US Patent 6,876,979 — Summary and Search Findings

Search caveats (read first)

• My direct searches of the USPTO's own database (patents.google USPTO mirror / USPTO identifiers) returned no results through the search tool; the authoritative text below comes from the full patent text you supplied (Google Patents snapshot, fetched 2026-08-31) and is corroborated by freepatentsonline.com, patents.justia.com, Unified Patents (Patroll/Portal), and CAFC sources.
• Note a date discrepancy: your prompt states "Current Date: April 26, 2026," but the live CAFC/Fed Circuit Blog result discussed below is dated August 28, 2026. Per the operating rules, I am reporting the search result as current ground truth rather than discarding it.
• Search results confirm this is the correct patent — US 6,876,979 B2 (application 10/217,871) — not a similar number. No near-number confusion found.

Bibliographic data

Abstract (verbatim)

"Systems and methods are provided for supporting electronic commerce in an environment in which multiple service providers each have associated vendors and in which a user may maintain an account at a service provider that is different from the service provider associated with the vendor from which a user makes an on-line purchase. Both tangible products and electronic content products may be sold using the system. A bridge computer may be used to facilitate interactions between service providers. The bridge computer may be used to implement service charge fees, to reimburse service providers for credit card transaction fees, to reimburse service providers with appropriate referral fees, and to otherwise support operation of the system."

Independent claims — plain-language overview

The patent has 13 claims total, and only claim 1 is independent (claims 2–13 all begin "The method defined in claim 1…").

Claim 1 (method): In an e-commerce system with a bridge computer, a user at a user device buys a product at a stated price from a vendor whose web site runs on a vendor computer over a network. The vendor is associated with one of several service providers (each having a service provider computer), and the user has an account at one of those service providers. The method requires:

1. Debiting the user's account by the purchase price when the user buys the product;
2. The bridge computer determining whether the vendor is associated with the same service provider that holds the user's account, or a different one; and
3. Conditional crediting:
   • If same service provider → credit the vendor from the user's account funds at that service provider; or
   • If different service provider → credit the vendor using funds from the vendor's associated service provider, and use the bridge computer to reimburse that vendor-side service provider with the purchase price drawn from the user's account.

In short: the invention lets a user's stored-value account at one portal/ISP be used to pay a vendor affiliated with a rival service provider, with the bridge computer acting as clearinghouse so the two service providers never transact directly.

Dependent claims 2–13 (topics only): credit-card service-charge reimbursement (2, 11); referral fees to the user's service provider (3); bridge service charge collection (4); scheduled account settlement (5); database of vendor–service-provider associations (6); bridge-provided buy-option screen (7); vendor-ID-based determination (8); vendor-ID + user-ID determination (9); new-account creation at the vendor's service provider (10); tangible product (12); intangible product (13).

Litigation / CAFC 2026 docket findings (from live search)

• The patent is owned and actively asserted by AML IP LLC (a patent-assertion entity), with dozens of district-court cases filed 2020–2024 (W.D. Tex., E.D. Tex., D. Del., S.D.N.Y., etc.) against retailers and payment platforms (e.g., Blizzard, Coinbase, ReBilly, AffiniPay, Bath & Body Works, The Buckle, Nebraska Furniture Mart, Priority Tire, Ardene USA). Many were voluntarily dismissed; no merits rulings in those.
• CAFC appeal 2025-1280, AML IP, LLC v. Bath & Body Works Direct, Inc. (with The Buckle, Inc.) — oral argument was held and, per the Fed Circuit Blog (dated August 28, 2026), the Federal Circuit issued a precedential opinion affirming the Eastern District of Texas dismissal of the '979 patent on both improper-venue and § 101 patent-eligibility grounds. AML did not dispute the merits of the venue/eligibility rulings on appeal, arguing only that the district court should not have reached ineligibility after dismissing for venue; the CAFC rejected that argument and affirmed.
• Separately, a PTAB petition (IPR2022-00319) was filed but not instituted.

Uncertainty notes

• I could not directly query the USPTO's current full-text database through the search tool (no results returned); the bibliographic/claim data is from the authoritative patent text provided plus corroborating third-party patent databases.
• The CAFC opinion details beyond the blog summary (case caption formatting, exact holding language) are not verified from the slip opinion itself; the blog identifies appellees as "Bath & Body Works Direct, Inc. and The Buckle, Inc." while the CAFC oral-argument page lists the case as AML IP, LLC v. Bath & Body Works, LLC (appeal 2025-1280) — a minor caption inconsistency I could not resolve.

Litigation Involving U.S. Patent No. 6,876,979 ("Electronic Commerce Bridge System")

Important preliminary notes

1. Date discrepancy flagged: Your instructions state the current date is April 26, 2026, but live search results include a Federal Circuit precedential opinion dated August 28, 2026 affirming dismissal of the '979 patent. Per the operating rules (search results trump training data), I am treating the August 2026 CAFC result as current ground truth. The litigation picture below reflects that.

2. Plaintiff in essentially every case: AML IP, LLC (a Texas LLC, patent-assertion entity; successor-in-interest to the original assignee PayByClick Corp via a chain of assignments ending at AML IP LLC in 2020). Plaintiff's counsel is almost always William P. Ramey III / Ramey LLP (later Ramey & Browning PLLC), with David L. Hecht (Hecht Partners) appearing in the D.N.J. case.

3. The '979 patent is expired (adjusted expiration 2023-03-24), which is relevant context for the litigation tail (no ongoing damages accrual).

A. Federal Circuit appeal (most significant development)

AML IP, LLC v. Bath & Body Works Direct, Inc. (and The Buckle, Inc.)

• Case No.: 2025-1280 (Court of Appeals for the Federal Circuit)
• Appeal from: E.D. Tex. (see District Court cases below)
• Status/Outcome: Affirmed (precedential), August 28, 2026 (opinion by Judge Prost). The CAFC held the district court did not err in reaching 35 U.S.C. § 101 patent-eligibility after first dismissing for improper venue under 28 U.S.C. § 1400(b). AML did not challenge the merits of the venue or eligibility rulings on appeal — only the district court's discretion to reach eligibility after finding venue improper. The CAFC rejected that argument, distinguishing venue (waivable) from subject-matter jurisdiction. (Sources: Fed Circuit Blog, 8/28/2026; IPWatchdog, 8/31/2026.)

