Hitachi Maxell, Ltd. v. Huawei Device USA, Inc.

I'll research this case across the sources you named.

Let me dig into the docket history and the parallel PTAB proceedings.

Case Overview & Background

The parties. Plaintiff Hitachi Maxell, Ltd. — now Maxell, Ltd. — is a Japanese operating company, founded in 1961, with a long history in magnetic tape, optical disc, battery, and consumer electronics products; it still sells storage media, batteries, wireless charging products, and headphones. It is best characterized as an operating company with an aggressive outbound licensing program rather than a classic NPE/PAE (PACER-derived trackers such as Ex Parte classify the plaintiff as "Operating Company"). The patents asserted here arrived through a chain of internal Hitachi reorganizations: Hitachi, Ltd. assigned the portfolio to Hitachi Consumer Electronics in 2009, which assigned it to Hitachi Maxell in 2013, which later became Maxell, Ltd. (Maxell, Ltd. v. Huawei Device USA, Inc., No. 5:18-cv-00033 (E.D. Tex.), Compl. ¶ 4, https://www.docketalarm.com/cases/Texas_Eastern_District_Court/5--18-cv-00033/Maxell_Ltd._v._Huawei_Device_USA_Inc._et_al/docs/1.pdf). Defendants are Huawei Device USA, Inc. (the U.S. device subsidiary, then based in Plano, Texas) and Huawei Device Co., Ltd. (the Chinese handset maker), with [Huawei Technologies Co., Ltd.](/litigations/by-plaintiff/Huawei%20Technologies%20Co.%2C%20Ltd.) also appearing in the caption; Covington & Burling represented Huawei, and Mayer Brown together with Patton Tidwell & Culbertson represented Maxell (Law360, Feb. 21, 2019, https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1558234](/patent/1558234)/download-documents?artifactId=VTFr7hUhNM2d3s-CXoCgdDBP-_8UfXr5VPh7f3XB0uKx7Pe1jNy6EBg). Maxell's pre-suit narrative is a classic licensing-then-sue story: beginning June 10, 2013, it contacted Huawei CEO Ren Zhengfei and provided a list of infringed patents (including the '760 patent) dated June 3, 2013, and over roughly three years of meetings the parties failed to reach a license — the factual predicate for the willfulness allegations (Am. Compl., Count 7 ¶ 105, https://insight.rpxcorp.com/litigation_documents/[12599376](/patent/12599376)).

The accused technology and the patents. The accused instrumentalities are Huawei's Android smartphones — the complaint names the Mate 9 (with its RAW-plus-JPEG still-image capture, thumbnail generation, and display/reproduction of thumbnails and corresponding pictures) and identifies the P9 and Honor 8/8 Lite/8 Pro families as "reasonably similar" accused products (Am. Compl. ¶¶ 106–111, https://insight.rpxcorp.com/litigation_documents/12599376). The case as pleaded was a multi-patent assault — Maxell ultimately asserted fifteen patents across the Huawei and ZTE cases, eight of them against Huawei alone ('443, '139, '440, '292, '517, '901, '760, and '438) (Claim Construction Memorandum & Order, 297 F. Supp. 3d 668 (E.D. Tex. Jan. 31, 2018) (Dkt. 175), https://www.courtlistener.com/opinion/[7329083](/patent/7329083)/maxell-ltd-v-huawei-device-us-inc/), and the case metadata properly isolates U.S. Patent No. 6,856,760, "Recording Medium" (issued Feb. 15, 2005; inventors Masaru Takahashi and Junji Shiokawa; priority to JP 11-189868, filed July 5, 1999). In one line: the '760 patent claims a recording medium that stores moving pictures encoded by a "first encoding method," low-resolution "first pictures" (thumbnails) for those moving pictures, still pictures encoded by a different "second encoding method," low-resolution thumbnails for those still pictures, and still pictures re-encoded by the first (moving-picture) method from single-frame signals — i.e., dual-format still storage (e.g., an MPEG I-frame still plus a JPEG file) with thumbnails, so that both video-only players and PCs can reproduce the images (see IPR2018-00905 Petition at 1–3, https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1510559](/patent/1510559)/download-documents?artifactId=qhvEOM9wooxKpnY-XMXG0pCX-ONE6mZ6t8ElkR154-qph-hr0xpa6HM). Claims 1, 3–4, 6–7, 9–10, 12–13, and 15 were asserted against Huawei.

