Flexiworld Technologies, Inc. v. Roku, Inc.

Case Overview: Flexiworld Technologies, Inc. v. Roku, Inc. (6:21-cv-00767-ADA)

Parties. Plaintiff Flexiworld Technologies, Inc. is a Washington corporation based in Vancouver, WA, founded and led by inventor William Ho Chang, and is best characterized as a patent assertion entity: it does not appear to sell products embodying the asserted technology and is tagged as a non-practicing entity in the Stanford NPE Litigation Database and by Unified Patents (which labels the patent owner "NPE (Small Company)"). Flexiworld describes itself as an early innovator in pervasive short-range wireless (Bluetooth/Wi-Fi) and mobile-device "output" technology, holding a large portfolio (129+ patents per Patsnap; ~59 USPTO grants 2015–2025) with priority dates around 2000–2001, and it has run a broad assertion campaign against Roku, Amazon, Samsung, Lexmark, Brother, Hisense, and others. Defendant Roku, Inc. is the Delaware-based streaming-platform company; at the time of filing its principal place of business was pled as 9606 N. Mopac Expressway, Suite 400, Austin, Texas (Complaint ¶¶3, 7), which anchored venue in the Western District of Texas.

Accused technology and patents. Flexiworld accused Roku's streaming ecosystem—Roku Devices (Express, Streaming Stick, Ultra), the Roku Mobile App, the Roku TV OS, and Roku TV Products (TCL, Hisense, Philips TVs running the OS)—of infringing four patents through wireless "casting"/screen-mirroring and device-setup functionality: (1) U.S. Patent No. 9,836,257 ("intelligent wireless display / wireless direct display" of digital content from a mobile apparatus to smart TVs, TV controllers, or audio output devices; asserted claim 27); (2) U.S. Patent No. 7,944,577 ("Output Controller for Mobile and Pervasive Digital Content Output," asserted claims 1 and 23, with the Roku device allegedly acting as the "output controller" that receives content/commands from the mobile app and passes them to the TV); (3) U.S. Patent No. 9,389,822 (mobile apparatus that receives video content from an internet service and wirelessly displays/plays it "over air" to TVs or projectors—i.e., casting—asserted claim 39 against the Roku Mobile App); and (4) U.S. Patent No. 10,846,031 (software application for wirelessly managing or setting up an output system/device; asserted claim 34). These claims stem from a portfolio whose provisional priority dates reach back to November 2000, giving Flexiworld very early priority for screen-casting and wireless-output functionality.

Procedural posture and venue. The case was filed July 27, 2021, in the W.D. Tex., Waco Division, and assigned to Judge Alan D. Albright (the "ADA" suffix)—at the time the most patent-docket-heavy district judge in the country, which made Waco a magnet for NPE filings. Venue was proper under 28 U.S.C. § 1400(b) because Roku maintained a permanent Austin office, so Roku could not contest venue on TC Heartland grounds. Early on, Roku filed a motion for partial dismissal for lack of standing (ECF 15, Nov. 5, 2021) and a motion to transfer (ECF 26, Oct. 20, 2021), and the case was stayed pending the standing ruling; Flexiworld's standing was a live issue because Roku argued certain Flexiworld patents had been assigned to Samsung in a 2011 agreement—a question Judge Albright resolved against Roku in the related case Flexiworld v. Roku, No. 6:20-cv-00819-ADA (Doc. 198, June 6, 2022, holding the '064 and '066 patents were not assigned to Samsung). In parallel, Roku filed PGR2021-00111 against the '031 patent (denied institution Mar. 14, 2022) and, on July 29, 2022, IPR2022-01267/01268/01269 against the '257, '822, and '577 patents. The parties then entered a confidential Patent License Agreement dated October 21, 2022, agreed to dismiss all claims with prejudice and terminate the IPRs, and the PTAB terminated the three Roku IPRs pre-institution on October 31, 2022; the district court dismissed the case with prejudice in 2022, and the settlement also wrapped up the other pending Flexiworld–Roku actions (6:20-cv-00819, 6:21-cv-00680, 6:21-cv-00882).

