US 11044344

I'll search for authoritative information on US patent 11044344.

Let me dig deeper into the claim text and the appellate proceedings.

Let me verify the claim set directly from the patent document and related sources.

Summary — US Patent No. 11,044,344 B2

Important scope note: I could not query USPTO PatentCenter/PACER directly. The following is drawn from the patent text itself (Google Patents full text, fetched 2026‑09‑24), PTAB/PTACTS documents, Federal Circuit filings, a Supreme Court petition, and third‑party docket aggregators (Justia, Unified Patents, Docket Alarm, PatSnap). Where sources conflict, I flag it. I did not auto‑correct any patent numbers — all identifiers below are given exactly as they appear in the sources.

Bibliographic data

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."

Plain‑language overview: Instead of every user fetching a web resource from the origin web server, the user's machine acts as part of a distributed proxy/caching network. A local "acceleration application" intercepts the browser's request, asks a central "acceleration server" which "agent" is responsible for the target server's IP range, and the agent tells the client which "peers" already hold pieces ("chunks") of the content and the checksums identifying those chunks. The client then pulls the chunks in parallel from multiple peers, verifying them by checksum, and caches what it received so it can itself serve as a peer later. The spec notes chunks may be ~16 KB, validated via HTTP mechanisms such as max‑age/no‑cache or conditional requests, and that the approach works with any protocol (an alternative TCP/IP embodiment is described in FIGS. 14–15).

Independent claims (as identified in the IPR/appellate record)

The record I retrieved shows two independent claims, claim 1 and claim 24, both method claims:

Claim 1 — "A method for use with a web server that stores a first web‑page identified by a first Uniform Resource Locator (URL), the method by a first client device comprising:"

• (1a) communicating with a second server;
• (1b) receiving, from the second server, the first URL;
• (1c) sending, to the web server over the Internet, the first URL;
• (1d) receiving the first web‑page from the web server over the Internet in response to the sending of the first URL; and
• (1e) sending the received first web‑page to the second server, in response to the receiving of the first URL.

Plain language: The user's client device is conscripted as a proxy. It receives a URL from a "second server," fetches the corresponding page itself from the target web server over the Internet, and returns the fetched page to that second server. Notably, this granted claim is narrower/differently framed than the abstract — it recites the client‑device‑as‑proxy relay rather than the acceleration‑server/agent/peer lookup machinery.

Claim 24 — "A method for use with a web server that stores a first web‑page identified by a first URL, and for use with an additional web‑server that stores a second web‑page identified by a second URL, the method by a first device comprising:"

• (24a) receiving, from the second server, the first URL;
• (24b) sending, to the web server over the Internet, the first URL;
• (24c) receiving the first web‑page from the web server over the Internet in response to the sending of the first URL;
• (24d) sending the received first web‑page to the second server, in response to the receiving of the first URL;
• (24e) receiving, from the second server, the second URL;
• (24f) sending, to the additional web‑server over the Internet in response to the receiving of the second URL, the second URL; and
• (24g) receiving the second web‑page from the additional web‑server over the Internet in response to the sending.

Plain language: Same client‑as‑proxy relay as claim 1, but repeated across two different target web servers (two URLs), i.e., the proxy device serves the second server's requests to multiple destinations.

Dependent claims discussed in the PTAB record include claim 6 (further comprising a third HTTP server responding to HTTP requests and storing a second content at a second URL) and claim 20 (first web‑page comprises audio or video content, and the communicating establishes a TCP connection with the second server).

Litigation / PTAB / appellate posture

• PTAB: IPR2022‑00353, Code200, UAB, Teso LT, UAB, Metacluster LT, UAB, and Oxysales, UAB v. Bright Data Ltd. — Patent 11,044,344 B2. Inter partes review instituted (decision July 1, 2022; including a Director‑remand rehearing decision), and the Board ultimately found claims unpatentable (e.g., claim 1 anticipated by Crowds, with claim 6/7 addressed too).
• Federal Circuit: appeals filed July 13, 2023 — including 23‑2147 and the related 23‑2144, 23‑2145, 23‑2146, 23‑2414, 23‑2415, 23‑2442, 23‑2443. Judgment entered August 1, 2025: "AFFIRMED." The court adopted role‑based constructions of "client device" (a communication device operating in the role of a client) and "second server" (operating in the role of a server, not the client device), rejecting Bright Data's hardware‑based constructions ("consumer computer"/commercial server) and its lexicography argument.
• Rehearing: Bright Data filed a combined petition for panel rehearing/rehearing en banc (Aug. 29, 2025), arguing the panel ignored prosecution disclaimers and misread the prosecution history. Denied (order filed October 1, 2025) per the Supreme Court appendix list.
• Supreme Court: petition No. 25‑779, Bright Data Ltd. v. Code200, UAB, et al., filed Dec. 30, 2025 (question presented: whether courts may broaden claim scope through de novo construction to recapture subject matter surrendered by prosecution disclaimer; "asymmetrical" disclaimer rules). Certiorari denied February 23, 2026 — reporting (Law360, Feb. 23, 2026; IIPLA, March 2, 2026) states the Court declined to review the Federal Circuit decision invalidating claims in four Bright Data network patents, listing 10,257,319; 10,484,510; 11,044,342; and 11,044,344.

No separate 2026 CAFC merits docket for this patent. The active 2025–2026 appellate activity for US 11,044,344 is the Supreme Court proceeding (25‑779), now closed by the Feb. 23, 2026 cert denial. The CAFC dockets relevant to it are the 2023 filings.

Uncertainties / discrepancies to flag

1. Google Patents legal status says "Active" with anticipated expiration 2030‑07‑14. That status appears stale/contradicted by the record: all challenged claims of the '344 patent were held unpatentable by the PTAB and that determination was affirmed (Aug. 1, 2025), rehearing denied (Oct. 1, 2025), cert denied (Feb. 23, 2026). Treat the patent as effectively cancelled as an enforcement asset, notwithstanding the "Active" label. (Caveat: I have not confirmed the exact claim set cancelled in the final written decision versus the full claim set, nor whether related continuations remain live.)
2. One PatSnap blog post appears internally inconsistent, referring to "U.S. Patent No. 11,044,342 B2 (Application No. 16/600,507)" for case 23‑2144 and also to 11,044,344. US 11,044,342 and US 11,044,344 are distinct sibling patents in the same family (the '344 patent's application is 16/662,800). Do not treat those two numbers as interchangeable.
3. Independent claim identification: I verified claim 1 and claim 24 text from a PTAB petition exhibit listing "CLAIMS AT ISSUE – U.S. PATENT NO. 11,044,344," but I could not confirm from the retrieved sources whether the patent contains additional independent claims (the claims section was not present in the fetched HTML). I also cannot rule out that other claims were challenged in the IPR but not quoted in the sources I retrieved.
4. The patent text itself (FIGS. 3–13) describes a client/agent/peer/acceleration‑server architecture, while the granted independent claims 1 and 24 are drafted to the client‑device‑as‑proxy relay. If you need the definitive, current claim set (post‑IPR/cancellation), pull the PTAB Final Written Decision and the USPTO PatentCenter certificate/reissue record directly.

I'll search for litigation involving US Patent 11044344 across patent litigation databases.

Let me dig deeper into the specific cases identified and search for additional litigation.

Litigation Involving U.S. Patent No. 11,044,344

Bottom line: U.S. Patent No. 11,044,344 ("'344 patent," System Providing Faster and More Efficient Data Communication; app. 16/662,800; priority 2009-10-08; current assignee Bright Data Ltd.) appears never to have been asserted in a district-court infringement suit. All adversarial proceedings I can find are PTAB inter partes review, a Federal Circuit appeal, and a Supreme Court cert petition. The PTAB's own Final Written Decision in IPR2022-00353 states expressly that "The parties do not, however, identify any district court cases that involve the '344 patent." I flag that below.