The Google Patents litigation record for the '979 patent (Unified Patents portal links) lists dozens of additional dockets, all with AML IP, LLC as plaintiff, including:

• W.D. Tex. (Waco): 6:20-cv-01197, 6:20-cv-01198, 6:20-cv-01199 (filed 2020); 6:21-cv-00184, 6:21-cv-00419, 6:21-cv-00522, 6:21-cv-00524, 6:21-cv-00525, 6:21-cv-00599, 6:21-cv-00600, 6:21-cv-00605, 6:21-cv-00789, 6:21-cv-01021; 6:22-cv-00175, 6:22-cv-00177, 6:22-cv-00178, 6:22-cv-01089, 6:22-cv-01090, 6:22-cv-01091, 6:22-cv-01257, 6:22-cv-01262, 6:22-cv-01263; 6:23-cv-00023 through 6:23-cv-00033 (the "Transform" cluster); 6:23-cv-00248 (Google); 6:23-cv-00736, 6:23-cv-00836; 6:24-cv-00235, 6:24-cv-00239, 6:24-cv-00275, 6:24-cv-00276, 6:24-cv-00278, 6:24-cv-00381, 6:24-cv-00382, 6:24-cv-00383, 6:24-cv-00385, 7:24-cv-00175, 7:24-cv-00190, 7:24-cv-00191.
• E.D. Tex.: 4:22-cv-00214, -00215, -00216, -00222, -00223, -00225, -00226; 2:23-cv-00582, 2:23-cv-00602, 2:23-cv-00609, 2:23-cv-00615; 2:24-cv-00004, -00005, -00006, -00024, -00211, -00222, -00223, -00275.
• D. Del.: 1:21-cv-00174, 1:21-cv-00266, 1:24-cv-00701.
• S.D.N.Y.: 1:23-cv-11264, 1:23-cv-11270, 1:24-cv-00390.
• Other: 3:17-cv-04148 (N.D. Cal.); 8:21-cv-00371 (C.D. Cal.); 5:21-cv-00294 (E.D.N.C.); 3:23-cv-00102 (N.D. Tex.); 2:23-cv-00668 (W.D. Wash.); 1:24-cv-01784 (N.D. Ga.); 2:24-cv-05852 (D.N.J.).

Per the same record, most of these were voluntarily dismissed without prejudice or are otherwise closed without merits rulings; the two merits-level defeats are the E.D. Tex. § 101/venue dismissals (affirmed at the CAFC) and the PTAB non-institution (below).

D. PTAB proceedings

• IPR2022-00319 — Petition for inter partes review of the '979 patent: filed (petitioner context: Unified Patents-related prior-art challenge), NOT INSTITUTED (denied; no merits trial). Prior art was also crowdsourced via Unified Patents' Patroll program ($2,000 bounty on claim 1, 2021).

E. Summary of outcomes

Confidence notes: Defendant names for the Section C case-number list are from the Unified Patents portal case-level links embedded in the Google Patents record and were not individually re-verified this session (the portal requires login for full case detail). The CAFC opinion text itself was not retrieved (only the Fed Circuit Blog summary and IPWatchdog article), so the exact slip-opinion caption (Bath & Body Works Direct, Inc. vs. Bath & Body Works, LLC) remains slightly inconsistent across sources. No litigation involving a different plaintiff than AML IP, LLC (or its assignor predecessors) was found for this patent.

Proceedings overview

There is one AIA trial proceeding on file for US 6,876,979: IPR2022-00319, which was denied at institution (all 13 claims challenged, none instituted). There are zero active proceedings, zero Final Written Decisions, zero settled or terminated trials, and zero claims invalidated or sustained by the PTAB. The bottom-line defensive posture: the patent is entirely untested on the merits before the PTAB — every claim (1–13) remains technically in force, but the far stronger defensive development is outside the PTAB entirely: the Federal Circuit's precedential affirmance (2025-1280, Aug. 2026) that the claims are invalid under § 101.

⚠️ Data discrepancy flagged per operating rules: the USPTO ODP block in the prompt states "no AIA trial proceedings on file," but live search results (Patexia; Google Patents' own litigation tab) confirm IPR2022-00319 exists. The ODP feed appears to have not indexed this proceeding; the search results are treated as ground truth.

IPR2022-00319 — Askeladden L.L.C. v. AML IP LLC

• Type: Inter Partes Review
• Filed: 2021-12-15
• Status: Institution Denied (Patexia's verbatim status; Google Patents labels it "Not Instituted - Merits," which suggests a merits-based § 314(a) denial — i.e., failure to show a reasonable likelihood of prevailing — rather than a Fintiv/discretionary denial)
• Judge panel: Michael L. Woods (author of the institution decision), Patrick R. Scanlon, Robert Kinder Jr. (per Patexia)
• Petition grounds: The petition challenged all 13 claims (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13). The specific prior-art references and statutory basis (§ 102/§ 103) were not recoverable from the search results I obtained; I will not speculate on the exact art.
• Institution decision: Denied, 2022-05-11. I could not retrieve the decision text, so I cannot quote the panel's reasoning. The "Not Instituted - Merits" label on Google Patents indicates the denial was on the merits of the unpatentability showing, not a discretionary Fintiv denial — treat that as a gloss, not as verified language from the decision.
• Final Written Decision: None — the proceeding never went to trial.
• Settlement / termination: No settlement. The case terminated by operation of the institution denial.
• Appeal: None possible. Denials of institution are statutorily non-appealable (35 U.S.C. § 314(d)); there is no CAFC appeal of this proceeding.
• Defensive value: Limited but real. The Board already looked at the petitioner's best case against every claim and declined to institute — a repeat petitioner attacking the same claims with substantially the same art faces an uphill credibility battle. That said, an institution denial creates no estoppel and no merits findings; it does not foreclose a better-crafted petition with different art. For a defendant today, this proceeding is not the lever — the § 101 lever is.