Why it matters. The case is a textbook example of the vintage-portfolio NPE playbook: early-2000s wireless "output" patents asserted years later against ubiquitous smartphone-to-TV casting features, in Judge Albright's Waco court, with a confidential license settlement before any merits ruling. It is notable for the multi-front IPR response—Roku's PGR and three IPRs plus Unified Patents' IPR2022-00775 against the '257 patent, the last of which the PTAB instituted (Nov. 8, 2022) and ultimately lost for the challenger, upholding claims 27–28 in a final written decision (Nov. 2023)—demonstrating the resilience of Flexiworld's early-priority claims. It also illustrates the standing-defense play (Samsung assignment allegations) that Roku and other Flexiworld targets deployed, and the settlement pattern that has characterized Flexiworld's campaign against streaming, printing, and display-device makers.

Note: I could not independently verify the precise docket entry number/date of the final dismissal order in 6:21-cv-00767 (the dismissal is confirmed through the parties' representations in the IPR termination papers), and the outcome of Roku's transfer motion is not in the sources located—the case settled before any ruling on it, so far as the record shows.

Key Legal Developments & Outcome — Flexiworld Technologies, Inc. v. Roku, Inc., No. 6:21-cv-00767-ADA (W.D. Tex., Waco Div., Judge Alan D. Albright)

Below is the chronological development of the case. Where the record is incomplete (dismissal order docket number, transfer-motion ruling, answer/counterclaims), I flag it explicitly rather than infer.

---

1. Filing & Initial Pleadings

2021-07-27 — Complaint filed (jury demanded). Flexiworld sued Roku for infringement of four patents: U.S. Patent Nos. 7,944,577 ('577, asserted claims 1 & 23), 9,389,822 ('822, claim 39), 9,836,257 ('257, claim 27), and 10,846,031 ('031, claim 34). The accused instrumentalities were the Roku Devices (Express, Streaming Stick, Ultra), the Roku Mobile App, the Roku TV OS, and Roku TV Products (TCL, Hisense, Philips sets running the OS). Venue was pled as proper under 28 U.S.C. § 1400(b) based on Roku's permanent Austin office at 9606 N. Mopac Expressway, Suite 400, Austin, TX 78759 (Compl. ¶¶3, 7). (Source: Case Readiness Status Report, filed 2021-10-25, ECF-available via PTAB/PTACTS; Ex Parte complaint analysis of 6:21-cv-00767; RPX Insight litigation document 14324357.)

Roku's response to the complaint — motion practice, not an answer. Roku received two extensions totaling 45 days. Per the parties' joint Case Readiness Status Report (2021-10-25), Roku "responded to the Complaint via the filing of Roku's Motion for Partial Dismissal Due to Lack of Standing" — i.e., the record I located does not show a conventional answer or counterclaims; Roku's initial defensive filing was the standing motion. I could not verify from available sources whether Roku ever filed a later answer or counterclaims before settlement, so I flag that as unconfirmed.

2021-10-20 — Motion to transfer (ECF 26). Roku moved to transfer venue. The parties' status report lists it as pending as of 2021-10-25. No ruling is documented in the sources located; the case settled before any transfer decision, so the motion was very likely mooted by the dismissal. I could not verify its disposition.

2021-11-05 — Motion for Partial Dismissal for Lack of Standing (ECF 15). Roku moved to dismiss the '577, '257, and '031 patents for lack of standing, invoking Flexiworld's 2011 assignment agreement with Samsung and arguing certain Flexiworld patents had been assigned away (the same theory pressed across the Flexiworld–Roku litigation). The parties agreed in the 2021-10-25 status report that "this case should be stayed pending the Court's ruling on the Standing Motion." (Source: Case Readiness Status Report, 2021-10-25.)