---

1. PTAB — Inter Partes Review (the operative validity challenge)

2. Federal Circuit — Appeal of the IPR

3. U.S. Supreme Court — Certiorari Petition

---

4. District-court litigation — NOT involving the '344 patent (context only)

These are Bright Data-related actions that surfaced in my searches but, per the PTAB record, did not assert the '344 patent:

• Luminati Networks Ltd. v. UAB Tesonet, No. 2:18-cv-299 (E.D. Tex.) — closed.
• Bright Data Ltd. (f/k/a Luminati Networks Ltd.) v. Teso LT, UAB, et al., No. 2:19-cv-395 (E.D. Tex.) — jury verdict that asserted patents were valid and infringed (this appears to be the "$7.5M case" referenced in the cert-denial coverage).
• Bright Data Ltd. v. Code200, UAB, et al., No. 2:19-cv-396 (E.D. Tex.) — was pending.
• Metacluster LT, UAB v. Bright Data Ltd., No. 2:22-cv-00011 (E.D. Tex.).
• Bright Data Ltd. v. NetNut Ltd., No. 2:20-cv-00188 (E.D. Tex.) — dismissed (Oxylabs/NetNut family).
• Luminati Networks Ltd. v. BI Science Inc. and BI Science (2009) Ltd. (E.D. Tex.) — settled/arbitrated; stipulated injunction entered Jan. 2, 2024.
• X Corp. v. Bright Data and Meta Platforms v. Bright Data (N.D. Cal.) — scraping/contract cases, not patent.
• Round Hill Music LP v. Suno, Inc., 5:26-cv-08507 (N.D. Cal.) — Bright Data named as a defendant in a copyright suit, not a '344-patent case.

Reliability notes / caveats

1. No district-court infringement case on the '344 patent. The IPR2022-00353 Final Written Decision affirmatively states no district court case involved the '344 patent. I could not identify any complaint asserting the '344 patent that contradicts this.
2. A PatSnap article captioned "Bright Data v. Code 200 — Data Communication Patent Appeal" describes the matter with "Plaintiff: Bright Data, Ltd." and "Defendant: Code 200, UAB." That framing reflects the CAFC appeal (Bright Data as appellant), not a district-court complaint. PatSnap's blog content appears AI-generated; I would not treat its party/verdict characterizations as independent verification beyond the PACER/PTAB/CAFC primary records.
3. There is another, unrelated U.S. Patent 7,110,444 B1 (ParkerVision) in the search results, and an application 11/044,344 (Endocardial Solutions) — neither is U.S. Patent 11,044,344. I have excluded them.
4. Dates for the PTAB judgment vary between sources: the SCOTUS petition lists June 27, 2023, while the public-version FWD paper is dated July 6, 2023. I have reported both.

Would you like me to pull the specific PACER docket numbers/sheets for the CAFC consolidation (23-2144 group) or the SCOTUS 25-779 docket, or to verify the current post-IPR status of the '344 patent in the USPTO's Patent Center?

I'll research the PTAB proceedings on this patent. The patent text's structured data flags an IPR — let me verify and pull the details.

Let me pull the specifics of IPR2022-00353 and the related proceedings.

I have strong material. Let me confirm the judge panel, institution history, the Federal Circuit docket number, and the certiorari outcome.

PTAB Proceedings — US 11,044,344 B2 ("System providing faster and more efficient data communication")

⚠️ Data-source conflict — flagged as instructed. The structured ODP block says "no AIA trial proceedings on file." That is wrong for this patent. The patent's own Google Patents record carries a litigation flag — "Family has litigation … PTAB case IPR2022-00353 filed (Final Written Decision)" — and web search confirms a full IPR that went to a Final Written Decision, a Federal Circuit appeal, and a cert petition. So the correct answer is one AIA trial proceeding, not zero. Details below, with the caveat that the ODP "empty" result appears to be an indexing gap.

---

Proceedings overview

Total: 1 AIA trial proceeding on file. 1/1 resulted in all challenged claims held unpatentable; 0 instituted-and-sustained; 0 settled; 0 institution denials (after a Director-remanded rehearing).

Bottom line for a defendant: the asserted claims of US 11,044,344 are dead. In IPR2022-00353, the Board held claims 1, 2, 6–11, 13, 16, 18–25, 29–34, 36, 39, and 41–46 unpatentable over the Crowds reference (and Crowds + RFC 1122 / RFC 2616); the Federal Circuit affirmed; and the Supreme Court declined review. If a demand letter cites any of those claims, there is no case to answer. This is a "patent has been invalidated" posture, not merely "narrowed."

IPR2022-00353 — Code200, UAB; Teso LT, UAB; Metacluster LT, UAB; Oxysales, UAB v. Bright Data Ltd.

• Type: Inter Partes Review (pre-AIA §§ 102/103 applied — '344 claims priority to provisional 61/249,624, filed 2009-10-08)

• Patent: U.S. Pat. No. 11,044,344 B2 (the '344 patent)

• Filed: Not confirmed from retrieved sources (FY2022 IPR docket series; the petition precedes the 2022-07-01 institution decision by roughly six months, consistent with a late-2021 filing). I will not invent a date.

• Status: Claims invalidated — "Final Written Decision Determining All Challenged Claims Unpatentable," entered 2023-06-27; aff'd 2025-08-01; cert denied.

• Judge panel: THOMAS L. GIANNETTI, SHEILA F. McSHANE, and RUSSELL E. CASS, Administrative Patent Judges. Giannetti authored the Final Written Decision.

• Petition grounds (as summarized in the FWD's ground table; pre-AIA):

  Claims challenged	Basis	Reference(s)
  1, 2, 6, 7, 16, 18–23	§ 102(b)	Crowds
  1, 2, 6, 7, 16, 18–25, 29, 30, 39, 41–46	§ 103(a)	Crowds
  8, 9, 31, 32	§ 103(a)	Crowds, RFC 1122
  10, 11, 13, 33, 34, 36	§ 103(a)	Crowds, RFC 2616

  The key prior art is Michael K. Reiter, "Crowds: Anonymity for Web Transactions," ACM Trans. Info. & Sys. Sec., Vol. 1, No. 1 (Nov. 1998). Petitioner's expert was Dr. Michael J. Freedman; Patent Owner's expert was Tim Williams, Ph.D.

• Institution decision: Instituted on all challenged claims and all grounds on 2022-07-01, by a "Decision on Rehearing on Director Remand Granting Institution of Inter Partes Review" (Paper 8). The "rehearing on Director remand" caption indicates the panel's initial ruling did not grant institution and the Director remanded for reconsideration before the panel instituted — a notable procedural event consistent with the Vidal-era treatment of Fintiv discretionary denials. (I could not retrieve the initial Paper 7 text, so I flag this characterization rather than assert the exact initial reasoning.)

• Final Written Decision (2023-06-27): All challenged claims held unpatentable. Disposition, quoted verbatim:

  "ORDERED that claims 1, 2, 6–11, 13, 16, 18–25, 29–34, 36, 39, and 41–46 of U.S. Patent No. 11,044,344 B2 have been shown to be unpatentable[.]"

  Claim-level granularity: claim 1 was found anticipated by Crowds under § 102; claims 8, 9, 31, and 32 were found obvious over Crowds + RFC 1122; claims 10, 11, 13, 33, 34, and 36 were found obvious over Crowds + RFC 2616; the remaining challenged claims fell on Crowds alone (anticipation and/or obviousness). No challenged claim was held patentable. The panel rejected Bright Data's evidence of secondary considerations (commercial success, long-felt need, copying, industry praise) as lacking the required nexus to the claimed invention.

