Fundamental Innovation Systems International LLC v. Coolpad Group Limited

I'll research this case across multiple sources to build an accurate overview.

Let me dig deeper into the docket history, the IPR linkage, and case outcome.

Let me verify the case outcome, the complaint's asserted patents, and the IPR result.

Case Overview: Fundamental Innovation Systems International LLC v. Coolpad Group Limited, No. 2:20-cv-00117 (E.D. Tex.)

Parties. The plaintiff, Fundamental Innovation Systems International LLC ("FISI"), is a non-practicing patent-holding entity (an NPE/PAE). Public Chinese legal-press coverage describes FISI as a Delaware LLC (formed October 2015, registered to do business in Texas in November 2016), headquartered in Flower Mound, Texas, under a parent, Fundamental Innovation Systems International Holdings LLC, and states that it acquired the asserted portfolio from BlackBerry (formerly Research In Motion ("RIM")) (thepaper.cn). The complaint confirms the patents "resulted from a large scale research and development program at Research In Motion Limited," and that FISI "is responsible for protecting and licensing" those innovations (Complaint, E.D. Tex. 2:20-cv-00117). The defendants are Coolpad Group Limited, its U.S. affiliate Coolpad Technologies, Inc., and Yulong Computer Telecommunication Scientific (Shenzhen) Co. Ltd. — i.e., the Coolpad smartphone group, a Chinese handset maker whose U.S. market presence was built partly on carrier-branded budget phones (e.g., the "Legacy" and "Revvlry" lines sold through U.S. carriers).

Accused technology. FISI alleges Coolpad infringes by making, using, selling, offering for sale, and importing mobile devices and their matching USB charging adapters. The complaint identifies dozens of accused handsets — including the Coolpad Legacy, Legacy S, Legacy Go, Snap, Revvlry, Revvlry Plus, NX1, Defiant, Conjr, Catalyst, Max, Note 3, Shine, Porto, Modena, Torino, Surf, and others — plus specific adapters (model CHA1165, a Shenzhen RuiDe Electronic Q3W18-1U-A unit, and the Coolpad RD0501000-USB-A-18MG) (Complaint ¶ 27). The technical theory is USB charging: the accused devices allegedly detect a non-standard "identification signal" (an "abnormal USB data condition," e.g., voltages driven onto the D+ and D− lines, distinct from ordinary USB enumeration) that lets the phone draw current beyond the standard USB specification limit — the mechanism underlying fast/rapid charging over a USB connector. FISI frames the underlying BlackBerry inventions as "a fundamental break from previous techniques for mobile device charging."

Patents in suit. The case metadata identifies U.S. Patent No. 7,834,586 ("Multifunctional Charger System and Method," issued Nov. 16, 2010, naming Daniel M. Fischer et al., application 12/714,204) as the patent at issue. Technically, the '586 is a charger/charging-system patent in the Fischer USB-charging family: it claims a charging system that detects and negotiates with a connected device via the USB interface so the device can be powered/charged — essentially the "smart charger" side of the D+/D− signaling scheme FISI asserts. Note that the complaint as filed expressly asserted more than just the '586, invoking a family of related BlackBerry USB-charging patents (the complaint references the '766, '127, '111, '550 and '936 patents as "Patents-in-Suit," and contemporaneous coverage stated Coolpad was sued on roughly five U.S. patents). The '586 is the member flagged in the case metadata, but the '586's IPR record and the parallel PTAB proceedings confirm the family was litigated together.

