US 11044342

I'll search for this specific patent and any related 2026 CAFC docket activity.

Now let me get the actual claim text and confirm the litigation status.

Let me retrieve the full independent claim language for this patent to ground the analysis.

US Patent 11,044,342 B2 — Analyst Summary

Data provenance note / caveat: I do not have direct terminal access to USPTO PatentCenter/PAIR or PACER in this session. The following is compiled from the authoritative full-text you supplied (Google Patents, fetched 2026‑09‑24), plus live public-web results (Justia, Espacenet, Patexia, Unified Patents, Supreme Court docket PDF, Law360/IIPLA reporting). I flag every point where the record is thin or where sources disagree.

⚠️ Similar-number contamination warning: Public results repeatedly blur this patent with numerically adjacent siblings — 11,044,341, 11,044,344, and 11,044,345 (all "System providing faster and more efficient data communication"), and with 11,412,025 / 10,637,968 / 10,582,013, which claim from the same family (some sources list priority as 2009‑10‑07 rather than 2009‑10‑08). I have kept them separate below and did not merge findings.

1. Bibliographic data (patent 11,044,342 specifically)

2. Abstract (verbatim)

"A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine. The IP address of the server in the communication request is transmitted to the acceleration server, which provides a list of agents to use for this IP address. The communication request is sent to the agents. One or more of the agents respond with a list of peers that have previously seen some or all of the content which is the response to this request (after checking whether this data is still valid). The client then downloads the data from these peers in parts and in parallel, thereby speeding up the Web transfer, releasing congestion from the Web by fetching the information from multiple sources, and relieving traffic from Web servers by offloading the data transfers from them to nearby peers."

3. Independent claim — plain-language overview

Claim 1 (method, performed by a "first client device"). Verbatim from the Espacenet claim set for US 11,044,342 B2:

"1. A method for use with a web server that responds to Hypertext Transfer Protocol (HTTP) requests and stores a first content that is identified by a first Uniform Resource Locator (URL), the method by a first client device comprising:
executing, by the first client device, a web browser application or an email application;
establishing a Transmission Control Protocol (TCP) connection with a second server;
receiving, the first content from the web server over an Internet; and
sending the received first content, to the second server over the established TCP connection, in response to the receiving of the first URL."

A parallel rendering of the same claim (as excerpted in the Federal Circuit opinion and reproduced in the cert petition, lettered [a]–[d]) reads: "[a] … [b] establishing a TCP connection with a second server; [c] receiving, the first content from the web server over an Internet; and [d] sending the received first content, to the second server over the established TCP connection, in response to the receiving of the first URL."

In plain language: A user's own device (the "client") is running a browser or email program. That device opens a TCP connection to a second device that is operating as a server. The client retrieves the requested content itself from the origin web server over the Internet, and then — rather than keeping it locally — forwards the fetched content back to that second device over the TCP connection it established. The client is thus conscripted as a data supplier/relay feeding content into the accelerator network so the network (specifically the "agent") can hold and re-serve it.

Claim-construction dispute (important to scope):

• The PTAB construed "client device" = "a communication device that is operating in the role of a client" and "second server" = "a server that is not the client device" (role-based, not hardware-based).
• Bright Data argued the terms are hardware-based (client device = a consumer computer, distinct hardware from a commercial server) and that it acted as its own lexicographer. Both the Board and the Federal Circuit rejected that (see §5).

Uncertainty I must flag: I was unable to authoritatively confirm the complete set of independent claims of this patent in this session. Claim 1 is the only independent claim for which I retrieved full text. For context, the PTAB petition in IPR2022‑00103 challenged claims 1, 2, 6–11, 13, 15, 16, 18–23 of the '342 patent, which is consistent with claim 1 being the principal independent claim, but I cannot certify whether one or more additional independent (e.g., system/apparatus) claims exist. Dependent claims 2–4 that I did see recite MAC-address/hostname registration with the second server at start-up and reporting an application version number — matching the specification's "acceleration system initializer" description.

4. Specification gist (beyond the claims)

The disclosure describes a network of communication devices each running the same acceleration software, toggling between client, peer, and agent roles; an acceleration server holding an IP-indexed database of online agents; HTTP responses split into fixed-size chunks (16 KB example) each identified by a checksum used as a lookup key; a per-URL cache database indexed by URL and by checksum; validity testing via HTTP freshness headers and conditional requests (RFC 2616); and an alternative embodiment applying the same chunk/checksum/peer scheme at the TCP/IP layer (FIGS. 14–15). The Summary of the Invention describes the four-element architecture (client, agent assigned to a data server that tracks which clients have received responses, peer storing portions of data, and acceleration server deciding agent assignment).

5. Litigation / PTAB / appellate posture (verified 2026 events)

• PTAB: Code200, UAB et al. v. Bright Data Ltd., IPR2022‑00103, petition filed 2021‑10‑29, instituted 2022‑06‑01, Final Written Decision 2023‑05‑30 invalidating the challenged claims in view of Reiter, "Crowds: Anonymity for Web Transactions" (ACM TOIS, Nov. 1998), plus obviousness analysis on secondary considerations. Panel: Giannetti, McShane, Cass. (https://services.patexia.com/lawsuits/Code200-UAB-et-al-v-Bright-Data-Ltd-id-[156285](/patent/156285))
• CAFC: consolidated appeals with 23‑2144 as the lead case, together with 23‑2145, 23‑2146, 23‑2147, 23‑2414, 23‑2415, 23‑2442, and 23‑2443; judgment entered 2025‑08‑01, AFFIRMED (non-precedential). The court agreed with the Board's role-based constructions of "client device" and "second server," rejected Bright Data's lexicography argument, and upheld invalidity over Crowds. (Petition Appendix, https://www.supremecourt.gov/DocketPDF/25/25-779/[390526](/patent/390526)/20251230140702018_Bright%20Data%20Ltd%20v%20Code200%20UAB%20-%20Petition%20Volume%201%20of%202.pdf)
• En banc rehearing petition filed ~2025‑08‑29 by Cherian LLP (Robert M. Harkins Jr.), arguing the panel ignored IPR-proceeding prosecution disclaimers. (https://fedcircuitblog.com/wp-content/uploads/2025/09/Petition-Bright.pdf)
• Supreme Court: No. 25‑779, cert petition filed 2025‑12‑30; distributed for the 2026‑02‑20 conference; petition DENIED 2026‑02‑23. Question presented: whether a patentee's disclaimers during PTO proceedings (including IPR) preclude broader claim construction. (https://relistwatch.com/case/25-779)
• Reported 2026 confirmation: SCOTUS declined review of the Federal Circuit decision invalidating claims of four Bright Data patents — 10,257,319; 10,484,510; 11,044,342; 11,044,344 — in the ~$7.5M E.D. Tex. dispute (Law360, 2026‑02‑23; IIPLA, 2026‑03‑02). Note: some secondary outlets (PatSnap) mis-state the patent number as 11,044,344/11,044,342 interchangeably — treat those as unreliable on the number.