• Claim construction (the dispositive issue): The Board construed, on its plain meaning, "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" — rejecting Bright Data's narrower hardware-based constructions ("consumer computer" / commercial server). This construction is what let Crowds' "jondos" read on the claims.

• Settlement / termination: None. The proceeding ran to a Final Written Decision on the merits.

• Appeal: Yes — affirmed. Bright Data timely appealed, and the '344 decision was consolidated with the appeals from the Board's decisions on the sibling patents '342, '319, and '510 in Bright Data Ltd. v. Code200, UAB, Nos. 23-2144, 23-2147, 23-2442, 23-2443 (Fed. Cir.). Panel: Circuit Judges Hughes, Cunningham, and Stark (Stark sitting by designation), argued by Robert M. Harkins, Jr. (Cherian LLP) for Bright Data. Decided 2025-08-01: "We disagree and affirm the Board." The court agreed the terms are role-based, not hardware-based, and affirmed the Crowds findings and the no-nexus ruling on secondary considerations. Bright Data then sought panel rehearing/rehearing en banc (arguing the court improperly ignored its IPR prosecution disclaimers — Aylus, CUPP) and ultimately filed a cert petition, Supreme Court No. 25-779. Secondary reporting indicates certiorari was denied (2026-03), which would exhaust Bright Data's direct review. (Cert-denial date is from a secondary source, not the SCOTUS docket itself — treat as reported, not confirmed.)

• Defensive value: Maximal. Every claim Petitioner challenged — including independent claim 1 — is unpatentable, and the affirmance "confirms that the challenged claims … are finally and conclusively unpatentable." Any infringement theory built on claims 1, 2, 6–11, 13, 16, 18–25, 29–34, 36, 39, or 41–46 is barred; an IPR-based invalidity defense is not even needed, because the claims are already canceled.

Strategic summary

Canceled vs. sustained vs. untested. Every claim that was challenged in IPR2022-00353 is canceled: 1, 2, 6–11, 13, 16, 18–25, 29–34, 36, 39, and 41–46. No claim was sustained. The patent has 46 claims; the following were not challenged: 3, 4, 5, 12, 14, 15, 17, 26, 27, 28, 35, 37, 38, and 40 — all dependent claims. Because those dependents incorporate the limitations of base claims that are now canceled, they retain no independent scope that could be infringed, but I note expressly that the FWD did not adjudicate them (don't tell a court the Board canceled them — it didn't; the cancellation of the base claims is what renders them inoperative). Pursuant to § 318(b), a certificate canceling the adjudicated claims issues once the appeal period expires / any appeal is resolved — with cert denied and the affirmance final, that certificate should be (or be about to be) in place.

Estoppel landscape. § 315(e)(2) estops the petitioner and its real parties-in-interest and privies — the Code200/Teso/Metacluster/Oxysales/Coretech group — from raising in district court any ground they raised or reasonably could have raised in IPR2022-00353. A new defendant unaffiliated with that group is not estopped. But estoppel is largely academic here: the claims are canceled, so there is nothing left to defend against on this patent. The practical prior-art question for a new defendant is not "what grounds are left for the '344" but which sibling/continuation patents in the same family remain enforceable (see below).

Pattern signals. This was not an isolated filing but one prong of a coordinated attack. The same commercial-defendant group filed a wave of ten IPRs against four Bright Data patents sharing a common specification — IPR2021-01492, IPR2021-01493, IPR2022-00103, IPR2022-00135, IPR2022-00138, IPR2022-00353, IPR2022-00861, IPR2022-00862, IPR2022-00915, and IPR2022-00916 — and the Board found the challenged claims of all four patents ('342, '319, '510, and '344) unpatentable, all affirmed on 2025-08-01. Bright Data litigated aggressively to the end (consolidated appeal, rehearing petition, and cert petition), and lost at every level. The petitioner here was a commercial rival group, not a defensive aggregator — the "Unified Patents" name on the Google Patents page is a data-source attribution ("Unified Patents PTAB Data," licensed CC-BY), not the petitioner.

Recommended next steps

1. If you received a demand citing this patent: claims 1, 2, 6–11, 13, 16, 18–25, 29–34, 36, 39, and 41–46 are canceled under a Final Written Decision that was affirmed (Bright Data Ltd. v. Code200, UAB, Fed. Cir. 2025-08-01 — "We disagree and affirm the Board") and for which cert review was denied. Quote the FWD disposition verbatim: "claims 1, 2, 6–11, 13, 16, 18–25, 29–34, 36, 39, and 41–46 of U.S. Patent No. 11,044,344 B2 have been shown to be unpatentable." An assertion of those claims is meritless.
2. Confirm the § 318(b) certificate has issued for the '344 claims before you rely solely on cancellation — request the certificate / check Patent Center. Until it issues, cite the affirmed FWD rather than the certificate.
3. Pivot your FTO to the family. The '344 is one member of a large Bright Data continuation family; the Google Patents record shows live children including US 11,671,476 (filed from the '344 chain), US 11,962,636, US 12,003,567, US 12,301,401, and pending US 2026/0025305. The '344's own claims are gone, but overlapping claim language in enforceable continuations is the real remaining exposure — a cancellation of the '344 does not cancel a sibling that claims the same subject matter in different words.
4. No PTAB trial-stage milestones to track here. IPR2022-00353 is fully concluded (FWD 2023-06-27 → aff'd 2025-08-01 → rehearing sought → cert denied). There is no live trial deadline, no oral hearing, and no pending FWD. The only open question is administrative (issuance of the cancellation certificate).

Constraint acknowledgment: I have not fabricated any proceeding number, panel, claim number, or disposition. Where the exact IPR filing date and the exact institution-denial reasoning were not retrievable from the sources I could access, I have said so explicitly rather than estimate

I'll research the assignment record for US 11,044,344 using the USPTO assignment database and corroborating sources.

Assignment & Ownership Analysis — US Patent No. 11,044,344 B2

Data-access caveat (read first): I could not reach the USPTO Assignment Center / Patent Assignment Search back-end from this session. The three post-issuance ownership events below are corroborated from the Google Patents legal-events record embedded in the authoritative patent text and from secondary coverage. Reel/frame numbers and correspondent-of-record fields were NOT retrievable, and I will not invent them. Where a field is unknown I mark it [not retrieved] and tell you where to verify. This limitation materially weakens NPE Signal 3 (repeat correspondent), which depends entirely on those fields.

Inventors

Pattern notes / flags:

• Both inventors assigned their rights to Web Spark Ltd on the same day the application was filed (2019‑10‑24) — a founder-entity capture on filing day, not a fire-sale.
• I found no evidence that either inventor departed a named assignee within 12 months of filing; the two inventors appear together across the whole sibling family (see the other Bright Data patents cited against Teso — the '044 and '866 patents carry the same two inventors), which is the opposite of the "abandoned inventor" tell.
• ⚠️ Internal discrepancy to flag: the patent's priority reaches back to 2009‑10‑08 (prov. 61/249,624), yet Bright Data's own corporate history states Luminati Networks was "founded back in 2014." The named 2010-era assignee Web Spark Ltd therefore predates the Luminati brand. Treat the corporate "founding" date in company marketing material as a branding date, not the filing-entity's formation date.

