Maxell, Ltd. v. TCL Electronics Holdings Ltd. (f/k/a TCL Multimedia Technology Holdings Ltd.) et al.

I'll research this case across the ITC docket, parallel district court litigation, and PTAB proceedings.

I'll research this investigation across the ITC docket, PTAB, and press coverage. Let me start with several parallel searches.

Now let me dig into the ITC docket details (ALJ, target date, orders) and the parallel PTAB proceedings.

Maxell, Ltd. v. TCL — Inv. No. 337-TA-1420: Chronology and Outcome

Scope note up front. This was a Section 337 investigation at the U.S. International Trade Commission, not a district-court action. Several of the categories you asked about therefore have ITC-specific analogues rather than direct equivalents: the "complaint" is Maxell's 337 complaint (not a Rule 12 pleading), there is no "answer" with counterclaims but rather each respondent's Response to the Complaint and Notice of Investigation under 19 C.F.R. § 210.13; there is no motion-to-dismiss/transfer practice, no JMOL or new-trial practice, and no jury verdict. Instead the tribunal issues orders by the presiding ALJ, an initial determination (ID) on violation, and the Commission reviews (or declines to review) by notice. I flag below where I could not verify a fact from public sources.

---

1. Filing and institution (Aug.–Oct. 2024)

Strategic read: TCL's public framing (non-SEPs, narrow screen-mirroring/casting technology) presaged the two-track defense it then executed — non-infringement/invalidity at the ITC plus PTAB invalidity petitions — which is exactly what the Sept. 25 announcement promised.

2. Pre-trial motions of substance

There is no public record of a dispositive motion (no motion to dismiss or transfer exists in this forum; no summary-judgment mechanism in § 337 practice). The substantive pre-trial motions were termination motions, and they were the case's real turning points:

• Order No. 11 (2025-04-07) — termination of the investigation as to all asserted claims of the '502 patent, on Maxell's withdrawal of those allegations. Unreviewed by Commission Notice 2025-04-29. (89/90 FR notice; Chinese Trade Remedy compilation)
• 2025-04-23 — Maxell moves to terminate as to six respondents (T.C.L. Industries Holdings (H.K.) Ltd.; TTE Corporation; Shenzhen TCL New Technology Co.; TCL Optoelectronics Technology (Huizhou) Co.; TCL Overseas Marketing Ltd.; TCL Technology Group Corp.) based on withdrawal of the complaint allegations directed to them; unopposed.
• 2025-05-01 — OUII responds in support.
• Order No. 14 (2025-05-07) — ALJ grants termination as to those six "Terminated Respondents," finding Rule 210.21(a)(1) satisfied and no extraordinary circumstances. Unreviewed 2025-05-28. (USITC notice, 337_1420_notice05282025sgl.pdf)

Effect: by mid-May 2025 the case had shrunk from 12 respondents/4 patents to 6 "Active Respondents" (TCL Electronics Holdings; TCL Industries Holdings Co.; TTE Technology, Inc. d/b/a TCL North America; TCL King Electrical Appliances (Huizhou); Manufacturas Avanzadas S.A. de C.V.; TCL Smart Device (Vietnam)) and 3 asserted patents ('109, '860, '971). This is the classic ITC sequencing toward a global business resolution rather than a litigated judgment.

3. Claim construction (Markman equivalent)

• In § 337 practice the ALJ issues a claim construction order (often styled as an order on the parties' joint/competing claim-construction terms) rather than a Markman hearing ruling. I could not verify from public sources that a claim-construction order issued in 337-TA-1420 before the settlement; the Commission notices and Federal Register materials do not reference one.
• What the record does confirm is that discovery ran substantively into mid-2025, including a joint discovery stipulation (referenced in Order No. 19) and expert work: a public expert-disclosure filing in an unrelated N.D. Cal. matter lists a testifying expert "contracted by King & Spalding, counsel for the defendant, for ITC actions regarding internet-connected televisions: Maxell, Ltd. v. TCL Electronic Holdings Co., Ltd.; 337-TA-1420; (December 2024 to June 2025)." (expert disclosure, courtlistener) That confirms King & Spalding as TCL's ITC counsel and that expert discovery/merits work was underway through June 2025. Maxell's ITC counsel is not verified in the sources I reviewed.
• Related datapoint (not this docket): the '971 patent was the subject of a detailed claim-construction fight in Maxell's parallel ITC case against VIZIO, where VIZIO briefed nine disputed terms and argued that "processor" and "radio modem" are § 112 ¶ 6 means-plus-function terms. (VIZIO claim-construction brief excerpt, PTAB exhibit) That parallel construction dispute is the best available proxy for how the '971 terms would have been litigated in 1420, but no construction ruling in 1420 itself is confirmed.

