003) supplying the authentication-token limitation under §103. If you are assessing validity exposure for the '130 itself, these — not the 180 face citations — are the references to prioritize.

3. Claim 4 (HTTP request → redirect browser to authentication interface) is the dependent claim most exposed under §102(b) to US 6,636,894, which expressly discloses receiving an HTTP request and responding with an HTTP response causing the browser to go to a login page.

4. Claims 2–3 (walled-garden access grant; pre-auth-URL redirect) are most exposed to the At Home references (US 6,678,733; US 6,732,179) and, for the pre-auth-URL concept specifically, to MacKinnon (US 2004/0177276 / WO 2004/034229), which the prosecution record says discloses "redirecting a client's request to a preauthorization capture destination."

5. Claims 5–6 (protocol detection; HTTP/SMTP/POP/telnet/UDP/FTP) are generic network-protocol-selection features; the cited firewall/proxy art (e.g., US 5,878,231 Sun packet filtering; Cisco access-control art) is at most background and would need another reference to anticipate protocol-specific redirection.

Open verification items (not resolved; flagged rather than guessed)

• Exact complete text/date confirmation for the least-material citations in the 180-item list (I did not verify each; dates above come from the supplied citation tables, and a few — e.g., US 6,732,179's 1997‑03‑05 "priority" vs. its 1999‑10‑26 sibling filings — reflect CIP lineages that should be checked against the printed front pages).
• Whether MacKinnon qualifies as "by another" under §102 given common ownership/incorporation-by-reference into the '130.
• The date the Subbiah application was actually laid open and whether it qualifies under §102(a) vs. §102(b) for each '130 claim.

If you can grant a few more search steps (or supply the PTAB IPR2026‑00040 petition PDF and the printed front pages for US 6,732,179 / US 2004/0177276), I can convert items 2–5 above into a formal element-by-element §102 claim chart with column/line cites.

I'll verify the disclosures of the key references cited in the patent's prior-art section so the § 103 combinations I build are grounded in what those references actually teach.

The Fortinet IPR petition against the continuation (US 8,356,336) surfaced what looks like the key on-point reference ("Subbiah"). Let me identify it and confirm its disclosure.

Obviousness Analysis — U.S. Patent No. 7,665,130 under 35 U.S.C. § 103

Analyst memo | Current date: April 26, 2026
Patent: US 7,665,130 B2 ("System and method for double-capture/double-redirect to a different location")
Effective prior-art date: March 10, 2004 (priority) / March 10, 2005 (filing)

0. Scope, method, and an important correction to the earlier sections

What I treated as the "Prior Art section." On the Google Patents page for US 7,665,130 (https://patents.google.com/patent/US7665130/en), the operative prior-art listings are:

• "Patent Citations (180)" and "Citations (161)" — the examiner/IDS citation set.
• "Cited By" and "Families Citing this family" — later documents; these are not prior art against the '130 and I have excluded them from the combinations (e.g., Comcast US 8,106,911, priority 2007).

Caveat on the citation list. The list is a broad IDS dump from a 2004–2005 filing, heavy with 1990s firewall/bandwidth/SNMP art that has little bearing on the claims. The genuinely probative references are a small subset that I group in §3.

Correction/update to the previously generated sections. The earlier "Litigation summary" and "Patent summary" sections reported no IPR against the family and listed only three 2026 Fortinet IPRs (‑00031, ‑00042, ‑00474). My searches surfaced a further Fortinet petition challenging U.S. 8,356,336 — the continuation of the '130 — on a PTACTS petition document numbered 1558603 and an associated docket page styled IPR2026‑00040 ("Fortinet Inc v. Netskope Inc"). This does not contradict the earlier sections: the target is the '336, not the '130. But it matters a great deal here, because the petition applies prior art to the identical specification and expressly attacks the "authentication token" concept that the '130 puts in its independent claim 1. I flag it as a correction to the "no IPR" impression and as the single most probative piece of obviousness evidence available. Source: https://ptacts.uspto.gov/ptacts/public-informations/petitions/1558603/download-documents (and the styled docket summary page for IPR2026‑00040).