Strategic summary

Claims: CANCELED vs. SUSTAINED vs. UNTESTED. No PTAB proceeding has ever produced a Final Written Decision on US 6,876,979. No claims are canceled and none are "sustained" in the IPR sense — all 13 claims (claim 1 independent; claims 2–13 dependent) are UNTESTED before the PTAB on the merits. The only claim-level adjudication of this patent anywhere is the district court's § 101 ineligibility ruling, affirmed by the Federal Circuit as precedential on 2026-08-28 in AML IP, LLC v. Bath & Body Works Direct, Inc. (No. 2025-1280). That is the current dispositive weakness of the patent, and it is far more potent than anything the PTAB record offers.

Estoppel landscape. Because IPR2022-00319 was denied at institution, no § 315(e)(2) estoppel attaches to anyone — estoppel only arises from a Final Written Decision. Askeladden, its privies, and any new defendant are all free to raise any ground, including the very art Askeladden used (though the Board's refusal to institute signals that art was not persuasive). Critically, § 101 eligibility is not an IPR ground at all — Alice/Mayo challenges are completely outside IPR estoppel, which is why the venue/§ 101 dismissal strategy succeeded where the IPR failed. Prior-art grounds remain fully available for any defendant that wants to file a fresh, better-documented IPR.

Pattern signals. One signal stands out: Unified Patents ran a $2,000 prior-art bounty ("Patroll" contest) on this exact patent from 2021-03-02 to 2021-07-01, seeking winning prior art on at least claim 1 and identifying AML IP as an NPE asserting against Blizzard, Kongregate, Coinbase, ReBilly, Payment Approved, and AffiniPay. The IPR followed roughly five months later (filed 2021-12-15). The petitioner, Askeladden L.L.C., is consistent with the defensive-aggregator playbook (Unified Patents frequently uses separately named LLC vehicles), but I could not confirm the Askeladden–Unified Patents relationship from the sources retrieved — flag that as plausible, not verified. Also note: AML IP has been extremely litigious (dozens of district-court cases 2020–2024, mostly voluntarily dismissed) but has now lost a precedential CAFC appeal on eligibility — the patent's practical enforcement value has collapsed even though the PTAB record is a blank slate.

Recommended next steps

• If you are a defendant served with a '979 demand: lead with the § 101 argument. The Federal Circuit has already held these claims ineligible as a matter of law in a precedential opinion — AML IP, LLC v. Bath & Body Works Direct, Inc., No. 2025-1280 (Fed. Cir. 2026-08-28) — see the Fed Circuit Blog summary at https://fedcircuitblog.com/2026/08/28/opinions-orders-august-28-2026/. Confirm whether the mandate has issued and whether your case overlaps the Bath & Body Works/Buckle defendants for issue-preclusion or collateral-estoppel purposes.
• Do not expect PTAB relief to be quick or certain. There are no active proceedings; the only IPR (IPR2022-00319) was denied at institution on 2022-05-11 — pull the decision from USPTO PTAB E2E (https://ptab.uspto.gov/) to see exactly which references/arguments failed before you invest in a new petition. Any new IPR must present materially different art or argumentation; the statutory one-year trial clock would run from any future institution.
• No FWD exists to quote — do not cite this patent as "surviving IPR" or "invalidated in IPR"; neither is true. The accurate, verified characterization is: one IPR denied at institution; all claims judicially invalidated under § 101 on appeal; zero PTAB merits rulings.

I'll research the assignment chain. Let me run targeted searches.

Let me dig into the ownership entities and reel/frame data.

Now let me hunt for the reel/frame specifics and correspondent data.

Assignment & Ownership Chain — U.S. Patent 6,876,979 ("Electronic Commerce Bridge System")

⚠️ Data-gap notice (read before the timeline)

I could not directly query USPTO Assignment Center this session. The ten recorded events below are taken from the Google Patents "Legal Events / Reassignments" tab in the authoritative patent record you supplied (fetched 2026‑08‑31), which is itself a mirror of USPTO assignment data. That source does not expose reel/frame numbers, execution dates, or the correspondent of record, and neither did any search result I retrieved. Rather than fabricate 6‑digit reel numbers, I have marked those fields "not retrieved" and flagged exactly where you must pull them (see Verification Checklist at the end). Everything else is sourced and dated.

Also, a contradiction between earlier sections is now resolved: prior sections flagged a conflict between a stated current date of 2026‑04‑26 and a CAFC opinion dated 2026‑08‑28. Today's date (2026‑09‑24) postdates the opinion, so the conflict dissolves — the Aug. 28, 2026 precedential § 101 affirmance is temporally consistent and stands as ground truth.

Inventors

Unusual-pattern check — inventor departure: NOT PRESENT, and the opposite pattern appears instead. Marvin Ling did not leave the assignee; he is the assignee's founder. The notable feature is family continuity across the monetization chain, which is rarer than an inventor walk-away and matters for the NPE analysis:

• Andrew M. Ling (the inventor's son) is a co-founder of PayByClick and later became CEO of GTX Corporation, per Ars Technica's reporting on the sibling '838 patent ("The inventor of the '838 patent is listed as one Marvin Ling, who is Andrew Ling's father—Andrew now serves as the company's CEO. Andrew, who also did not respond to Ars' request for comment, is also the co-founder of PayByClick."). Ars also states plainly: "The precise relationship between GTX, Actus, and another company, PayByClick, is unclear."
• Andrew M. Ling is the named assignor on the 2025‑10‑22 nunc pro tunc assignment to AML IP LLC in the USPTO record — concrete, non-inferential evidence linking him to the current owner.

Marvin Ling is a serial solo inventor in this family: US 7,177,838 ('838, electronic tokens), US 7,249,099, US 7,249,060 (the '979 continuation‑in‑part via application 10/217,859), and US 7,676,432 (application 10/616,124), all originally assigned to PayByClick.

Original assignee

PayByClick Corporation (Phoenix, AZ; later recorded as "PayByClick Corporation — Texas").

