Summary: US Patent 11029903 (US11029903B2)

Bibliographic Data

Abstract (verbatim): "Output systems (e.g., television controllers, audio output devices, display devices) for accessing digital content from a service provided by one or more servers over the Internet are herein disclosed and enabled. To receive and play the digital content, the output system may obtain authentication information for accessing the service, receive a list of digital content that are available from the service for selection at the output system, receive output data from the service related to the selected digital content, and then play either audio data or video data, which is related to the received output data, at an output device coupled to the output system. The output system may further implement a discovery operation for a client device (e.g., smart phone or information pad), which is in the same network as the output system, to wirelessly discover the output system for providing output service to the client device."

The patent has 20 claims, with three independent claims: 1, 8, and 15.

Plain-Language Overview of the Independent Claims

Claim 1 — Method for outputting digital content at an output system (e.g., a controller box wired to a TV).
A method in which an output system (having processors, an IEEE 802.11-compatible wireless chip/chipset, a user interface, and a wired connection to an output device such as a television) (1) obtains authentication info for a server-based Internet service; (2) wirelessly joins a WLAN via the 802.11 chip; (3) connects over that WLAN to the servers; (4) sends a "job object" containing the authentication info to access the service; (5) accesses the service; (6) receives the user's selection of digital content; (7) sends a "digital document object" containing a pointer/reference to the selected content; (8) wirelessly receives output data (audio/video) back from the servers; (9) processes it into audio/video output data (e.g., decode, convert, scale); and (10) delivers it over the wired connection to the output device for playback. The claim further requires the output system to run a wireless discovery operation so that a separate client device (e.g., smart phone) in the same WLAN can discover the output system for output service, and to wirelessly receive audio/video content from that client device over the WLAN.

Claim 8 — A wireless output device (e.g., a smart TV, speaker, or controller box).
An apparatus claim covering a wireless output device with operating-system software (facilitating app download/installation), processors, a user interface, and 802.11-compliant wireless communication units with radio-frequency link controllers. The device: (1) couples to a WLAN; (2) connects to servers over the Internet; (3) sends a job object containing authentication, payment, and/or subscription info to access the service; (4) accesses the service; (5) obtains a list of available content for user selection; (6) receives the user's selection; (7) sends a "digital content object" with a pointer/reference to the selected content; (8) receives audio/video output data from the servers; and (9) stores/queues/spools that output data. The device must also broadcast its availability for discovery by a client device in the same WLAN and wirelessly receive audio/video content or digital documents from that client device for playback at the wireless output device.

Claim 15 — An output system (system claim).
An apparatus claim covering an output system with operating-system software, processors, a user interface, and wireless chips/chipsets (802.11-compatible). Execution of the OS causes the system to: (1) couple to a WLAN; (2) establish a wireless connection to servers over the Internet; (3) obtain identification/subscription info; (4) send a job object containing that info to access the service; (5) access the service; (6) receive the user's content selection; (7) send a "digital content object" with a pointer/reference; (8) receive audio/video output data; and (9) process it into playable audio/video output data. The OS additionally causes the system to broadcast its availability (while waiting for discovery), transmit at least one identification attribute to the discovering client device, and wirelessly receive audio/video digital content from that client device in the same WLAN for playback at the system or a connected output device.

CAFC 2026 Docket Search — Result and Uncertainty

I searched for CAFC 2026 docket activity on the literal number 11029903 and found no Federal Circuit appeal records in 2026 tied to this patent. My searches on that specific identifier returned no CAFC docket results. I cannot confirm or rule out a 2026 CAFC appeal; the publicly indexed material I found covers only district-court and PTAB matters (below). If a CAFC 2026 docket exists, it was not surfaced by my searches, and you should verify directly in PACER/CAFC CM/ECF.

Known Litigation Activity (non-CAFC, from Google Patents / Unified Patents / PatSnap)

• PGR2021-00112 (PTAB) — Post-grant review petition filed by Unified Patents; Google Patents labels the matter "Settlement."
• 6:21-cv-00680 (W.D. Tex.) — District-court case involving the patent (per Unified Patents data).
• 2:23-cv-00616 (E.D. Tex.) — Flexiworld Technologies, Inc. v. Sony Corp., filed Dec. 19, 2023, before Judge Rodney Gilstrap; US11029903B2 was one of seven asserted patents (alongside US9836259B2, US11096056B2, US9798516B2, US9042811B2, US10768871B2, US10162596B2). Dismissed with prejudice by joint stipulation under Rule 41(a)(1)(A)(ii) on May 29, 2025, each side bearing its own costs — no merits ruling on infringement or validity.
• 2:26-cv-00229 (E.D. Tex.) — A 2026 district-court filing listed on Google Patents referencing the patent (per Unified Patents data). This is a district court case, not a CAFC appeal.

Confidence note: The bibliographic data, abstract, and claim text above are drawn directly from the authoritative Google Patents record and uspto.report mirror of the USPTO grant, and are consistent across sources. The only item for which I lack authoritative confirmation is any 2026 CAFC docket activity, which my searches did not locate.

I'll search litigation databases for the specific patent number.

Good initial results. Let me dig into the specific cases found and search for others.

Litigation Involving U.S. Patent No. 11,029,903 ("the '903 patent")

Bottom line: The '903 patent (Flexiworld Technologies, Inc.) has been asserted in four known U.S. district-court litigations (W.D. Tex. 2021; N.D. Ga. 2022 [transferred from E.D. Tex.]; E.D. Tex. 2023; E.D. Tex. 2026), and was the subject of one PTAB post-grant review (PGR2021-00112), which was terminated by settlement. No Federal Circuit appeal involving the '903 patent was found.

Negative / "not found" results

• Federal Circuit: No CAFC appeal, docket, or decision involving US11029903 was located (2021–2026). This is consistent with the prior section's finding and with the fact that the Roku and Sony cases ended in stipulated dismissals and the PGR settled (no adverse final written decision to appeal).
• Flexiworld v. LG Electronics, Inc. et al., No. 2:25-cv-00960 (E.D. Tex., filed September 18, 2025): the publicly reported asserted-patent list is U.S. Pat. Nos. 9,042,811; 9,836,259; 9,965,233; 10,140,072; 10,162,596; and 10,037,178 — the '903 patent does not appear on that list. I therefore do not attribute the '903 patent to the LG case. (If additional patents were added by amendment, that would need to be confirmed from the PACER docket.)
• Stanford NPE Litigation Database currently lists only one case for patent 11029903 (Flexiworld v. Sony, 2:23-cv-00616), so that database is incomplete relative to Google Patents/Unified Patents and the J-EX/PACER records above.
• I did not find any ITC (Section 337) investigation involving the '903 patent.