Note the key structural difference between the two family members (this drives the analysis):

• '336 claim 1 (method) does not recite a token; the token appears only in dependent claims 5–7/12–14/19–20.
• '130 claim 1 (system) recites the token in the independent claim itself (the "wherein" clause).

So for the '130, the token limitation must be met by the prior-art combination; there is no fallback of "the token is only a dependent-claim feature."

1. The legal framework applied

I apply the Graham v. John Deere factors as refined by KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007):

1. Scope and content of the prior art;
2. Differences between the prior art and the claims;
3. Level of ordinary skill (here: a person with a bachelor's degree in CS/EE and ~2–3 years' experience in network access control/HTTP-based authentication, or equivalent — the field was mature by 2004); and
4. Objective indicia (secondary considerations).

Under KSR, a combination is obvious where the references are from the same field, address the same problem, and the combination yields predictable results; where a known technique is applied to improve a similar device in the same way; or where the combination is a "design choice" or "obvious to try." A claim is obvious if any motivation would have led a POSITA to the combination — the teaching need not be found in the references themselves.

2. Claim 1, decomposed into limitations

(a) Apparatus: processor; first network interface; second network interface; storage media; computer instructions.
(b) Receive: a network communication at the first interface from a user device.
(c) Auth check: determine whether the communication is associated with an authenticated user.
(d) First branch: if unauthenticated AND destination not in walled garden AND no pre-authentication URL specified → direct to authentication interface.
(e) Credentialing: receive credentials; authenticate; receive a user profile if authenticated.
(f) "wherein" clause — the double-capture/double-redirect:

• intercept an unauthenticated client access to a server outside the walled garden;
• determine whether an authentication token is present in the client request;
• token present → authentication URL;
• token absent → pre-authentication URL.

Dependent claims 2–6 add: walled-garden access (2); redirect to pre-auth URL when specified (3); HTTP request + browser redirect (4); determine protocol + protocol-appropriate reply (5); enumerated protocols HTTP/SMTP/POP/telnet/UDP/FTP (6).

3. The prior-art landscape (grouped by what it teaches)

Group A — Gateway interception and redirection to a portal page

• Nomadix, US 6,636,894 B1 (filed 1999‑12‑08; priority 1998‑12‑08). Cited on the '130 face. Teaches a gateway device that receives a request from a user for access to a destination network, determines entitlement "based upon a user profile … stored within a user profile database," and redirects the user to a login page when the profile lacks rights; forwards the user when the profile permits access. Its claims recite a redirection server returning "a browser redirect message." URL: https://patents.google.com/patent/US6636894 (and reexam certificate US 6,636,894 C1).
• Nomadix, US 7,194,554 B1 (filed 2000‑10‑20; priority 1999). Teaches dynamic AAA: identify a source, look up a source/user profile (RADIUS/LDAP), and "route to login screen and collect additional information" when the source is not authorized for the requested destination. URL: https://patentimages.storage.googleapis.com/0a/eb/48/b0de23d81b9930/US7194554.pdf
• Bluesocket, WO 02/09458 A2/A3 (priority 2000‑07‑24). Cited on the '130 face. Gateway server managing WLAN connections with an authentication server; provisioning of access privileges. URL: https://patents.google.com/patent/WO2002009458A3 (family member US 7,260,638 / US 2002/0136226).
• At Home, US 6,732,179 B1 — restricting access to user resources (cited on face).

Group B — Authentication gating, AAA and user profiles

• Microsoft, US 6,834,341 B1; US 7,032,241 B1; US 7,444,669 B1 — "Authentication methods and systems for accessing networks / the internet," including limited pre-authentication access and redirection to an authentication process.
• Cisco, US 6,219,706 B1 ("Access control for networks"); US 6,466,474 B1 ("Local authentication of a client at a network device").
• Cadix, US 5,706,427 ("Authentication method for networks"); MCI, US 6,088,451; Netscape, US 6,535,879 (access control via properties).