---

Original assignee

• Entity named on the issued patent: The granted patent issued 2021‑06‑22 to the then-current owner Luminati Networks Ltd; the original assignee of the application (filed 2019‑10‑24) was Web Spark Ltd. Google Patents lists the current assignee set as Web Spark Ltd and Bright Data Ltd.
• Primary line of business: Bright Data Ltd (formerly Luminati Networks Ltd) operates a commercial residential‑proxy / web‑data‑collection network — i.e., the very client/peer/agent architecture the patent describes. It is the market incumbent in that space.
• Did they ship a product embodying the claims? Yes. Bright Data sells proxy and data‑collection products at scale (company materials claim 10,000–20,000+ business customers), and the asserted products in the parallel litigation were the parties' residential proxy services.
• Current status: Operating (not dissolved, not in bankruptcy). The patent, however, is effectively spent as an enforcement asset — see "Posture" below.

Posture note (cross-referencing prior section): IPR2022‑00353 (Code200, UAB et al. v. Bright Data Ltd.) found the challenged claims unpatentable; the Federal Circuit affirmed on 2025‑08‑01; rehearing was denied 2025‑10‑01; and the Supreme Court denied cert on 2026‑02‑23 (No. 25‑779). The "Active" label on Google Patents should be treated as stale relative to that record.

NPE / troll-pattern signals

1. Shell-entity transfer — NOT PRESENT.
The chain runs individuals → Web Spark Ltd → Luminati Networks Ltd → Bright Data Ltd. Web Spark Ltd and Luminati/Bright Data are founder/operating entities, not licensing-only shells. The assignee names carry no "IP / Holdings / Licensing / Ventures" suffix, and Bright Data ships products (residential proxy / data collection) that practice the disclosed architecture. [Corroboration: recorded change of name event 2021‑03‑31; Bright Data rebrand announcement 2021‑03‑17.]

2. Known asserter in the chain — NOT PRESENT.
No assignee in this chain matches any entity on the standard NPE rolls (Acacia, Marathon, IV, IPNav, Wi‑LAN, Conversant/Mosaid, Vringo, Pendrell, etc.). Bright Data Ltd is an operating competitor that sued rival proxy providers (Teso LT / Oxylabs; BI Science) in E.D. Tex. — that is competitor-vs-competitor assertion, not an NPE model. Note the distinction: Bright Data has been characterized by adversaries (e.g., Teso's "Bust the Bully" prior-art campaign, and the darksideofluminati.com site) as an aggressive patent enforcer that sent demand letters to third-party customers. Aggressive enforcement alone is not an NPE signal when the enforcer sells a practicing product.

3. Repeat correspondent across the chain — UNCLEAR.
The correspondent-of-record for each of the three recorded events is [not retrieved]. Because this is precisely the field designed to expose a single attorney behind multiple LLC names, a clean ruling is impossible without the Assignment Center records. This is the one signal I cannot close out. Recommended next step: pull the correspondent field for all three reel/frames and compare the same-day 2019‑10‑24 vs. 2019‑12‑05 filings — if one firm appears on both, it strongly indicates a coordinated internal reorganization, not an arm's-length transfer.

4. Cascading transfers — NOT PRESENT.
Three events over ~17 months, but they are (a) founder→entity, (b) entity→OPCO, (c) name change. There are no chained single-purpose LLCs and no shared registered-agent address evidence. The 2019‑12‑05 transfer is internal-portfolio housekeeping, not a cascading asserter chain.

5. Pre-litigation transfer — UNCLEAR.
The last ownership-changing event predates issuance (Dec 2019); the patent issued 2021‑06‑22. I could not confirm any infringement suit naming the '344 patent within 6 months before its issuance. Bright Data's well-documented suit against Teso LT / Oxylabs asserted the sibling patents 9,241,044 ('044) and 9,742,866 ('866) — not the '344. Do not conflate those numbers. [The '044 patent above is US 9,241,044, unrelated to US 11,044,344.]

6. Bankruptcy fire-sale — NOT PRESENT. No bankruptcy of Web Spark Ltd, Luminati Networks Ltd, or Bright Data Ltd surfaced.

7. Privateering — NOT PRESENT. There is no evidence an operating company transferred this patent to a third-party NPE to assert on its behalf. Bright Data asserts its own patents in its own name.

8. Defensive aggregator — NOT PRESENT. The chain terminates at Bright Data Ltd, an operating commercial entity, not at RPX/AST/LOT/Unified/OIN.

---

Verdict

Operating-company assertion.

Justification: the recorded chain is inventors → Web Spark Ltd (2019‑10‑24) → Luminati Networks Ltd (2019‑12‑05) → Bright Data Ltd, change of name only (2021‑03‑31) — a founder-IP-entity feeding a single operating company that sells the practicing product (residential proxy / data collection) and has asserted its proxy patents against direct competitors (Teso LT/Oxylabs, BI Science) rather than against end users. None of the NPE markers (shell transfer, known asserter, cascading LLCs, privateering, defensive aggregator) are present, and the one signal I could not evaluate — repeat correspondent — is data-limited rather than negative. Two caveats must travel with this verdict: (i) Bright Data is a high-volume enforcer whose customer-directed demand letters drew explicit "patent bully" criticism from a competitor; and (ii) the assertion value is now effectively extinguished — IPR2022‑00353 rendered the claims unpatentable, the Federal Circuit affirmed (2025‑08‑01), and cert was denied (2026‑02‑23), so this patent is a dead enforcement asset notwithstanding Google Patents' stale "Active" status.

I'll research US Patent No. 11,044,344 directly, focusing on its cited prior art references. Let me run several targeted searches.

Let me search for the actual cited references and the IPR prior art.

Let me try to retrieve the patent's front-page "References Cited" section and confirm the IPR prior art set.

Prior Art Analysis — US Patent No. 11,044,344 B2

Important scope caveat up front (please read before relying on the tables below):

The user asked me to "look at each patent citation for 11044344" — i.e., the front-page (56) References Cited list. I was not able to retrieve that front-page list. The Google Patents full text that was fetched for this patent omits the "(56) References Cited" block, and my targeted retrieval queries kept returning the front pages of other, unrelated patents (e.g., US 11,344,413, US 10,205,291, WO 2013/032623 A3). I am therefore not going to reconstruct the examiner-cited list from memory, because doing so would violate the no-fabrication rule.

What I can give you, with citations, is the prior art of record that is legally dispositive for this patent — the references the PTAB actually relied on to hold its claims unpatentable in IPR2022‑00353, and which the Federal Circuit affirmed. That is the "most relevant prior art" for US 11,044,344 in the strongest sense. I flag precisely which items I verified and which I could not.

---

1. Confirmation of the patent (USPTO / Google Patents record)

Sources: https://patents.google.com/patent/[US11044344B2](/patent/US11044344B2)/en ; https://portal.unifiedpatents.com/ptab/case/IPR2022-00353

Because the earliest priority is 2009‑10‑08, the prior-art framework is pre‑AIA 35 U.S.C. § 102 (i.e., § 102(a), (b), (e)) — the Board's decision uses bare "§ 102" in its anticipation table.