Procedural posture. Filed April 23, 2020 in the Marshall Division of the Eastern District of Texas before Judge Rodney Gilstrap — one of the most active patent venues in the country. FISI's own venue pitch emphasized the court's "substantial knowledge" of the portfolio from prior cases, noting earlier claim-construction orders in its 2016 LG and Huawei suits and its 2017 Samsung suit; venue against Coolpad Technologies was premised on a "regular and established place of business in this district, including the place of business of its CEO," and against the foreign Coolpad/Yulong defendants under 28 U.S.C. § 1391 (Complaint ¶¶ 16–23). The docket shows a docket control order entered October 12, 2020, setting a Markman hearing for April 20, 2021, a pretrial conference for August 30, 2021, and jury selection for October 4, 2021 (docket snippet). FISI's counsel included James Mark Mann and Gregory Blake Thompson; Coolpad was represented by Jeffrey Lance Johnson and Yufeng Ma among others. Court-tracking aggregators now list the docket as Closed (ExParte case page) — consistent with a settlement/voluntary dismissal, though I could not independently verify the specific terminating entry, so the precise disposition should be treated as unconfirmed.

IPR linkage and why the case is notable. Coolpad and related defendants fired back at the PTAB in February 2021, filing inter partes reviews against the asserted family; IPR2021-00599 (TCT Mobile (US), Inc. et al. v. FISI) challenged the '586, was instituted Aug. 27, 2021, and reached a Final Written Decision on Aug. 23, 2022 before APJs Arthur M. Peslak (writing), Jon B. Tornquist, and Bryan F. Moore, on challenged claims 1, 2, 8 and 9 (GreyB IPVerse; Patexia summary). Sources I could reach do not confirm the substantive holding/outcome, and the case metadata itself flags the IPR outcome as "not confirmed," so I won't characterize it. The '586 had previously been challenged in IPR2018-00485 (Huawei Device et al.), where institution was denied (Sept. 4, 2018). The case is notable as a data point in FISI's systematic BlackBerry-portfolio monetization campaign: FISI filed five suits on a single day (April 23, 2020) — against Aukey, OnePlus and Coolpad in E.D. Tex., and Lenovo/TCL/Belkin in D. Del. — after earlier 2016–2017 suits against LG, Huawei, Samsung and ZTE that ended in licenses (the complaint notes "over thirty companies" have taken licenses, including competitors of the defendants), and a 2019 fight with Apple in which Apple filed first for declaratory judgment. It illustrates the classic NPE playbook (assert a commercially important standards-adjacent charging portfolio against foreign handset makers in plaintiff-friendly Texas, paired with parallel IPRs), against the market backdrop of ubiquitous USB fast-charging technology.

Sourcing caveats: Party structure, accused products, patents, venue theory and IPR dates are grounded in the complaint PDF, PTAB filings and docket aggregators cited above. The precise termination event for the district court case and the substantive outcome of IPR2021-00599 are not confirmed by the sources available to me and should be verified against PACER and the PTAB Final Written Decision document itself.

I'll research this case systematically, starting with the docket and parallel PTAB proceedings.

Let me dig into the docket and the parallel IPRs more specifically.

Let me look at the docket details and identify Coolpad's own IPR filings.

Fundamental Innovation Systems Int'l LLC v. Coolpad Group Limited — 2:20-cv-00117 (E.D. Tex.)

Sourcing caveat up front: This docket has very thin public reporting. The complaint and the parallel PTAB record are available; the district-court docket itself (PACER/RPX/Ex Parte aggregators) shows only high-level status. I could not retrieve a docket sheet with individual ECF entries, so where I say a motion or order is "not confirmed," that means I found no public evidence of it — not that it didn't happen. I have not invented any attorneys, dates, or rulings.

1. The parties and the patents

Plaintiff: Fundamental Innovation Systems International LLC ("FISI"), a non-practicing entity organized in Delaware in Oct. 2015, with a stated principal place of business in Flower Mound, Texas. Parent: Fundamental Innovation Systems International Holdings LLC. FISI's portfolio consists of USB-charging patents developed at Research In Motion / BlackBerry. FISI states 30+ licensees, including Samsung, LG, Huawei and ZTE.

Defendants: Coolpad Group Limited (Cayman/Coolpad group parent), Coolpad Technologies, Inc. (U.S.), and Yulong Computer Telecommunication Scientific (Shenzhen) Co. Ltd.