Contradictions with the previously generated section (flagged per instructions)

1. PGR2021-00112 petitioner. The prior section states the petitioner was Unified Patents. The authoritative PTAB filings show the petitioner is Roku, Inc., and the proceeding was terminated by a Roku–Flexiworld patent license agreement. Unified Patents appears only as a data source hosting the PTAB record on its portal. The prior section's attribution is corrected here.
2. Case count for the '903 patent. The prior section described only three matters (PGR2021-00112; 6:21-cv-00680; 2:23-cv-00616) plus the 2:26-cv-00229 filing, omitting the Hisense litigation (1:22-cv-04337 et al., N.D. Ga.), where '903 claim 8 was expressly asserted. The complete list is five matters (four district-court + one PTAB).
3. Number of patents in the Sony case. The prior section lists seven asserted patents; patentpia's case record lists sixteen Flexiworld patents in connection with 2:23-cv-00616. These may reflect the complaint vs. the full case/portfolio listing; the discrepancy is unresolved on the records I retrieved.
4. Date inconsistency. The task states a current date of April 26, 2026, and the system date is September 15, 2026. One retrieved Korean news item carries a publication date of 2026-09-04. I have reported docket facts as of the latest retrievable entries (April 16, 2026 for the TCL case) and note the discrepancy rather than reconciling it.
5. Legal status label. Google Patents labels US11029903B2 "Expired – Fee Related" with anticipated expiration November 1, 2021 — a data label, not a legal conclusion, and it is in tension with the patent having been actively asserted in 2022–2026. Treat with caution.

Confidence note: Case numbers, parties, jurisdictions, and outcomes above are drawn from PACER-derived dockets (Justia, PacerMonitor, UniCourt), the PTAB record, and litigation databases, and are generally consistent across sources. The exact original E.D. Tex. filing date for the Hisense action, the precise filing date of 6:21-cv-00680, and the final disposition of the Hisense case(s) are items I could not confirm with high confidence and should be verified directly in PACER.

I'll search for the PTAB proceeding referenced in the prior litigation data (PGR2021-00112) and check for any other AIA trials on this patent.

Significant finding — the petitioner was Roku, Inc., not Unified Patents as the prior section implied. Let me pull the petition grounds, institution decision reasoning, and check for any other AIA trials on this patent.

Let me nail down the institution decision reasoning and check for any Federal Circuit appeal.

Correction to the previously generated section (flagged before analysis)

The prior "Patent summary" section states: "PGR2021-00112 (PTAB) — Post-grant review petition filed by Unified Patents." That is incorrect. The petitioner in PGR2021-00112 was Roku, Inc., not Unified Patents. The "Unified Patents" string in the Google Patents family-litigation widget is a data-source attribution ("Unified Patents PTAB Data" by Unified Patents, licensed CC-BY-4.0) — it is not the petitioner name. Every primary document in the file (petition, patent owner response, termination decision) captions the case as ROKU, INC., Petitioner v. FLEXIWORLD TECHNOLOGIES, INC., Patent Owner. Unified Patents does appear elsewhere in the Flexiworld campaign (IPR2022-00775 on the '257 patent; ex parte reexam 90/014,721 on the '114 patent), but not on the '903 patent.

Proceedings overview

There is exactly one (1) AIA trial proceeding on US 11,029,903: 0 active, 0 with claims canceled, 0 with claims sustained, 1 terminated by settlement before any final written decision, 0 institution denials — meaning no claim of the '903 patent has ever been adjudicated on the merits by the PTAB, so a defendant today faces an entirely untested patent but also an entirely unestopped prior-art landscape: the institution decision that survived (and the sharp § 101 / § 112(a) theories behind it) are public and reusable, and because no FWD issued, no § 325(e) estoppel attached.

Flag on sourcing: The structured "PTAB proceedings on file" block reports zero AIA trials (USPTO ODP returned none at last ingest). Web research did surface one — PGR2021-00112, filed 2021-09-15 and terminated 2022-10-31. The ODP block should be treated as incomplete rather than as a true negative; the proceeding is well documented on PTAB E2E and in third-party dockets.

PGR2021-00112 — Roku, Inc. v. Flexiworld Technologies, Inc.

• Type: Post-Grant Review (35 U.S.C. §§ 321–329)
• Filed: 2021-09-15 (within the nine-month § 321(c) window from the 2021-06-08 grant)
• Status: Terminated-Settled (verbatim). Google Patents labels it "Settlement." Plain English: trial was instituted, fully briefed, and killed by settlement ~three weeks before the scheduled oral hearing — no final written decision, no claim cancelled, no claim upheld.
• Judge panel: Terrence W. McMillin, Christopher L. Ogden, and Brent M. Dougal (Dougal authoring the termination order). The docket also reflects a Panel Change Order dated 2022-05-06 and Unified's PTAB judge index lists Bryan F. Moore on a PGR2021-00112 panel, so the panel composition shifted during the trial; the panel of record at termination was McMillin–Ogden–Dougal.
• Petition grounds: Challenged claims 1–20 (all claims) on two statutory bases:
  1. § 112(a) — lack of written description (and, as framed, priority/effective-filing-date support). Roku's exhibits show the theory: Ex. 1005 was a "Redline Comparing Issued Claims 1-7 of '903 Patent to Originally Filed Application Claims 1-7," with Exhibits 1006 and 1010 being U.S. Appl. Nos. 10/053,765 and 10/016,223 — i.e., Roku argued the issued claims were not supported by the 2000/2001 priority applications (09/992,413 chain).
  2. § 101 — patent-ineligible abstract idea (Alice/Mayo Step 2A prongs one and two, and Step 2B). Ex. 1007 was the Pebble Tide LLC v. Arlo Techs. memorandum order invalidating related patents, which Flexiworld argued was "irrelevant."
     The patent owner response also addresses an argument styled "Petitioner's Reliance on Rivera" — the full citation of that authority/reference is not visible in the indexed papers I retrieved, so I am not characterizing it.
• Institution decision: Instituted 2022-03-24 (Paper 7; a contrary "March 14, 2022" date appears in the parties' joint motion to terminate — the docket and the Board's own order both say 2022-03-24, so I treat the March 14 recital as a typo). The Board made two threshold rulings that matter:
  • § 325(d) — declined to exercise discretion to deny. Flexiworld argued the same § 101 arguments had already been presented and overcome during prosecution of related U.S. Pat. No. 10,489,096 (the examiner withdrew a § 101 rejection). The Board distinguished the claims ("the '096 patent claims recite a touchscreen interface not recited in the '903 patent claims"; the '096 claims have the information apparatus performing the steps whereas "the '903 claims focus on the 'output device' as performing the patented steps"), found the arguments were not the same or substantially the same under Advanced Bionics Prong One, and expressly noted that Roku's written description challenge was never before the Office at all.
  • PGR eligibility — the Board proceeded to decide it and instituted, which necessarily means it credited Roku's showing that at least one challenged claim has an effective filing date on or after 2013-03-16 under AIA § 3(n)(1). (This is a logical inference from the fact of institution; the indexed excerpt of the institution decision cuts off mid-recitation of the legal standard, so I am not quoting a verbatim eligibility holding.) That inference is the single most consequential thing in this file for a defendant — see the strategic summary.
• Final Written Decision: None. Never issued. No claim of US 11,029,903 was cancelled, confirmed, or construed in a final decision. Any statement that the '903 patent "survived" or "was invalidated" in this PGR would be false.
• Settlement / termination: The parties executed a Settlement and Patent License Agreement on 2022-10-21, under which they agreed to dismiss the co-pending W.D. Tex. litigation with prejudice and to seek termination of this PGR (and of IPR2022-01112, -01113, -01114). Joint Motion to Terminate filed 2022-10-27 with authorization; a Joint Request to Keep Separate was filed concurrently. The Board terminated under 35 U.S.C. § 327(a) / 37 C.F.R. § 42.72 on 2022-10-31 without rendering a final written decision, and granted the request to keep the Settlement and Patent License Agreement (Ex. 2012) as confidential business information under § 327(b) and 37 C.F.R. § 42.74(c). Terms are confidential — do not assume the license is available to you; Roku's license is Roku's.
• Appeal: None, and none is possible. No FWD issued, so there is no appealable final agency action. No CAFC docket number exists for this proceeding. (Verify independently at PTAB E2E and CourtListener's Federal Circuit docket; my CAFC search was truncated by tool limits, but the procedural posture makes an appeal a null set.)
• Defensive value: This is a glass-half-full-for-the-defendant outcome. You get the Board's institution decision — which rejected Flexiworld's § 325(d) discretionary-denial argument and (by necessary implication) its "this patent isn't even PGR-eligible" theory — but you get no merits ruling, no claim construction, and no estoppel. Roku's § 112(a) priority/written-description exhibit set (the claim redline plus the '223 and '765 applications) is public and portable; you can repackage it. Flexiworld's core response brief, the Cooklev declaration, and the deposition transcript (2022-08-18) are also public — which means you can see exactly where Flexiworld's experts are soft. The Cooklev deposition is notably weak on the "what were device-specific drivers actually doing" thread, which is the factual spine of the written description defense.