6. Direct answer on "CAFC 2026 dockets"

I found no 2026 Federal Circuit docket activity on US 11,044,342. The Federal Circuit phase concluded with the 2025‑08‑01 affirmance in the consolidated appeal led by 23‑2144; the only 2026 event tracing to this patent is the Supreme Court's 2026‑02‑23 denial of certiorari in No. 25‑779, which leaves the invalidity judgment in place. I could not independently verify whether a Rule 36/mandate date or any 2026 CAFC miscellaneous proceeding exists; if you need a certified check, that requires a PACER/CM-ECF query on the 23‑2144 consolidated docket itself.

7. Bottom line

US 11,044,342 (Bright Data / Web Spark, inventors Shribman & Vilenski, filed 2019‑10‑13 as a continuation in the 2009‑10‑08 priority family, issued 2021‑06‑22) claims a client device that fetches web content for itself and then relays that fetched content over a TCP connection to a second server operating in a server role. The challenged claims were held unpatentable by the PTAB (IPR2022‑00103, FWD 2023‑05‑30) over the Crowds reference, the Federal Circuit affirmed on 2025‑08‑01, and the Supreme Court denied certiorari on 2026‑02‑23 — so the claims are, as of today's date, cancelled. The principal residual uncertainty in this summary is the complete enumeration of independent claims, which I could not confirm from authoritative sources in this session.

I'll research litigation involving US Patent 11,044,342. Let me run several searches.

Let me dig deeper into the specific cases involving this patent.

Let me confirm additional details on the $7.5M case and any district court assertion of this specific patent.

Litigation Involving U.S. Patent No. 11,044,342

Bottom line

U.S. Patent No. 11,044,342 ("System providing faster and more efficient data communication," Bright Data Ltd.) has not been asserted in any U.S. district court infringement action. Bright Data itself represented on appeal that "[t]he '342 and '344 Patents have not been asserted in any district court litigation," and the PTAB's Final Written Decision in IPR2022-00103 records that "[t]he parties do not... identify any district court cases that involve the '342 patent" (see Bright Data's CAFC appellant brief, Bright Data Ltd. v. Code200, UAB, Nos. 2023-2144 et al.).

The '342 patent has been the subject of a contested administrative validity proceeding (IPR) at the PTAB and of the resulting appeals. Those are summarized below. If by "litigation" you mean district court infringement suits, the answer is none known as to this patent.

1. IPR2022-00103 (PTAB — the lead proceeding on the '342 patent)

The Board found the claims anticipated and/or obvious over prior art including Crowds (Reiter, "Crowds: Anonymity for Web Transactions," ACM TISSEC, Nov. 1998), and rejected Bright Data's evidence of secondary considerations for lack of nexus.

Sources: Final Written Decision (public version) at Docket Alarm, Code200, UAB v. Bright Data Ltd., IPR2022-00103; Patexia case summary (case no. IPR2022-00103, filed Oct. 29, 2021, decision May 30, 2023).

2. Federal Circuit appeal — Nos. 2023-2144 et al. (consolidated)

The Google Patents family record you provided lists Federal Circuit cases 23-2443, 23-2442, and 23-2144; these are all part of this single consolidated appeal (23-2144 is the lead).

Sources: Bright Data Ltd. v. Code200, UAB, No. 23-2144 (Fed. Cir. Aug. 1, 2025) (CourtListener opinion 10646198); Federal Circuit appellant brief (Feb. 6, 2024); Docket Alarm / PTAB exhibit copy of the opinion.

3. U.S. Supreme Court — No. 25-779

With the denial, the Federal Circuit's affirmance of unpatentability of the '342 patent (and the three related patents) became final.

Sources: supremecourt.gov docket PDF for No. 25-779 (petition volumes); Law360 / IIPLA report "Justices Won't Eye Axed Bright Data Patents From $7.5M Case" (Feb. 23, 2026); Oxylabs blog update (Feb. 23, 2026); Google Patents family-litigation entry for Supreme Court case 25-779.

4. Possibly related 2024 PTAB petition — verify independently

A PTAB exhibit footer in the record reads: "Oxylabs, UAB v. Bright Data Ltd. — IPR2024-00126 — Oxylabs EX1033," which suggests Oxylabs, UAB filed a second IPR against the '342 patent in 2024. I could not confirm the institution status, claims challenged, or outcome of IPR2024-00126 from the sources I was able to retrieve. Treat this as unverified and check the USPTO PTAB docket directly.

5. Nearby litigation that did NOT assert the '342 patent (for context only)

These are frequently conflated with the '342 patent in press coverage because they involve the same patent family (Shribman/Vilenski priority, Oct. 8, 2009) and overlapping defendants. None of them asserted the '342 patent:

Sources: Jury Verdict Form, No. 2:19-cv-00395-JRG (Nov. 5, 2021); Teso stay order (Feb. 28, 2023); BusinessWire / ACCESSWIRE releases (Nov. 10, 2021); PTAB petition mandatory-notice tables listing the related district court cases.

Caveats and verification notes

1. I was unable to directly query the Unified Patents litigation portal or PACER (search tool step limit reached). The Google Patents "family litigation" block you supplied itself lists only IPR2022-00103, Supreme Court 25-779, and Federal Circuit 23-2443 / 23-2442 / 23-2144 — which is consistent with my finding that there is no district-court case on the '342 patent.
2. Third-party analytics sites (e.g., Patsnap) describe "Bright Data, Ltd. v. Code 200, UAB" as litigation over the '342 patent. That characterization is imprecise: case 23-2144 is an appeal from a PTAB IPR, not a district court action. I have not treated those summaries as establishing district court litigation.
3. I did not auto-correct any identifiers. Note the inconsistency in the primary sources themselves: the plaintiff appears as "Luminati Networks Ltd.," "Bright Data Networks Ltd.," and "Bright Data Ltd." across different documents; and the Google Patents classification/metadata contains apparent transcription errors (e.g., "processor 52," "driver 212"). These are reported as they appear.
4. Net effect: as of the current date, every challenged claim of the '342 patent has been held unpatentable, the Federal Circuit affirmed, and the Supreme Court denied review. If your interest is enforcement exposure, the '342 patent is effectively invalidated, and any pending district court matters involving it would be expected to be resolved on that basis.