2021-10-25 — Case Readiness Status Report. Confirms the four asserted patents, fewer than 35 asserted claims anticipated, no Preliminary Infringement Contentions served yet, no request for a technical advisor, and no request for claim-construction assistance beyond the ordinary process. (Source: Case Readiness Status Report, 2021-10-25.)

---

2. Pre-Trial Motions of Substance

• Standing motion (ECF 15) + stay. The case was effectively frozen pending resolution of the standing question, which was litigated in parallel in the related Flexiworld v. Roku, No. 6:20-cv-00819-ADA. On 2022-06-06, Judge Albright issued Doc. 198 in 6:20-cv-00819, holding that the '064 and '066 patents were not assigned to Samsung under the 2011 agreement — applying Washington's "context rule" and rejecting Roku's broad reading of the assignment's "rights related thereto or arising thereunder" language. That ruling undercut the Samsung-assignment standing defense that Roku had deployed in 6:21-cv-00767 as well. (Sources: Order, Doc. 198, 6:20-cv-00819-ADA (W.D. Tex. 2022-06-06), via CourtListener/Justia/Casetext.) Note: the standing motion in this specific case concerned the '577/'257/'031 patents and I did not locate a separate order resolving ECF 15 on the merits before settlement.
• Motion to transfer (ECF 26, 2021-10-20). No ruling located; presumably mooted by settlement.
• No claim construction (Markman) occurred. The case was stayed on the standing motion and settled before claim-construction briefing, a Markman hearing, or a claim-construction order.
• No summary judgment motions or trial-ready motion practice are documented in the sources located.

---

3. Discovery Milestones

Discovery never meaningfully advanced: as of the 2021-10-25 status report, Flexiworld had not yet served Preliminary Infringement Contentions, and the parties agreed to stay the case pending the standing ruling. I found no significant discovery orders, privilege rulings, or expert-disclosure milestones for this docket in the available sources. (A Patexia document listing showing "Plaintiff's Motions in Limine" with a 2022-03-31 date appears to belong to the parallel Flexiworld v. Roku 6:20-cv-00819 matter — which did proceed toward trial — and should not be attributed to this case without verification.)

---

4. Parallel PTAB Proceedings (IPR/PGR) and Their Effect on the Litigation

• PGR2021-00111 (Roku v. Flexiworld; '031 patent). Filed 2021-08-24; Roku challenged the '031 patent in post-grant review. The PTAB denied institution on 2022-03-14 (35 U.S.C. § 324; panel: APJs Dougal, Moore, Ogden). This removed the PTAB pressure on the '031 patent and left that patent's validity to the district court. (Sources: Unified Patents PTAB portal for PGR2021-00111; DocketAlarm case page for PGR2021-00111.)
• IPR2022-01267 / 01268 / 01269 (Roku v. Flexiworld; '257, '822, '577 patents). Roku filed petitions on 2022-07-29 challenging the other three asserted patents. Flexiworld's preliminary responses were due 2022-12-08. These IPRs were terminated pre-institution on 2022-10-31 after the parties settled. (Source: Joint Motion to Terminate, IPR2022-01267 (filed 2022-10-27, DocketAlarm); PTAB termination decisions dated 2022-10-31.)
• IPR2022-00775 (Unified Patents v. Flexiworld; '257 patent). Unified Patents (a third party, not Roku) challenged the '257 patent. The PTAB granted institution on 2022-11-08 — after Roku's settlement and the district-court dismissal — and in a Final Written Decision in November 2023 (panel: APJs McMillin, Ogden, Dougal) upheld claims 27 and 28 of the '257 patent, rejecting Unified's § 103 challenge and dismissing Flexiworld's conditional motion to amend. This post-settlement decision is significant because it validated the very claim (claim 27) Flexiworld had asserted against Roku in this case, demonstrating the resilience of the early-priority (Nov. 2000) portfolio. (Sources: Institution Decision, IPR2022-00775 (2022-11-08, DocketAlarm); Patexia, "PTAB Upholds Flexiworld's Wireless Content Transfer Patent After Challenge by Unified Patents" (2023-11-03).)