Strategic summary

Claim-level status: all 20 claims are UNTESTED. Claims 1–20 were all challenged and all institution-instituted, but the case died in settlement before the Board reached the merits. There is therefore no canceled claim and no sustained claim on the '903 patent. There is also no PTAB claim construction — no panel has told you what "output system," "digital document object," "job object," or "wirelessly discover the output system" mean. That cuts both ways: Flexiworld cannot point to a PTAB win as a validity shield, and you cannot point to a PTAB loss to narrow the claims. Every merits argument is fresh.

Estoppel: essentially none, and that is the headline. Section 325(e)(2) estoppel (the PGR analogue of § 315(e)(2)) attaches only "after the issuance of a final written decision." No FWD issued, so no IPR/PGR estoppel bars anyone. Roku is free to re-file an IPR on the '903 (now that the PGR window has closed, only §§ 102/103 patent-and-printed-publication grounds are available), and so are you — subject to § 315(b)'s one-year bar from service of a complaint and § 325(d) discretion. Two caveats: (a) the confidential Roku–Flexiworld license may cover Roku's suppliers/privies and ODMs, so check whether your client sits in that shadow; (b) Roku's own re-filing would be constrained by its settlement agreement, not by estoppel. The most valuable untapped ground is the one the Board never reached on the merits: § 112(a) written description / priority. Roku's theory — that the issued '903 claims are not supported by the 09/992,413 / 10/016,223 / 10/053,765 priority chain — is fully preserved, publicly briefed, and was the argument Flexiworld could not dispose of at institution because it was never previously before the Office (which is precisely why § 325(d) failed for Flexiworld). Note that this same priority theory was necessary to Roku's PGR eligibility: PGR exists only for first-inventor-to-file patents, so Roku had to prove the '903 claims did not get the 2000/2001 effective filing date. That is a genuine two-front squeeze you should exploit — Flexiworld's damages case needs the 2000/2001 priority date, and its PGR-eligibility posture (which it lost at institution) needs the opposite.

Pattern signals. This is a coordinated, multi-front Flexiworld campaign in which Roku was the primary challenger and the proceedings terminated en bloc as part of one global October 2022 license: PGR2021-00112 ('903), IPR2021-00713 (US 10,740,066), IPR2021-00714 (US 8,989,064), and IPR2022-01112/-01113/-01114 were all tied to the same settlement; IPR2022-01267 (US 9,836,257, Roku) and IPR2022-00775 (US 9,836,257, Unified Patents) followed. On the '257 patent Unified lost — the Board held Unified failed to show claims 27 and 28 unpatentable under § 103 (panel: McMillin, Ogden, Dougal — the same three APJs who sat on the '903 PGR), so Flexiworld has a merits win to advertise in this family. A defensive aggregator (Unified) is in the chain for the family, but not for this patent; no aggregator has ever taken a merits shot at the '903. Flexiworld's counsel of record here (Nelson Bumgardner Conroy; lead counsel transitioned mid-case from Brent Bumgardner to C. Austin Ginnings) is a contingency-fee plaintiff-side firm that litigates hard — Flexiworld filed a full preliminary response, a full patent owner response, a 64-page § 101 brief, a sur-reply, and pro hac vice motions rather than folding. Do not expect a cheap early exit.

One open question worth flagging to your damages team. Google Patents lists the '903 patent as "Expired – Fee Related" with an anticipated expiration of 2021-11-01, which is the 20-year term measured from the 2001-11-01 filing of US 10/016,223. That calculation presumes the 2000/2001 priority chain — the very premise Roku attacked. If Flexiworld relies on that chain for term, the patent expired in November 2021 and post-expiration damages should be nil; if it does not, the patent may still be live but is squarely PGR/IPR-eligible. This is a status/term inconsistency in the public record that has never been adjudicated (no FWD, no reexam, no district-court ruling on the '903). Treat it as a high-value discovery and claim-construction target, not as a settled fact — and confirm current maintenance-fee status in USPTO Patent Center before relying on any expiration theory. Google's legal-status labels are assumptions, not legal conclusions.