---

2. Most relevant prior art (the IPR2022‑00353 record)

The Final Written Decision ("FWD", Paper 53, entered Sept. 22, 2023) was rendered in the consolidated family of proceedings. The Petitioner's reference set, as recited in the FWDs and reproduced in the Federal Circuit appendix and the Supreme Court petition appendix, was:

A. Crowds — the primary anticipating reference

• Full citation: Michael K. Reiter & Aviel D. Rubin, "Crowds: Anonymity for Web Transactions," ACM Transactions on Information and System Security (TISSEC), Vol. 1, No. 1, pp. 66–92, November 1998. (IPR Exhibit 1006, "Crowds.")
• Date: published Nov. 1998 — more than one year before the 2009‑10‑08 priority.
• Brief description: A system in which a user joins a "crowd" of users that "collectively issues requests on behalf of its members." A member's request is forwarded (routed) through at least one randomly chosen other member of the crowd before being submitted to the end web server, so the end server cannot identify the originating member. This is the reference the Board found discloses the "client device receives a URL from a second server → fetches the content over the Internet → returns the content to the second server" relay structure of the granted claims.
• § 102: potential anticipation. Crowds is the reference on which the Board's anticipation holding rests. The Federal Circuit (opinion filed Aug. 1, 2025) states: "the Board held that Crowds either anticipates the appealed claims or, in combination with other references or alone, renders them obvious." In the parallel family proceeding (IPR2022‑00916), the Board's table expressly maps § 102 anticipation by Crowds to claims 1, 6, 7, 15, 16, and 18–24. On the '344‑specific proceeding, the Board found Crowds controlling for the challenged independent/relayed‑fetch claims.
• Caveat: I could not pull the '344 FWD's own claim-by-claim § 102 table directly (the FWD PDF is access‑restricted / protective‑order material). The claim numbers just given are from the Board's table in the sibling IPR2022‑00916, reproduced in the Supreme Court appendix (Appendix E). Do not treat those claim numbers as automatically the '344's; verify against the '344 FWD.

B. Border — cited U.S. patent reference

• Full citation: Border, et al., U.S. Patent No. 6,795,848 B1 (IPR Exhibit 1012, "Border").
• Publication/issue date: September 21, 2004 (as recited in the record). (Filing date not captured in my sources — I am not going to guess it.)
• Brief description: I could not verify Border's disclosure content. It is listed as Petitioner's prior art exhibit in the family's IPR references and would be a § 102(e) reference (U.S. patent having an effective filing date before applicant's), but I have no verified summary of its subject matter. Treat the description as unverified.
• § 102: asserted by Petitioner as § 102/§ 103 art; the exact claim mapping I could not confirm.

C. MorphMix

• Full citation: Marc Rennhard, "MorphMix — A Peer‑to‑Peer‑based System for Anonymous Internet Access," 2004 (IPR Exhibit 1008, "MorphMix").
• Date: 2004 — before the 2009 priority date.
• Brief description: A peer‑to‑peer anonymity system in which anonymous tunnels are built through a network of peers (mixes), used to relay a user's traffic so the destination cannot identify the source. Conceptually the same "relay the request through another node before it reaches the end server" architecture.
• § 102: Petitioner's secondary/obviousness reference; combined with Crowds. I could not confirm a standalone § 102 anticipation mapping.

D. RFC 2616 (HTTP/1.1)

• Full citation: R. Fielding, et al., "Hypertext Transfer Protocol — HTTP/1.1," RFC 2616, IETF Network Working Group, June 1999 (IPR Exhibit 1013).
• Date: June 1999.
• Brief description: The HTTP/1.1 protocol standard (headers, caching semantics such as max‑age/no‑cache, conditional requests). Relevant to the claim elements reciting HTTP servers, HTTP requests, and returning pages/headers.
• § 102: Primarily an obviousness reference. One FWD in the family set found a group of claims "obvious over Crowds and RFC 2616."

E. RFC 1122

• Full citation: R. Braden (ed.), "Requirements for Internet Hosts — Communication Layers," RFC 1122, IETF, October 1989.
• Brief description: Host requirements for the Internet communication layers (relevant to the TCP/connection-layer limitations in some dependent claims).
• § 102/§ 103: Combined with Crowds; one FWD in the family set found claims "obvious over Crowds and RFC 1122."

F. Garcia — prosecution-history reference (citation not verified)

During prosecution of an ancestral application in this family, the applicant distinguished the invention from a prior-art reference referred to in the record as "Garcia." The Federal Circuit opinion quotes the applicant's statement distinguishing "client device" from "Garcia's server." I do not have Garcia's full citation (patent number / publication), and I will not invent one. This is worth pulling from the prosecution history if you need the complete examiner-cited set.

---

3. Claim-by-claim § 102 summary (as best supported by the retrieved record)

Net bottom line: the single most relevant anticipating reference for US 11,044,344 is Crowds (Reiter & Rubin, TISSEC Vol. 1, No. 1, Nov. 1998) under 35 U.S.C. § 102, with Border (US 6,795,848 B1), MorphMix, RFC 2616 and RFC 1122 as § 103 combiners. The Board's FWD (Paper 53, Sept. 22, 2023) and the Federal Circuit's Aug. 1, 2025 affirmance rendered the challenged claims unpatentable.

---

4. Discrepancies and flags (do not skip these)

1. Claim-count contradiction with the earlier-generated summary. The previously generated section states the '344 has two independent claims (1 and 24) and implies a ~24-claim patent. However, the FWD "ORDERED" paragraph I retrieved reads: "claims 1, 2, 6–11, 13, 16, 18–25, 29–34, 36, 39, and 41–46 of U.S. Patent No. 11,044,344 B2 have been shown to be unpatentable" — which implies at least 46 claims. Separately, one opinion‑below document states the '342 patent (11,044,342 — a different sibling, application 16/600,507) has 24 claims, claim 1 the only independent claim. I could not fully disentangle which claim list belongs to '344 vs. '342, because the retrieved "Opinion‑Below" PDF concatenates FWDs for both patents. This directly contradicts the earlier note that '344 has independent claim 24 and ~24 claims. Verify the '344 claim set from the USPTO PatentCenter / the FWD itself.

2. I did not retrieve the (56) front-page citation list. Everything above is the litigated prior art of record, not the examiner-cited list. If you need the examiner-cited set, pull the patent PDF front page (https://patentimages.storage.googleapis.com/.../US11044344.pdf) or USPTO PatentCenter for application 16/662,800.

3. Google Patents still shows legal status "Active" (anticipated expiration 2030‑07‑14). That label is contradicted by the PTAB/Federal Circuit outcome in IPR2022‑00353. Do not treat the Google "Active" label as controlling.

4. Documents surfaced by Google Patents' related-documents tables included US 7,203,741 B2 ("Method and system for accelerating receipt of data in a client‑to‑client network") and US 2002/0099566 A1 ("Wireless docking with out‑of‑band initiation"). The latter is plainly a machine-"similarity" artifact, unrelated to this subject matter. I could not confirm whether US 7,203,741 is an actual face-cited reference or also a similarity artifact — do not treat it as a verified citation. (US 7,203,741's subject matter, however, is conceptually adjacent to the '344 disclosure and is worth checking against the '344's (56) list.)

5. Distinct sibling patents — do not conflate. US 11,044,342 and US 11,044,344 are different patents in the same family. Also in the family: US 11,044,341, 11,044,345, 11,044,346, 11,050,852, 11,089,135, etc. The PTAB dockets IPR2022‑00103 ('342) and IPR2022‑00353 ('344) are different proceedings; prior-art lists overlap but their claim mappings are not interchangeable.

I could not retrieve either in full within this session.

I'll research the prior art referenced in this patent's record to ground the obviousness analysis.

Let me pin down the additional prior-art references named in the appellate record and the claim-by-claim grounds.

Let me retrieve the full claim set of the '344 patent and identify the "Garcia" reference cited during prosecution.

Obviousness Analysis — U.S. Patent No. 11,044,344 B2 under 35 U.S.C. § 103

Prepared: April 26, 2026
Patent at issue: U.S. 11,044,344 B2, System providing faster and more efficient data communication (app. 16/662,800; priority 2009‑10‑08)
Basis: The "Prior Art" data on the Google Patents page (source: https://patents.google.com/patent/[US11044344](/patent/US11044344)/en) plus the operative prior‑art record from IPR2022‑00353, the Federal Circuit opinion (Aug. 1, 2025), and the SCOTUS petition appendix volume (No. 25‑779).

