US 8359029

I'll verify the details with targeted searches, then summarize.

Scope and verification note

I searched for the specific identifier 8359029 / US 8,359,029 and did not auto-correct or substitute any similar number. Two important caveats up front:

• No CAFC 2026 docket involving US 8,359,029 was found. The prominent 2026 Federal Circuit activity in the Lemko portfolio is Lemko Corp. v. Microsoft Corporation, No. 2024-2336 (Fed. Cir.), which is an appeal from IPR2023-00531 and concerns U.S. Patent No. 7,855,988 (the "’988 patent"), not the ’029 patent. On April 10, 2026 the court issued a Rule 36 per curiam judgment AFFIRMED (Hughes, Stoll, JJ., and Seeborg, C.J.D.), backing the PTAB's invalidity finding. (opinion PDF)
• The USPTO/Google Patents record identifies one live district-court matter tied to this patent: Texas Eastern District Court case 2:25-cv-00305 (Lemko Corp. v. AT&T Inc., filed 2025-03-17, J. Gilstrap). Separately, IPR2025-01142 (Microsoft/AT&T v. Lemko) challenges the ’990 patent (U.S. 8,310,990), a different patent.

Abstract (verbatim)

"A non-transitory computer readable storage medium of a first distributed management architecture (DMA) system includes a first home location register (HLR) that stores information associated with one or more mobile subscribers that are registered with the first DMA system. The non-transitory computer readable storage medium includes a community location register (CLR) associated with a second DMA system. The CLR stores information associated with a second HLR of the second DMA system, and the second HLR stores information associated with one or more mobile subscribers that are registered with the second DMA system. The non-transitory computer readable storage medium includes instructions that, when executed by a processor, cause the processor to initiate connection of a call from a first mobile subscriber to a second mobile subscriber via the first DMA system and the second DMA system when the second mobile subscriber is registered with the second DMA system."

Plain-language overview of the independent claims

⚠️ Uncertainty flag: the patent text I retrieved (Google Patents full-text rendering) reproduces the abstract, specification, and figures list but does not include the actual numbered claims. The descriptions below are reconstructed from the patent's summary-of-invention passages, which in this document track the claim set closely. The exact claim numbers and exact claim wording are not verified here.

The patent appears to be directed to a small, self-contained "distributed mobile architecture" (DMA) box that absorbs the functions of an MSC and a BSC, with DMAs linked peer-to-peer over an IP network, and with location data replicated so any DMA can find and route to subscribers homed on another DMA.

The independent claims appear to fall into these groups:

1. Computer-readable-medium claim (first DMA system). The core concept: a storage medium in a first DMA holds (a) a first HLR listing subscribers registered with that DMA, and (b) a CLR that mirrors the HLR of a second DMA. Instructions cause the processor to set up a call from one mobile subscriber to another through the first and second DMA when the called subscriber is registered with the second DMA. This is the plain-language core of the abstract.

2. Computer-readable-medium claim (look-up/routing order). A call from a first subscriber to a second subscriber arrives at a first DMA of a DMA network. The instructions first check the first HLR to see whether the second subscriber is local; if not, the instructions check the second CLR (which holds the second DMA's HLR information) to determine whether the callee is registered with the second DMA. In short: check home first, then consult the replicated neighbor register.

3. Method claim (roaming / location-update relay). A second DMA receives registration information about a mobile subscriber while that subscriber is physically inside the coverage area of a third DMA. When a first DMA sends a location-update request, the second DMA relays a second location-update request to the third DMA; the third DMA returns a destination IP address for the subscriber; the second DMA passes it back to the first DMA; the call is then connected first-DMA-to-third-DMA over a peer-to-peer IP connection using the source IP (first DMA) and destination IP (subscriber). This is the essential "roaming subscriber is found via a chain of DMAs, and media then flows directly DMA-to-DMA" concept.

4. Authentication, authorization, and accounting (AAA) module claim. An AAA module of a first DMA contains its own HLR, plus a first CLR that replicates that HLR into a second DMA, plus a second CLR holding information about subscribers registered with the second DMA (and optionally a third CLR for a third DMA, and a VLR for roaming subscribers temporarily registered locally). Dependent-type features recite the register fields: IMSI, ESN, MDN, location indicator, TLDN, registration indicator, timer, and MSC / ISDN / VoIP preference indicators.

5. Method of communication (single-DMA call). Register a first subscriber in the DMA's HLR; register a second subscriber in the same HLR; receive a call from the first to the second; locate both subscribers' data in the HLR; and connect the call locally within the one DMA using local IP addresses. Essentially intra-box switching with no external core network.

6. Method of establishing communication via a DMA network (cross-DMA call). Receive a call at a first DMA directed to a second subscriber and locate that subscriber's data in a CLR at the first DMA that holds information about subscribers registered with the second DMA — i.e., resolving a non-local callee using the replicated register before completing the call.

7. Method of establishing a call (location-update receipt). The mirror-image of group 3, framed from the receiving side: a second DMA receives a location-update request relating to a second subscriber, where the request was sent from a first DMA.

8. Apparatus claim (distributed mobile architecture). A DMA device comprising a processor, a computer-readable medium accessible to the processor, and an embedded AAA module; the AAA module includes an HLR of locally registered subscribers and a CLR containing information about the HLR of another DMA.

9. System claim (multi-DMA network). A system with a first DMA, a second DMA coupled to the first via an IP network, and a third DMA likewise coupled; the first DMA contains an HLR, a second CLR associated with the second DMA, and a third CLR associated with the third DMA.

Technical gist across all of them: the invention moves the location-register intelligence (HLR/VLR) and the switching/control intelligence (MSC/BSC) into a portable, low-cost node, replicates neighbor-DMA register data into "community location registers," and routes calls between nodes over IP rather than through a centralized hub — the stated motivation being the ~$2M cost and 10,000-subscriber viability threshold of a conventional MSC/BSC/HLR system in rural deployments.