Effect on the litigation: Roku's multi-front PTAB campaign (one PGR + three IPRs) plus the standing defense were its primary substantive challenges. The PGR denial (Mar. 2022) and the related-case standing ruling (June 6, 2022) eroded Roku's defensive posture; Roku then filed the three IPRs in late July 2022, but settlement short-circuited them before institution.

5. Settlement, Dismissal, and Final Disposition

• 2022-10-21 — Patent License Agreement executed. The parties entered into a confidential Patent License Agreement resolving all pending controversies between them concerning the asserted patents.
• 2022-10-25/27 — Joint termination papers. With PTAB authorization (email of 2022-10-25), the parties filed a Joint Motion to Terminate the three Roku IPRs on 2022-10-27, stating they were "concurrently filing joint motions to dismiss all claims in the Roku Litigation with prejudice." (Source: Joint Motion to Terminate, IPR2022-01267, filed 2022-10-27, DocketAlarm.)
• 2022-10-31 — PTAB terminated IPR2022-01267/01268/01269 pre-institution.
• 2022 (Q4) — District court dismissal with prejudice. The district court dismissed 6:21-cv-00767 with prejudice as part of the settlement. I could not independently verify the precise docket entry number and date of the final dismissal order in 6:21-cv-00767; the dismissal is confirmed through the parties' representations in the IPR termination papers (Joint Motion to Terminate, ¶¶ 5–6) and the Patexia account of the case ("resolved through a settlement in 2022").
• Global scope of the settlement. The October 2022 Agreement and dismissal also resolved the other pending Flexiworld–Roku actions: 6:20-cv-00819-ADA, 6:21-cv-00680-ADA, and 6:21-cv-00882-ADA (confirmed in the IPR joint motion to terminate, which lists those as related actions wrapped into the Agreement).

---

6. Trial, Verdict, and Post-Trial Motions

None. The case never reached trial, claim construction, summary judgment, verdict, or post-trial motion practice (JMOL, new trial, fees). The case is closed via settlement and dismissal with prejudice; no appeal was filed.

---

Summary of Outcome

Flexiworld's 2021 Waco filing against Roku's streaming/casting ecosystem ended in a confidential, global Patent License Agreement dated 2022-10-21, with dismissal with prejudice of this case and the three related Flexiworld–Roku actions, and termination of Roku's three pending IPRs (2022-10-31). Roku's PGR against the '031 patent had already been denied institution (2022-03-14), and the related-case standing ruling (2022-06-06) had rejected Roku's Samsung-assignment standing theory. After settlement, Unified Patents' independent IPR on the '257 patent was instituted (2022-11-08) but failed — the PTAB's November 2023 Final Written Decision upheld claims 27–28, the claim Flexiworld had asserted against Roku here. Net result: Flexiworld obtained a license covering Roku's entire accused ecosystem, and the asserted '257 claim later survived a PTAB validity challenge on the merits.

Caveats on sourcing: (1) The exact district-court dismissal order (ECF number/date) in 6:21-cv-00767 is not independently verified; (2) no ruling on Roku's transfer motion (ECF 26) or on ECF 15's standing motion specifically in this case was located — both appear to have been overtaken by the stay and settlement; (3) whether Roku ever filed a formal answer/counterclaims is unconfirmed from the sources reviewed (its initial response was the 2021-11-05 standing motion, per the status report).

I'll search for press coverage of this case from multiple angles.

Let me search more specifically for press and analyst coverage.

Let me pursue the Law360 coverage and other outlets.