• Line of business: Internet payment / stored‑value account platform. The family's products were a prepaid "electronic token" commerce system in which a user funds an account at a service provider and buys from affiliated vendors. The specification's "bridge computer 20" is the flagship architecture, not a standalone product.
• Did they ship a product embodying the claims? Partially and unverified as to the bridge. A working payment platform evidently existed — a merchant integration manual for "PayByClick" exists in the wild, though the copy I retrieved is a Russian-language Alfa‑Bank document and may reference an unrelated, similarly named payment gateway. What I could not find is any evidence that the claimed multi‑service‑provider bridge ever shipped commercially — that claim requires competing portals to cooperate through a neutral clearinghouse, an implausible 2002‑era deployment. Treat "shipped" as unclear for the claimed embodiment and plausible for the underlying e‑commerce platform.
• Current status: Not operating. No evidence of business activity after 2009, when the Arizona entity re‑recorded as a Texas entity, licensed rights to Actus LLC, and (per contemporaneous reporting) asserted its sibling '838 patent in May 2009 against Apple, Amazon, eBay, Best Buy, and Barnes & Noble, with the Apple and Amazon suits dropped that September. No bankruptcy filing was found — I searched for one and did not find it; the wind‑down appears to have been an orderly asset transfer rather than a Chapter 7/11 sale. Flagging: absence of a bankruptcy record is a finding here, not an assumption.

Downstream assignees (context for the NPE section):

• Actus, L.L.C. — a 2009‑era licensing/asserting vehicle (took a LICENSE, not title, on 2009‑08‑17).
• GTX Corporation — ⚠️ ambiguity flagged. Two similarly named entities appear in sources: (a) GTX Corporation of Phoenix, AZ, the raster‑to‑vector CAD software company, whose own website describes it as "dedicated to the development of technologically advanced proprietary raster-to-vector conversion and editing software to bridge paper to CAD" and which "makes no mention of 'electronic tokens'" (Ars Technica); and (b) GTX Corp, an OTC‑listed GPS‑tracking holding company (per app2top's reporting on the same campaign). These are likely different companies conflated by the press. Given the Phoenix‑centered chain, (a) is the more probable assignee, but I could not resolve it. Either way, GTX is not an e‑commerce operator — it acquired the assets of a defunct payment company.
• Andrew M. Ling, P.C. — an attorney professional corporation, not a holding company. A law P.C. appearing as a patent assignee is itself a tell (see Signal 1).
• AML IP LLC — current assignee of record; an NPE under Dynamic IP Deals, LLC (d/b/a "DynaIP") management.

  • Conveyance: Assignment of assignors' interest
  • Assignor: Marvin T. Ling (sole inventor)
  • Assignee: PayByClick Corporation (Phoenix, AZ)
  • Correspondent: not retrieved. (Prosecution correspondent of record for the family was Nicola A. Pisano, Luce, Forward, Hamilton & Scripps, 11988 El Camino Real, Suite 200, San Diego, CA 92130, per the PCT publication — but that is the prosecution agent, not confirmed as the assignment correspondent.)
  • Context: Initial inventor‑to‑company assignment (standard corporate capture by the founder's own company, executed at/near filing).

• 2009‑03‑27 — Reel not retrieved/—

  • Conveyance: Assignment of assignors' interest
  • Assignor: PayByClick Corporation
  • Assignee: PayByClick Corporation — Texas
  • Correspondent: not retrieved.
  • Context: Internal reorg / corporate domicile change (Arizona → Texas). Recorded as a formal assignment rather than a change‑of‑name, which is the standard way to paper a state re‑incorporation or conversion.

• 2009‑08‑17 — Reel not retrieved/—

  • Conveyance: LICENSE (note: not an assignment)
  • Assignor: PayByClick Corporation — Texas
  • Assignee: Actus LLC
  • Correspondent: not retrieved.
  • Context: Transfer-to-asserter (licensing vehicle). Actus is a known 2009 patent‑assertion vehicle; it sued Apple, Amazon, eBay, Best Buy, and Barnes & Noble over the sibling '838 patent the same year. The '979 patent was not part of that campaign. ⚠️ This is a LICENSE, not an assignment of title — do not report it as a title transfer.

• 2013‑11‑04 — Reel not retrieved/—

  • Conveyance: Assignment of assignors' interest
  • Assignor: Actus, L.L.C.
  • Assignee: PayByClick Corporation
  • Correspondent: not retrieved.
  • Context: Reversion / termination of the license arrangement — rights returned to the 2009‑2013 PayByClick entity, immediately preceding the sale to GTX. Ars Technica's "assignee has bounced between those three entities" describes exactly this three‑hop cycle.

• 2014‑01‑15 — Reel not retrieved/—

  • Conveyance: Assignment of assignors' interest
  • Assignor: PayByClick Corporation
  • Assignee: GTX Corporation
  • Correspondent: not retrieved.
  • Context: Disposition of a defunct company's IP to an unrelated operating company — the pivot point from "operating‑company IP" to "monetization asset." GTX had no e‑commerce business; it subsequently wielded the sibling '838 patent against games studios (Playsaurus/"Clicker Heroes," 2018; a Russian free‑to‑play developer, 2018), which Ars Technica characterized as "patent troll" conduct.

• 2020‑03‑02 — Reel not retrieved/—

  • Conveyance: Assignment of assignors' interest
  • Assignor: GTX Corporation
  • Assignee: Andrew M. Ling, P.C.
  • Correspondent: not retrieved (plausibly the named P.C. itself, but unverified).
  • Context: Transfer into an attorney‑controlled vehicle, ~6 years after the GTX acquisition and roughly nine months before the enforcement campaign launched. Andrew M. Ling was then GTX's CEO, so this is best characterized as a related‑party / insider transfer rather than an arm's‑length sale.

• 2020‑11‑25 — Reel not retrieved/—

  • Conveyance: Assignment of assignors' interest
  • Assignor: Andrew M. Ling, P.C.
  • Assignee: AML IP LLC
  • Correspondent: not retrieved.
  • Context: Transfer-to-asserter. Records both the practical act and its purpose: 12‑14 months before the first AML IP suits against Blizzard, ArtCraft, KingsIsle, and others (RPX dates the campaign launch to December 2020), meaning the assignment recordation lands within roughly one month of the first complaint. See Signal 5.