---

0. What the "Prior Art" section of this page actually supplied — and what I had to supplement

I must flag this before analyzing, because it affects how much weight the analysis bears:

• The fetched Google Patents page for US11044344B2 gives only "Prior art keywords: server, web, client, internet, url" and "Prior art date: 2009‑10‑08." It does not contain a citation list of prior‑art references (no "References Cited" / "Cited By" table was present in the fetched HTML).
• The substantive prior‑art content on the page is therefore limited to (a) the Background of the Invention, which expressly characterizes the prior art in two categories — proxy servers (with Akamai named as a commercial example, and U.S.‑style deployment of proxies "deployed at every point around the world") and peer‑to‑peer file sharing (with BitTorrent named), and (b) the "Prior art date 2009‑10‑08" framing.
• Because a §103 analysis requires actual references, I supplemented the page using the prior‑art references that were actually applied to this patent and its siblings in the PTAB/U.S. District Court record. Those are identified below with citations, and I mark clearly which ones were applied to the '344 patent specifically versus to sibling patents in the same family.

Contradiction flag (carried forward, not resolved here): One excerpt of the IPR2022‑00353 Final Written Decision as indexed states that "claims challenged claims 1, 2, 6‑11, 13, 15, 16, and 18‑23 of the '344 patent are unpatentable," while the same decision's ORDER and its institution‑stage ground table omit claim 15. I treat the ORDER language ("claims 1, 2, 6–11, 13, 16, 18–25, 29–34, 36, 39, and 41–46") as authoritative and treat the "15" as an indexer/transcription artifact. Claim 15 does appear in the sibling '342 patent's claim set, which is a plausible source of the mix‑up.

---

1. Governing law and the effective filing date

• The claims carry an effective filing date of 2009‑10‑08 (provisional 61/249,624). Because that date precedes March 16, 2013, the PTAB applied pre‑AIA 35 U.S.C. §§ 102(b)/103(a). The FWD's ground table confirms this: the Crowds anticipation ground is under §102(b) and all combination grounds are under §103(a). Any §103 analysis of this patent must therefore be conducted under pre‑AIA law, with the reference date being one year before 2009‑10‑08, i.e., references published before 2008‑10‑08 are §102(b) art.
• The controlling framework is the Graham v. John Deere, 383 U.S. 1, 17–18 (1966) four‑factor inquiry (scope/content of prior art; differences; level of ordinary skill; objective indicia), as refined by KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007). The FWD recites exactly this framework (see https://fedcircuitblog.com/wp-content/uploads/2025/09/Opinion-Below-Bright-Data.pdf).
• Every reference discussed below is comfortably §102(b) art against a 2009 priority date: Crowds (Nov. 1998), Border (Sept. 2004), MorphMix (2004), Plamondon (pub. Sept. 2008), RFC 2616 (June 1999), RFC 1122 (Oct. 1989), RFC 791 (1981), RFC 1180 (1991).

2. Claim scope — what must be taught or suggested

2.1 Independent claims

Claim 1 (method, by a "first client device"):

• (1a) communicating with a second server;
• (1b) receiving, from the second server, the first URL;
• (1c) sending, to the web server over the Internet, the first URL;
• (1d) receiving the first web‑page from the web server over the Internet in response to (1c); and
• (1e) sending the received first web‑page to the second server, in response to the receiving of the first URL.

Claim 24 (method, by a "first device") — the same relay repeated across two target web servers (first URL → first web server; second URL → additional web server).

2.2 Dependent claims whose substance is recoverable from the record

Scope note / caveat: I could not retrieve the literal text of claims 18–25, 29–34, 39, and 41–46. My analysis treats them as dependents of claim 1 or 24 whose added limitations are addressed by the same references; the FWD's ORDER (not my reconstruction) is what establishes that they were held unpatentable.

2.3 Construction the claims received (critical to the §103 mapping)

The Board construed, and the Federal Circuit affirmed on Aug. 1, 2025:

• "client device" = "a communication device that is operating in the role of a client" (role‑based, not hardware‑based);
• "second server" = "a server that is not the client device" / "a device that is operating in the role of a server" that is not the first client device.

This matters enormously for obviousness: Bright Data's non‑obviousness theory was that the prior art's nodes were all "generic user computers," so no reference disclosed a structurally distinct client device/consumer computer cooperating with a commercial server. The Board rejected that construction; the Federal Circuit affirmed. The §103 analysis below is therefore run under the affirmed role‑based constructions, which is the posture in which the claims were invalidated (Bright Data Ltd. v. Code200, UAB, No. 2023‑2144 et al.; https://www.courtlistener.com/opinion/[10646198](/patent/10646198)/bright-data-ltd-v-code200-uab/).

---

3. Level of ordinary skill in the art (POSA)

Consistent with the Board's assessment, a POSA at the 2009 critical date would have had a bachelor's degree in computer science, electrical engineering, or equivalent, plus about two years of experience in network communications — or equivalent work experience — with working knowledge of: HTTP per RFC 2616, TCP/IP per RFC 793/1122, web caching and cache validation, client/server and proxy architectures, and peer‑to‑peer/anonymity overlay networks. This matters because most of the combination grounds rest on HTTP and TCP standards knowledge that a POSA was required to have, not on obscure art.

4. The prior‑art references

4.1 Applied to the '344 patent in IPR2022‑00353 (the operative references)

Ground table as instituted (IPR2022‑00353, Paper 8):

Source: https://bannerwitcoff.com/wp-content/uploads/2023/07/IPR2022-00353.pdf

4.2 Family‑level references (applied to sibling patents; available as combinable art for the '344 claims)

Sources: https://www.docketalarm.com/cases/PTAB/IPR2021-01492/NetNut_Ltd._v._Bright_Data_Ltd/ (Teruya exhibit list identifying Crowds, MorphMix, Border US 6,795,848, RFC 2616, RFC 791, RFC 1122); https://bannerwitcoff.com/wp-content/uploads/2023/10/IPR2021-01493.pdf

---

5. Element‑by‑element: Crowds as the primary reference for claim 1

Crowds discloses grouping users into a crowd that "collectively issues requests on behalf of its members." Each user runs a jondo process on her computer; jondos are organized into random paths; the request travels jondo→jondo until an end jondo submits it to the target web server; "server replies traverse the same path as the requests, only in reverse." Figure 2's paths include 5 → 4 → 6 → server. The Board adopted the petitioner's mapping (annotated Fig. 2):

For claim 24 (second/additional web server), Crowds supplies the teaching directly: "subsequent requests initiated at the same jondo follow the same path (except perhaps going to a different end server)," and jondos parse HTML replies to identify and fetch automatically requested URLs (embedded images, etc.) from other end servers.

For claim 6 (third server / second URL), the Board used Crowds' other path 3 → 1 → 6 → server 3: jondo 6 (first client device) receives a URL originating at jondo 3, forwarded via jondo 1, and sends that URL to web server 3 over the Internet.

The Board also held that the "over the Internet" limitation was, at minimum, an obvious alternative: a POSA would have understood Crowds' WWW transactions to operate over the Internet (Pet. 27), and that the disclosed jondos inherently communicate over Internet links.

Conclusion on Crowds alone: claims 1, 2, 6, 7, 16, 18–23 were found anticipated; claims 1, 2, 6, 7, 16, 18–25, 29, 30, 39, 41–46 were found obvious over Crowds alone. Single‑reference obviousness is proper where the reference teaches the limitations and a POSA would have had reason to implement the claimed subject matter from that teaching (KSR; In re Baxter Travenol Labs.).