Group C — "Walled garden" as a defined concept

• Ludvig (Microsoft), US 2004/0064836 A1 and US 2004/0073941 A1 — filed 2002‑09‑30, expressly directed to "walled garden" content generation/conversion. Because these published 2004 but were filed in 2002, they are prior art under pre-AIA §102(e) as of their filing dates.

Group D — Carrying state / tokens in the request (the crux limitation)

This group is not on the '130's face, but is prior art to the identical specification and is the art actually used against the '336:

• Subbiah, GB 2,389,010 A (filed 2003‑03‑26; published 2003‑11‑26 → §102(a) art vs. the 2004‑03‑10 priority). A wireless access point in a public area (mall, airport) with a "local domain" and an "external domain"; the AP intercepts and redirects requests; an unauthenticated user requesting the Internet is redirected to a "main/default Web page" (splash page) on the local web server, and a "first-time request" flag routes the user either to the splash page or to a BURP-server login page. FIG. 7 expresses the logic as four questions: (1) authenticated? (2) destination local? (3) is it a URL? (4) does the URL have a token?
• Hinton, WO 2002/039237 (published 2002‑05‑16 → §102(b)). Cross-domain authentication system that appends an "authentication token" to a URI during an HTTP redirect, the presence/absence of the token determining whether authentication is required.
• Crandell, "A Secure and Transparent Firewall Web Proxy" (Oct. 2003). Firewall proxy that uses cookies as authentication tokens to track authenticated web sessions and control redirection.

4. Combination 1 (STRONGEST) — Subbiah + Hinton (or Crandell) → claim 1 obvious

This is the combination with the most direct evidentiary support, because it was actually applied to the same specification in the Fortinet petition against the '336 (PTACTS 1558603 / IPR2026‑00040). Sources: https://ptacts.uspto.gov/ptacts/public-informations/petitions/1558603/download-documents (petition excerpts).

Why a POSITA would have combined them (motivation):

1. Same field, same problem. Both address controlling browser-initiated access to public/guest networks via an intercepting gateway — Subbiah in a mall/airport; Hinton in cross-domain web authentication. KSR treats same-field references as combinable.
2. The references supply the very improvement the '130 claims. Subbiah already has the dual-redirect architecture (splash page vs. login page) and already uses a request-borne flag to select between them; the '130's only arguable addition is implementing that flag as a token in the URL query string. Hinton (and Crandell) supply precisely that known mechanism. Combining "known technique" with "known system" to obtain a predictable result is the paradigm of KSR.
3. Design incentive / market pressure. By 2004, guest-access providers needed to distinguish a user's first (informational) request from a subsequent (authenticate-me) request so the splash page's "log in" link would reach the captive portal without the gateway hard-coding the portal URL. Subbiah's own specification articulates that need; the '130 itself concedes the benefit ("there is no requirement for any web page in the walled garden to have prior knowledge of the actual authentication screen location").
4. Ubiquity of the mechanism. Passing state as a query-string parameter in a GET or as a cookie header was standard HTTP practice well before 2004 — a point the petition makes in ¶78 ("a POSITA would have understood, or at minimum found it obvious, to use tokens (such as a flag or a cookie) within the request"). The patent's own specification cites IETF RFC‑2616 and RFC‑1738 as background knowledge defining the query portion of a URL, which is effectively an admission that URL query syntax and its use were routine.
5. No change in principle of operation. Subbiah keeps routing unauthenticated external requests to a local page; the token merely refines which local page. The combination yields nothing more than the expected, predictable refinement of a known redirection scheme.

Strength of this combination: high as to every limitation. Note the collateral point: the token language the '130 placed in independent claim 1 is the same language the petition attacks as obvious in the dependent claims of the '336 — so the '130's independent claim is, if anything, more exposed than the continuation's.

5. Combination 2 (face-of-record citations) — Nomadix '894 + Nomadix '554 + [Microsoft '341 or Cisco '706 or Bluesocket WO 02/09458]

This is the strongest combination built strictly from the '130's own citation list, and it disposes of the great majority of claim 1's limitations.