Recommended next steps

1. There is no FWD to cite, because none exists. If anyone on your team has characterized this PGR as a validity win or loss for either side, correct it. The accurate one-liner is: instituted 2022-03-24 on § 112(a) and § 101 grounds against claims 1–20; terminated 2022-10-31 by settlement under § 327(a) with the agreement kept confidential under § 327(b) and 37 C.F.R. § 42.74(c); no final written decision; no claim cancelled or confirmed; no appeal.
2. Pull the full record from PTAB E2E. Specifically obtain Paper 1 (Petition + Bhattacharjee Decl., Ex. 1002), Paper 7 (Institution Decision, 2022-03-24), Paper 12 (Patent Owner Response + Cooklev Decl., Ex. 2009), Paper 14 (Petitioner's Reply), Paper 20 (Sur-Reply, 2022-10-14), and the 2022-08-18 Cooklev deposition transcript (Ex. 1013). Roku's § 112(a) priority theory and the Ex. 1005 claim redline are the highest-value recyclable assets; the Cooklev transcript is the highest-value impeachment asset.
3. If your client has been sued, watch § 315(b). The one-year bar runs from service of the complaint. Because the PGR is closed and the '903 issued in 2021, a new IPR (not PGR) is your vehicle — limited to §§ 102/103 on patents and printed publications. Your best non-IPR track is an ex parte reexamination or a § 112/§ 101 challenge in district court, since §§ 101 and 112 are unavailable in IPR. Note the family precedent: Unified's ex parte reexam 90/014,721 against US 10,346,114 was granted on substantial-new-question grounds (2021-05-11) — that is a proven path against this portfolio.
4. No trial-stage milestones are pending — the statutory one-year clock (§ 326(a)(11)) started at the 2022-03-24 institution and would have run to ~2023-03-24 with oral argument set for 2023-01-13. Both dates are moot. If a new proceeding is filed, budget institution by month six and FWD by month twelve from institution.
5. Subpoena-proof your settlement/privy analysis. Although the Roku agreement is confidential, the public Joint Motion confirms it "completely resolves all pending controversies between Roku and Flexiworld concerning U.S. Patent No. 11,029,903" and that the parties dismissed the W.D. Tex. case with prejudice. Determine whether your client (or a contract manufacturer) is a Roku privy or licensed entity — that determines whether the license is a defense, and whether Roku is foreclosed from being your petitioner.
6. Do not cite the Pebble Tide order (Ex. 1007) as if it decided anything about the '903. It invalidated different patents (US 10,261,739 and 10,303,411); Flexiworld called it "irrelevant," and the Board never ruled on it.

I'll research the assignment record for US11029903, starting with the original assignee's corporate history and any recorded transfers.

Key lead: a recorded assignment at Reel/Frame 028733/0064 covering Flexiworld patents. Let me dig into the specific chain for this application.

Now let me check for any post-issuance assignments and the NPE/asserter profile of Flexiworld.

Assignment & Ownership Analysis — US 11,029,903 B2 (App. 16/696,989)

Verification note up front: I was able to retrieve family-level assignment records (reel/frame citations quoted in Flexiworld's own federal complaints) but not a record that specifically names US 11,029,903 or application 16/696,989. Nothing below invents a reel/frame. Where a record covers a sibling patent in the same priority family, I say so explicitly. Verify the patent-specific record at USPTO Assignment Center (search by patent number 11029903) or the legacy mirror at https://assignment.uspto.gov/patent/index.html.

Inventors

Pattern assessment: No unusual inventor-departure pattern is discernible. To the contrary, the opposite of the classic fire-sale tell appears: Chang and Liu appear as inventors across many members of this family spanning 2000–2019 filings, and both remain the assignors on every recorded family assignment I could identify. There is no evidence of an inventor departing the assignee within 12 months of filing, and no evidence of an inventor-side retention of rights or a competing inventor-owned LLC. Both inventors are the grantors, never later grantees — consistent with founder-employees assigning into the company at (or near) filing.

Original assignee

Flexiworld Technologies, Inc. — Vancouver, Washington (assignee on the face of the '903 grant; listed by Unified Patents as assignee of record).

• Primary line of business: IP holding / licensing. Flexiworld operates a patent-portfolio website (flexiworld.com, including a categorized "Digital Wallet / Payment Patents" page) rather than a product catalog. I found no evidence of any commercial product shipped by Flexiworld embodying the '903 claims (TV controllers, wireless output devices, etc.).
• Current status: Appears to be operating as an ongoing licensing/assertion entity. It is not dissolved, not in bankruptcy that I could identify, and it was still asserting the '903 as owner as late as the 2023 Sony action. Third-party litigation databases flag its suits with an NPE = Yes indicator (e.g., GoldenCompass entry for 2:23-cv-00616 marking "Plaintiff includes NPE (Yes=1)").
• Litigation posture: Serial plaintiff against consumer-electronics defendants (Sony, Roku, Hisense, and others) across televisions, projectors, soundbars, and streaming devices.

Assignment timeline

Finding in one line: The chain is a single-step inventor→company assignment, replicated once per continuing application in the family. I found no post-issuance assignment, no security agreement, no name change, no merger, no release, and no transfer to a third-party licensing LLC naming this patent.

The public records I retrieved are family-level. Flexiworld's complaints plead the assignment for sibling patents as follows:

• Execution date not established / recording date not established — Reel 028733/0064

  • Conveyance: Assignment of assignors' interest (inventor assignment)
  • Assignor: William Ho Chang; Christina Ying Liu
  • Assignee: Flexiworld Technologies, Inc.
  • Correspondent: not retrieved (the complaint excerpt does not state it; I could not reach the underlying cover sheet)
  • Context: Initial acquisition — inventors assign the originating family asset to their own company. Confirmed for the '402 patent (US 7,609,402), a parent in this family, not for the '903 itself.
  • Source: Flexiworld v. Hisense complaint, ¶ 51, via RPX litigation document 15143102.

• Execution date not established / recording date not established — Reel 039816/0200

  • Conveyance: Assignment of assignors' interest
  • Assignor: William Ho Chang; Christina Ying Liu
  • Assignee: Flexiworld Technologies, Inc.
  • Correspondent: not retrieved
  • Context: Initial acquisition — same inventor→company pattern for the '596 patent. Confirmed for US 10,162,596, not for the '903.
  • Source: Flexiworld complaint, ¶ 66, E.D. Tex. 2:25-cv-00960 record.

• Execution date not established / recording date not established — Reel 042385/0202

  • Conveyance: Assignment of assignors' interest
  • Assignor: William Ho Chang; Christina Ying Liu
  • Assignee: Flexiworld Technologies, Inc.
  • Correspondent: not retrieved
  • Context: Initial acquisition, but note a distinctive feature — one reel/frame record covers multiple family members (cited for both the '072 and the '178 patents). The 042xxx reel series corresponds to recordings in roughly the 2023 timeframe, i.e., a single blanket family assignment recorded shortly before Flexiworld's December 19, 2023 Sony complaint. This looks like portfolio-wide assignment-record housekeeping by the same owner, not a change of ownership. I cannot confirm the '903 is among the properties in this record.
  • Source: Flexiworld complaint, ¶¶ 60 and 72, E.D. Tex. 2:25-cv-00960 record.

Absence finding: No assignment record naming US 11,029,903 B2 or application 16/696,989 surfaced in any source I could reach (Google Patents legal events, the Flexiworld complaint pleadings, Unified Patents' patent page for US-11029903-B2). Under your rule, that is itself the finding: the original assignee, Flexiworld Technologies, Inc., remains the owner of record, which is corroborated independently by Flexiworld pleading "Flexiworld is the owner and assignee of all rights, title, and interest" in suits naming this patent.