Legal / portfolio context (search-derived)

• IPR challenges: Microsoft (with Affirmed Networks) filed IPRs against Lemko patents in Feb. 2023 — IPR2023-00529 (’414), IPR2023-00530, and IPR2023-00531 (’988). Microsoft's petition in IPR2023-00530 was denied institution (Paper 8, Sept. 25, 2023). In IPR2023-00531 the Board found claims anticipated by U.S. Pub. 2007/0021120 A1 (Flore); Lemko appealed (No. 24-2336), and the Federal Circuit issued a Rule 36 affirmance on April 10, 2026. None of these rulings is on US 8,359,029.
• IPR2025-01142 (Microsoft Corp. and AT&T Services, Inc. v. Lemko Corp.) challenges U.S. Patent No. 8,310,990, not the ’029 patent; Lemko filed a discretionary-denial request citing the parallel E.D. Tex. action filed March 17, 2025.
• Asserted-patent set in the AT&T action as quoted from a complaint exhibit: "the ’230, ’066, ’322, ’990, ’667, ’029, and ’020 Patents." The ’029 entry is consistent with US 8,359,029 appearing among the asserted patents in 2:25-cv-00305, but I did not independently verify each cited short number to its full patent number.
• Ownership history matters here: Motorola Solutions recorded a covenant not to sue against Lemko in 2012 following the N.D. Ill. case Motorola, Inc. v. Lemko Corp., No. 08 C 5427 (opinion Jan. 10, 2012, denying summary judgment on Motorola's patent-ownership and trade-secret claims). A 2025 patent security agreement in favor of Piccadilly Patent Funding LLC is also of record. Current assignee listed by Google Patents remains Lemko Corp.

Where I lack authoritative information

1. Exact claim text and claim numbering for US 8,359,029 — not present in the retrieved sources. My claim overview is inferred from the specification's summary passages and should be verified against the USPTO PatentCenter/Patent Public Search claims.
2. Any CAFC 2026 docket naming US 8,359,029 specifically — none found. The April 10, 2026 Rule 36 judgment concerns IPR2023-00531 and the ’988 patent.
3. Whether every short ID in the RPX-quoted "Asserted Patents" list maps 1:1 to the full numbers I would expect — not independently verified in this session.
4. PTAB/litigation outcome for the ’029 patent itself — I found no IPR instituted against US 8,359,029 in the material retrieved.

I'll research litigation involving US Patent 8,359,029 (Lemko Corp., "System, method, and device for providing communications using a distributed mobile architecture").

Let me dig deeper into the specific cases and check for IPRs and the 2026 Microsoft case.

Let me verify the 2026 Microsoft case and check for any IPR directed at the '029 patent specifically.

Litigation Involving U.S. Patent No. 8,359,029

Verification caveat up front: I searched litigation aggregators (Unified Patents portal, Docket Alarm, Justia Dockets/Ex Parte, RPX Insight, Mondaq, Law360). I found one district-court case that asserts the '029 patent by name. I could not confirm any PTAB proceeding, ITC investigation, or appellate case specifically on the '029 patent. Where I could not verify something, I say so explicitly below rather than extrapolating.

1. Lemko Corporation v. AT&T Inc., et al. — the '029 patent IS asserted

Asserted patents in this case (seven): 7,840,230; 7,979,066; 8,224,322; 8,310,990; 8,340,667; 8,359,029; and 9,198,020.

How the '029 patent is asserted: Count XI of the complaint is "Direct Infringement of the '029 Patent." Lemko alleges AT&T directly infringes at least exemplary Claim 1 under § 271(a), and pleads, in the alternative, direct infringement by acting as "final assembler" and by directing/controlling the accused systems. Claim 1 (quoted in the complaint) recites a non-transitory computer-readable storage medium of a first DMA system comprising an AAA module with a first HLR and a first CLR, plus instructions to initiate connection of a call between first and second mobile subscribers via the first and second DMA systems.

Note the parties, case number, and jurisdiction are corroborated by the Google Patents "Family has litigation" entry for US 8,359,029 itself, which links to https://portal.unifiedpatents.com/litigation/Texas%20Eastern%20District%20Court/case/2%3A25-cv-00305.

2. Related Lemko litigation that does NOT assert the '029 patent

For completeness — and to prevent false positives — the following Lemko matters are not '029 cases:

• Lemko Corp. v. Microsoft Corp. and Affirmed Networks, Inc., No. 3:22-cv-00363-L-BT (N.D. Tex.) — filed February 2022. The patents asserted there are reported as 7,548,763; 7,653,414; 7,855,988; 8,107,409; 8,688,111; 9,191,980; 9,332,478; and 9,755,931. The '029 patent is not in that list. Reported status: still in the pleadings stage (serial motions to dismiss).
• Lemko Corp. v. Microsoft Corp., No. 3:26-cv-01876 (N.D. Tex.) — an aggregator entry shows a filing dated 06/05/26, status "Open." I could not verify which patents are asserted, and the listed date is inconsistent with the current date of April 26, 2026. Treat this entry as unverified.
• Motorola Solutions covenant not to sue (2012) — USPTO assignment records show Lemko granted Motorola Solutions a "COVENANT NOT TO SUE" (recorded 2012-02-21) covering at least the '988 patent. This is an agreement, not litigation.

3. PTAB (IPR) proceedings — none identified on the '029 patent

I found several Lemko IPRs, but none on the '029 patent:

• IPR2023-00529 (U.S. Patent 7,653,414) — Microsoft Corp. and Affirmed Networks, Inc. v. Lemko Corp.
• IPR2023-00531 (U.S. Patent 7,855,988) — same parties; Final Written Decision Sept. 10, 2024 (claims held unpatentable over Flore).
• IPR2023-00530 (U.S. Patent 7,548,763) — institution denied (Sept. 25, 2023).
• IPR2025-01142 (U.S. Patent 8,310,990) — Petitioner AT&T; Lemko filed a Patent Owner Preliminary Response arguing discretionary denial (Fintiv/§ 325(d)); the Decision on Institution deadline referenced in that filing was January 8, 2026.

The '990 IPR is a companion to the same E.D. Tex. action, but the '990 patent is a different patent from the '029 patent. Despite targeted searches, I did not locate an IPR petition challenging the '029 patent. A companion petition on the '029 patent may exist (e.g., a possible IPR2025-01143), but I could not verify it and therefore do not assert it.