Asserted patent per case metadata: U.S. Patent No. 7,834,586 ("Multifunctional Charger System and Method"), issued 2010-11-16 from an application filed 2010-02-26, claiming priority to provisional 60/330,486 (filed 2001-10-23). Inventors: Daniel M. Fischer, Dan G. Radut, Michael F. Habicher, Quang A. Luong, Jonathan T. Malton.

⚠️ Important discrepancy to flag: the operative complaint actually asserted five patents, not one — the '586, plus U.S. Pat. Nos. 7,239,111 ('111), 8,624,550 ('550), 8,232,766 ('766), and 7,986,127 ('127). The '586 is the one the metadata and the IPR record center on, and it is the patent whose separate PTAB challenge is documented.

2. Chronology

Pre-history (relevant context, 2016–2018)

FISI had already litigated this portfolio in E.D. Tex.:

• 2016-12: FISI v. LG Electronics, No. 2:16-cv-01425 (E.D. Tex.).
• 2016-12: FISI v. Huawei, No. 2:16-cv-01424 (E.D. Tex.).
• 2017-02: FISI v. Samsung, No. 2:17-cv-00145 (E.D. Tex.).
• 2018-01-31: E.D. Tex. claim-construction order in the Samsung case construing terms in the '111, '550, '586, '766 and '936 patents.
• 2018-04-02: E.D. Tex. claim-construction order in the LG and Huawei cases construing terms in the '111, '550, '586 and '766 patents.

These earlier constructions are why the Coolpad complaint argued that this district already had "substantial knowledge regarding the asserted patents" and that "principles of judicial economy further support venue in this District."

Filing & initial pleadings

• 2020-04-23 — FISI files Complaint in E.D. Tex. (Marshall Division), Case No. 2:20-cv-00117, against Coolpad Group Limited, Coolpad Technologies, Inc., and Yulong Computer Telecommunication Scientific (Shenzhen) Co. Ltd. Five counts: infringement of the '111, '550, '586, '766 and '127 patents. The complaint pleads direct infringement plus §271(b) inducement and §271(c) contributory infringement, willfulness (alleged actual knowledge "since no later than June 1, 2017"), compliance with §287, and requests treble damages and fees under §§284–285. Jury trial demanded.

  • Accused products: Coolpad Legacy, Legacy S, Legacy Go, Snap, Revvlry, Revvlry Plus, NX1, Defiant, Conjr, Modena 2, Torino, Note 3 Plus, Catalyst, Max, Torino S, Porto S, Note 3 Lite, Roar, Note 3, Shine, Porto, Modena, Surf; and charging adapters CHA1165, Shenzhen RuiDe Electronic Q3W18-1U-A, and Coolpad RD0501000-USB-A-18MG.
  • Jurisdiction/venue theories: For the two foreign defendants (Coolpad Group Limited and Yulong), personal jurisdiction under Fed. R. Civ. P. 4(k)(2); venue under 28 U.S.C. §1391 (non-resident aliens suable in any district). For Coolpad Technologies, venue under §1400(b), based on its "regular and established place of business in this district, including the place of business of its CEO."
  • Source: complaint PDF — https://cmosedu.com/jbaker/expert_witness/2020/Texas_ED_2_20_cv_00117.pdf

• 2020-04-23 — Same-day service of the complaint is recited in the 2021 IPR petitions ("Petitioner was served with the complaint in this action on April 23, 2020"), which started the §315(b) one-year clock.

• Wave filing: The Coolpad suit was one of five complaints FISI filed on 2020-04-23 — the others being D. Del. actions against Belkin (1:20-cv-00550), Lenovo (1:20-cv-00551), and TCT Mobile/TCL (1:20-cv-00552), and E.D. Tex. actions against OnePlus, Aukey and Jasco Products. (Chinese legal-press coverage: thepaper.cn, 2020-04-29.)

• Answer / counterclaims: Not confirmed. I found no public copy or reporting of Coolpad's answer, invalidity counterclaims, or any Rule 12 motion. Given that the case is now shown as closed, the responsive pleading may be a non-event in the public record.