(The 042385/0202 record covers '072 and '178; it is not confirmed to name the '903. The "Family assigned to Flexiworld" entry is the inventor assignment at reel 028733/0064 confirmed for the '402 parent, with an execution year that I could not establish — treat that year label as approximate family context, not a recorded date.)

NPE / troll-pattern signals

1. Shell-entity transfer — NOT PRESENT. There is no transfer from an operating assignee to a licensing-only LLC anywhere in this chain. The patent went straight from the inventors to Flexiworld Technologies, Inc. (reel 028733/0064 for the parent; 039816/0200 and 042385/0202 for siblings). Flexiworld is the original assignee, not a downstream acquirer. This is the single most important structural fact here: the usual "operating company sells to shell, shell asserts" arc is absent.

2. Known asserter in the chain — PRESENT (strong). Flexiworld Technologies, Inc. is the current and original assignee and is tracked as a serial plaintiff. Unified Patents maintains a patent page for US-11029903-B2 under assignee "Flexiworld Tech Inc" and docketed PGR2021-00112 (2021-09-15; terminated 2022 by settlement) against it. Third-party litigation analytics flag Flexiworld's suits as NPE-originated (NPE = Yes for 2:23-cv-00616). Flexiworld is not on your enumerated list (Acacia, Marathon, IV, Wi-LAN, etc.), so treat this as "high-frequency plaintiff surfaced by Unified Patents" rather than an enumerated-list match.

3. Repeat correspondent across the chain — UNCLEAR / NOT ESTABLISHED. I could not retrieve the correspondent of record on any of the three family reel/frame entries. Per your rule, I will not imply an attorney finding without the name. This is the highest-value gap to close — pulling the cover sheets for 028733/0064, 039816/0200, and 042385/0202 would show whether one attorney/firm has handled every Flexiworld recording since 2004.

4. Cascading transfers — NOT PRESENT. One hop only (inventors → Flexiworld), repeated per continuing application. No chained LLCs, no <24-month cascade.

5. Pre-litigation transfer — NOT PRESENT (but a related timing pattern exists). No third-party transfer within 6 months of a suit, because there is no third-party transfer at all. However, the 042385/0202 blanket family recording falls in roughly the 2023 window, just before the December 19, 2023 Sony complaint — a same-owner re-recording ahead of assertion rather than a transfer. Flagged as a timing curiosity, not a transfer signal.

6. Bankruptcy fire-sale — NOT PRESENT / UNCLEAR. No bankruptcy proceeding involving Flexiworld was surfaced.

7. Privateering — NOT PRESENT. Privateering requires an operating company transferring to an NPE that asserts on its behalf. Flexiworld is the original owner and asserts on its own behalf; there is no upstream operating-company sponsor in this chain that I could identify.

8. Defensive aggregator — NOT PRESENT. The chain does not terminate at RPX, AST, LOT, Unified, or OIN. Note the inverse posture: Unified Patents is on the challenger side here (PGR2021-00112), not as a purchaser — this patent has not been neutralized by a defensive aggregator.

Verdict

NPE — moderate confidence.

Flexiworld Technologies, Inc. is at once the original assignee and the asserting party: the family assignment records (reel 028733/0064 for the parent, reel 039816/0200, and reel 042385/0202) run from inventors Chang and Liu to Flexiworld, and Flexiworld pleads ownership of all right, title, and interest while suing TV/projector/soundbar makers over this patent — with no product of its own evidenced in commerce and with PGR2021-00112 filed against the patent in September 2021. That is one strong signal (known asserter / non-practicing patent owner actively asserting), which by your rubric caps the call at moderate rather than high — the classic NPE patterning around this patent is unusually weak precisely because the transfer-chain signals (shell entity, cascading LLCs, pre-litigation transfer) are all absent: this is an NPE-by-construction, not an NPE-by-transfer. I could not retrieve correspondents of record or a reel/frame naming the '903 itself, so I do not claim the "repeat correspondent" or "shell LLC" findings.

Two discrepancies with the previously generated sections, flagged as instructed:

1. Expiration rationale. The prior section read Google's "anticipated expiration 2021-11-01 / Expired – Fee Related" as "consistent with maintenance-fee non-payment rather than full 20-year term." I read it differently: 2021-11-01 is exactly twenty years after the claimed non-provisional filing date of 2001-11-01 (App. 10/016,223), so it is most likely the statutory term end computed from the family's earliest non-provisional — meaning this continuation issued on June 8, 2021 with only ~5 months of term remaining, not a post-issuance fee lapse. I cannot fully confirm this without the term/terminal-disclaimer record, so treat it as a correction of reasoning, not a settled fact.

2. Sony asserted-patent count. The prior section described 2:23-cv-00616 as asserting "seven asserted patents" (then listed eight numbers). The GoldenCompass docket record for 2:23-cv-00616 lists fifteen patents against Sony, including 11029903. The count in the prior section appears understated.

Important preliminary notes (contradictions and scope limits)

Two contradictions with the previously generated section — flagged per your instruction:

1. Current date conflict. The system context for this session states today is 2026‑09‑15; this task states April 26, 2026. I cannot reconcile these. All "as-of" statements below are keyed to the source fetch dates, not to either date.
2. PGR petitioner identity conflict. The prior summary states PGR2021‑00112 was a Unified Patents petition "labeled Settlement." The Board's own institution decision and the PTAB docket state the petitioner is Roku, Inc. ("ROKU, INC., Petitioner, v. FLEXIWORLD TECHNOLOGIES, INC., Patent Owner," PGR2021‑00112, Patent 11,029,903 B2). The "Unified Patents" attribution in the prior summary appears to come from the Unified Patents portal that mirrors PTAB/litigation data, not from the petition itself. Search results control: petitioner = Roku, Inc.
3. Legal-status conflict. The prior summary says Google Patents lists "Expired – Fee Related" with anticipated expiration November 1, 2021. A later fetch of the same Google Patents page returned "Expired - Lifetime" with "Prior art date 2000-11-01." These labels disagree; Google's label is an assumption in any event.
4. Probable data artifact. A Unified Patents portal scrape returned "US-4602280-A – Weight And/or Measurement Reduction Preview System – Priority Date: 2000-10-31 – Assignees: Flexiworld Tech Inc." US 4,602,280 is a 1986 patent unrelated to Flexiworld. I read the identifier literally as instructed, but flag this as a scraping/labeling artifact and do not rely on it.

Scope limit you need to know before reading the prior-art section (stated plainly, not hedged): I was unable to retrieve the '903 patent's front-page "References Cited" list (the examiner-cited U.S. patent documents) from either Google Patents' citation table or the uspto.report mirror. My searches for that record returned no results (the uspto.report query returned an empty result set), and the Google Patents page content I retrieved contained only the bibliographic, family, classification, and description fields — not the "Patent Citations / Cited By" tables. I therefore cannot give you "each patent citation for 11029903" with per-reference § 102 mapping. I will not fabricate patent numbers to fill that gap. What I can give you — and what is arguably more probative — is the actual prior-art and prior-art-evidence record from the only merits proceeding ever instituted against this patent (PGR2021‑00112), retrieved verbatim.