4. Discovery milestones of strategic significance

• Protective order / joint discovery stipulation: Order No. 19 records that, apart from a

I'll search across multiple angles for press coverage of this investigation.

Found a promising lead — an ip fray report on the settlement. Let me pursue that and search for mainstream/trade coverage.

Let me find the actual ip fray article and any other settlement/outcome coverage.

Press coverage: thin, trade-press-dominated, and almost entirely filed from the docket rather than from the courtroom

Public reporting on Inv. No. 337-TA-1420 is sparse, and what exists clusters at two moments — the filing and, a year after the fact, the settlement's downstream consequences. I found no Reuters, Bloomberg Law, Bloomberg Industry Group, Ars Technica, The Verge, IPWatchdog, Patently-O, JD Supra, or EFF coverage of this investigation, and no mainstream or business-press coverage of the August/September 2025 settlement itself. The only filing-day news piece I located is Law360, which reported on 2024-08-23 under the headline "Maxell Urges Trade Commission To Bar TCL Smart TV Imports" that Maxell had asked the ITC "to permanently bar TCL from importing certain smart televisions that Maxell claims infringe several of its patents," emphasizing Maxell's allegation that "TCL continues to import allegedly infringing televisions despite being long aware of Maxell's patent portfolio" — i.e., a knowledge/willfulness frame rather than a technical or damages one. (The headline appears on Law360's Technology and International Trade news indexes; the underlying article is paywalled and I could not read its body, so I am limited to the published summary.) The remainder of the contemporaneous "coverage" is administrative transcription: China's MOFCOM trade-remedy service, 中国贸易救济信息网, published short procedural items on 2025-04-30 and 2025-05-29 tracking the Commission's decisions not to review Orders Nos. 11 and 14 (the '502 patent withdrawal and the six-respondent termination), and those items were syndicated to Sina Finance, 界面新闻 via 163.com, and provincial trade-adaptation portals. Notably, the settlement itself — the event that ended the case — generated no press release from either side that I could locate, only the Federal Register notice.

The one genuinely analytical piece is ip fray, which reported (newsletter copy dated 2026-09-01) that "Maxell Corporation of America has acquired a number of patents from TCL following the resolution of the two companies' patent dispute at the U.S. International Trade Commission and in the U.S. District Court, Eastern District of Texas," and that Maxell "has also recently launched fresh infringement litigation against Hisense Group," while remaining "locked in an ongoing dispute with Samsung." That framing — a settlement that converted into a patent transfer plus a license, feeding a rolling monetization campaign against other TV makers — is the most substantive press characterization of this case's outcome, and it treats 337-TA-1420 as one theater in a portfolio-wide licensing program rather than as a standalone dispute. IAM ran a mid-August 2026 piece headlined "Samsung faces new ITC probe as Maxell expands patent enforcement campaign," with a subhead noting that Maxell "has also sued Hisense in Texas over a licence renewal relating to the Chinese manufacturer's TVs"; the aggregated snippet I could retrieve does not confirm whether the article discusses the TCL resolution, so I treat it as campaign context rather than coverage of this investigation. A Chinese-language litigation blog (陆雨, WeChat) situates the TCL matter in Maxell's broader campaign against Apple, Samsung, Lenovo, TCL and Hisense over patents inherited from Hitachi's 2013 consumer-electronics transfer — the only source I found that supplies that lineage explicitly.