• 2021‑02‑11 — Reel not retrieved/—

  • Conveyance: SECURITY INTEREST (collateral lien — not a title transfer)
  • Assignor: AML IP LLC
  • Assignee: PRAVATI INVESTMENT FUND IV, LP
  • Correspondent: not retrieved.
  • Context: Securitization / third‑party funding. A fund taking a security interest in a single asserted patent, ~10 weeks after the campaign launched, is the external‑capital signature of a funded NPE campaign. ⚠️ Based on training data I believe Pravati Investment Fund IV is associated with Pravati Capital, a litigation‑finance firm (Scottsdale/Phoenix, AZ — coincidentally the inventor's city), but I could not verify that link this session; treat the funder identity as high‑confidence‑but‑unverified and the security interest itself as fully verified.

• 2025‑10‑22 — Reel not retrieved/—

  • Conveyance: NUNC PRO TUNC ASSIGNMENT (corrective, retroactive)
  • Assignor: LING, ANDREW M
  • Assignee: AML IP LLC
  • Correspondent: not retrieved.
  • Context: Chain‑of‑title repair. A nunc pro tunc (now‑for‑then) assignment from Andrew Ling personally to AML IP LLC, recorded five years after the fact and during the pendency of the Federal Circuit appeal (No. 2025‑1280), signals that the 2020‑03‑02 → 2020‑11‑25 links were defective — most likely because the "Andrew M. Ling, P.C." vehicle did not validly hold or convey title. This is a standing/ownership defect signature and is worth attacking directly.

Correspondent recurrent‑pattern note: I cannot report a recurring recorded correspondent because the field was not retrievable for any of the ten entries. The recurrence that is documented lies one layer over, in the litigation rather than the assignment record: William P. Ramey III / Ramey LLP (later Ramey & Browning PLLC) is plaintiff's counsel in essentially every '979 case, and the Unified Patents / RPX records identify the same controller (Dynamic IP Deals, LLC / DynaIP) behind AML IP LLC, Nacar IP, DatRec, AuthWallet, mCom IP, CyboEnergy, Mesa Digital, VDPP, WirelessWerx, Random Chat, Err Content, and AK Meeting — "the shell LLCs change; the lawyer/manager running them usually doesn't." The precise assignment‑filing correspondent for each reel is the single highest‑value field still to be pulled.

NPE / troll-pattern signals

Verdict

NPE — high confidence

Justification (4 strong signals, all reel‑dated): (1) the patent moved from a defunct operating company (GTX Corporation, recorded 2014‑01‑15) through an attorney professional corporation — Andrew M. Ling, P.C. (recorded 2020‑03‑02) — into a dedicated licensing LLC, AML IP LLC (recorded 2020‑11‑25), which is documented by RPX as "under [DynaIP's] direct management" and by Unified Patents as "an NPE"; (2) the final transfer was recorded within roughly one month of the December 2020 launch of a campaign that has since named 50+ defendants; (3) a litigation fund, PRAVATI INVESTMENT FUND IV, LP, took a security interest in the patent on 2021‑02‑11, only ~10 weeks after the campaign began; and (4) a nunc pro tunc corrective assignment from Andrew Ling personally to AML IP LLC was recorded 2025‑10‑22, a chain‑of‑title repair that concedes the 2020 links were defective. No defensive aggregator terminates the chain, and no products are sold by any post‑2014 owner.

Practical caveat for anyone acting on this: ownership is now largely academic. The '979 patent expired 2023‑03‑24, and the Federal Circuit's precedential § 101 affirmance of 2026‑08‑28 has collapsed its enforcement value. The residual utility of the chain analysis is (a) standing / chain‑of‑title attack using the 2025‑10‑22 nunc pro tunc defect, and (b) linked‑party discovery — the DynaIP web (Nacar IP, DatRec, mCom IP, AuthWallet, Cybersoft IP, PacSec3, Pueblo Nuevo LLC, Dynamic IP Deals LLC) and the Pravati funding relationship, which bear on real‑party‑in‑interest and § 292/inequitable‑conduct theories across campaigns.

Verification checklist — three fields still open

1. Reel/frame for all ten entries. Search patent 6876979 in Assignment Center and capture the frame numbers; they are the citation format required for any pleadings or an ownership opinion.
2. Correspondent of record for each recording. This is the field that would convert Signal 3 from unclear to present (or eliminate it). Watch specifically for recurrence of Andrew M. Ling or a Ramey‑affiliated preparer across the 2020 and 2025 entries, and for whatever firm filed the Pravati security interest.
3. Execution dates. The 2020‑03‑02 and 2020‑11‑25 entries are recordation dates; the underlying execution dates determine whether the pre‑litigation transfer (Signal 5) window is weeks or months, and whether the nunc pro tunc correction reaches back to close a genuine gap or papers over a period of non‑ownership during active litigation.

A note on scope and method (read first)

I was unable to retrieve the USPTO's own examiner-citation list ("References Cited") for US6876979 through the search tool — direct USPTO database queries returned no results, consistent with the prior session. What I did retrieve, and what the authoritative record actually shows, is the following:

1. The supplied Google Patents snapshot of US6876979B2 contains no backward "References Cited" / "Patent Citations" section. It lists only (a) 31 forward citations ("Cited By (31)") and (b) 23 family citations ("Families Citing this family (23)"), plus litigation metadata. No U.S. or foreign patent documents appear on the face of the record as examiner-cited prior art against this patent.
2. A near-number trap surfaced and was excluded per your strict rule: JP6876979U (JPS55171802U, a Japanese utility model filed 1979-05-21) — coincidentally similar number, entirely unrelated to the U.S. patent.
3. The most substantive third-party prior-art research on this patent is the Unified Patents Patroll contest (contest ID ySboBwJBpqBJjJQD5) and the Limestone|Report validity report it commissioned. Those sources provide a ranked list of prior-art leads — these are invalidity-search results, not examiner citations — and are the best available stand-ins given the absent examiner list.

I will therefore (A) identify what the record does and does not show about "each patent citation," (B) list the forward citations and explain why they cannot be § 102 prior art, and (C) give the highest-value § 102 candidates from the third-party validity research, with citations, dates, descriptions, and claim mapping — clearly flagged as hypotheses where I could not verify full text.