I'll research the PTAB proceedings on US 11044342, starting with the IPR referenced in the patent's litigation metadata.

Let me dig into the IPR2022-00103 Final Written Decision specifics and the Federal Circuit appeal.

I have strong primary-source results. Let me confirm whether any other AIA proceeding targeted the '342 and nail down the Supreme Court cert status.

Source-integrity note before the substance

The structured "PTAB proceedings on file" block states the USPTO ODP API returns no AIA trial proceedings for US 11,044,342. That is contradicted by the record. The patent's own Google Patents litigation metadata lists a PTAB case IPR2022-00103 (Final Written Decision), and the full FWD, the Federal Circuit opinion addressing it, and the resulting Supreme Court petition are all publicly available. I therefore treat the ODP block as stale/incomplete and report the proceeding below, grounded in the FWD text, the Federal Circuit opinion, and the certiorari record. I found no evidence of any second petition directed to the '342 (instituted or denied).

Proceedings overview

There is one AIA trial proceeding on US 11,044,342 — IPR2022-00103 — and it is terminal: all 17 challenged claims were held unpatentable, the Federal Circuit affirmed, and the Supreme Court denied certiorari. Defensive posture for a defendant today: claims 1, 2, 6–11, 13, 15, 16, and 18–23 are canceled — any demand letter or complaint built on claim 1 (the sole method claim examined in the FWD) is a dead letter. Only claims 3–5, 12, 14, 17, and 24 were never tested; they are narrow dependents and cannot rescue an infringement theory anchored on canceled claim 1.

IPR2022-00103 — Code200, UAB; Teso LT, UAB; Metacluster LT, UAB; Oxysales, UAB v. Bright Data Ltd.

• Type: Inter Partes Review (35 U.S.C. §§ 311–319)

• Filed: 2021-10-29 (petition); Institution decision 2022-06-01 (Paper 7). (Note: the patent's Google Patents metadata references this as an "IPR2022-00103 filed" event; the petition filing date comes from the PTAB docket summary.)

• Status: Final Written Decision — all challenged claims unpatentable ("JUDGMENT Final Written Decision Determining All Challenged Claims Unpatentable Granting Motions to Seal, 35 U.S.C. § 318(a); 37 C.F.R. § 42.14"). FWD entered 2023-05-30; public version (Paper 37) entered 2023-06-23. Post-appeal: Affirmed (Fed. Cir. 2025-08-01); certiorari denied (S. Ct. No. 25-779).

• Judge panel: Administrative Patent Judges Thomas L. Giannetti (opinion author), Sheila F. McShane, Russell E. Cass. Oral hearing held 2023-03-14.

• Petition grounds (as instituted): pre-AIA §§ 102/103 (the '342 claims priority to Provisional App. No. 61/249,624, filed 2009-10-08, so pre-AIA law applies):

  • Claims 1, 2, 6, 7, 15, 16, 18–23 — § 102(b) — Crowds (Reiter & Rubin, Crowds: Anonymity for Web Transactions, ACM TISSEC, Nov. 1998)
  • Claims 1, 2, 6, 7, 15, 16, 18–23 — § 103(a) — Crowds
  • Claims 8, 9 — § 103(a) — Crowds + RFC 1122
  • Claims 10, 11, 13 — § 103(a) — Crowds + RFC 2616
  • Total challenged: 1, 2, 6–11, 13, 15, 16, 18–23 (17 claims).

• Institution decision: Instituted as to all challenged claims and all grounds — "we determine that Petitioner has established a reasonable likelihood that it would prevail with respect to at least one claim. We therefore institute inter partes review as to all of the challenged claims of the '342 patent and all of the asserted grounds of unpatentability in the Petition." The panel rejected Bright Data's § 325(d) argument, finding Crowds was never the basis of rejection in the '342 prosecution and was more material than the Fang/Zaid combination the examiner had considered.

• Claim construction (the losing issue for the patent owner): the Board construed "client device" as "a communication device that is operating in the role of a client" and "second server" as "a server that is not the client device" — i.e., role-based, not hardware-based. It rejected Bright Data's proposed "consumer computer" / commercial-server constructions.

• Final Written Decision: All challenged claims held unpatentable. The order reads verbatim:

  "ORDERED that claims 1, 2, 6-11, 13, 15, 16, and 18-23 of U.S. Patent No. 11,044,342 B2 have been shown to be unpatentable[.]"

  On the disputed dependents, the panel relied on a POSA's motivation to cache content in Crowds (claim 10), to send conditional requests with a cache validator per RFC 2616 (claim 11), and to download and install the jondo software application (claim 13). Independent claim 1 fell to Crowds. Bright Data's secondary-considerations evidence (commercial success of its residential proxy service, long-felt need, copying, industry praise) was rejected for lack of nexus under Fox Factory v. SRAM — because the claims do not recite residential proxies, residential consumer computers, or residential IP addresses.

• Settlement / termination: None. This proceeding ran to a merits FWD; there is no record of settlement. (Settlement activity in this family occurred in different proceedings — e.g., NetNut was terminated from IPR2021-01492 in May 2022 — not in IPR2022-00103.)

• Appeal: Yes — Federal Circuit No. 2023-2144, one of eight consolidated appeals (2023-2144, -2145, -2146, -2147, -2414, -2415, -2442, -2443). Issues: (1) construction of "client device"; (2) construction of "second server"; (3) unpatentability over Crowds, Border, MorphMix and/or Plamondon; (4) remand on nexus/secondary considerations. Panel: Judges Hughes, Cunningham, and Stark (Stark authored); nonprecedential. Disposition 2025-08-01: AFFIRMED — "We disagree and affirm the Board," and "We agree with the Board's constructions of 'client device' and 'second server.'" Bright Data then filed a petition for certiorari (S. Ct. No. 25-779) raising an "asymmetrical claim construction"/prosecution-disclaimer theory; reported as denied in early 2026. (Treat the denial as reported/from the docket; confirm on the Supreme Court docket page for 25-779 before relying on it in a brief.)

• Defensive value: Decisive for a defendant. The claims you are most likely to be accused of infringing — claim 1 and its dependents — are canceled. A demand letter or complaint citing US 11,044,342 claim 1 is asserting a claim that no longer exists; the correct response is a § 282 invalidity defense plus the FWD, not a license negotiation. Even against a non-petitioner, cancellation is in rem — the canceled claims cannot be asserted against anyone.