Press and Analyst Coverage

Dedicated news coverage of Flexiworld v. Roku, No. 6:21-cv-00767-ADA, is thin. My searches across Reuters, Bloomberg Law, Law360, Ars Technica, The Verge, IPWatchdog, Patently-O, EFF Deeplinks and JD Supra returned no mainstream or legal-trade article written specifically about this docket's pleadings, motions, or settlement. Nearly everything that surfaces under the case caption is court-record aggregation rather than journalism — Docket Alarm and PTAB dockets (which is how the Oct. 27, 2022 Joint Motion to Terminate and the Oct. 31, 2022 termination decisions are publicly visible), CourtListener/Casetext and Justia for the related-case standing opinion (Doc. 198, 6:20-cv-00819), RPX Insight for the complaint text, and GreyB's ipVerse and Ex Parte analyses. These establish the record but are not press accounts, and I did not find any article reporting a settlement figure, damages demand, or executive statement about this case.

The one genuine piece of published analysis that discusses this case by name is a Patexia article dated Nov. 3, 2023, headlined "PTAB Upholds Flexiworld's Wireless Content Transfer Patent After Challenge by Unified Patents." Patexia framed the story around the Unified Patents IPR rather than the Roku suit itself, but expressly tied the two together: it identified the dispute as "Flexiworld Technologies, Inc. v. Roku, Inc., No. 6:21-cv-00767, filed in the Western District of Texas on July 27, 2021," stated that "Flexiworld accused Roku of infringing this patent, along with three others," and noted that "this case was resolved through a settlement in 2022." It reported the merits outcome — that the PTAB concluded Unified "failed to demonstrate the unpatentability of claims 27 and 28 of the '257 patent under § 103," with a panel of APJs Terrence W. McMillin, Christopher L. Ogden and Brent M. Dougal — and named Flexiworld's counsel team as Brent Bumgardner, Charles Ginnings and T. William Kennedy of Nelson Bumgardner Albritton P.C. That article adds detail (the expert declarations on each side, including an inventor declaration by William Ho Chang on conception and diligence) but offers no settlement terms, which is consistent with the parties' agreement being filed under seal as business confidential information in the terminated IPRs.

The closest trade-press item I located that touches the broader Flexiworld–Roku dispute is a Law360 case-tracking entry carrying an Oct. 24, 2022 article titled "Roku Gets PTAB To Trim Wireless Communications Patent," which Law360 summarized as the PTAB "largely invalidat[ing] claims in a wireless communications patent at the center of infringement litigation lodged against Roku and Amazon in the Western District of Texas." Two caveats, flagged explicitly: (1) The Law360 page it appears on tracks a Roku–Flexiworld IPR filed April 9, 2021 (Tech Center 2600), which corresponds to the IPR2021-00713/00714/00715 family directed at the '064/'066/'114 patents asserted in the related case Flexiworld v. Roku, No. 6:20-cv-00819 — not the '257/'822/'577/'031 patents at issue in 6:21-cv-00767. (2) That characterization ("largely invalidated") sits awkwardly beside the later outcome on this case's '257 patent, where the PTAB upheld claims 27–28 — a reminder not to conflate the two Flexiworld–Roku dockets. I could not retrieve the Law360 article body (paywalled), so I am reporting only the headline and the summary Law360 itself published, and I do not treat it as coverage of this case.

Bottom line on the press record: the settlement of 6:21-cv-00767 appears to have generated essentially no independent news reporting — unsurprising for a confidential, pre-institution NPE settlement — and what coverage exists is either (a) analytics-firm commentary centered on the Unified Patents IPR (Patexia), or (b) trade-press coverage of the sibling 2020 Flexiworld–Roku case and its IPRs (Law360). I found no Reuters, Bloomberg Law, Ars Technica, The Verge, IPWatchdog, Patently-O, EFF or JD Supra item addressing this docket, and no reported damages figures, settlement amounts, or market-impact analysis; any such numbers would need to come from the sealed Agreement, which the PTAB ordered kept separate.

I'll research the counsel of record for Flexiworld Technologies in this case.

I found initial information. The complaint was signed by Perkins Coie attorneys, but PTAB filings show Nelson Bumgardner Conroy later took over as lead counsel. Let me verify the docket appearances and firm details.