6. The §103 combinations and the motivation to combine

Combination A — Crowds + RFC 2616 (claims 10, 11, 13, 33, 34, 36)

What RFC 2616 adds: (i) HTTP/1.1 caching semantics, including cache validators, conditional requests, and the 304 "Not Modified" special status code (§§ 13, 14.9); (ii) cache‑control directives (max‑age, no‑cache) that the patent's own specification mirrors; (iii) persistent connections as the default; (iv) message headers generally; and (v) the GET method for retrieving any resource, including an executable.

Motivation (as the Board credited):

1. Same field, necessary implementation knowledge. Crowds is a system for carrying out web transactions; HTTP is the protocol those transactions use. A POSA developing software for web‑transaction applications "would have had a powerful motivation to combine its disclosure with knowledge of Internet standards governing HTTP" (Teruya Decl. ¶ 106). This is the classic "a reference must be implemented according to its governing standard" rationale.
2. Caching improves the very metric Crowds degrades. RFC 2616 caching "significantly improve[s] performance" by "eliminat[ing] the need to send requests in many cases, and … eliminat[ing] the need to send full responses in many other cases." Crowds is a latency‑adding overlay; adding HTTP caching to jondos produces the predictable, beneficial result of reducing both latency and bandwidth — a design incentive squarely within KSR.
3. Claim 10/11/33/34 mapping. In RFC‑2616‑modified Crowds, jondo 6 sends a conditional request containing the cached page's cache validator to web server 5; if the page is unchanged, jondo 6 receives a 304 with the "special status code." That is the claimed "determining that the received first content is valid" and "based on the received HTTP header according to… RFC 2616."
4. Claim 13 mapping. The Board accepted that Crowds' authors' express desire to widely distribute the jondo application makes it obvious that the jondo software would be "resident on jondo 6 after downloading same over the Internet and then installing same on the device" — i.e., the claimed "downloading, by the first client device from the Internet, the software application," with the application's instructions causing the processor to perform the claimed sending. Separately, a POSA would have found "send‑stored‑content functionality" advantageous "because it sped up web access times."

Result: claims 8, 9, 31, 32 (with RFC 1122) and 10, 11, 13, 33, 34, 36 (with RFC 2616) held obvious.

Combination B — Crowds + RFC 1122 (claims 8, 9, 31, 32)

What RFC 1122 adds: the TCP/host requirements layer, including TCP keep‑alive mechanisms and link‑layer (ARP/MAC) addressing context.

Motivation: Crowds relies on static, persistent paths that last more than one transaction (a jondo's path is deliberately kept stable to preserve anonymity against the predecessor attack). A POSA implementing that architecture would "have been motivated to implement TCP keep‑alives on Crowds' jondos to detect when a peer jondo has crashed and to prevent termination of the TCP connection due to inactivity." This is the paradigm of a known technique (keep‑alives) applied to a known, identified problem (silent peer failure / idle teardown) in a predictable way — KSR's "combination of familiar elements according to known methods." Result: claims 8, 9, 31, 32 obvious.

Combination C — Crowds alone (§103) for the remaining claims

For claims 18–25, 29, 30, 39, 41–46 the Board held that Crowds by itself rendered the claims obvious, relying on the anticipation mapping plus the "over the Internet" alternative rationale for limitation 1[c] and on Crowds' express statement that subsequent requests may go to different end servers for claim 24.

Combination D — MorphMix + RFC 2616 (and MorphMix alone) — the family‑level analogue

MorphMix (2004) teaches a peer‑to‑peer mix network in which "[e]very node joining the system can itself establish circuits via other nodes to access a server anonymously, but can also be part of circuits established by other nodes and relay data for them at the same time," with virtual links over TCP between neighboring nodes and anonymous tunnels via intermediate nodes to a server. Mapped to claim 1: node (c) (last node before the server) = "first client device"; intermediate node (b) = "second server"; server (s) = the web server. The Board held claims 1, 6–8, 13, 15, 16, 18–24 anticipated by MorphMix and claims 1, 6, 8–11, 13, 15–20, 22–24 obvious over MorphMix + RFC 2616 in the sibling '510 patent. Motivation: the identical one — MorphMix is a web‑access anonymity overlay, and its implementer must use HTTP and HTTP caching to make web browsing work efficiently.

Combination E — Border + RFC 2616 (and Border alone)

U.S. 6,795,848 (Border, 2004) discloses an intermediary network appliance architecture that receives and relays content, and was held to anticipate claims 1, 6, 10, 15–20, 23, 24 of the sibling '510 patent, and (with RFC 2616) to render claims 1, 6, 8–11, 13, 15–20, 22–24 obvious. Border is useful here as an independent, structurally distinct primary reference: it shows that a network appliance relaying HTTP content between an upstream source and a downstream requester was known, which forecloses any argument that "relaying fetched web content back to a requesting server" was novel per se.

Combination F — Plamondon + {RFC 2616, RFC 1122, IEEE 802.11‑2007, Price, Kozat}

US 2008/0228938 (Plamondon) was applied in the sibling '319 IPR (IPR2022‑00135) in these specific combinations:

• claims 15–17 obvious over Plamondon + RFC 2616 (HTTP semantics/validity);
• claims 17–18 obvious over Plamondon + RFC 1122 (TCP layer);
• claims 6–11 obvious over Plamondon + Kozat (content/chunking);
• claims 2–5, 19–20 obvious over Plamondon + Price;
• claim 2 obvious over Plamondon + IEEE 802.11‑2007 (the MAC‑address element of claim 2 — an 802.11 MAC address is, by definition, a MAC address, and the POSA knew it).

This is significant for the '344 analysis because it demonstrates that each individual "secondary" limitation of the '344 claims — MAC addressing, TCP keep‑alives, HTTP validity checks, software delivery — was the subject of a separately documented, pre‑2009 combination in the same field, i.e., each was a known technique with known benefits, not an inventive contribution.

Combination G — Mithyantha (appliance/proxy) — caution

US 2009/0037977 ("Mithyantha") discloses appliances 200/200a/200b that act as "a proxy or access server," with a request routed through a first appliance and then a second appliance to a server. Because its publication date (Jan. 2009) is after the 2009‑10‑08 priority date, it is not §102(b) art against the '344 claims and is usable in a §103 analysis only if the relevant claim's effective filing date is the 2019 application filing date. I flag it as not available for the 2009‑priority claims without a specific 102(e)/103 analysis and a different priority‑date conclusion. Do not treat Mithyantha as a §102(b) reference against these claims.

7. Motivation to combine — the affirmative case, and the rebuttal of teaching‑away

Affirmative rationales (KSR‑recognized):

1. Same field of endeavor / same problem. Crowds, MorphMix, Border, the '344 patent's own Background (proxies; Akamai; peer‑to‑peer/BitTorrent), and RFC 2616 are all directed to moving web content between a requester and an origin server through an intermediary over the Internet. Rational combination is presumed among references in the same field addressing the same problem.
2. Standards‑compliance rationale. A system that carries web transactions must speak HTTP; the reference implementation of HTTP/1.1 is RFC 2616, and the TCP‑layer requirements are RFC 1122. Applying a mandatory standard to a disclosed system is not an inventive act.
3. Known techniques solving identified problems, with predictable results. Caching (RFC 2616 §13) → reduces requests and latency; keep‑alives (RFC 1122) → detects dead peers and prevents idle teardown; 304/conditional requests → validates cached content without a full transfer. Each yields only the expected benefit.
4. Design incentive / market pressure. The patent's own Background documents the recognized need: more video on demand, globally served web sites, ISP infrastructure cost pressure, and the resulting "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." That is an express statement of the long‑felt need that supplies motivation for combining distributed‑relay art (Crowds/MorphMix/Border) with HTTP efficiency art (RFC 2616/1122).
5. Predictable, finite number of identified solutions. Given jondos that relay web content, the available efficiency levers were (i) cache at the jondo, (ii) keep the HTTP/TCP connection alive, (iii) validate rather than re‑fetch. All three were known and all three produced the expected result.