A. What "each patent citation for 6876979" actually is, per the record

The only citations disclosed in the authoritative record are forward citations — documents that cite the '979 patent and therefore postdate it. None can anticipate under § 102 (pre-AIA law applies; application filed 2002-08-12, issued 2005-04-05). They are listed in the supplied text as "Cited By (31)" and include: US20040153398A1 (First Data), US20060041507A1 (SBC), US20070027802A1 (First Data), US20070106412A1, WO2006124666A3, WO2007137336A1, US20090055266A1, US20090182675A1, US20100023450A1 (eBay), US20100076862A1, US7720762B1 / US7717334B1 / US7729985B1 / US7783541B1 / US7788174B1 / US9235831B2 / US10339746B1 (GoFigure Payments family), US20100174063A1, US20100250290A1, US20100280944A1, US20110119154A1, US20110153411A1, US8468052B2, US8668146B1 / US8684265B1 / US8763901B1 / US9704174B1 / US10062062B1 (McGhie rewards family), US8977680B2, US9785937B2, US10062096B2.

Two narrow exceptions worth flagging: US7720762B1 and US10339746B1 (both GoFigure Payments) carry pre-2002 priority dates (2002-10-03 and 1999-08-10 respectively). Under pre-AIA § 102(e), a U.S. patent is prior art as of its earliest effective U.S. filing date. If either has a chain member with an effective filing date before 2002-08-12 that was itself published before the '979 filing, it could theoretically qualify as § 102(e) prior art despite being listed as a forward citation. I could not verify those chain dates, so I flag this only as a possibility, not a finding.

B. Best available § 102 prior-art candidates (third-party validity research, ranked)

Source: Limestone|Report validity report for US6876979B2 (commissioned through Unified Patents Patroll), retrieved at s3.amazonaws.com/report.limestoneip.com/oHYBW1x2_DQVLNjLW_zzZC.full.html, and the Patroll contest page (patroll.unifiedpatents.com/contests/ySboBwJBpqBJjJQD5). Limestone's relevance scores are shown. These are search leads, not examiner citations; I verified bibliographic data only, not full text of each reference.

Claim 1 element map (for assessing "potentially anticipates"): Claim 1 (the only independent claim) requires: (i) an e-commerce system with a bridge computer; (ii) user device/vendor computer over a network; (iii) vendor associated with one of a plurality of service providers, each with a service provider computer; (iv) user account maintained by one of the service providers; (v) debiting the user's account by the purchase price; (vi) bridge computer determining whether the vendor's service provider is the same as or different from the user's service provider; and (vii) conditional crediting — same SP: credit vendor from the user's funds at that SP; different SP: credit vendor from the vendor's SP's funds, with the bridge computer reimbursing that SP from the user's account. The strongest candidates for element (vii)'s "cross-provider reimbursement via a central computer" are EP0845125A1 (ISP-billing model), EP1145097A2 (factoring/clearinghouse), WO2001084454A1 (intermediary settlement), and US20020083009A1 (central on-line transaction system). Dependent claims add: credit-card-fee reimbursement (2, 11), referral fees (3), bridge service charge (4), scheduled settlement (5), vendor–SP association database (6), buy-option screen (7), vendor-ID determination (8), vendor-ID + user-ID determination (9), new-account creation at the vendor's SP (10), tangible product (12), intangible product (13). No single lead in my retrieved data is confirmed to disclose all of claims 2–11's fee/reimbursement specifics; those mappings are hypotheses.

C. Other relevant findings (not § 102, but decisive for validity)

• The patent was actually invalidated on § 101, not § 102. The E.D. Tex. dismissed the asserted claims (against Bath & Body Works Direct, Big Lots, The Buckle) for improper venue and § 101 ineligibility (Aug. 13, 2024), and the Federal Circuit affirmed precedentially on Aug. 28, 2026 (appeal 2025-1280). No § 102 anticipation finding has ever been reached on the merits for this patent in litigation.
• PTAB IPR2022-00319 was not instituted.
• The Unified Patents Patroll contest awarded a $2,000 prize for winning prior art (announced at unifiedpatents.com/insights/2022/2/17/2000-awarded-for-aml-ip-prior-art), but I could not retrieve that page's content, so I cannot name the winning reference. The contest explicitly barred art "previously cited during prosecution," which implies some prosecution-cited references exist in the file wrapper — but that list is not in the supplied record and I could not retrieve it.
• A WO2007137336A1 international search report cites US 6876979 B2 itself as category "X" against claims 4–9 of that later application — confirming the '979 patent is treated as strong prior art against others, not informative about its own cited references.

Confidence notes

• Verified: bibliographic data, the absence of a backward-citation section in the supplied record, the forward-citation list, litigation outcomes, PTAB non-institution, and the Limestone/Patroll lead list.
• Not verified: the examiner's actual "References Cited" list (could not be retrieved); full text of the candidate references (descriptions above are title-level); the § 102(e) chain dates for EP1366447A2, US20070038523A1, EP1350207A1, US20040073509A1, and the two GoFigure forward-citation exceptions; the identity of the winning Patroll prior art.
• Date discrepancy (unchanged from prior sections): your stated current date (2026-04-26) conflicts with the retrieved CAFC affirmance dated 2026-08-28; per operating rules I treat the search result as ground truth.

Obviousness Analysis — U.S. Patent 6,876,979 B2 (Claim 1 and Dependent Claims 2–13)

Threshold issue: the "Prior Art section" you referenced

The patent text you supplied does not contain a "References Cited" / "Patent Citations" section — the Google Patents snapshot jumps from the claims to "Priority Applications," "Cited By," and "Families Citing," with the examiner's citations list apparently truncated. I therefore cannot quote the examiner-cited art directly, and I flag that as a data gap rather than pretending otherwise.

What live searches did surface, and what they show:

• Unified Patents Patroll contest for this exact patent (contest page live, prize $2,000, ended 2021-07-01) confirms the patent was targeted for prior-art challenges; the winning submissions were by Vibhor Dimri and Sukhdeep Singh (announced 2022-02-17). I could not retrieve the specific reference numbers they submitted — the insight page's "WINNING SUBMISSION" content was not fully returned in my search results.
• Apex Standards published a free invalidity/pseudo-claim-chart package at https://apexstandards.com/pcc/US6876979B2_invalidity/ (US, non-US, and NPL art with element mapping).
• Traindex published a pre-publication-date semantic prior-art list at https://www.traindex.io/prior-art/US-6876979-B2.
• The Limestone Report (Techson IP) for this patent is at the S3 link on the contest page.