I have a good picture forming. Let me verify the transition from Perkins Coie to Nelson Bumgardner in the district court docket and confirm details on each attorney.

I've reached the search limit, but I have sufficient sourced information to answer. Here's what the record shows regarding plaintiff's counsel in Flexiworld Technologies, Inc. v. Roku, Inc., No. 6:21-cv-00767-ADA.

---

Counsel of Record — Plaintiff Flexiworld Technologies, Inc.

The case had two sets of counsel over its life: Perkins Coie LLP at filing (2021), and the Nelson Bumgardner firm (now Nelson Bumgardner Albritton P.C.) through the settlement and dismissal (2022). There is no evidence of in-house counsel appearing in the case; Flexiworld is a small NPE with no litigation department on the record.

Initial counsel of record (Complaint & Case Readiness Status Report, 2021)

These two attorneys signed the Complaint (filed July 27, 2021) and the October 25, 2021 Case Readiness Status Report as "Counsel for Plaintiff Flexiworld Technologies, Inc." (PTACTS/PTAB-filed copy of the status report; RPX Insight litigation document 14324357).

Substitute / later counsel (PTAB-linked, through settlement in 2022)

By May 2022, Flexiworld was represented by Nelson Bumgardner Conroy P.C. (renamed Nelson Bumgardner Albritton P.C. after merger with Judge Albright's former firm), which identified the 6:21-cv-00767 action in its PTAB mandatory notices and handled the joint motions to dismiss with prejudice and terminate the IPRs. Patexia's law-firm profile lists Nelson Bumgardner Conroy as plaintiff's firm on this exact case (case date July 27, 2021).

---

Key caveats (flagging what I could not verify)

1. Formal substitution in the district court docket. I could not access the PACER docket directly to confirm the exact docket entry (number/date) by which Nelson Bumgardner substituted for Perkins Coie as district-court counsel in 6:21-cv-00767. The transition is strongly evidenced by (a) the Patexia firm-profile listing of the case under Nelson Bumgardner Conroy, (b) Flexiworld's PTAB mandatory notices naming the district case and listing the Nelson Bumgardner team as lead/back-up counsel, and (c) Bumgardner signing the joint motion papers that effectuated the with-prejudice dismissal. If you need the precise substitution order, it requires a PACER/CM-ECF pull of the docket (ECF entries ~mid-2022, between the May 12, 2022 IPR notice and the October 2022 settlement filings).

2. Perkins Coie's dual role. Notably, Perkins Coie represented Roku in the parallel IPR2022-01268 petition even while (a different Perkins Coie team) had represented Flexiworld in the district court at filing — consistent with the parties rotating firms and the plaintiff's later switch to Nelson Bumgardner.

3. No in-house counsel on the record. William Ho Chang (founder/president) and Christina Ying Liu (shareholder) are named inventors, not attorneys; no Flexiworld in-house counsel appeared in the sources reviewed.

Primary sources: Complaint and Case Readiness Status Report signature blocks (PTACTS petition-document copies; RPX Insight doc 14324357); Flexiworld Patent Owner Mandatory Notices, IPR2022-00775 (May 12, 2022, DocketAlarm); Joint Motion to Terminate, IPR2022-01267 (Oct. 27, 2022, DocketAlarm, signed by Brent Bumgardner); Patexia law-firm profile for Nelson Bumgardner Conroy; Patexia, "PTAB Upholds Flexiworld's Wireless Content Transfer Patent…" (Nov. 3, 2023).

I'll research the counsel of record for Roku in this case through multiple searches.

The complaint signature block appears to list Roku's counsel but was truncated. Let me dig deeper into the docket and related cases.

The complaint signature block shows "COUNSEL FOR DEFENDANT ROKU, INC." was cut off. Let me find the actual attorney names from the docket and related joint filings.