Bright Data's teaching‑away arguments — and why the Board and Federal Circuit rejected them:

This is important: every teaching‑away theory Bright Data advanced was tied to the hardware‑based construction the Federal Circuit rejected. Under the affirmed constructions, the references' identical user computers are capable of being, at different times, the "first client device" and the "second server," exactly as the '344 claim 1 itself requires (the first client device acts as a client in steps 1[c]–[d] and as a server in step 1[e]).

---

8. Prosecution‑history references (Garcia / Harrow / Kocherlakota) and their §103 significance

During prosecution of the ancestral '936 patent (a great‑grandparent), the applicant distinguished a combination of Garcia + Harrow with these statements:

• "The Garcia disclosure is silent, and effectively teaches away, from caching or retrieving information objects from clients, such as by using peer‑to‑peer scheme."
• "The Garcia reference only teaches caching in servers or backbone‑embedded Web routers," and "caching information in clients clearly changes the way of operation of the Garcia reference."
• "[T]he devices described by Harrow are communicating over Local Area Network (LAN) using peer‑to‑peer scheme. Using clients over the Internet as both cache‑servers AND clients is clearly an unexpected result."

Bright Data later invoked these statements in the IPRs as a prosecution disclaimer supporting hardware‑based constructions. The Board found that the '936 prosecution "is for a great grandparent of the '344 patent and also involved evolving claim term amendments," that the claims under examination recited "device," "client communication device," and "client(s)" rather than "client device," and therefore that the '936 prosecution history was "less pertinent to the construction of the '344 patent claims than the claim language and Specification of the '344 patent itself." The Federal Circuit affirmed. Bright Data's rehearing petition (Aug. 29, 2025) and its cert petition (No. 25‑779) pressed this "asymmetrical disclaimer" theory; rehearing was denied and cert was denied. On the record as it now stands, the Garcia/Harrow prosecution argument does not defeat the obviousness case — but note that its substantive teaching‑away assertion (Garcia only caches in servers, not clients) is a different point from the disclaimer point, and it was not squarely accepted or rejected as a §103 teaching‑away in the '344 FWD. If you need that argument evaluated on its merits, it must be raised against a specific combination — e.g., one using Garcia as the caching reference — not against Crowds.

9. Claim‑by‑claim conclusions (as established in IPR2022‑00353)

Claims 3–5, 12, 14, 15, 17, 26–28, 35, 37, 38, 40 were not challenged in IPR2022‑00353 (a residual set whose literal text I could not retrieve). Because claims 3–5, 12, 14, 15, 17 are dependents of claim 1 (and 26–28, 35, 37, 38, 40 likely dependents of 24 or 25), their validity would rise or fall with their independent claims under pre‑AIA §103 practice — but I have not verified their dependency structure and flag that as unconfirmed.

---

10. Objective indicia (secondary considerations) — no nexus

The Board considered and rejected Bright Data's evidence of commercial success, long‑felt need, copying, and industry praise, on the ground that there is no nexus between the evidence and the claims. The evidence reflected the marketplace success of "residential proxy service[s], residential consumer computers, and residential IP addresses" — features not recited in any claim. As the Federal Circuit put it: "The product neither embodies nor is coextensive with the challenged claims." The Board also rejected the argument that the '344 patent's specification's stated need for a new method of transfer established a recognized long‑felt need attributable to the claimed subject matter. The Federal Circuit affirmed these findings as supported by substantial evidence.

Consequence for a current §103 analysis: absent a new nexus theory tying specific evidence to specific claimed limitations, objective indicia do not overcome the strong prima facie case on these claims.

---

11. Bottom line on obviousness

Under the affirmed role‑based constructions, the '344 claims are obvious over the following combinations, with the motivations identified:

1. Crowds alone — obviousness for claims 1, 2, 6, 7, 16, 18–25, 29, 30, 39, 41–46 (single‑reference obviousness; Crowds' jondo‑to‑jondo relay paths map 1:1 to the claimed client‑device‑as‑relay steps, and Crowds expressly contemplates requests going to a different end server).
2. Crowds + RFC 2616 — obviousness for claims 10, 11, 13, 33, 34, 36 (HTTP caching/conditional requests supply the "validity determination"; Internet software download supplies claim 13's downloading step), motivated by Crowds' web‑transaction context and by HTTP caching's known performance benefit against Crowds' latency cost.
3. Crowds + RFC 1122 — obviousness for claims 8, 9, 31, 32 (keep‑alives for crash detection and idle‑teardown prevention on Crowds' deliberate persistent paths).
4. MorphMix (+RFC 2616) and Border (+RFC 2616) — independent primary references teaching the same intermediary‑relay architecture, available as alternative or cumulative combinations against claims 1 and 24.
5. Plamondon + {RFC 2616 / RFC 1122 / IEEE 802.11‑2007 / Price / Kozat} — demonstrating that the dependent‑claim subject matter (MAC addressing, TCP keep‑alives, HTTP validity, chunking) was each separately known.

The decisive legal realism caveat: the §103 question here is not hypothetical. The PTAB reached precisely these conclusions, and the Federal Circuit affirmed on August 1, 2025; panel rehearing/en banc rehearing was denied on October 1, 2025; and certiorari was denied (reported February 23, 2026). Under the current record, the claims of US 11,044,344 are invalid for obviousness (and, for many claims, also anticipated), notwithstanding the "Active" legal‑status label shown on the Google Patents page.

12. Explicit uncertainties / things I could not verify

1. The "Prior Art" section of the patent page contains no reference list. All operative prior‑art references above come from the PTAB/CAFC record, not from the page's own citation data. If the page's "References Cited"/"Cited By" tables exist in the dynamic version, they were not present in the fetched HTML I was given.
2. Claim 15 discrepancy. The FWD's ORDER omits claim 15 from the set of claims held unpatentable, but one indexed excerpt of the same decision includes it. I have treated the ORDER as authoritative. Claim 15 text ("receiving, by the first client device from the second server over the established TCP connection, the first URL") appears in the '342 sibling's FWD excerpts.
3. Literal text of claims 3–5, 12, 14, 15, 17, 26–28, 35, 37, 38, 40 was not retrieved. I did not reconstruct it.
4. Exhibit numbering varies by IPR. In IPR2022‑00353, Crowds = Ex. 1004 and (per the FWD citations) the '344 patent = Ex. 1002; in IPR2021‑01492 (NetNut), Crowds = Ex. 1006, Border = Ex. 1012, MorphMix = Ex. 1008, RFC 2616 = Ex. 1013, RFC 1122 = Ex. 1016. Do not cross‑read exhibit numbers between proceedings.
5. Mithyantha's availability. Publication date Jan. 2009 is after the 2009‑10‑08 priority date; I have flagged it as unavailable for the priority‑date claims absent a separate priority analysis.
6. "Border" identification. I identify Border as U.S. Patent No. 6,795,848 B1 to Border et al. (Sept. 21, 2004) based on the NetNut/Code200 exhibit lists. I did not independently read the Border patent's specification; the mapping of Border to the '344 claim elements would need that review.
7. No district‑court infringement case on the '344 patent (per the prior litigation summary in this file and the PTAB record), so there is no Markman record specific to the '344 patent independent of the Teso/Code200/NetNut orders that the Board adopted.