Where reporting departs from the record, the gaps matter. No outlet has reported any monetary figure — no settlement sum, no royalty rate, no license fee — and that is consistent with the docket: the ITC awards no damages, Maxell sought only a limited exclusion order and cease-and-desist orders, and Order No. 19 records that the parties filed the settlement agreement in confidential and redacted-public form under 19 C.F.R. § 210.21(b)(1), so the terms are not public. The ip fray patent-acquisition claim is the one assertion that goes materially beyond the ITC record: the Commission's notices say nothing about any assignment, and the acquirer it names is Maxell Corporation of America, a U.S. affiliate — not Maxell, Ltd., the complainant — so the claim would need confirmation against USPTO assignment records, which I could not check. ip fray also rolls the ITC and E.D. Tex. resolutions into a single "settlement," whereas the ITC record documents only a Rule 210.21(a)(2) settlement-based termination; the two proceedings were related but separately resolved. Finally, note the asymmetry in how the parties characterized the case publicly: TCL's counsel at King & Spalding describe it on the firm's own bio as "Case favorably settled" (see the Defendant representatives section above), while Maxell's side made no public statement I could find — so the only on-the-record "spin" from the defense camp is a law-firm résumé line, and Maxell's strategic rationale is available in the press only at second hand through ip fray's licensing-campaign reporting.

I'll research the docket and public filings for this investigation.

Key docket entry found. Let me dig into the specific appearance filings and the attorneys named.

Bottom line

Maxell, Ltd. was represented in Inv. No. 337-TA-1420 by Mayer Brown LLP, with Kfir B. Levy (Washington, DC) designated as lead counsel in the Notice of Appearance filed September 30, 2024 (EDIS Doc. No. 833690, "Notice of Appearance of Mayer Brown LLP on Behalf of Maxell, Ltd.; Designation of Kfir B. Levy as Lead Counsel"). No local counsel was retained — ITC practice does not require it, and Mayer Brown's Washington, DC office filled that function. Maxell did not appear through in-house counsel of record in the public filings I could locate.

Source caveat: EDIS document images are not freely retrievable through the search tools available to me. The document titles and numbers below come from the Patexia ITC docket index for 337-TA-1420, and the attorney roster comes from the protective-order agreement Maxell filed at Doc. No. 833795 and from Mayer Brown/PTAB filings in the parallel proceedings. I did not read the body of Doc. 833690 itself, so the caption list of attorneys on that notice is inferred, not directly quoted.

Counsel of record — Maxell, Ltd. (Complainant)

Procedural notes

• Appearance mechanism: counsel entered under 19 C.F.R. § 210.16 via Notice of Appearance rather than pro hac vice, so there is no PACER "counsel of record" list to check — the EDIS docket is the operative record.
• The related PTAB proceedings (TCL Electronics Holdings Ltd. v. Maxell, Ltd., e.g., IPR2025-00135) confirm Mayer Brown as Maxell's counsel in the companion validity fight, using the service address Maxell-TCL-Service@mayerbrown.com.
• The investigation terminated in its entirety by settlement (Order No. 19, Aug. 22, 2025; Commission determination not to review, vote Sept. 15, 2025, published 90 Fed. Reg. (Sept. 18, 2025)). No withdrawals of appearance or substitutions of counsel appear in the public docket index before termination, so the appearances above were in effect through termination.
• For contrast: respondents were represented by King & Spalding LLP, with Jeffrey M. Telep designated lead counsel (Doc. No. 834012, Oct. 3, 2024). MediaTek USA, a non-party, appeared through Maynard Nexsen (Doc. No. 837598).

What I could not verify

The full text of Doc. 833690 (the actual notice listing every attorney signing on for Maxell) and any sealed filings. If a precise, filing-by-filing attorney roster is needed, pull Doc. 833690 and Doc. 833795 directly from EDIS (https://edis.usitc.gov), which remains the authoritative source.

I'll research counsel of record for the TCL respondents in this investigation.

Found the key docket entry. Now let me verify the individual attorneys and their roles.