4. Appellate — none identified on the '029 patent

• Lemko Corp. v. Microsoft Corp., Affirmed Networks, Inc., No. 2024-2336 (Fed. Cir.) — appeal from IPR2023-00531 (the 7,855,988 patent). Affirmed under Fed. Cir. R. 36 by per curiam judgment entered April 10, 2026 (Hughes, Stoll, JJ., and Seeborg, C.D.J.). This concerns the '988 patent, not the '029 patent.

Bottom line

• Known litigation involving US 8,359,029: exactly one case — Lemko Corporation v. AT&T Inc., et al., No. 2:25-cv-00305 (E.D. Tex., filed March 17, 2025, Judge Gilstrap), pending/Open.
• No PTAB, ITC, or appellate proceeding specific to the '029 patent was identified.
• The '029 patent is also referenced as part of the "Asserted Patents" and patent-marking label in that E.D. Tex. complaint, but the only pleading count naming it is Count XI (direct infringement, § 271(a), of at least Claim 1).

If you need PACER-verified docket-level confirmation of the current status in 2:25-cv-00305 (including whether an IPR on the '029 patent has since been filed), that would require a live PACER/PTAB pull, which I could not complete within this session.

Proceedings overview

Total AIA trial proceedings on U.S. Patent No. 8,359,029: zero. The USPTO Open Data Portal (ODP) structured record — the canonical PTAB proceedings list supplied in this prompt — returns no IPR, PGR, or CBM naming the '029 patent, and independent web searches of the PTAB docket (PTACTS), Docket Alarm, IPVerse/GreyB, and Unified Patents litigation data surfaced no petition challenged to date on the '029 patent. Bottom line for a defendant: the '029 patent is completely untested at the Board — there is no FWD to lean on, no canceled claim to point to, and no § 315(e)(2) estoppel to exploit. Nobody has yet done the work of killing it.

A caveat that goes the other way as well: an unchallenged patent is not a strong patent, it is an unknown one. The absence of PTAB activity is a data point, not a safe harbor.

Proceedings on U.S. 8,359,029

None. There is no proceeding to describe. I will not manufacture a proceeding number; if the ODP list is eventually populated (e.g., a companion petition to the AT&T E.D. Tex. campaign), the entry should appear at the PTACTS docket for Tech Center 2400 and at https://ptacts.uspto.gov/ptacts/. Searches this session did not confirm the existence of such a petition.

Related Lemko proceedings that do NOT involve the '029 patent

These are included because they shape the practical defensive landscape — same patent family, same inventor (Shaowei Pan), same technical field, largely the same petitioner group — but none of them adjudicates a claim of the '029 patent. Do not conflate them: a claim canceled in the '988 or '990 IPRs tells you nothing directly about the '029 claims.

IPR2025-01142 — [Microsoft Corp.](/litigations/by-plaintiff/Microsoft%20Corp.) and AT&T Services, Inc. v. Lemko Corp.

• Type: Inter Partes Review
• Patent challenged: U.S. Patent No. 8,310,990 (a different patent — continuation of the '988 patent)
• Filed: 2025-06-20
• Status: Conflicting source data — GreyB/IPVerse lists status as "Discretionary Denial" with a Board entry "Director Discretionary Decision: Refer" dated 2025-11-20; Lemko's own DD request papers reference a 2026-01-08 Decision-on-Institution deadline. I could not reconcile these two dates and did not find a confirmed institution grant or denial. Treat the outcome as unresolved in this session.
• Judge panel: not confirmed
• Petition grounds: Claims 1, 3–9 challenged under 35 U.S.C. § 102 as anticipated by Flore (U.S. Pub. No. 2007/0021120 A1).
• Institution decision: not confirmed (see above).
• Final Written Decision: none — no FWD has issued.
• Settlement / termination: none reported.
• Appeal: none.
• Defensive value: Not an estoppel vehicle for '029, but it is the closest live test of the family's core "DMA" claim construction. Petitioners are arguing plain meaning of "distributed mobile architecture" per the '988 FWD, against Lemko's attempt to import a "distributed call-routing functionality" requirement. If Petitioners win that construction fight, it is useful persuasive ammunition in the AT&T district-court case — including against the '029 — but it is not binding.

IPR2023-00531 — Microsoft Corp. and Affirmed Networks, Inc. v. Lemko Corp.

• Type: Inter Partes Review
• Patent challenged: U.S. Patent No. 7,855,988 (parent/family member, not '029)
• Status: Final Written Decision issued — claims held unpatentable.
• Judge panel: FRANCES L. IPPOLITO, BRIAN D. RANGE, SCOTT RAEVSKY (per 2024-07-11 oral hearing transcript)
• Petition grounds: § 102 anticipation by Flore over claims 1, 3–9, and 20.
• Final Written Decision: Paper 31, issued 2024-09-10, finding claims 1, 3–9, and 20 of the '988 patent unpatentable as anticipated by Flore.
• Appeal: Docketed as Lemko Corp. v. Microsoft Corp., Affirmed Networks, Inc., No. 2024-2336 (Fed. Cir.); per curiam affirmed under Fed. Cir. R. 36 on 2026-04-10 (Hughes and Stoll, JJ., and Seeborg, C.D.J.). Reported at Law360 (2026-04-10).
• Defensive value: High persuasive value, zero estoppel value on the '029. The family's "distributed" claim construction and the Flore anticipation theory have now been blessed by both the Board and the Federal Circuit — but only for the '988 claims. The '988 and '029 patents are different patents (disclaimer: the '029 is a divisional of App. Ser. No. 11/393,993; the claims differ materially — '029 recites an AAA module with an HLR plus a CLR, not the Flore-oriented DMA-gateway architecture).

IPR2023-00529 — Microsoft Corp. and Affirmed Networks, Inc. v. Lemko Corp.

• Type: Inter Partes Review
• Patent challenged: U.S. Patent No. 7,653,414
• Status: Oral hearing held 2024-07-11; FWD outcome not verified in this session. I will not state a claim-level result I could not confirm.
• Judge panel: Same three-APJ panel as -00531 (Ippolito, Range, Raevsky), heard together.
• Petition grounds (reported): asserts Waylett (U.S. Pat. No. 8,184,603) among the prior art (per Lemko's recitation of Microsoft's arguments).

IPR2023-00530 — Microsoft Corp. and Affirmed Networks, Inc. v. Lemko Corp.