The relevant record: PGR2021‑00112 (Roku, Inc. v. Flexiworld Technologies, Inc.)

Source: https://portal.unifiedpatents.com/ptab/case/PGR2021-00112 (case metadata); docket and institution decision at https://www.docketalarm.com/cases/PTAB/PGR2021-00112/Roku_Inc._v._Flexiworld_Technologies_Inc/docs/03-24-2022-Board/Institution_Decision__Grant-7-Institution_Decision__Grant.pdf

• Filed September 15, 2021; institution granted March 24, 2022 (35 U.S.C. § 324) on claims 1–20 of US 11,029,903 B2.
• Terminated October 31, 2022 — settled, on joint motion. No final written decision on any ground. Related district matter identified by the parties: Flexiworld Technologies, Inc. v. Roku Inc., No. 6:21‑cv‑00680 (W.D. Tex.).
• Panel: APJs Bryan F. Moore, Christopher L. Ogden, Brent M. Dougal (later McMillin added per panel-change order).

What the petition actually challenged (critical framing)

Reviewing the petition's exhibit list and table of contents, the asserted grounds were not §§ 102/103 prior-art grounds. They were:

• § 112(a) written-description / priority — i.e., whether claims 1–20 are entitled to the 2000/2001–2002 priority chain (Petitioner's Ex. 1006, the '765 application, U.S. Appl. No. 10/053,765; Ex. 1010, U.S. Appl. No. 10/016,223 ("223 application"); Ex. 1008, file history excerpts of Appl. No. 15/787,067; Ex. 1005, redline of issued vs. originally filed claims).
• § 101 patent eligibility — the petition's body argues, element by element, that "Claim 1 Recites Conventional Computing Devices," "Claim 1 Recites Conventional Wireless Communications," and "Claim 1 Recites Conventional Steps" (Steps 1–12 enumerated), citing Appendices B–R as evidence of the state of the art as of the 2000 priority date, not as anticipating art.
• PGR eligibility — Patent Owner's Response argues "THE '903 PATENT IS NOT ELIGIBLE FOR POST-GRANT REVIEW." (Roku's priority challenge under § 112 was the vehicle for arguing at least one claim's effective filing date falls on/after March 16, 2013.)

Patent Owner's Response is captioned: "The '413 Application and '903 Patent Provide Adequate Written Description for Claims 1‑20" and "The Claims Are Patent Eligible Under 35 U.S.C. § 101." Source: https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1548112](/patent/1548112)/download-documents

Also in the exhibit list: *Ex. 1007 — Pebble Tide LLC v. Arlo Techs., Inc., Memorandum Order Invalidating Related U.S. Patent Nos. 10,261,739 and 10,303,411.* This is the merits event closest to an invalidity holding on the family, and it is a § 101 ruling on related, different patents — not a § 102 holding on the '903 patent.

My inference, explicitly labeled as inference: the absence of any third-party prior-art patent from Exhibits 1001–1013 (the only two patent-application exhibits are Flexiworld's own '765 and '223 applications) strongly indicates Roku did not plead anticipation or obviousness. That is an inference from document structure, not a statement I can verify against the sealed/withdrawn petition text.

References that are prior-art-relevant, with candidate claim mapping

The petition's Appendices B–R are the only prior-art-capable references I could actually retrieve by identity. They were submitted as conventional-technology evidence. I map them to coinciding claim elements as a § 102 candidate analysis only — none was pleaded under § 102, and none was adjudicated.

§ 102 date feasibility under each priority scenario

Because the entire PGR turned on the priority question, the § 102 character of these references flips depending on the outcome:

• If the Nov. 1, 2000 priority holds (pre-AIA § 102 applies):
  • § 102(b) (printed publication > 1 year before Nov. 1, 2000 → before Nov. 1, 1999): Appendices G (1997), K (1998), O/P (May 1998), N (Feb. 1999), J (Jan. 19, 1999), B (1999), L (July 21, 1999). These are the only Appendices solidly available as § 102(b) art.
  • § 102(a) only (published before Nov. 1, 2000 but within one year): Appendices D (Feb. 2000), M (Apr. 18, 2000), Q (Sept. 13, 2000), E (Sept./Oct. 2000), C (Oct. 30, 2000), and App. H/I depending on exact 1999/2000 printing.
  • Not prior art on this branch at all: Appendices F (2001) — post-dates the priority date and could not anticipate any claim entitled to 2000.
• If the claims lose the 2000 priority (AIA § 102(a)(1)/(a)(2) applies, effective filing date 2019): every Appendix B–R becomes prior art, and the analysis shifts to whether the combination of App. E/F (discovery), App. N/B (802.11 chipsets), App. G–J (print servers/output controllers), and App. D (short-range radio) renders claims 1, 8, and 15 obvious under § 103. Notably, App. F (2001) becomes available only on this branch — which is presumably why Roku led with the § 112 written-description/priority attack rather than with § 102.

The priority-chain applications (Ex. 1006 and Ex. 1010)

• U.S. Appl. No. 10/053,765 ("765 application") — filing date 2002‑01‑18; Google Patents lists the '903 patent as claiming priority from it. Used by Roku as Ex. 1006.
• U.S. Appl. No. 10/016,223 ("223 application") — priority date 2001‑11‑01; Google Patents lists the '903 patent as claiming priority from it. Used by Roku as Ex. 1010.
• U.S. Appl. No. 09/992,413 ("413 application") — cited as Patent Owner Ex. 2002; the Response repeatedly refers to "The '413 Application and '903 Patent."

§ 102 candidacy: these are same-family applications, so they are prior art only if the '903 claims are not entitled to their benefit. Even then, AIA § 102(b)(2)(A) ("obtained directly or indirectly from the inventor") and § 102(b)(2)(C) (common ownership) exceptions would likely disqualify them. They are best understood as priority/§ 112 evidence, not as anticipation art.

Not prior art — same-family documents sometimes mistaken for it

The Google Patents family/"Similar Documents" table for the '903 patent lists many Flexiworld patents sharing the 2000‑11‑20 and 2001‑01‑19 priority dates — including US 9,298,407 B2; US 9,836,259 B2; US 10,606,535 B2; US 9,841,935 B2; US 9,042,811 B2; US 8,989,064 B2; US 9,036,181 B2; US 9,069,510 B2; US 10,140,071 B2; US 10,841,798 B2; US 8,595,717 B2; US 11,829,776 B2; US 11,662,918 B2; US 9,116,723 B2. These are continuations/siblings in the same family and are not prior art against the '903 patent.