I've reached the search limit. Based on the sources retrieved, here is what is verified versus what remains unconfirmed regarding Roku's counsel in Flexiworld v. Roku, 6:21-cv-00767-ADA.

Verified: Roku's counsel in the parallel PTAB proceedings (same dispute, same patents)

These attorneys appeared on behalf of Roku in the PTAB proceedings arising directly out of this litigation, and the case metadata confirms the IPR petitions were filed by Perkins Coie:

• Kyle Canavera — Perkins Coie LLP, San Diego (11452 El Camino Real, Suite 300). Verified by the IPR2021-00715 hearing transcript: "Kyle Canavera from Perkins Coie on behalf of Roku." Canavera is a Perkins Coie IP litigator who handles IPRs and district court patent defense for technology clients.
• Patrick McKeever — Perkins Coie LLP, San Diego. Verified in the same IPR2021-00715 transcript as Canavera's colleague on the Roku team ("Also with me is my colleague, Patrick McKeever from Perkins Coie").

Per the case overview (which I treat as authoritative), Roku's IPR2022-01267/01268/01269 petitions against the '257, '822, and '577 patents—the three patents asserted in this case—were likewise filed by Perkins Coie LLP, and those proceedings were terminated October 31, 2022, following the settlement.

Verified: opposing counsel (for context)

• Flexiworld's district court counsel: Matthew C. Bernstein (Perkins Coie, San Diego) and Martin E. Gilmore (Perkins Coie, Austin), per the signature block of the Case Readiness Status Report (Oct. 25, 2021) in this case, which lists "COUNSEL FOR PLAINTIFF FLEXIWORLD TECHNOLOGIES, INC." followed by a "COUNSEL FOR DEFENDANT ROKU, INC." block.
• Flexiworld's PTAB counsel: Brent Bumgardner (lead), Robert A. Delafield II, Charles Austin Ginnings, and Timothy E. Grochocinski of Nelson Bumgardner Conroy P.C., per the Patent Owner's Mandatory Notices in IPR2022-00775 (May 12, 2022).

Unverified / gap: Roku's district court counsel of record in 6:21-cv-00767

I must be explicit about the limitation: the names of Roku's counsel of record in the district court case itself could not be confirmed from the sources I retrieved. The Case Readiness Status Report (ECF, Oct. 25, 2021) and the complaint signature blocks contain a "COUNSEL FOR DEFENDANT ROKU, INC." section, but every retrieved snippet truncated immediately after that heading, before the attorney names. I did not locate Roku's notice of appearance, answer, or the standing/transfer motion signature pages in full text, and PACER access was not available to me. Accordingly, I am not attributing any specific firm or attorney as Roku's district court lead or local counsel, because doing so would risk fabrication.

Anomaly worth flagging

The record as retrieved shows Perkins Coie on both sides of the broader Flexiworld–Roku dispute: Perkins Coie (Bernstein/Gilmore) appears as Flexiworld's counsel in the W.D. Tex. district court filings, while Perkins Coie (Canavera/McKeever) appears as Roku's counsel in the PTAB IPRs. This is unusual and may reflect separate engagement teams, screens, or a shift in counsel over time (the district court filings are from 2021; the IPR appearances span 2021–2022). This requires verification against the actual notices of appearance and firm conflict disclosures before any firm-wide representation claim is made. It is also possible that Roku's district court defense was handled by a different firm entirely (Roku's other W.D. Tex. patent defense counsel have included Jackson Walker—the ESW trial win, April 2021—and Jenner & Block—the MV3 Federal Circuit affirmance, Nov. 2021), but I found no source connecting either firm to this specific docket.

Bottom line: Verified on this record are Roku's Perkins Coie IPR attorneys (Canavera, McKeever) in the parallel proceedings tied to this case. Roku's district court counsel of record in 6:21-cv-00767-ADA remains unidentified in my sources; the docket's defendant counsel block exists but its contents were not retrievable in full, and no attorney names should be treated as confirmed for the district court role without PACER/docket verification.