Strategic summary

Claim status (24 claims total). Canceled (challenged and held unpatentable, affirmed): 1, 2, 6, 7, 8, 9, 10, 11, 13, 15, 16, 18, 19, 20, 21, 22, 23. Untested (never challenged, not addressed by the FWD): 3, 4, 5, 12, 14, 17, 24. Do not overread the untested set as "surviving" claims of value: they are dependents whose base claims were canceled, so they are (a) narrow, and (b) exposed to the same Crowds/RFC prior art under the Board's now-affirmed role-based constructions. The FWD did not address claims 3–5, 12, 14, 17, or 24, and I do not claim it did.

Estoppel landscape. § 315(e)(2) estoppel runs against Code200, Teso LT, Metacluster LT, Oxysales (and Coretech LT, named as a real party-in-interest in the sibling '510 proceedings) and their privies. In any later civil action they are barred from raising grounds they raised or reasonably could have raised — i.e., Crowds anticipation and the Crowds+RFC 1122 / Crowds+RFC 2616 obviousness combinations. That estoppel is largely academic here because the claims are already canceled. For a new defendant not in privity with that group, no § 315(e)(2) estoppel attaches, but you also need no IPR: the canceled claims are gone patent-wide, and the untested dependents can still be attacked with the exact same Crowds-based art that prevailed in IPR2022-00103. The only realistic ground you would not be able to recycle is art that a prior petitioner already litigated — and that art is no longer needed.

Pattern signals. The challenger group is commercial competitors, not a defensive aggregator — the Code200/Teso(Metacluster/Oxylabs)/Oxysales/Coretech group plus The Data Company Technologies and Major Data filed a coordinated wave of sister IPRs against the sibling patents ('319 = IPR2021-01492; '510 = IPR2021-01493; plus IPR2022-00135, -00138, -00353, -00915, -00916), and IPR2022-00861/-00862 were joined to the '319/'510 proceedings. No Unified Patents (or similar aggregator) petition appears in the chain — the "Unified Patents PTAB Data" reference on Google Patents is a data-licensing attribution, not a filing. Bright Data litigated aggressively: it pursued eight consolidated Federal Circuit appeals and a cert petition. Bottom line: this is a patent whose lead claims were invalidated once and never rescued on appeal, in a family where the patent owner's role-based claim-construction position lost at both the Board and the Circuit.

Recommended next steps

• If the demand letter/complaint cites claim 1, 2, 6–11, 13, 15, 16, or 18–23: cite the FWD disposition and quote it — "ORDERED that claims 1, 2, 6-11, 13, 15, 16, and 18-23 of U.S. Patent No. 11,044,342 B2 have been shown to be unpatentable." The public FWD is available on PTAB E2E and mirrors are posted at bannerwitcoff.com (IPR2022-00103 filings) and docketalarm. Link the Federal Circuit opinion at CourtListener: https://www.courtlistener.com/opinion/[10646198](/patent/10646198)/bright-data-ltd-v-code200-uab/ (and the Justia PDF of No. 2023-2144, decided 2025-08-01). Confirm the final certificate of cancellation in Patent Center (see the caveat below).
• If a letter cites only claims 3–5, 12, 14, 17, or 24: flag that the FWD did not reach those claims, then attack them with the same Crowds-based §§ 102/103 grounds that prevailed in IPR2022-00103 — the Board's role-based constructions of "client device" and "second server" were affirmed, so the prior-art mapping transfers directly.
• No active proceedings are pending on the '342, so there are no institution deadlines, hearing dates, or statutory FWD milestones to track. The only live question is the ministerial one of when the PTAB/Patent Center reflects the cancellation certificate.
• Do not assume ODP silence means no PTAB history. For this patent, ODP returned nothing while a fully litigated, appealed, and cert-denied IPR exists. Verify any patent's PTAB history against PTAB E2E / PTAB Decisions and the Federal Circuit docket, not the ODP ingest alone.

Caveat on current status. Google Patents still displays US 11,044,342 with legal status "Active" and "Anticipated expiration 2030-07-14." That is almost certainly a database lag: the challenged claims were held unpatentable and the affirmance became final. Before representing to a court or a counterparty that the claims are formally canceled, confirm the USPTO cancellation certificate in Patent Center; do not rely on the Google Patents status field. I did not independently retrieve the certificate, so I flag it as the one item to verify rather than assert it.

I'll research the assignment chain and litigation history for US 11044342 before drafting.

Source limitation up front: I could retrieve the events of the chain (Google Patents legal‑events block) but not the underlying USPTO reel/frame numbers, execution dates, or the correspondent of record. Those fields are not exposed by the sources I could reach; they must be pulled directly from the Assignment Center record for this patent. Nothing below invents them. See USPTO Assignment Center / Assignment Search.

Inventors

• The '342 front‑page inventor data matches sibling patents in the family, e.g. US 10,523,788 B2 ("WEB SPARK LTD., Netanya (IL)"; inventors "Derry Shribman, Tel Aviv (IL); Ofer Vilenski, Moshav Hadar Am (IL)").
• Employer at filing is not determinable from the assignment/face records. What is documented is that the two inventors are the recurring sole inventive pair across the entire Web Spark Ltd portfolio (14 US filings, both inventors named on all of them), and they are the principals of the Luminati/Bright Data enterprise.
• Unusual pattern — inverse of the fire‑sale tell: the classic red flag is "all inventors depart the original assignee within 12 months of filing." Here the opposite occurred. Both inventors remained principals of the acquiring company throughout: Web Spark → Luminati → Bright Data. The 2019 confirmatory assignment from the individuals (Shribman; Vilenski) to Web Spark Ltd was recorded the same day the '342 continuation was filed, i.e. the inventors' personal rights were being consolidated into a holding company at the same moment the new application was filed — a portfolio‑assembly step, not a departure.

Original assignee

Two answers, because they differ by reference point:

• As printed / reported on the issued patent: Bright Data Ltd. Google Patents bibliographic data lists "Original Assignee: Bright Data Ltd" for US 11,044,342. Because the change‑of‑name recordation to Bright Data is dated 2021‑03‑31 — roughly three months before the 2021‑06‑22 grant — the front page plausibly prints the renamed entity. (I was not able to view the printed face of the '342 itself; sibling US 10,523,788, which issued 2019‑12‑31, still prints "WEB SPARK LTD." — so the face text should be confirmed against the granted copy.)
• As the earliest recorded owner: Web Spark Ltd. (Netanya, IL) — a 14‑patent US holding vehicle whose only named inventors are Shribman and Vilenski.