• Type: Inter Partes Review
• Patent challenged: U.S. Patent No. 7,548,763
• Status: Institution denied on 2023-09-25 (per the earlier litigation summary in this record). The Board rejected Microsoft's argument that Waylett's "network in a box" necessarily teaches a "computer readable medium," finding Waylett's functions are implemented in hardware.

Strategic summary

Claim status on 8,359,029: 100% UNTESTED. Not one claim of the '029 patent has been challenged, instituted, or adjudicated in any AIA trial. There are no canceled claims, no sustained claims, and no adjudicated claims. Every claim stands as issued on the face of the register — which is exactly the posture that lets a plaintiff plead a single exemplary claim (here, Claim 1) without any Board-level adverse precedent. The one thing a defendant cannot say is the thing you'd most like to say: "claim X is dead."

Estoppel landscape: empty. Section 315(e)(2) estoppel attaches only to a petitioner who obtains an FWD. Because no IPR on the '029 patent has reached an FWD (indeed, none has been filed), no party is estopped from raising any ground against the '029 patent. For a defendant currently facing the '029, the entire universe of § 102/§ 103 art remains available — including, notably, Flore itself, which has already been held to anticipate the family's sibling claims (IPR2023-00531 FWD, aff'd 2026-04-10). Flore is a printed publication and is fair game; whether it maps onto the '029's specific "AAA module / first HLR / first CLR" limitations is an open merits question, not a barred one.

Pattern signals. (1) Asymmetric petitioner behavior: Microsoft/Affirmed challenged eight Lemko patents ('763, '414, '988, '409, '111, '980, '478, '931) — not the '029. The '029 sits in the AT&T tranche ('230, '066, '322, '990, '667, '029, '020), and AT&T has so far filed — via the joint IPR2025-01142 — only on the '990. The '029 is a conspicuous gap in an otherwise systematic campaign. (2) Patent owner is an aggressive PTAB defender: Lemko (Kramer Levin — Hannah, Frankel, Price et al.) has litigated multiple IPRs to FWD and appealed to the Federal Circuit. It is a sophisticated, well-represented patent owner that will not roll over. (3) No defensive aggregator in the chain: no Unified Patents or RPX-initiated challenge on this patent was identified. (4) Exposure horizon: the patent's adjusted expiration is 2026-07-22 and it is in force and marked — so a challenger cannot wait the patent out on any useful timeline.

Recommended next steps

• If you are a defendant being asserted on the '029 patent: there is no FWD to exploit and no claim has been canceled. Do not assert otherwise, and do not assume the '990/'988 results transfer. Build your invalidity case from scratch against the actual '029 claim language (Claim 1's "AAA module … first HLR … first CLR … instructions to initiate connection of a call … via the first DMA system and the second DMA system"), and mine the Flore reference and the IPR2023-00531 record for persuasive mapping.
• Watch the live family test: the IPR2025-01142 ('990) claim-construction fight over "distributed mobile architecture" is the family's current pressure point. A Petitioners' win there is useful ammunition; note the source conflict on its status and confirm via PTACTS before relying on it. Petitioners' own filings are at PTACTS petition 1558047: PTACTS document.
• If you are contemplating an IPR on the '029: none of the § 315(e)(2) or § 325(d) estoppel channels are occupied for this patent, so you have a clean filing runway on § 102/§ 103 art. Be mindful, however, that Lemko has demonstrated it will fight institution on Fintiv / settled-expectations / § 325(d) grounds — the '990 DD request is a template of exactly the arguments it will run at you (patent in force ~12+ years; AT&T's ~decade-long knowledge; Lemko's patent-marking and commercialization).
• If you need certainty: the definitive confirmations require a live PACER/PTACTS pull — (i) the current docket state of E.D. Tex. 2:25-cv-00305, and (ii) whether a companion IPR on the '029 was filed alongside IPR2025-01142. I could not complete either within this session, and I have flagged rather than assumed those gaps. The statutory 1-year trial clock from institution is the operative milestone to diarize if such a petition exists.

I'll research the assignment record for US 8,359,029, focusing on reel/frame numbers and correspondents of record.

Assignment Record — U.S. Patent No. 8,359,029 B2

Data-integrity caveat (read first). The USPTO Patent Assignment Center's per-record fields — reel/frame and correspondent of record — were not retrievable in this session. The Assignment Center UI/API did not render for the queries I ran, and the indexed mirrors I could reach (Google Patents "Legal Events," Unified Patents portal) reproduce the event ("Assigned to…", conveyance label, assignor, recorded date) but omit reel/frame and the recording correspondent. I therefore do not invent reel/frame numbers or attorney names; the entries below are the three events of record as surfaced, with the missing metadata flagged. A PACER/Assignment Center pull is required to complete the reel/frame and correspondent columns.

Inventors

Pattern flag — present and material. Pan's departure from Motorola and the founding of Lemko triggered Motorola, Inc. v. Lemko Corp., No. 08 C 5427 (N.D. Ill.). Motorola sought a declaratory judgment that it owned eight issued Lemko patents and ten pending Lemko applications (the "Lemko patents") under Pan's and co-founder Raymond Labun's Motorola invention-assignment agreements. Per the court's opinion (Jan. 10, 2012), that opinion denied summary judgment — i.e., the ownership question survived to trial. The '029 patent sits in the divisional family that was the subject of that dispute. This is not the usual "inventors departed and the portfolio was later fire-sold" pattern; it is the inverse — an incumbent-employer ownership challenge to the original assignee, which the 2012 covenant (below) appears to have resolved.

Original assignee

Lemko Corporation (d/b/a "Lemko Corp") — a private, operating company founded 2004, based in the Chicago area (Hoffman Estates / Schaumburg, IL).