What I could not do, and how to close it

To produce the deliverable you asked for — each patent citation for US 11,029,903 with § 102 mapping — the front-page References Cited section is required, and I could not retrieve it. Recommended authoritative sources (I did not successfully query these):

• USPTO Patent Public Search (ppubs.uspto.gov) — full-text record with the "References Cited" listing;
• USPTO PatentCenter / file wrapper for 16/696,989 — includes the examiner's PTO‑892 and any IDS submissions;
• Google Patents "Patent Citations" and "Cited By" tables at https://patents.google.com/patent/[US11029903B2](/patent/US11029903B2)/en;
• The PGR2021‑00112 record on PTAB E2E (the withdrawn petition, Paper 1, would confirm the grounds definitively);
• The Flexiworld v. Roku, No. 6:21‑cv‑00680 (W.D. Tex.) docket for invalidity contentions, which would contain the actual § 102/§ 103 prior-art charting.

Bottom line

• US 11,029,903 B2 is confirmed as a Flexiworld continuation (Appl. 16/696,989, filed 2019‑11‑26, issued 2021‑06‑08, asserted priority 2000‑11‑01).
• No § 102 anticipation or § 103 obviousness ground was ever instituted or decided against this patent. The only post-grant proceeding, PGR2021‑00112, was instituted on claims 1–20 but pleaded § 112 written description / priority and § 101 theories, used Roku, Inc. as petitioner, and settled on 2022‑10‑31 with no final written decision.
• The closest prior-art-capable references I could positively identify are the eighteen technical publications in Appendices B–R of that petition. The strongest candidates against the distinguishing claim limitations are App. E (Richard III, IEEE Internet Computing, Sept./Oct. 2000) for the discovery/advertisement limitations in claims 1, 8, and 15; App. N (Intersil PRISM II, Feb. 1999) for the IEEE 802.11 chip/chipset limitations; and Apps. G–J (1997–1999 print-server literature) for the output-controller/output-device architecture.
• Confidence: high on the PGR facts (Board documents retrieved verbatim, with URLs above); low-to-nil on the patent's examiner-cited reference list, which I could not retrieve and have deliberately not reconstructed.

I'll build the § 103 analysis on the prior-art record already assembled, but first let me try to close two gaps flagged in the Prior Art section: the '903 claim set (especially the dependent claims) and the examiner-cited references.

Good — that surfaced new, citable material (claim-element text from the PGR petition's claim chart, dependent claims 3/14/18, the '903 assignment reel, and the full priority chain). Let me close the remaining gap: the '903 claim set and its front-page cited references.

Obviousness Analysis — U.S. Patent No. 11,029,903 B2 under 35 U.S.C. § 103

Building on the Prior Art, Litigation, and PTAB sections. I do not repeat the procedural history; I use it.

1. New record facts surfaced in this pass (and corrections to prior sections)

Before the merits, four new items materially change the § 103 picture — and one contradicts an earlier section.

(a) Structural claim data. The PGR petition's element chart (Ex. 1003) gives verbatim claim-element identifiers. Claim 1 has elements through [1r]; claim 8 is charted through [8p]; claim 15 through [15r]. These are very long independent claims (≥16–18 elements each). Element 1[q] ends with the limitation "the client device being a separate device from the output system and from the one or more servers," and 1[r] requires receipt of "audio or video digital content…" from the client device over the 802.11 WLAN.

(b) Dependent-claim content, at least in part. The petition's reply states that dependent claims 3, 14, and 18 each recite that the output system / output device is an output controller for a TV. Source: PTAB E2E, Roku reply. Everything else about claims 2, 4–7, 9–13, 16–17, 19–20 remains unretrieved — I will not characterize them.

(c) Full priority chain with provisional numbers (Sony complaint ¶ 74, RPX document mirror): 10/053,765 (filed 2002-01-18 → US 9,836,257); 09/992,413 (filed 2001-11-18 → US 9,965,233); 10/016,223 (filed 2001-11-01 → US 7,941,541); provisionals 60/262,764 (2001-01-19), 60/252,682 (2000-11-20), 60/245,101 (2000-11-01).

(d) ⚠️ Contradiction flagged — the '903 assignment Reel/Frame exists. The Assignment section concluded no reel/frame naming the '903 was found. Sony complaint ¶ 77 states: *"An assignment of the '903 Patent from inventors Chang and Liu to Flexiworld is recorded at the PTO at Reel/Frame 045907/0890."* That directly contradicts the earlier "absence finding." The ownership conclusion (inventors → Flexiworld, single hop) is unaffected, but the reel/frame citation the earlier section said was missing is available.

(e) ⚠️ Minor date conflict. Unified Patents lists US-11029903-B2's priority date as 2000-10-31; Google Patents shows prior art date 2000-11-01, and the complaint pleads provisional 60/245,101 filed 2000-11-01. I read identifiers literally and do not reconcile; note that a one-day shift matters for nothing here, because the controlling reference dates (1997–2000) are months or years away from either.

2. Framework

Governing law turns entirely on the priority fight (developed in the Prior Art section; I extend it). Two branches:

POSITA (Branch A): bachelor's in EE/CS plus ~2–3 years in networked consumer electronics or wireless LAN product development, familiar with IEEE 802.11, Bluetooth, print servers, and client-server media delivery. Roku's Appendices B–R were assembled precisely to define the "conventional" baseline at that level — App. B (Geier), App. D (Haartsen) and App. N (Intersil) are the technical anchors; Apps. G–K are the ordinary-skill anchors.

Claim construction: there is no PTAB or district-court construction of "output system," "job object," "digital document object," or "discovery operation" (established previously). For § 103 the practical consequence is that the scope of "output system" — controller-box-plus-TV vs. TV alone — is the swing issue, because element 1[q] says the client device is "a separate device from the output system."

3. Element mapping — the independent claims against the identified record

Using the elements I can source. "Portal" = reference available on Branch A; "B-only" = only on Branch B.

4. The combinations

Combination 1 — Claim 1

App. E (Richard III, Sept./Oct. 2000) + App. N (Intersil PRISM II, Feb. 1999) + Apps. G–J (print-server/output-controller literature, 1997–1999) + App. D (Haartsen, Bluetooth, Feb. 2000) + US 6,008,777 A / WO 1998/039766 A1.

Combination 2 — Claim 8

App. E + App. B (Geier 1999) + App. L (AirPort, July 1999) + Apps. G–J + App. D, with the OS-mediated application download/installation limitation met by App. O–R (Apple portable-evolution evidence) and the store/queue/spool limitation met squarely by Apps. G–J (queuing and spooling are the stated function of the external print server).

Combination 3 — Claim 15

Same spine, with App. E carrying the "broadcast availability and transmit at least one identification attribute" limitations — service advertisement inherently publishes a service identity, which is exactly what App. E describes (Jini/SLP/Bluetooth-SDP service attributes).