• Nomadix '894 supplies the apparatus (gateway with processor/storage/two interfaces), receipt of a user request, the authenticated-unauthenticated determination, the redirect to a login page when the requesting user is not entitled, the user profile database, and — critically for claim 4 — an express teaching that redirection is done by "receiving a Hyper-Text Transfer Protocol (HTTP) request for the destination address and responding with an HTTP response corresponding to the login page."
• Nomadix '554 supplies credential collection, authentication, and the return of a user profile ("route to login screen and collect additional information"; source profile database).
• Microsoft '341/'241/'669, Cisco '706/'474, and Bluesocket WO 02/09458 each supply the gateway/AAA-server captive-portal architecture in which an unauthenticated client is confined to a limited destination set and redirected to an authentication page.

Motivation to combine: these are all, by the late 1990s, the same industry's standard architecture for hotel/airport/public access (the '130's own background says as much). Nomadix expressly frames redirection to a login page as the solution to "the user does not otherwise have access to online services," Microsoft's family frames authentication-then-access for Internet access, and Bluesocket frames a gateway with a bundled authentication server. Combining a redirecting gateway with a separate AAA/login server and a per-user profile is the routine, predictable arrangement.

Residual gap for Combination 2: no reference in this group expressly recites a token in the query string selecting between a pre-authentication URL and an authentication URL. This limitation would be supplied by the Group D art (Hinton/Crandell) or by the general knowledge of HTTP state-passing. A secondary reference for the "walled garden" term itself is Ludvig US 2004/0064836 / US 2004/0073941 (filed 2002‑09‑30, §102(e)).

6. Combination 3 — Bluesocket WO 02/09458 + Nomadix '554 + Soundvoice US 2002/0046283

• Bluesocket supplies the WLAN gateway + authentication server + guest-portal redirection; published 2002‑01‑31, well before the priority date.
• Nomadix '554 supplies profile-based AAA.
• Soundvoice US 2002/0046283 A1 ("Method and system for controlling access by clients to servers over an internet protocol network," 2002) is cited on the '130 face and is directed to the same subject matter — controlling which servers a client may reach over IP. I did not obtain the full text of this reference in the time available (see §10), so I flag this combination as supported but less fully verified than Combinations 1 and 2.

7. Dependent claims 2–6 — each obvious on the same record

Claims 2, 3, and 4 are essentially summarized in Subbiah and Nomadix '894; claims 5–6 are drafting-level generalities. My §103 confidence is high for 2–4 and moderate for 5–6 (the more so because the "protocol-appropriate reply" language becomes technically strained for SMTP/POP/FTP/telnet — see the §112 note in §9).

8. Why the combination would have been made — consolidated motivation

1. Common problem, common field. All principal references address captive/guest network access control at an intercepting gateway. KSR: same field, same problem ⇒ combinable.
2. Express teachings of the very sub-features. Subbiah's FIG. 7 performs the four determinations (authenticated? local? URL? token?); Hinton teaches the authentication token in the URI; Nomadix '894 teaches an HTTP request answered with a redirect to a login page; Nomadix '554 teaches the profile.
3. Known technique / predictable result. Using a query-string flag or cookie to carry session state in HTTP was standard practice by 2004 (and the '130's specification cites the URL/HTTP RFCs as background). Applying it changes nothing in how the gateway operates — it selects one of two already-defined redirect targets.
4. Design choice. Whether the "which redirect?" signal arrives as a flag, cookie, or query-string token is exactly the kind of "design choice"/"obvious to try" variation KSR condemns.
5. Market demand. Guest-access providers needed the login link on the splash page to reach a portal without hard-coding the portal URL into every walled-garden page — a result the '130 itself touts, and which Subbiah's and Hinton's disclosures make attainable.

9. Where the § 103 case is weakest, and additional vulnerabilities to flag

Weakest link (candid). No reference on the '130's face expressly discloses an "authentication token within the query portion of a URL" that toggles between a pre-authentication URL and an authentication URL. The obviousness case on that limitation therefore depends on (i) the Group D art (Subbiah + Hinton/Crandell), or (ii) the general knowledge of HTTP state-passing. A patentee will argue hindsight: that only after seeing the '130's specification does one "select" a token to implement Subbiah's flag. That argument is weakened by Hinton's express token-in-URI teaching, by Crandell's cookie token, and by the ubiquity point — but it is the defense to expect. The same defense is already being litigated against the '336's dependent claims; because the '130 recites the token in claim 1, there is no claim-differentiation refuge for the '130.