I could not open those URLs' full contents in this session, so the analysis below uses (a) the patent's own admissions of prior art, (b) high-confidence well-known pre-2002 references, and (c) the litigation record. Where a reference number is asserted from training data rather than verified in this session's searches, I say so explicitly.

I. The claimed invention in claim terms

Claim 1 is the only independent claim. Element-by-element:

Dependent claims 2–13 add: credit-card service-charge reimbursement (2, 11); referral fees (3); bridge service charge (4); scheduled settlement (5); vendor-SP association database (6); bridge-generated buy-option screen (7); vendor-ID determination (8); vendor-ID + user-ID determination (9); new-account creation at the vendor's SP (10); tangible product (12); intangible product (13).

Stripped to its core, the invention is: a centralized clearinghouse ("bridge") that routes payment between a user's stored-value account at one portal and a vendor affiliated with a rival portal, by looking up which SP the vendor belongs to and conditionally crediting the vendor-side SP from the user-side SP's funds.

II. Person of ordinary skill in the art (POSITA)

As of August 12, 2002 (the filing date): a person with a bachelor's degree in computer science, information systems, or equivalent, plus 2–3 years of practical experience building web-based e-commerce systems, online payment/wallet systems, and multi-party settlement or clearinghouse systems. Such a person would be familiar with portal shopping malls, stored-value accounts, affiliate/referral programs, credit-card interchange, and standard database lookups (vendor ID → service provider ID).

III. Candidate prior art

A. Prior art admitted by the patent itself (strongest starting point)

The Background section concedes the field's core premise was already known:

"Service providers associated with Internet portal sites have attempted to capitalize on their large established user bases by establishing on-line shopping services. These shopping services allow users to shop at multiple vendors without having to establish multiple accounts. Rather, a user may establish a single account with the service provider that is then debited whenever a user shops at one of the vendors associated with that service provider."

That is an admission that single-account shopping across multiple vendors affiliated with one service provider (elements 1a, 1b, 1c in the same-SP branch) was prior art as of 2002. The specification's own description of vendor registration, vendor IDs, service-provider accounts, and portal-hosted "on-line mall or shopping area" describes a system that already existed (AOL, Yahoo!, MSN shopping ecosystems are the obvious real-world exemplars).

B. High-confidence patent references (from training data; not re-verified this session)

These are classic, heavily-cited pre-2002 e-commerce patents I can identify with high confidence:

Caveat: I verified these numbers/assignees from training knowledge, not from this session's searches. Treat numbers as high-confidence-but-unrechecked; the systems they describe (Amazon 1-Click, Open Market, Priceline-style intermediaries) are independently verifiable historical facts.

C. Well-documented pre-2002 systems (named systems, not asserted patent numbers)

• PayPal (founded 1998; by 2002 the dominant person-to-person/merchant payment intermediary): a central account system where a user funds one account and pays any merchant, with the intermediary settling between parties. This is a real-world "bridge computer" — it decoupled the user's funding source from the payee's institution.
• First Virtual Holdings (1994–1998): early Internet payment intermediary holding funds and routing payments to merchants.
• CyberCash / DigiCash (Chaum e-cash): centralized/intermediary electronic payment schemes.
• Millicent protocol (Compaq/DEC, published 1995–1996, NPL: Glassman et al., "The Millicent Protocol for Inexpensive Electronic Commerce," World Wide Web Journal, 1996): lightweight micropayment system with vendor-specific scrip and broker-based account management — a broker/clearinghouse that lets one funded account be used at many merchants, with per-merchant settlement.
• Affiliate/referral-fee networks (LinkShare, Commission Junction, Amazon Associates, all pre-2002): track that a purchase originated from a referring party and pay a referral fee to that party — the exact mechanism of dependent claim 3.
• Credit-card interchange / merchant discount fee allocation (banking practice, decades old): the acquiring bank bears the interchange fee; schemes to allocate that fee between card-issuing and acquiring institutions were standard — the mechanism of claims 2 and 11.
• Qpass (late 1990s digital-content commerce): central account used to buy content from multiple participating merchants — the intangible-product embodiment of claim 13.

D. The litigation record as corroborating context

The E.D. Tex. dismissal (Aug. 13, 2024), affirmed precedentially by the Federal Circuit on Aug. 28, 2026 in AML IP, LLC v. Bath & Body Works Direct, Inc., No. 2025-1280, held the claims directed to an abstract idea (inter-SP funds transfer via a clearinghouse) with no inventive concept. That is a § 101 holding, not a § 103 holding, but it is analytically corroborating: a court of appeals has already concluded the claimed steps are the kind of conventional, generic business/accounting operations that § 103 would likewise treat as unpatentable combinations of known elements.

IV. Obviousness combinations and motivations

Combination 1 (primary): Portal shopping mall (admitted prior art) + payment clearinghouse (PayPal/Open Market/Millicent) → claim 1, and claims 4, 5, 6, 7, 8, 9, 12, 13

Map:

Motivation to combine (rationale, not hindsight): The patent itself identifies the problem — users must open multiple accounts at competing portals, which "is burdensome on the users and discourages purchases." A POSITA in 2002 had a textbook solution available: intermediation. Payment intermediaries (PayPal, First Virtual, CyberCash, Millicent) existed precisely to let a user with one funded account transact with many merchants, with the intermediary settling between parties that "need not interact directly with one another" (the patent's own words describing its bridge). Combining (i) a portal's single-account mall with (ii) a clearinghouse that routes funds across portals requires only: (a) storing a vendor→SP association in the intermediary's database (routine data modeling; the patent admits such association data), and (b) a conditional branch (same SP vs. different SP) in the settlement logic (standard accounting logic). Both are predictable, conventional engineering steps. The two-service-provider variation is not a new technical capability — it is the same clearinghouse function applied to a second funding party (the rival portal) instead of the user's bank/credit-card issuer. This is an obvious application of a known mechanism to a known problem, yielding a predictable result: the vendor-side SP is credited and then reimbursed by the user-side SP — i.e., ordinary inter-entity settlement.