Bottom line

A single firm — King & Spalding LLP — entered appearance for all twelve TCL respondents, and it was the only defense firm of record before the case settled. The appearance was filed October 3, 2024 (EDIS Doc. 834012), styled "Notice of Appearance of King & Spaulding LLP [sic] on Behalf of [all 12 TCL entities]; Designation of Jeffrey M. Telep as Lead Counsel." No separate local counsel, no second defense firm, and no in-house attorneys appear of record on the public docket.

The best public evidence of the actual working team is the pair of "Agreement to Be Bound by the Protective Order" filings, which list every defense-side attorney who needed access to confidential business information: Doc. 834015 (Oct. 3, 2024) and Doc. 836603 (Nov. 6, 2024).

Notes, caveats, and flags

1. No local counsel or in-house counsel of record. The October 3, 2024 notice covered all twelve respondents in a single filing by K&S, and K&S handled the responses to the complaint and NOI (Docs. 836811/836812, Nov. 8, 2024). ITC practice does not require local counsel, so this is unsurprising. I found no appearance by TCL legal-department attorneys on the public docket, but in-house counsel would often appear only on APO/§ 207.7 confidentiality submissions rather than as counsel of record — so the absence is not proof they were uninvolved.

2. Watch a firm-name trap on Stephen Baskin. Several lawyer-directory aggregators (LawTally, LawyerDB) list Baskin at Mayer Brown in Washington, D.C., with the same bio text. That is stale data: Baskin moved from Kilpatrick Townsend to Mayer Brown in March 2013 (Law360/JDJournal, Mar. 14, 2013), appeared for Mayer Brown in C.D. Cal. in 2016–2018, and was at King & Spalding by late 2020 (Federal Circuit No. 19-1602 brief). He was K&S counsel here. This matters because Mayer Brown is Maxell's counsel in this very investigation — a confusion between the two firms would invert the parties. Do not rely on those aggregator pages.

3. Name spelling in the docket. Doc. 834012's caption reads "King & Spaulding LLP" (misspelled) — that is the filer's typo for King & Spalding LLP; the APO filings and firm bios use the correct spelling.

4. OUII is a party, not defense counsel. The Office of Unfair Import Investigations was named as a party (89 FR 79,307). The institution notice lists Pathenia M. Proctor (OUII) as the agency contact (89 FR 79307 notice); she is government staff, not respondent counsel. OUII filed a response in support of the joint termination motion on August 20, 2025 (90 FR 45053). Note also that the FR notice's spelling of the Mexican entity ("Manufacturers Avanzadas") differs from the case-metadata/NOI spelling ("Manufacturas Avanzadas") — a transcription variance, not a different party.

5. Verification gaps I could not close. (a) For Friel, Lafferty, Coots, Xu, Kennedy, and Valuyev, I found no independent firm-bio or court-filing corroboration of their K&S office or bar admissions — they are documented here solely as persons who executed ITC APO agreements on behalf of the TCL respondents, which is strong but not conclusive evidence of formal appearance status. (b) I could not retrieve the full EDIS document list, so I cannot rule out a later-filed supplemental notice of appearance or withdrawal (e.g., if an attorney left K&S). (c) I did not locate a public list of TCL's in-house signatories on the APO.

6. How to confirm definitively. Pull the PDFs of EDIS Docs. 834012 (Notice of Appearance / Designation of Lead Counsel), 834015 and 836603 (APO agreements), and 836811/836812 (Response to Complaint and NOI, whose signature block lists every attorney of record for the TCL respondents as of November 8, 2024). The signature block on the Response is the most reliable single confirmation of who was formally on the pleadings.

7. Timing context. All of the above representation ended on paper no earlier than the settlement termination: Maxell and the six Active Respondents filed the joint motion to terminate on August 11, 2025; ALJ Order No. 19 granted it; the Commission declined review and the notice issued September 15, 2025, published at 90 FR 45053 on September 18, 2025 (the metadata's termination date). No merits hearing occurred, so there is no ALJ ID assessing the defense team's litigation conduct.