• Primary line of business: commercial network equipment / software for distributed mobile network architecture — i.e., the "DMA" (distributed mobile architecture) node and the Node1 / Node1 DMA product line.
• Did it ship a product embodying the claims? Yes — this is documented, not inferred. In the E.D. Tex. complaint and in Lemko's IPR2025-01142 Patent Owner Preliminary Response, Lemko states it commercialized the claimed subject matter and patent-marked its products. The complaint describes a Sept. 24, 2013 demonstration at AT&T Labs ("Middletown, New Jersey") of "operating models of its patent-practicing Node1 products," marked with Lemko's patent numbers, and a 2015 vehicle-mounted mobile Node1 DMA demonstration to AT&T. (RPX litigation document; PTAB POPR PDF)
• Current status: Operating, not dissolved, not in bankruptcy on the record I could retrieve. It is actively litigating as plaintiff (2:25-cv-00305, E.D. Tex., Judge Gilstrap) and is the recorded owner, but it has encumbered the portfolio with a 2025 security interest (below), which is a distress-financing tell.

  • Correspondent: NOT RETRIEVED
  • Context: Securitization — grant of a security interest (collateral lien) in the Lemko portfolio, not a sale. Recorded 8 days after Lemko filed 2:25-cv-00305 against AT&T (2025-03-17), which is the signature of litigation financing / monetization against the portfolio.

Chain-length finding: the '029 patent has exactly one true assignment of title (inventor → Lemko, 2010). There is no chain of LLC-to-LLC conveyances on this patent. The other two recorded events are a covenant and a lien. This is a thin chain by NPE standards.

NPE / troll-pattern signals

1. Shell-entity transfer — NOT PRESENT (as to title). Title never left Lemko Corporation. The 2025-03-25 Piccadilly Patent Funding entry is expressly recorded "AS SECURITY HOLDER" and conveyed by "PATENT SECURITY AGREEMENT" — a lien, not an assignment. There is therefore no evidence of a move "from an operating assignee to a licensing-only LLC" as owner. Caveat/watch item: Piccadilly Patent Funding LLC is itself a single-purpose funding vehicle; it appears in the federal dockets as a participant in patent cases alongside Davidson Kempner Capital Management LP — e.g., docket participant listing in MYW Semitech, LLC v. …, No. 1:2025-cv-00504 (Justia dockets). Piccadilly also appears in the Third-Party Litigation Funding disclosure materials filed with the U.S. courts (uscourts.gov TPLF document). So the security holder is an identified litigation-finance party — evidence of distressed monetization, but not evidence that an NPE took title.

2. Known asserter in the chain — NOT PRESENT (per the enumerated lists). Neither Lemko Corporation, Motorola Solutions, nor Piccadilly Patent Funding LLC matches the named rosters (Acacia, Marathon, IV, IPNav, Wi-LAN, Mosaid/Conversant, Vringo, Pendrell, Innovatio, MPHJ, Lumen View, Round Rock, Document Generation Corp, Spangenberg entities). However, note the inverse: Lemko is the plaintiff, asserting § 271(a) against AT&T in Count XI of 2:25-cv-00305, and had a prior assertion campaign against Microsoft/Affirmed Networks (N.D. Tex., 3:22-cv-00363). Lemko is a serial operating-company plaintiff, which is a separate posture from the NPE rosters.

3. Repeat correspondent across the chain — INSUFFICIENT DATA. This is the strongest NPE tell per the task instructions and it could not be evaluated, because the Assignment Center's correspondent field did not render and the indexed mirrors (Google Patents Legal Events, Unified Patents portal) do not carry it. I make no finding. A manual pull of the three recordings is required before any recurrence conclusion can be stated; the linked check required by the instructions is a comparison of the recording correspondent on the 2010-11-15, 2012-02-21, and 2025-03-25 entries. This is the top open item for follow-up.

4. Cascading transfers — NOT PRESENT. One title assignment (2010) and two non-title events (2012 covenant; 2025 lien). There is no sequence of chained LLC conveyances within 24 months, and no shared-correspondent address pattern can be shown (see signal 3). The 2012 and 2025 events are 13 years apart.

5. Pre-litigation transfer — NOT PRESENT; instead, a post-filing encumbrance. The 2025-03-25 security agreement was recorded 8 days after the E.D. Tex. complaint was filed (2025-03-17). It is therefore not a pre-suit assignment arranged to manufacture standing or venue — title was already Lemko's and remained so at filing. The timing is instead consistent with litigation funding secured against / contemporaneous with the suit.

6. Bankruptcy fire-sale — NOT PRESENT. No Chapter 7/11 proceeding involving Lemko Corporation was identified in the retrieved sources, and no sale of this patent in a bankruptcy proceeding is of record. (The 2025 security interest is distress-adjacent, but a lien is not a bankruptcy sale.)

7. Privateering — NOT PRESENT / UNSUBSTANTIATED. The classic privateering pattern (an operating company transferring to an NPE that asserts on its behalf against competitors) would require Lemko to have transferred title to an asserter. It has not; Lemko asserts in its own name. The Piccadilly security interest is a creditor relationship, which is a different structure and does not by itself establish privateering. Note: Motorola's 2012 covenant runs the other direction (Motorola promising not to sue Lemko) and is defensive, not offensive.

8. Defensive aggregator — NOT PRESENT. The chain does not terminate at RPX, AST, LOT, Unified Patents, or OIN. The patent is live and being asserted by its owner.

Verdict

Operating-company assertion

Justification (2–3 sentences): The chain of title is short and never left the original assignee: ShaoWei Pan → Lemko Corporation (recorded 2010-11-15), with the sole other recorded events being a defensive covenant not to sue running to Lemko from Motorola Solutions (recorded 2012-02-21) and a security interest granted by Lemko to Piccadilly Patent Funding LLC as security holder (recorded 2025-03-25) — neither of which transfers ownership. Lemko ships the claimed technology (patent-marked Node1 / Node1 DMA products, per its own PTAB and district-court filings) and is asserting the '029 patent in its own name against AT&T in Count XI of 2:25-cv-00305 (E.D. Tex., filed 2025-03-17), which is the classic operating-company-vs-competitor posture. The Piccadilly/Davidson Kempner security interest recorded 8 days post-filing is a distress-financing overlay worth flagging — it signals the portfolio is collateralized against a third-party litigation funder — but under the instruction not to infer NPE status without evidence of a title transfer, the record supports operating-company assertion, not NPE.

Open items for a PACER/Assignment Center pull (unverified here):

1. Reel/frame and correspondent on all three recordings — needed for signal 3 (repeat correspondent).
2. Whether a separate 2006 assignment of the parent application 11/393,993 exists.
3. Any 2012 release/termination entry tied to the Motorola covenant.
4. Whether the Piccadilly security interest has been assigned, enforced, or foreclosed since 2025-03-25.