Primary line of business: The practising entity behind the chain is Luminati Networks Ltd → Bright Data Ltd, an Israeli web‑data‑collection company. Luminati has offered its Residential Proxy Network since 2014; the company publicly states "Luminati permits its business customers to utilize its residential proxy network to gather data over the Internet using residential proxy devices." It rebranded Luminati → Bright Data in 2021.

Did they ship a product embodying the claims? Yes, on the record:

• Bright Data maintains a patent‑marking page expressly listing U.S. 11,044,342 (https://brightdata.es/patent-marking).
• In its infringement complaints the company pleads "Luminati practices the Asserted Patents" and claims lost profits on Data Center and static‑residential proxy services.

Current status: Operating, privately held. Current assignees of record on Google Patents are listed as Web Spark Ltd and Bright Data Ltd. Note the commercial outcome for this patent: claims 1, 2, 6–11, 13, 15, 16 and 18–23 were held unpatentable in IPR2022‑00103 (Final Written Decision, 2023‑05‑30), the Federal Circuit affirmed in Bright Data Ltd. v. Code 200, UAB, No. 23‑2144 (2025‑08‑01), and the Supreme Court denied certiorari (No. 25‑779, ~2026‑03).

Assignment timeline

Three events appear in the public legal‑events record for this patent. All three are recorded; execution dates and reel/frame are not retrievable from the sources I could access and are shown as unknown rather than guessed.

• executed: not of record / recorded 2019‑10‑13 — Reel see Assignment Center (not retrievable here)

  • Conveyance: Assignment
  • Assignor: Derry Shribman; Ofer Vilenski (individuals)
  • Assignee: Web Spark Ltd. (Netanya, IL)
  • Correspondent: not retrievable from the sources available — I can neither confirm nor deny a recurring correspondent. This is the single most important field to pull from the Assignment Center record (see note below).
  • Context: consolidation/assembly — the inventors' personal rights moved into the family holding company, recorded the same day the '342 continuation was filed (2019‑10‑13).

• executed: not of record / recorded 2019‑12‑05 — Reel see Assignment Center (not retrievable here)

  • Conveyance: Assignment
  • Assignor: Web Spark Ltd.
  • Assignee: Luminati Networks Ltd.
  • Correspondent: not retrievable — compare to the 2019‑10‑13 entry above; if the same correspondent appears on both, that is the repeat‑correspondent signal (see §3 below).
  • Context: internal reorganisation — intra‑family transfer from holding vehicle to the operating entity, ~2 months after the inventors' assignment.

• executed: not of record / recorded 2021‑03‑31 — Reel see Assignment Center (not retrievable here)

  • Conveyance: Change of Name
  • Assignor: Luminati Networks Ltd.
  • Assignee: Bright Data Ltd.
  • Correspondent: not retrievable — a change‑of‑name filing is normally handled by the same counsel that handled the prior assignments; look for correspondent continuity across all three entries.
  • Context: change of name only — no change in legal ownership. Independently corroborated: in Luminati Networks Ltd. v. code200, UAB, No. 2:19‑cv‑00396 (E.D. Tex.), the plaintiff's unopposed motion to change the case caption to reflect its name change was granted 2021‑03‑30 — one day before this recordation.

Note on the correspondent field. You asked me to treat this as the highest‑value tell. I could not retrieve it, and I will not synthesise an attorney or firm name. To close the gap, pull the three recordations above in the Assignment Center and read the "Correspondent" line on each. If the same attorney/firm appears on all three (2019‑10‑13, 2019‑12‑05, 2021‑03‑31), that is a genuine repeat‑correspondent finding; if it also matches the correspondent on the Shribman/Vilenski filings for US 10,523,788, US 10,257,319, US 10,484,510 and US 11,044,344, it indicates a single firm running the entire family's paper chain.

NPE / troll-pattern signals

1. Shell-entity transfer — NOT PRESENT (weak indicator only).
The chain does contain a holding‑type vehicle: Web Spark Ltd., whose US portfolio is 14 filings, all naming only Shribman and Vilenski. That superficially fits a holding company, but the specific tells are absent or contradicted: (a) the chain does not terminate at Web Spark — it continues to Luminati Networks Ltd (recorded 2019‑12‑05), an operating company with a product in commerce; (b) Luminati/Bright Data publicly marks US 11,044,342 on its patent‑marking page and pleads that it practices the patents; (c) no registered‑agent service address or single‑purpose LLC is evidenced in anything I could retrieve. Call: not present, with the caveat that Web Spark's corporate address/registered agent was not verifiable here.

2. Known asserter in the chain — NOT PRESENT (with a frequency caveat).
Neither Web Spark Ltd, Luminati Networks Ltd, nor Bright Data Ltd appears on the standard NPE rosters (Acacia, Marathon, Intellectual Ventures, IPNav, Wi‑LAN, Mosaid/Conversant, Vringo, Pendrell, Innovatio, MPHJ, Lumen View, Round Rock, Document Generation, Spangenberg entities). The chain terminates at an operating company that sues actual competitors — Teso LT, Code200, Oxylabs, metacluster lt, oxysales, NetNut, Tefincom/NordVPN, BIScience/GeoSurf. That is operating‑company assertion, not NPE assertion. Caveat: it is a high‑frequency plaintiff in the proxy industry, and its enforcement activity is the reason the patent sits in multiple PTAB files.

3. Repeat correspondent across the chain — UNCLEAR / NOT RETRIEVABLE.
I could not obtain the correspondent of record for any of the three recordations. This signal is therefore not assessable on the evidence I hold. It should be the first thing checked in the Assignment Center, because all three links (2019‑10‑13, 2019‑12‑05, 2021‑03‑31) occurred inside a ~17‑month window and would ordinarily have been handled by one firm.

4. Cascading transfers — NOT PRESENT.
Two recorded links separate Web Spark from Bright Data: 2019‑10‑13 → 2019‑12‑05 (~2 months) and 2019‑12‑05 → 2021‑03‑31 (~16 months). Only the first is a genuine ownership transfer; the second is a Change of Name, which conveys no interest. Two assignees, one of which is a renamed version of the other, is not a chained‑LLC cascade. No evidence of shared registered‑agent addresses was obtainable.

5. Pre-litigation transfer — NOT PRESENT as to this patent.
The '342 patent was never asserted in district court. The PTAB institution decision in IPR2022‑00103 expressly records that "the parties do not… identify any district court cases that involve the '342 patent." The nearest executed document is the 2021‑03‑31 change‑of‑name recordation, which follows the 2021‑03‑30 caption change in 2:19‑cv‑00396 and precedes issuance — it is a name‑change housekeeping step, not a standing/venue arrangement. Family context only: sibling patents ('319, '510, '511, '968, '614) were asserted in E.D. Tex.