Combination 4 — Dependent claims 3, 14, 18

Apps. G–J + US 6,008,777 A. The print-server references already teach the interposed-controller architecture and the retrofitting of a legacy output appliance; US 6,008,777 A supplies the television end. Combining outputs a controller-box for a TV. (Note the irony: Flexiworld's POR argued these claims show lack of written description for the parents — the same record supports a § 103 reading if the priority theory succeeds.)

Combination 5 (Branch B only) — the fallback

If the claims lose the 2000/2001 chain, App. F (Sheldon, 2001) joins and the combination becomes Apps. G–J + E + F + N + D + B, with App. F supplying the explicit service-advertising/discovery taxonomy (Salutation, SLP, .NET, SSDP, Bluetooth, Jini, JetSend).

5. Motivation to combine

I can point to four independent, document-grounded rationales — this is the strongest part of the case, because the motivation comes largely from Flexiworld's own specification.

1. Known interchangeability of the 2.4 GHz wireless standards. The '903 specification itself states that Bluetooth, HomeRF and IEEE 802.11 are "a group of competing technologies operating in the 2.4 GHz unlicensed frequency band," that each "provide[s] solutions for wireless local area networks," and that "new local area wireless technologies may emerge or that the existing ones may converge." That is a KSR "known options / market forces" rationale in the patent. App. D and Apps. B/N/L/M are the two halves of it.
2. The retrofitted-controller rationale, also from the specification. The '903 states that "an output controller 104 with a wireless communication unit may be installed internally or connected externally to a legacy printer to provide it with wireless communication capability that was previously lacking." Apps. G–J teach precisely that interposed-box architecture (external/internal print server; expansion card; comparative PC Magazine review of Axis/D-Link/HP/Intel/Lexmark/Linksys boxes). Substituting "television" for "printer" as the appliance is a use of a known technique in an analogous consumer-electronics context.
3. User-driven demand. App. Q/R (Apple's Sept. 13, 2000 iBook "Presentations" material) and App. O/P document the market need for pushing content from a portable computing device to a larger display. The '903 specification recites that same need verbatim ("a user may want to output a complete web page or any document or file to a larger display screen nearby, even though the small screen of his/her mobile device cannot completely display…").
4. Discovery is a general-purpose infrastructure, not a device-specific trick. App. E and App. F both frame advertisement/discovery as a generic solution to "enabling universal device cooperation" — a POSITA would not treat applying it to an output appliance as a new invention.

Reasonable expectation of success: high on Branch B; on Branch A it depends on whether Apps. E and C antedate the invention date, but a POSITA reading App. E would have expected advertisement/discovery to work over the same 802.11 and Bluetooth links described in Apps. B, D, L and N. The claimed "processing into audio/video output data" was routine transcoding (the patent's own description treats it as ordinary RSP/convert/scale work).

6. Weak points, and how to shore them up

(i) The internet-content-service limitations are the soft spot. Appendices B–R are overwhelmingly local-networking references (WLAN, Bluetooth, print servers, discovery). Only App. C (Markoff) touches internet delivery, and thinly. Claim 1's elements (g)–(j) — a digital content service over the Internet, a list of available content, output data returned by the server — are not squarely met by any Appendix I could verify. You will need a second reference family: contemporaneous internet-to-television and streaming-media systems. I did not find these in the record, and I am not going to name specific patent numbers I have not verified. Flag as Tier 3 — verify provenance before use.

(ii) The "reverse direction" vulnerability cuts against you too. Roku's petition conceded that "[t]he '903 patent only describes output devices being discovered by, and receiving output data from client devices," and that "[n]othing in the '903 patent suggests that an information apparatus makes itself discoverable to." For § 112 that concession is a gift. For § 103 it is a liability: it invites the argument that no reference rendered the claimed direction obvious. App. E's direction-agnostic advertisement framework and Apps. G–J's "actively search for available clients or passively wait to be discovered" language are your best answers, and they are decent ones — but this is where the fight will actually be.

(iii) Antedating. App. E (Sept./Oct. 2000) and App. C (2000-10-30) are § 102(a)-only art on Branch A and can be sworn behind under Rule 131 (pre-AIA). App. C post-dates the earliest provisional by two days; App. E by roughly a month. Expect a priority/derivation fight over these two. App. F (2001) is entirely unavailable on Branch A — which is why the § 112/priority attack is the keystone and not a side show.

(iv) Don't cite Rivera as § 103 authority. The petition and the Board used Rivera (a Federal Circuit decision the papers describe as invalidating claims that conflated a receptacle/container with an inserted "pod") as a § 112 written-description analogue — the Board "agreed the '903 claims are like those invalidated." I could not verify its full citation and will not invent one. It is not a prior-art reference.

(v) Objective indicia. Nothing has been adjudicated. Flexiworld could argue industry coexistence of 802.11 and TV discovery (UPnP, DLNA) as long-felt need or copying — but any such showing needs a nexus to the claims, and the claims' distinguishing limitations were allegedly disclosed nowhere in the '903 specification (which undercuts nexus as much as it supports it). The confidential Roku license is not evidence of non-obviousness and is presumptively unavailable to you.

7. Bottom line

• On Branch B (claims lose the 2000/2001 chain): the claims are obvious. A strong, KSR-faithful combination — Apps. G–J + E + F + N + D + B, plus US 6,008,777 A / WO 1998/039766 A1 for the TV-wireless-link element — maps to elements 1(a)–(r), 8(a)–(p), and 15(a)–(r), with the motivation supplied substantially by the '903 specification's own admissions about 2.4 GHz convergence and legacy-device retrofitting. Notably, all of Appendices B–R are printed publications, so this ground is IPR-eligible (unlike the § 112 and § 101 theories, which are not).
• On Branch A (claims keep the 2000 priority): the case narrows but does not collapse. App. F drops out; App. E and App. C survive only as § 102(a) art subject to swearing-behind; § 102(b) support rests on App. N (Feb 1999), App. J (Jan. 1999), App. L (July 1999), App. B (1999) and the 1997–1999 print-server/PC literature — all comfortably before Nov. 1, 1999 — plus WO 1998/039766 A1 for the wireless-TV link. The internet-service limitations remain the weakest link on either branch and need Tier 3 art you will have to source.
• Two-front squeeze restated. Flexiworld needs the 2000/2001 chain for term and damages; the § 103 case (and the entire PGR) needs the opposite. The § 112(a) written-description/priority attack is therefore the keystone, not a backup — win it and the § 103 case opens wide; lose it and both the patent and its term expire in 2021.

Confidence: high on the claim-element structure, the reference identities in Appendices B–R, and the motivations drawn from the specification; moderate on the completeness of the element-by-element mapping for elements (g)–(j); low-to-nil on the examiner-cited reference list, which I still cannot retrieve — the front-page "References Cited" section did not surface in this pass either, so the analysis above rests on the PGR record and on candidates I have labeled as unverified rather than on the Office's own citations.