*Flagged contradiction with prior sections: none on the facts. The prior litigation section called the '029 "asserted" in 2:25-cv-00305 based on a complaint exhibit; this analysis independently confirms that via Count XI and the verbatim Claim 1 quotation ("A non-transitory computer readable storage medium of a first distributed management architecture (DMA) system…"), and adds that the 2025-03-25 Piccadilly recording is not an assignment of title — a point the earlier bibliographic table left ambiguous by listing it under "Assignments of record." That characterization should be corrected to "security interest / lien of record."*

I'll research the prior-art references cited on the face of US 8,359,029 and assess them against the claims. Let me run several targeted searches.

The first searches didn't surface the front-page citation list. Let me target the citation/pedigree data directly.

Let me try to retrieve the actual patent document PDF and citation data directly.

Important limitation up front

I must be straight with you about what I could and could not verify.

Search target: I searched specifically for 8359029 / US 8,359,029 B2. I did not substitute or auto-correct any similar number (e.g., 8,359,092; 8,359,290; 8,359,039).

What I could not retrieve: The task asks me to analyze "each patent citation for 8,359,029." The authoritative full text of US 8,359,029 that is in my possession (the Google Patents rendering, fetched 2026-09-29) does not contain the front-page "References Cited" / "Patent Citations" table. That rendering reproduces the abstract, the specification, the figure list, and the classifications, but omits the examiner/applicant citation tables. My web searches did not surface the citation table either — the queries returned the same specification text plus unrelated search reports from other patent families.

I will not fabricate the list. Inventing citation entries (numbers, dates, "potentially anticipates claim X") would violate the operating rule to avoid fabrication. So this deliverable is partial: I give you (1) the verified record I do have, (2) the honest statement of what is missing, and (3) a rigorously-labeled framework for the § 102 analysis so the citation list can be dropped in once pulled.

1. Verified record for the target patent (from the authoritative text)

Critical date for § 102: Because the '029 patent is a divisional claiming priority to 2006-03-30, the presumptive critical date for prior art is 2006-03-30 (subject to a Samsung v. Infuse‑type inquiry into whether every claim actually finds § 112 support in the parent 11/393,993). Any reference dated after 2006-03-30 is only relevant under § 102(e) if it has an earlier effective U.S. filing date, or under § 102(a)(2) post-AIA analysis — which does not apply here because the application was filed in 2010 but claims pre‑AIA priority, so pre‑AIA §§ 102(a)/(b)/(e) control.

2. What the specification itself cites

The '029 specification contains no explicit "prior art" citation section and does not name any prior-art patent or publication in its body. The only internal documents it references are:

• Ser. No. 11/393,993 (its parent application — same disclosure, not prior art to its own divisional), and
• co‑pending family applications (per the "Cross Reference"/"Priority" fields: 13/718,054 → US 8,688,111; and the sibling patents 7,653,414; 7,855,988; 8,310,990; etc.).

So any cited references exist only on the printed front page (Examiner's Patent Citations and Applicant's citations), which I could not pull.

3. Candidate prior art — CLEARLY LABELED AS NOT VERIFIED AS CITED ON THE '029 FACE

The following is not a "citations of record" list. These are references I can tie to the same technical field and family from the litigation/PTAB record, offered only so the § 102 analysis can begin once the actual face citations are obtained. Do not treat any of these as an on-face citation of the '029 patent without confirming in the source.

Recommendation: the genuinely useful § 102 candidates will be the Examiner's cited U.S. patent documents from classes H04Q 7/00, H04W 8/02, H04W 88/02, H04L 12/66 (gateway/softswitch), and the distributed‑HLR/roaming literature circa 2000–2005 (e.g., GSM/ANSI‑41 "distributed HLR," intelligent‑network, and softswitch/packet‑BSC references). I did not confirm which specific ones appear on the '029 face.

4. § 102 mapping framework by claim group (ready to apply once citations are pulled)

Using the earlier plain-language claim grouping (flagged there as reconstructed, not verbatim), the § 102 attack surface is:

• Group 1 / 4 / 8 (HLR + CLR mirroring; AAA module embedded in a DMA): § 102 anticipation requires a single reference disclosing (a) a first node holding a first subscriber register and (b) a replicated register of a second node's register, plus (c) logic to initiate a call across the two nodes. A § 102 reference must have all three in one document; absent that, this group is a § 103 case (distributed-HLR art + peer-to-peer gateway art).
• Group 2 / 6 (look-up order: home HLR first, then neighbor CLR): Anticipation turns on whether the reference discloses the ordered two-step lookup. Generic "location register lookup" art will likely be § 103, not § 102, absent the ordering.
• Group 3 / 7 (roaming: location-update relay through a second DMA to a third DMA, then peer-to-peer IP call): The strongest anticipation target is roaming/location-update art. Flore (US 2007/0021120) maps to the handover/location-update messaging but must clear the date bar noted above.
• Group 5 (single-DMA local call via local IP addresses): Highly likely covered by ordinary mobile-switching/intra-BSC call-completion art predating 2006 — a strong § 102 candidate class, but again, which references are of record is unverified.
• Group 9 (system: first/second/third DMA over an IP network, with second and third CLRs): Requires a reference disclosing a three-or-more-node IP-interconnected switch fabric with per-neighbor replicated registers; likely § 103 over clustered/softswitch art unless a single reference exists.

5. What you need to do to complete this task

To produce the verify‑grade deliverable you asked for, the front‑page citation tables must be pulled from a source that includes them:

1. USPTO Patent Public Search (ppubs.uspto.gov) — open US 8,359,029, "Patent Citations" panel (Examiner + Applicant, U.S. and foreign).
2. USPTO PatentCenter / Patent Application 12/946,012 — the file wrapper contains the PTO‑892 (Notice of References Cited) and any IDS (SB/08) the applicant filed, which give the exact on‑face list.
3. Google Patents → US8359029 → "Patent Citations" and "Cited By" sections (these render the tables that the abstract/spec‑only extraction I have omitted).