6. Bankruptcy fire-sale — NOT PRESENT. No Chapter 7/11 proceeding involving Web Spark, Luminati, or Bright Data appears in any source retrieved.

7. Privateering — NOT PRESENT. Privateering requires an operating company to hand patents to an NPE that asserts on its behalf. Here the operating company (Luminati/Bright Data) is itself the plaintiff of record — e.g. Luminati Networks Ltd. v. Teso LT, UAB, No. 2:19‑cv‑395, and Bright Data Ltd. v. code200, UAB, No. 2:19‑cv‑396 — and the entity pleads that it practices the claims. The rights never left the operating group.

8. Defensive aggregator (anti-NPE) — NOT PRESENT. The chain terminates at Bright Data Ltd, an operating asserter, not at RPX, AST, LOT Network, Unified Patents, or OIN. Note for completeness: the patent has been effectively neutralised by other means — IPR2022‑00103 (petitioners Code200, UAB; Teso LT, UAB; Metacluster LT, UAB; Oxysales, UAB) found claims 1, 2, 6–11, 13, 15, 16 and 18–23 unpatentable (FWD 2023‑05‑30), affirmed at 23‑2144 (2025‑08‑01), cert denied (No. 25‑779, ~2026‑03). That is invalidation, not defensive acquisition.

Verdict

Operating-company assertion.

Bright Data Ltd is the current owner of record, reached by two recorded steps — inventors Shribman and Vilenski to Web Spark Ltd (recorded 2019‑10‑13), then Web Spark Ltd to Luminati Networks Ltd (recorded 2019‑12‑05), then a change‑of‑name only to Bright Data Ltd (recorded 2021‑03‑31). Every non‑NPE signal checks out the same way: the ultimate owner is an operating proxy‑network company that marks US 11,044,342 on its patent‑marking page, pleads that it "practices the Asserted Patents," and has sued direct competitors (Teso/Code200/Oxylabs/NetNut) in E.D. Tex. rather than licensing against strangers. No shell‑entity terminus, no named NPE assignee, no bankruptcy, no privateering, and no defensive aggregator appear anywhere in the chain — the only genuine shell‑adjacent fact is that the intermediate Web Spark Ltd holds 14 patents with no other named inventors, which without product or registered‑agent evidence is a name‑shape observation rather than a finding.

Two honest caveats drive the residual uncertainty: (i) reel/frame and correspondent of record were not retrievable, so signal 3 is genuinely unevaluated rather than negatived; and (ii) the patent's asserted claims have been invalidated, so its practical status is "operating‑company patent that lost on validity," not an active licensing asset.

I'll research US patent 11044342 and its cited prior art references.

Let me get the detailed prior art citations from the patent's front page.

Let me search for the specific cited references listed on the patent's front page.

I was unable to complete all planned verification searches (tool step limit reached), so I'll give you a carefully grounded answer that separates confirmed facts from items I could not verify, and I will not fabricate citations.

1. Patent identification (confirmed)

Claim 1 (as it appears in the searchable record) recites a method, by a first client device, for use with an HTTP web server storing first content identified by a first URL, comprising: executing a web browser or email application; establishing a TCP connection with a second server; receiving the first content from the web server over the Internet; and sending the received first content to the second server over the established TCP connection, in response to receiving the first URL.

2. Important limitation on the "citations" question

The authoritative full text you provided (from Google Patents) does not include the patent's front-page "(56) References Cited" / "U.S. Patent Documents" block, and my searches did not return the actual reference list for US 11,044,342. Several search results that looked like they might be the citation list actually belonged to different patents — e.g., US 11,344,413, US 10,637,968, US 10,582,013, US 11,044,345, and foreign-family documents — not to US 11,044,342. I am therefore not able to give you a verbatim "each patent citation for 11044342" list, and I will not invent one.

3. What I did confirm as cited in the record

• "The BitTorrent Protocol Specification" (website: bittorrent.org) — This non-patent literature reference appeared in the Justia record for patent 11044342 (URL surfaced in the search result title). It is the conventional BitTorrent spec describing chunked files, pieces split from content, and swarm-style peer sharing. It is relevant background art for the peer/chunk aspects, though claim 1 (TCP relay of received content to a second server) is not a classic BitTorrent feature.

I could not independently confirm the remaining listed references, so I will not attribute any specific US patent number to this patent's front page.

4. Verified related matters (not prior art, but relevant context)

• PTAB IPR2022-00103, Code200, UAB et al. v. Bright Data Ltd. — Filed 2021-10-29; instituted 2022-06-01; Final Written Decision 2023-05-30. Challenged and invalidated claims 1, 2, 6, 7, 8, 9, 10, 11, 13, 15, 16, 18, 19, 20, 21, 22, 23. Board panel: Giannetti (author), McShane, Cass.
• CAFC appeals 23-2144, 23-2442, 23-2443 and a Supreme Court filing (25-779) are associated in the litigation data.

The IPR is the single richest source of actually-litigated prior art for this patent — the petition and Final Written Decision will contain the precise references and the claim charts you want. I did not retrieve those documents within my search budget, so I cannot name the specific references with confidence.

5. § 102 framework for the claim set (how to finish the analysis)

Because the exact front-page citations weren't retrievable, here is how to evaluate each reference once you pull them (all of this is generic to the claim language, not invented citations):

• Claim 1 turns on three structural elements: (a) a client device running a browser/email app; (b) establishment of a TCP connection to a "second server"; (c) sending content received from the web server to that second server over the TCP connection. To anticipate under § 102, a reference must disclose all of these in a single teaching — most proxy/relay/caching art (e.g., transparent proxy patents, split-connection proxies) is the natural place to look.
• Chunking / checksum-keyed chunks / peer lists / agent assignment (described throughout the spec) map to the dependent claims (e.g., 2, 6–11, 13, 15, 16) — CDN, P2P, and distributed-cache art are the relevant § 102/§ 103 references there.
• Validity-checking of cached HTTP content (FIG. 12) is the subject of the conditional-request limitation in some dependent claims.

6. Recommendation

To produce the reference-by-reference table you asked for, retrieve the primary source directly:

1. Justia — https://patents.justia.com/patent/11044342 → "References Cited" / "Patent History" section.
2. Google Patents — https://patents.google.com/patent/US11044342/en → "Citations" / "Similar Documents" tabs (patent and non-patent).
3. PTAB — IPR2022-00103 petition and Final Written Decision (petitioner Code200, UAB / Unified Patents).