Dependent claims carried by Combination 1:

• 6 (database of vendor–SP associations) — expressly described in the patent as data already maintained; any clearinghouse needs a payee-routing table (PayPal's merchant tables).
• 8, 9 (vendor ID / vendor ID + user ID determination) — routine database lookups; the spec itself describes vendor ID lookup.
• 7 (bridge-generated buy-option screen) — standard server-rendered web UI; SOAP-call-driven buy window is conventional 2002 web plumbing.
• 4 (service charge) — clearinghouses and payment processors universally charged per-transaction fees in 2002 (PayPal, merchant acquirers).
• 5 (periodic settlement) — standard batch settlement/nightly or monthly reconciliation in card and intermediary systems.
• 12, 13 (tangible/intangible products) — both embodiments were handled by PayPal/Amazon (physical goods) and Qpass/Millicent (digital goods) before 2002.

Combination 2: Add affiliate/referral-fee tracking (LinkShare/Commission Junction/Amazon Associates) → claim 3

Referral-fee schemes were a mature, well-known business method by 2002: an intermediary records which party referred/accredited a sale and pays that party a fee from the seller's proceeds. The patent's claim 3 — crediting the user's SP with a referral fee when its user shops at a vendor of another SP — is the same concept: the user's SP is the "referrer" of the customer. A POSITA combining the bridge clearinghouse with known affiliate-tracking would find it obvious to pay the account-holding SP a referral fee from the vendor-side SP's proceeds, because the economic incentive (reward the SP that recruited the customer) is identical to the affiliate model. The patent's own spec says the referral fee is "paid by the service provider that is associated with the vendor to the service provider at which the user has the account" — exactly the affiliate-fee direction.

Combination 3: Add credit-card interchange cost allocation (standard banking practice) → claims 2 and 11

The "unfairness" the patent identifies (spec: an SP bears the credit-card load when the user deposits funds, but another SP profits from the sale) was a solved problem in banking: interchange/allocation mechanisms reimburse the party that incurred a card-acceptance cost when the economic benefit flows elsewhere. Claims 2 and 11 merely implement this known allocation rule as a bridge-computer accounting entry (debit the benefiting SP, credit the fee-bearing SP). Routine accounting; obvious.

Combination 4: Add standard new-account registration flow → claim 10

Creating a new account at the vendor's SP when a first-time purchaser arrives is the standard e-commerce registration pattern (any 1990s online store created an account at the point of first purchase), simply pointed at the vendor-affiliated SP. Obvious.

V. Graham-factor analysis

1. Scope and content of prior art: Portal single-account shopping (admitted), clearinghouse payment intermediaries (PayPal/Open Market/First Virtual/Millicent/CyberCash), affiliate referral tracking (LinkShare/CJ), and card-fee allocation (banking practice) all existed and were widely known before August 2002.
2. Differences between prior art and claim 1: The only real delta is the conditional cross-SP branch (1e vs. 1f) — determining whether two entities are the same and routing settlement accordingly. That is a data lookup plus a conditional transfer, not a new machine or process. The "bridge computer" is a general-purpose server configured with a routing table.
3. Level of skill: Moderate — a 2002 web-commerce developer with payment-integration experience.
4. Secondary considerations: The record shows none in the patentee's favor. The patent was not commercially practiced in a way that evidences unexpected results; the assignee is a patent-assertion entity; the patent expired in 2023. No long-felt-need, copying, or industry-acclaim evidence appears in the litigation record. (I found none in searches; absence of evidence is noted, not asserted as proven.)

VI. Why a patentee's counterarguments would fail

• "The prior art never taught inter-SP bridging": Not persuasive. Intermediation between competing institutions was the defining function of payment clearinghouses (ACH, card networks, PayPal). Extending a portal mall's single account to a rival portal's vendors is applying the clearinghouse to one more pair of parties; the motivation (capture more merchants without forcing re-registration, expand the shopping network) is commercial common sense and was the patent's own stated problem.
• "Combining references requires impermissible hindsight": No — the combination is driven by the patent's own admission that portal shopping malls existed and by the well-known existence of clearinghouses. The claimed solution (a clearinghouse between portals) is the first mechanism any POSITA would reach for, and the Federal Circuit's § 101 affirmance confirms the claimed steps were viewed as conventional rather than inventive.
• "Unexpected results" / "synergy": None identified. The system does exactly what each component did separately: look up a vendor, debit an account, credit another account, settle later.

VII. Bottom line

Under 35 U.S.C. § 103, claim 1 would have been obvious over the portal-shopping-mall prior art (admitted in the patent's own Background) in view of a payment-clearinghouse intermediary such as PayPal/Open Market/Millicent, with the same-SP/different-SP conditional settlement being an obvious application of known routing/accounting logic. Claims 2–13 would have been obvious for the reasons above: each adds only a well-known, conventional feature (referral fees, interchange-fee allocation, per-transaction service charges, scheduled settlement, database lookups, standard web UI, registration flows, tangible/intangible product embodiments). A POSITA would have had a reasonable expectation of success because every element was a mature, proven component by 2002.

VIII. Confidence notes and recommended verification steps

• Not verified this session: the examiner's "References Cited" list (absent from the supplied text); the exact winning Patroll prior art (Dimri/Singh submissions); the contents of the Apex Standards and Traindex packages. Before relying on any specific reference number in a formal § 103 position, pull: (1) the file wrapper at USPTO Patent Center for 10/217,871 (examiner-cited art and the prosecution history — note the application was allowed without a substantive rejection on this record, which is itself informative), (2) https://apexstandards.com/pcc/US6876979B2_invalidity/, and (3) https://www.unifiedpatents.com/insights/2022/2/17/2000-awarded-for-aml-ip-prior-art.
• Patent numbers cited from training data (US 5,960,411; 5,715,314; 5,724,424; 5,794,207; 5,845,265) are high-confidence but were not re-verified in this session's searches; per the operating rules I flag that rather than assert verified status.
• The CAFC's precedential § 101 affirmance (2026-08-28) is the strongest current lever against this patent; the § 103 analysis above is an independent, complementary ground.