Once those tables are in hand, each entry goes into the table format in § 3 above with: full citation, publication date and effective filing date (to test § 102(e)), one‑paragraph summary, and the specific claim group(s) it can anticipate — with the caveat that any post‑2006‑03‑30 publication is only § 102(e) art if its provisional/utility filing predates 2006‑03‑30.

Bottom line: I confirmed the patent identifier and its bibliographic/priority record, but I could not retrieve the actual cited‑references list for US 8,359,029 in this session, and I have deliberately not invented one. The § 102 analysis above is a framework keyed to the claim groups; it is ready to be populated the moment the verified citation table is available.

I'll ground this analysis in the actual prior-art references tied to this patent rather than reconstructing from memory. Let me pull the cited-art and family records.

Let me pin down the specific references that have actually been asserted against this Lemko family (Mauer, Waylett, Flore) and the '029 claim text.

Let me nail down the remaining prior-art citations (the '029 face references, plus Mauer, Waylett, Flore, and Cope full identities).

Obviousness Analysis — U.S. Patent No. 8,359,029 under 35 U.S.C. § 103

0. Scope, sourcing, and an important caveat about "the Prior Art section"

The Google Patents rendering of US 8,359,029 that I was given reproduces the abstract, specification, and figure list, but its "Prior Art" section surfaces only keyword metadata — the prior-art keywords logged for this record are: dma, dma system, mobile subscriber, mobile, registered. It does not reproduce a full "References Cited" list. I therefore built this analysis from three grounded sources rather than inventing citations:

1. The cited-art list on the sibling patent in the same family, US 8,310,990 ("System, method, and device for routing calls using a distributed mobile architecture," Pan/Lemko), whose face lists the family's cited U.S. patents and non-patent literature.
2. The prior art actually asserted against this Lemko family in PTAB proceedings (Mauer, Waylett, Flore, Cope).
3. The patent text itself (specification passages describing the CLR, HLR, VLR, and the Fig. 7–8 routing flows).

Two things I could not verify and will not fabricate: (a) the exact numbered claim text of the '029 (my earlier section flagged this; the only verbatim claim language available is Claim 1 as quoted in the E.D. Tex. complaint, summarized below); and (b) the full bibliographic identity of every face reference (I have the numbers, not all titles). I flag each place where that matters.

1. Governing law, effective date, and POSITA

• Pre-AIA § 103 applies. The '029 was filed 2010-11-15 (Application 12/946,012) as a divisional of Ser. No. 11/393,993 filed 2006-03-30. Because the application was filed before March 16, 2013, the AIA's § 102/103 do not govern; pre-AIA § 102(e) and the § 103(c) common-ownership safe harbor are in play.
• Critical date for art: the '029's effective filing date is the 2006-03-30 parent filing date. A reference must therefore predate that date (by filing for § 102(e) art, or by publication/issue for § 102(a)/(b) art).
• POSITA. In IPR2025-01142 (the '990 IPR), Lemko adopted Petitioners' stipulated level for a patent with a 2008 priority date: "a bachelor's degree in electrical engineering, computer engineering or an equivalent, as well as two years of industry experience related to telecommunications networks." For the '029, whose priority reaches back to 2006, the POSITA is the same profile with knowledge of ANSI‑41/GSM mobility management, HLR/VLR roaming, SS7/MAP signaling, VoIP and 3GPP IP transport, and IP mesh/ad-hoc networking.

2. The prior-art corpus available

⚠️ Common-ownership note: Lemko's own earlier applications (e.g., U.S. 8,036,158; 8,086,920; and the '029's own parent, which issued as U.S. 7,856,233) are not usable § 103 art against the '029 if commonly owned and within the pre-AIA § 103(c) safe harbor. Any obviousness case must rest on third-party art.

3. Limitation mapping to the independent-claim groups

Using the claim groups from my earlier section (numbering unverified), the § 103 attack splits into three difficulty tiers:

Tier 1 — plainly disclosed/obvious in the art.

• HLR, VLR, and a distributed multi-node architecture → Waylett (NIB with HLR/VLR), Mauer, Rautiola, Heinonen, Flore.
• MSC module + BSC module embedded in one apparatus → Waylett's NIB literally "contains a single enclosure that includes a mobile switching center, base station controller, and base station transceiver."
• IP network between nodes / location-update request → acknowledgement → connect → Flore's PDP-context query/response and update-request messaging, plus Mauer.
• Register fields (IMSI, ESN, MDN, location indicator, TLDN, registration indicator, timer, MSC/ISDN/VoIP preference indicators) → these are verbatim ANSI‑41/GSM record fields (IMSI, ESN, MDN, TLDN are standard identifiers; periodic-registration timers and interface preference are routine network design). The preference-indicator dependent features are also the subject of Lemko's own sibling '990/'414 "destination preference register" claims and are akin to least-cost/interface-preference routing.

Tier 2 — the "AAA module" claim group. Hoffpauir H1918 (integrated authentication center) + Waylett (RADIUS server co-located with MSC/BSC/HLR/VLR in the box) map onto an "AAA module embedded in a computer-readable medium."

Tier 3 — the two hard, potentially dispositive limitations.

1. "Community location register" (CLR) — a local register that replicates a neighbor DMA's HLR (and, in the module claims, both a first CLR mirroring this DMA's HLR into a neighbor and a second CLR holding a neighbor's registrants).
2. "Peer-to-peer IP connection" between DMAs, and the "computer-readable storage medium" framing of the CRM claims.

4. Proposed combinations and the motivation to combine

Ground A — Mauer + Waylett (primary § 103 ground)

This is the exact combination Microsoft actually ran against Lemko's sibling '414 patent in IPR2023-00529, where Petitioners' exhibit list identifies Mauer (7,395,085) and Waylett (8,184,603).

• Waylett supplies the collapsed core: a single-enclosure node with an MSC, BSC, BTS, HLR, VLR, and RADIUS server — the structural predicate for the '029's "AAA module… embedded within the computer readable medium" and for local (intra-node) call completion (claim group 5).
• Mauer supplies flexible multi-network routing and the "alternative communication option," supplying the cross-node routing and subscriber-data-lookup teaching.
• Motivation to combine: both references target the same problem the '029 recites — economically extending wireless coverage without a full centralized core. A POSITA seeking to serve low-density/rural markets would combine Waylett's compact multi-function node with Mauer's flexible routing to reduce backhaul and core cost. KSR permits exactly this "arrange the known elements to achieve a predictable result" rationale.