Procedural posture, venue, and why it matters. Maxell filed on November 18, 2016 in the Eastern District of Texas, Texarkana Division, before Judge Robert W. Schroeder III, Case No. 5:16-cv-00178-RWS, with a jury demand (Dkt. 1; Justia docket, https://dockets.justia.com/docket/texas/txedce/5:2016cv00178/[172640](/patent/172640)). The case was consolidated for pretrial purposes with the parallel ZTE action, No. 5:16-cv-00179-RWS. The court held a Markman hearing on November 29, 2017 (Dkt. 118, 138) and issued its claim construction ruling on January 31, 2018 (Dkt. 175), which was largely favorable to Maxell on the '760 patent's two key terms: the court rejected Huawei's proposed "moving picture encoding method" limitation and gave "first encoding method" its plain and ordinary meaning, likewise gave plain meaning to "still pictures encoded by a second encoding method…," and construed the claim 13 "displaying means" as means-plus-function with structure limited to a display medium such as an LCD panel 130 (297 F. Supp. 3d 668). Venue significance cuts two ways: filing in November 2016 captured EDTX before TC Heartland reshaped the venue landscape, and Huawei's Plano, Texas device operations supported the Texas forum; by contrast, Maxell's later '760-patent case against LG, filed in EDTX in December 2023, was transferred to the Northern District of California on July 1, 2024 under § 1404(a) (Joint Case Management Statement, No. 5:24-cv-04972-NW-SVK (N.D. Cal.), https://www.docketalarm.com/cases/PTAB/IPR2025-00393/LG_Electronics_Inc._v._Maxell_LTD/docs/04-11-2025-Patent_Owner/Exhibit-2002-Ex_2002.pdf).

Why the case is notable. Three reasons. First, outcome and portfolio validation through the co-pending ZTE case: the Huawei action did not reach trial — the parties told the court in mid-February 2019 that "all matters in controversy between the parties have been settled in principle," just before a scheduled hearing, with terms confidential (Law360, Feb. 21, 2019). But the same consolidated discovery and claim construction fed the ZTE trial, where a six-member jury in June 2018 found all seven remaining asserted patents infringed and willful, producing a $43.3 million verdict, followed by a confidential ZTE settlement in early February 2019 (Law360, Feb. 21, 2019). Second, IPR linkage and durability: Olympus (itself a Maxell target) petitioned for IPR of claims 1–15 of the '760 patent on May 18, 2018 in IPR2018-00905; the Board denied institution on November 19, 2018, finding no reasonable likelihood of prevailing (IPR2018-00905 status, https://ipverse.greyb.com/ptab-web/cases/case-details/IPR2018-00905; Maxell's later complaint recites that denial verbatim, No. 5:24-cv-04972 Compl. ¶ 20, https://ai-lab.exparte.com/documents/dct/[4519502](/patent/4519502)/5-24-cv-04972_cand_complaint_exparte.pdf). That survivorship is precisely why the '760 patent remained assertable against LG more than five years later — LG filed IPR2025-00518 on claims 1–9 in February 2025, arguing General Plastic and § 325(d) did not bar review because LG had no significant relationship with Olympus, and that dispute was reported settled in 2025 (https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1557332](/patent/1557332)/download-documents?artifactId=2I9gpd9gdJ-GU_nruiHW7nETu6HnSPvuxw5bDefh-51ZWQbdXsUxBbQ; MLex, Apr. 29, 2025, https://www.mlex.com/mlex/articles/[2332346](/patent/2332346)/maxell-lg-give-notice-of-settlement-in-california-patent-row). Third, market context and assertion pattern: this case is an early link in Maxell's decade-long campaign against Android OEMs and consumer-electronics vendors (Huawei, ZTE, Apple in 5:19-cv-00036-RWS, Motorola, ASUSTek, LG), monetizing a legacy Hitachi imaging/recording portfolio; the '760 patent's later life also exposes its § 101 vulnerability — LG moved for JMOL in October

I'll research this case across multiple sources.