I cannot responsibly supply the specific cited patent numbers or map them to claims without seeing that list — my searches within budget did not surface it, and the results that superficially resembled it belonged to other patent numbers that I must not conflate with US 11,044,342.

I'll ground this analysis in the actual record. First, let me check what prior art is actually associated with this patent and the PTAB proceeding.

Let me pull the claim language and the specific prior-art grounds from the PTAB record.

Scope note and a required caveat

You asked me to "use the results from the Prior Art section of this page." I need to be precise about what that section actually contains, because it affects the reliability of the analysis:

The "Prior Art" information on the supplied US11044342 Google Patents page consists only of:

• Prior art keywords: server, client, client device, internet, request
• Prior art date: 2009-10-08

The page as fetched does not enumerate any cited prior-art references (no "References Cited" list is present in the retrieved text; the Espacenet citation view for this patent likewise shows "0 documents cited in US11044342 (B2)"). So I cannot build a § 103 analysis from a reference list that the page doesn't contain, and I will not invent one.

What I can do — and what I do below — is ground the analysis in the prior art that is of record against this exact claim set: the references adjudicated in IPR2022-00103, whose Final Written Decision issued May 30, 2023, and which was affirmed by the Federal Circuit on August 1, 2025 (Bright Data, Ltd. v. Code200, UAB, Nos. 2023‑2144 et al.). That is the authoritative, on-point art for US11044342, and it is materially better evidence than anything derivable from the keyword list.

Second caveat: the supplied page text does not include the actual claim set (the claims section is absent from the fetched content). The claim-1 recitation below is assembled from the Espacenet claim listing for US11044342B2 and from the PTAB/Federal Circuit record. I flag exact-claim-language uncertainty where it matters.

1. The patent and the claim at issue

Two claim constructions were dispositive in the parallel litigation/IPR and frame the whole § 103 analysis:

• "client device" = "a communication device that is operating in the role of a client"
• "second server" = "a device that is operating in the role of a server" and is not the client device

The Board and the Federal Circuit both rejected Bright Data's narrower, hardware-based constructions ("computer of a consumer" / commercial server), reasoning from the specification's own statement that each device runs "a client module 224, a peer module 226, and an agent module 228, each of which comes into play according to the specific role that the communication device 200 is partaking in the communication network 100 at a given time" ('342 pat. col. 9:20–25). This is the single most important fact for obviousness: under role-based construction, a peer-to-peer node that relays a request and returns content can simultaneously satisfy "client device" and "second server."

Claim 1 (as rendered by Espacenet for US11044342B2) reads, in substance:

A method for use with a web server that responds to HTTP requests and stores a first content identified by a first URL, the method by a first client device comprising: executing a web browser application or an email application; establishing a TCP connection with a second server; receiving the first content from the web server over an Internet; and sending the received first content, to the second server over the established TCP connection, in response to the receiving of the first URL.

In the sibling '319/'510 family, the corresponding independent claim is the "relay" formulation: receiving the first URL from the second server → sending an HTTP request comprising the first URL to the web server over the Internet → receiving the first content from the web server → sending the first content to the second server.

Either way, the claim is a generic relay/tunnel method: (i) a first device running a browser/mail client; (ii) a TCP connection to a second device; (iii) fetching content from a web server; (iv) forwarding that content back over the TCP connection.

2. The prior art of record against these claims

From the IPR2022-00103 record (as reproduced in the Supreme Court petition appendix, Bright Data Ltd. v. Code200, UAB, No. 25‑779):

All of Crowds, Border, MorphMix and RFC 2616 comfortably predate the 2009-10-08 priority date.

3. Element-by-element § 103 mapping

Ground A — Crowds (primary), alone or + RFC 2616

Crowds describes a "crowd" of users whose computers ("jondos") collectively issue HTTP requests on behalf of a member to protect anonymity. On the record:

• "executing … a web browser application" — Crowds § on user requests originating from a browser on the initiator jondo (Ex. 1006 at 73).
• "establishing a TCP connection with a second server" — Crowds establishes a "static path" of jondos "over TCP," disclosed via statements about the path being "altered when failures are detected," including "the TCP/IP connection to the jondo breaking or being refused" (Ex. 1006 at 81).
• "second server" — Crowds expressly uses "client-server terminology, where one jondo is a client of its successor on the path" (Ex. 1006 at 74); the successor (e.g., jondo 4) therefore operates "in the role of a server" to the requesting jondo.
• "receiving the first content from the web server over an Internet" — the final jondo forwards the request to web server 5 and receives the response.
• "sending the received first content to the second server over the established TCP connection" — the response is propagated back along the static path.
• RFC 2616 supplies the HTTP request form and the URL-as-content-identifier requirement (§ 5.1.2).

Ground B — Border (primary), alone or + RFC 2616

Border (US 6,795,848 B1) is a proxy architecture with a downstream proxy server and an upstream proxy server:

• first client device = "upstream server 107"; second server = "downstream server 105"; first server / web server = "web server 109."
• downstream server 105 receives a URL request from browser 103 and forwards it to upstream server 107 ("receiving, from the second server, the first content identifier");
• upstream server 107 issues a GET to web server 109 ("sending, to the first server over the Internet, an HTTP request that comprises the first content identifier");
• web server 109 returns the requested HTML page to upstream server 107 ("receiving the first content from the first server over the Internet");
• upstream server 107 "forwards the HTML page to the downstream server 105," which returns it to browser 103 ("sending the first content … to the second server").
• Border further discloses an HTTP cache 117 at upstream server 107 (relevant to dependent "storing" claims).

Border's Figure 2 is a sequence diagram of exactly this relay.

Ground C — MorphMix (primary) + RFC 2616

MorphMix is a peer-to-peer mix network in which every node is simultaneously a client and a mix/relay:

• node a establishes a TCP connection to node b by connecting to ip_b:p_mmb (Ex. 1008, § 5.2) → the "established TCP connection with a second server";
• the final node in the tunnel establishes a TCP connection to the contacted web server and retrieves the content;
• content flows back through the tunnel to the initiator → "sending the received first content … over the established TCP connection";
• the system explicitly runs over HTTP/TCP/IP and supports browser-driven URL requests.

Ground D — combinations expressly adjudicated

The Final Written Decision in IPR2022-00103 found claims 1, 2, 6–11, 13, 15, 16, and 18–23 of the '342 patent unpatentable over Crowds, Border, MorphMix, and/or Plamondon. The Federal Circuit affirmed that the Board "found that Crowds both anticipated and rendered obvious the claims at issue on appeal."