Ground B — Flore alone, or Flore + Mauer/Waylett

Flore teaches an Inter‑AS Anchor that stores routing information (PDP context) for a UE served by a second gateway, receives a communication destined for that UE, and relays it to the second gateway over a network, in response to a query. Petitioners used this against the sibling patents (IPR2023-00531; the '990 petition reuses it).

• Mapping: Flore's gateway-side storage ≈ the CLR's "store information associated with a second HLR"; Flore's update/query/response ≈ the '029's location-update and acknowledgement flow (claim group 3); Flore's GGSN location-register function ≈ the HLR limitation; Flore's PDP context ≈ MDN/TLDN-style location data.
• Motivation to combine / why obvious: routing traffic to a serving node using cached routing data for a roaming device is the standard mobility-management paradigm (ANSI‑41/GSM inter-system handoff; Mobile IP). A POSITA would see Flore as a straightforward application of known register-lookup-and-relay.

Ground C — Waylett (NIB) + Rautiola/Heinonen/Csapo (register replication) + Yanikomeroglu/Tseng (peer-to-peer)

This is the combination that most directly attacks the CLR and peer-to-peer limitations.

• Register replication → CLR: ANSI‑41/GSM registration already teaches copying subscriber data from an HLR into a visited register (VLR) when a device moves (Rautiola, Heinonen, Csapo). A POSITA seeking to cut SS7/MAP signaling and call-setup latency in a multi-node community network would naturally extend that known "cache the neighbor's subscriber data locally" technique into a per-neighbor community register — i.e., the CLR. The '029's own specification reinforces this by describing the CLR as storing a neighbor's IP address, DMA-ID, GPS/GSM location, and a "neighborhood (NB) list" — all routine network-management fields.
• Peer-to-peer IP → the face-cited NPL does the heavy lifting: Yanikomeroglu (2002) teaches two-hop peer-to-peer relaying in cellular radio networks; Tseng (2003) teaches integrating Mobile IP with ad hoc networks. Combined, these supply both the technical feasibility and an explicit motivation to link self-contained cellular nodes in a peer-to-peer IP mesh rather than through a hub.
• Motivation to combine: Waylett provides the multi-node "community" network and in-box core; the NPL provides the flat, self-forming, peer-to-peer IP transport; the register art provides the replicated-location mechanism. The shared objective — low-cost, backhaul-minimizing coverage extension — is the articulated reason to combine.

Ground D — Hoffpauir H1918 + Waylett (AAA-module claims)

H1918's "Integrated Authentication Center" fused authentication with HLR data; Waylett's NIB co-locates RADIUS + HLR + VLR. Together they render obvious the AAA module with HLR + CLR + VLR of claim group 4.

5. Counter-evidence and why the prima facie case is contestable

An honest § 103 analysis must account for the actual PTAB record on this family, which cuts against the combinations above:

1. The "computer-readable storage medium" problem. In IPR2023-00530 the Board denied institution, agreeing with Lemko that Waylett's NIB implements MSC/BSC/CDR functions in hardware network cards, not on a computer-readable medium, and that it would not have been obvious to the POSITA to re-implement them in software. Because several '029 claim groups are framed as a "non-transitory computer-readable storage medium" with embedded modules, the same Waylett deficiency attacks Grounds A and C. This is the single strongest non-obviousness argument.
2. The CLR finding. In IPR2023-00529 Lemko argued that Mauer+Waylett "do not render obvious the community location register limitation" — Petitioners apparently had to stretch Mauer's voicemail server into the CLR role. If the Board agreed, the CLR limitation is the '029's strongest differentiator over Mauer+Waylett.
3. "Distributed" ≠ hierarchical. Across the '988 and '990 matters, Lemko's central defense is that Flore's 3G/4G architecture is centralized and hierarchical, not a distributed mobile architecture. A POSITA reading the '029's "distributed mobile architecture" term in light of a construction requiring distributed call-routing functionality and peer-to-peer connections could find Flore inapposite. (Whether the Board must construe "distributed" at all was itself an issue on appeal in No. 24‑2336.)
4. Secondary considerations (Graham factor 4). Lemko has documented a coherent objective-indicia story that must be weighed: its commercial Node1 product allegedly practices the claims (nexus); the invention addressed a long-felt need for low-cost distributed deployment; the industry praised Node1 (AT&T's Ms. Chiosi called it a "radical design"); and Lemko's 2025 complaint pleads that AT&T copied/adopted the architecture. ⚠️ But note a date problem: the AT&T 2012 NFV whitepaper is after the '029's 2006-03-30 priority date and therefore is not § 102/103 prior art — it is only evidence of later industry recognition, and its nexus to these claims (vs. the '990/'414) is disputed.

6. Bottom line

• Strongest prima facie § 103 case: Mauer (7,395,085) + Waylett (8,184,603), optionally + the peer-to-peer NPL (Yanikomeroglu 2002; Tseng 2003) to reach the IP-mesh limitation, and + a register-replication reference (Rautiola/Heinonen/Csapo) to reach the CLR. Motivation: cost-driven coverage extension and backhaul reduction — the same rationale, and the same reference pair, that Microsoft actually used against the sibling '414 patent.
• Second case: Flore (alone or with Mauer/Waylett) for the location-update / store-and-relay / location-register limitations, relying on the standard mobility-management paradigm for motivation.
• Where the claim is most vulnerable to survivorship: the "non-transitory computer-readable storage medium" framing (the Board's Waylett-is-hardware finding) and the "community location register" as a replicated neighbor HLR. If those two limitations are read narrowly and the "distributed" term is construed as Lemko urges, the '029 plausibly survives the Mauer/Waylett art — which is likely why no IPR has yet been filed against the '029 itself (the challenges on record target the '414, '988, '990, and '763 patents, not the '029).
• Verification items I could not close: exact '029 claim text/numbering; full citation for Cope; titles for Magnusson 6,122,499 and Heinonen 6,418,838; and the precise 102(e) filing dates for Waylett's family and Flore. Each should be confirmed against USPTO Patent Public Search / PACER / the PTAB record before this analysis is relied upon.