Good foundation. Now let me dig into the docket, PTAB proceedings, and the settlement/dismissal.

Let me pull the docket and the key orders.

Maxell (f/k/a Hitachi Maxell), Ltd. v. Huawei Device USA, Inc. — 5:16-cv-00178-RWS (E.D. Tex., Texarkana Div.)

Bottom line: The '760 patent was one of eight Maxell patents asserted against Huawei in this case, but it was never tried. The case was settled in principle in February 2019 on confidential terms before any trial or summary-judgment ruling on the '760, so there is no verdict, claim-construction appeal, or JMOL/fee decision on this patent. The most significant substantive ruling in the case was the January 31, 2018 claim construction order, 297 F. Supp. 3d 668 (E.D. Tex. 2018).

1. Filing and initial pleadings

Answer / counterclaims. Huawei answered and asserted counterclaims (the docket includes an "Answer to Counterclaim" and "SUMMARY JUDGMENT"/"Partial Summary Judgment" entries; see Plainsite docket). Caveat: I could not retrieve the answer/counterclaim docket numbers or dates from a primary source, so I am flagging that item as not verified.

Venue posture. Unlike ZTE — which filed an opposed motion to dismiss/transfer to N.D. Tex. under 28 U.S.C. §§ 1404/1406 in the companion case and withdrew it on 2017-07-14 (post-TC Heartland) (ZTE docket) — Huawei did not seek transfer. That is unsurprising: Huawei Device USA was described as a Texas corporation headquartered in Plano, Texas, which also mooted any venue challenge. Maxell itself later noted in the follow-on suit that "[c]urrently there are no venue challenges pending" in No. 5:16-cv-00178 (5:18-cv-00033 complaint).

2. Pre-trial motions of substance

No motion to dismiss or motion to transfer was litigated to decision in the Huawei case. The heavy motions practice I could document falls into two buckets:

(a) Claim-construction briefing (the real substantive fight).

• 2017-09-01 — P.R. 4-3 Joint Claim Construction and Prehearing Statement (Dkt. 74).
• 2017-10-02 — Maxell's opening claim construction brief (Dkt. 95).
• 2017-10-23 — Huawei (and ZTE) responsive brief (Dkt. 100), which devoted a section (Part VIII.A) to the '760 patent's "first encoding method" limitation (claims 1, 3-4, 6-7, 9-10, 12-13, 15) (brief text).
• 2017-10-30 — Maxell reply (Dkt. 106).

(b) Discovery sanctions.

• March 2018 — Maxell moved to sanction Huawei for its "complete disregard" for court orders and its obligations under the rules of discovery, alleging Huawei's conduct "reached new heights." This is reported by Law360 (reproduced at PTAB E2E). The court's cross-docketing order in the ZTE case directed that motions at Dkt. Nos. 124, 184, 194 and 196–209 in No. 5:16-cv-178 be docketed in 179, indicating that Dkt. 124 was one of the pretrial motions being managed jointly. I could not confirm the exact docket number or outcome of the sanctions motion.

(c) Summary judgment / Daubert. The summary-judgment and Daubert activity visible on the dockets (partial SJ of no invalidity, SJ of non-infringement, four Daubert motions) appears almost entirely on the ZTE side of the consolidated pretrial proceedings — e.g., motions directed to the '317, '329, '443, '491, '695, '193, '493, and '729 patents, cross-filed as Dkt. Nos. 196–209 in 178 (ZTE docket detail). I found no summary-judgment ruling addressing the '760 patent; the case settled before the Huawei patents reached dispositive-motion rulings.