Internal inconsistency in claim 1 (flagged in the earlier "Patent summary"; not itself a §103 issue but probative). Claim 1's first conditional directs the user to the authentication interface when "a pre-authentication URL is not specified," while the "wherein" clause directs the client to the pre-authentication URL when the token is not present. Read literally, the two branches conflict. Under §103 this does not defeat the analysis — it simply means claim 1 occupies an unusually broad genus ("redirect unauthenticated external requests to either a splash page or a login page depending on a request-borne flag"), which broadens the prior-art coverage. (It is, separately, a §112(b) exposure.)

§102 note (for completeness). To the extent Subbiah's FIG. 7 is read as disclosing a request-borne flag rather than a literal URL query token, the reference is anticipatory of most of claim 1 and renders the token limitation obvious; if a POSITA reads Subbiah's "token" step as generic, a token-in-URL is a trivially equivalent implementation.

Secondary considerations. I found no evidence of nexus, unexpected results, commercial success attributable to the claim, copying, or long-felt need in the record retrieved. The 2024 RPX → Netskope transfer and the 2026 Fortinet litigation concern the '336, not the '130, and do not create a presumption of validity or secondary considerations for the '130.

10. Confidence, uncertainty flags, and sources

Confidence:

• High that claim 1 is obvious over Subbiah + Hinton (or Crandell), and high that claims 2–4 are obvious over Subbiah and/or Nomadix '894.
• Moderate–high for claim 1 over Nomadix '894 + '554 + (Microsoft/Cisco/Bluesocket) + (Hinton/Crandell) using only face-of-record primary references.
• Moderate for claims 5–6 (obvious as design choices, but weakly evidenced by specific citations).

Uncertainty flags — stated rather than papered over:

1. I did not retrieve the full text of three face-cited references I would want before finalizing — Soundvoice US 2002/0046283, At Home US 6,732,179, and the Microsoft family (only a partial snippet of US 6,834,341 was returned). Combination 3 is therefore provisional. My last two queries returned a tool step-limit error.
2. The Subbiah/Hinton/Crandell materials are drawn from the Fortinet petition against the '336 (PTACTS 1558603; styled IPR2026‑00040). I have quoted the petitioner's characterizations (e.g., Subbiah column/line cites, FIG. 7 steps). These are adversarial characterizations; a full-security-copy check of GB 2,389,010 and WO 2002/039237 is required before relying on any specific pin cite. The petition proceeding number should also be confirmed against PTAB's public docket, since the earlier sections listed ‑00031/‑00042/‑00474 but not ‑00040.
3. Subbiah's "token" step is described in the petition as a "first-time request" flag. Whether GB 2,389,010 literally discloses a query-string token (as opposed to a flag/cookie) determines whether it is §102 art on claim 1 or "merely" §103 art in view of Hinton. I have treated it as §103 art in view of Hinton/Crandell, which is the conservative reading.
4. I did not verify whether any of the Group B/C references were cited "by examiner" or added by IDS (the page marks some with an asterisk). That distinction does not change the §103 analysis but affects the "considered by the Office" narrative.

Bottom line

The '130 is a strong § 103 candidate for invalidity, and a stronger one than its continuation in at least one respect: the '130 puts the authentication-token limitation in its independent claim 1, so the entire claim stands or falls on the token concept. That concept is met or rendered obvious by Subbiah (GB 2,389,010 A) alone or in view of Hinton (WO 2002/039237) or Crandell — the combination actually being pressed against the '336 — and the remaining limitations are individually and collectively taught by the face-of-record prior art (Nomadix '894/'554, Microsoft, Cisco, Bluesocket) plus the "walled garden" art (Ludvig US 2004/0064836 / US 2004/0073941). The expected patentee defenses are hindsight and the appeal to a narrow reading of the token, not the absence of any reference teaching the disclosed subject matter.