4. Why a POSITA would have combined these references (the motivation inquiry)

Under KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007), and Graham v. John Deere Co., 383 U.S. 1 (1966), the record supports multiple independent, articulated rationales:

1. Same field of endeavor. Crowds, MorphMix, and Border all address relaying HTTP requests through intermediary nodes over TCP/IP to reduce/obscure direct client-server traffic. All are in the field of network content distribution and web-request routing — the field of the '342 patent.

2. Known techniques used for their established functions (KSR, "familiar elements"). Proxy caching (Border), P2P/mix relay (Crowds, MorphMix), and HTTP over TCP (RFC 2616) each retain their known function in the combination. Nothing in the combination changes the principle of operation of any element; the combination is a predictable arrangement of known relay components.

3. Explicit motivation in the cited references themselves. MorphMix's own comparison section discusses and contrasts itself with Crowds, analyzing Crowds' centralized lookup service, scaling behavior, and last-hop page retrieval (Ex. 1008 § 9.3.1). A POSITA reading MorphMix is thereby expressly directed to Crowds and to the tradeoffs between a centralized lookup/agent server (Crowds) and a decentralized peer-discovery approach (MorphMix). That is a textbook teaching-away/suggestion analysis arising within the art itself.

4. Common, standards-defined environment. Both Crowds and MorphMix operate over standard TCP/IP and HTTP. As the Board accepted in the parallel '319 IPR (IPR2022-00861, Paper 19), because MorphMix "is also directed at improving communications … using standard protocols such as TCP/IP," a POSITA "would have had a powerful motivation … to combine its disclosure with other knowledge of Internet standards and/or RFC 2616 governing HTTP."

5. Market/design demand acknowledged by the patent itself. The '342 specification states the need for "a new method of data transfer that is fast for the consumer, cheap for the content distributor and does not require infrastructure investment for ISPs" (1:54–56) and criticizes conventional proxies and P2P file-sharing as unable to handle dynamic HTTP data. Border's caching proxies and Crowds/MorphMix's peer relay networks are directly responsive to the same latency/bandwidth/cost problems — providing the "demand known in the marketplace" rationale of KSR.

6. Reasonable expectation of success. Each reference is a complete, working system for relaying an HTTP request and returning content. The combination requires no unpredictable engineering: the relay steps are the references' actual disclosed operations.

7. Role-based construction unlocks the combination. Because "client device" and "second server" are role-based, Border's upstream proxy server 107 can be the "first client device" while still "operating in the role of a client" toward web server 109; likewise, Crowds' and MorphMix's nodes can occupy both roles at different times. Bright Data's contrary argument — that a device must be locked to a single role — was rejected by the Board and the Federal Circuit.

Bright Data's counter-arguments and why they failed: Bright Data argued (i) hardware-based constructions, (ii) that MorphMix "teaches away" from using servers because it is peer-to-peer ("there is no distinction between clients and mixes … every participating node is both a client and a mix at the same time," Ex. 1008 at 168), and (iii) MorphMix's latency deficits. The Board and Federal Circuit rejected these because the claims are role-based, not architecture-based, and because a POSITA need not abandon P2P to read a role-based claim onto a peer node acting as a server to its predecessor.

5. Dependent claims (2, 6–11, 13, 15, 16, 18–23)

These were all the subject of IPR2022-00103 and were found unpatentable, in each case by mapping the added limitations onto the same primary references and general knowledge:

• Client-device-as-intermediary / storing the fetched content (e.g., claim 17 in the sibling '319 claim set, recited as "storing, by the first client device … the first content") → Border's HTTP cache 117 ("upstream server 107 stores the first content in HTTP cache").
• Validity/refresh of cached data → RFC 2616 cache-control semantics (max-age, no-cache) and conditional requests, as the '342 specification itself acknowledges at FIG. 12 ("HTTP … defined by RFC 2616").
• Periodic communication / maintaining a path or tunnel between devices → MorphMix's virtual links/tunnels (Ex. 1008 § 5.2; Board credited this for the '319 claim 17).
• Node/peer discovery → Crowds' centralized lookup server and MorphMix's node-lookup list (§§ 5.7–5.8).

6. Secondary considerations (§ 103 objective indicia)

Bright Data submitted evidence of commercial success of its residential-proxy service. The Board found the evidence "lacked probative value because Bright Data failed to demonstrate the requisite nexus between its evidence and its claims," and the Federal Circuit affirmed on the nexus question and on the claim constructions. Where a patent's claims are broad, role-based relay methods and the asserted commercial product embodies substantial unclaimed functionality, the presumption of nexus does not attach — killing this WBIP-type defense.

7. Adjudicated outcome (as of today, April 26, 2026)

• IPR2022-00103, Final Written Decision May 30, 2023: claims 1, 2, 6–11, 13, 15, 16, 18–23 of US 11,044,342 B2 unpatentable.
• Fed. Cir. Nos. 23‑2144 et al., decision August 1, 2025: affirmed (consolidated appeals covering the '342, '319, '510, and '344 patents). Role-based constructions affirmed; Crowds anticipation and obviousness affirmed; nexus finding affirmed.
• Supreme Court No. 25‑779: petition denied (news reporting dated March 2, 2026 — "Justices Won't Eye Axed Bright Data Patents From $7.5M Case"). The '342 patent's asserted claims are therefore effectively terminated.

8. Bottom line

Under § 103, US11044342's claims would have been obvious over (1) Crowds + RFC 2616, (2) Border + RFC 2616, (3) MorphMix + RFC 2616, and combinations thereof — and that is exactly what the PTAB held and the Federal Circuit affirmed. The motivation is supplied by the shared field (HTTP relay through intermediary nodes), the references' mutual cross-referencing (MorphMix expressly compares itself to Crowds), the standards-defined TCP/IP+HTTP environment, the market demand the patent itself recites, and the predictable nature of combining known relay, caching, and P2P elements — with no change in their respective functions.

Confidence and limitations:

• High confidence in the reference set, the grounds, the constructions, and the outcome (multiple independent primary sources agree).
• Medium confidence in the precise wording of claim 1 as quoted above — the supplied page omits the claim set, so I relied on Espacenet's listing plus the PTAB record, and the Espacenet rendering appears abridged.
• Low confidence on the identity and content of "Plamondon" — I could not verify it within the available tool budget and have not attributed any specific disclosure to it.

If you want, I can attempt a dedicated lookup to pin down "Plamondon" and to reproduce the full dependent-claim set of the '342 patent so the chart can be completed at claim-level granularity.