No stay pending IPR was granted (or, so far as I can find, sought) in No. 5:16-cv-178. I want to correct a common conflation: the motion to stay at Dkt. 239 citing PTAB statistics and Fresenius ([archived brief](https://www.archive.org/download/gov.uscourts.txed.188

I'll research plaintiff's counsel for this case across the docket and firm sources.

Good leads. Let me pull the full docket appearance list and confirm each attorney's client and role.

Let me verify the counsel block in the court's opinion and check the docket's representation list.

Plaintiff's counsel of record — Maxell, Ltd. (f/k/a Hitachi Maxell, Ltd.) v. Huawei, No. 5:16-cv-00178-RWS

Sourcing note up front. The best primary-derived list of plaintiff's counsel in this case is the counsel block of the court's own claim construction opinion, Maxell Ltd. v. Huawei Device U.S. Inc., 297 F. Supp. 3d 668 (E.D. Tex. Jan. 31, 2018) (Dkt. 175), which states: "Jamie B. Beaber, William Justin Barrow, Alan M. Grimaldi, Alison T. Gelsleichter, Baldine Brunel Paul, Bryan Christopher Nese, Clark S. Bakewell, James A. Fussell, III, Justin Park, Kfir B. Levy, Michael T. Lindinger, Saqib Javaid Siddiqui, Tiffany A. Miller, Tyler J. Earnest, Mayer Brown LLP, Washington, DC, Robert Gary Pluta, Amanda Streff Bonner, Mayer Brown LLP, Chicago, IL, Geoffrey Patton Culbertson, Patton Tidwell & Schroeder, LLP, Texarkana, TX, for Maxell Ltd." (casemine reproduction of the opinion). That block is corroborated in part by the Justia docket (listing Beaber, Culbertson, Fussell, Grimaldi, Levy, Miller, Paul, Siddiqui, and "Amanda Kay Streff" — i.e., Amanda Streff Bonner — under the plaintiff's "Represented By" heading) and by PTAB filings in which the same team was designated for Maxell as patent owner.

Bottom line: Maxell was represented by a two-firm team — Mayer Brown LLP (Washington, DC, led by Jamie B. Beaber, with the Chicago office's Robert G. Pluta handling PTAB/patent-side work) as national trial/appellate counsel, and Patton Tidwell & Schroeder, LLP of Texarkana as local counsel under E.D. Tex. Local Rule AT-2. I found no in-house Maxell attorney entering an appearance.

1. Lead trial counsel — Mayer Brown LLP, Washington, DC

2. Patent-side lead — Mayer Brown LLP, Chicago

I'll research Huawei's counsel of record across the docket, PTAB filings, and firm sources.

Good — I have an initial counsel list from the claim construction opinion. Let me verify against the docket and firm sources.

Now let me verify the lead-counsel designation, later appearances, and attorney backgrounds.

Counsel of Record for the Defendant(s) — Maxell (f/k/a Hitachi Maxell), Ltd. v. Huawei Device USA, Inc., No. 5:16-cv-00178-RWS

Bottom line. Huawei's defense was led by Covington & Burling LLP out of its Silicon Valley/Redwood Shores office, with Stanley Young designated attorney-in-charge. Jennifer Parker Ainsworth of Wilson, Robertson & Cornelius, P.C. (Tyler, Texas) served as local counsel, and KD Shull appeared as Huawei in-house counsel from Huawei Technologies USA Inc. (Plano, Texas). The full slate of Covington appearances in the published claim construction opinion is eight attorneys across Redwood Shores, Washington DC, New York, and San Francisco. No counsel appeared for the caption entity "Huawei Technologies Co., Ltd." on the docket report, consistent with the January 2017 dismissal of that party.