Pre-trial motions of substance

• Motions to dismiss / transfer (e.g., §1406(a) improper venue, Rule 12(b)(2)): Not confirmed. No public order found. The complaint's front-loading of the Rule 4(k)(2) and §1391 arguments suggests venue/jurisdiction was anticipated as a battleground, but nothing in the public record confirms a ruling.
• Motion to stay pending IPR: Not confirmed for this docket.
• Summary judgment: Not confirmed for this docket.

Claim construction (Markman)

• No Markman order specific to 2:20-cv-00117 was found. The case appears to have terminated before reaching that stage in this docket.
• However, the term central to the '586 — "identification signal" — was construed in the district court litigation as "signal that identifies a power source type." That construction was carried into the PTAB: in IPR2021-00599 the Board stated it would "apply the District Court construction of 'identification signal' . . . as it is undisputed and appears consistent with the intrinsic evidence." (See Patent Owner Demonstrative Exhibits, IPR2021-00599.)

Discovery milestones

• Not confirmed. No public record of infringement contentions, invalidity contentions, expert reports, or deposition dates in this docket.

Trial, verdict, post-trial motions

• None. No trial, verdict, JMOL, new-trial, or fee motion appears in the public record; the case is listed as closed.

Final disposition / present posture

• Status: Closed per the Ex Parte docket aggregator (https://ai-lab.exparte.com/case/dct/txed/2:20-cv-00117/...), which records the case as filed 2020-04-23, Nature of Suit 830 (Patent), and Status: Closed. RPX's litigation page likewise exists but the disposition detail was not retrievable.
• The precise closing event (settlement + joint dismissal vs. voluntary dismissal vs. other) is UNCONFIRMED. I am not going to guess. The pattern across FISI's other campaigns (LG, Huawei, Samsung, ZTE) was resolution via patent license agreements followed by dismissal, and FISI's stated business model is licensing — so a negotiated dismissal is the most plausible reading, but that is inference, not a documented fact.
• No Federal Circuit appeal of anything in this docket was found.

3. Parallel PTAB proceedings on the '586 and their effect

(a) 2018 Huawei IPRs — first wave

• The '586 was the subject of IPR2018-00276, IPR2018-00487, and IPR2018-00495, as recited in the IPR2021-00599 Final Written Decision.
• IPR2018-00485 (Huawei Device Co. et al. v. FISI) — accorded filing date 2018-01-12; institution DENIED on 2018-09-04. (Plainsite docket: https://www.plainsite.org/dockets/42ks7efym/uspto-patent-trial-and-appeal-board/huawei-device-co-ltd-et-al-v-fundamental-innovation-systems-international-llc-et-al/)
• These 2018 challenges were filed while FISI's Huawei E.D. Tex. case was pending; the Huawei case settled after a license.

(b) 2021 TCT Mobile (TCL) IPR — the operative '586 challenge

• IPR2021-00599, TCT Mobile (US), Inc. et al. v. Fundamental Innovation Systems International LLC, filed 2021-02-26.

  • Petitioner / RPIs: TCT Mobile (US), Inc., TCT Mobile (US) Holdings, Inc., Huizhou TCL Mobile Communication Co. Ltd., TCL Communication, Inc.
  • Patent Owner RPIs: FISI and FISI Holdings.
  • Challenged claims: 1, 2, 8, 9 of the '586, ground: §103(a) over Morita in view of the knowledge of a skilled artisan.
  • Institution decision: 2021-08-27 (Patexia/ipverse).
  • Patent Owner Response: 2021-12-13. Petitioner Reply: 2022-03-04. Oral hearing: transcript dated 2022-07-15.
  • Final Written Decision: 2022-08-23 (Paper 34; Panel: Peslak, joined by Kokoski and Tornquist). Held: Petitioner proved by a preponderance that claims 1, 2, 8 and 9 of the '586 are unpatentable. Petitioner's Motion to Exclude (Ex. 2030) was dismissed as moot.
  • Sources: https://bannerwitcoff.com/wp-content/uploads/2022/08/IPR2021-00599.pdf ; https://ipverse.greyb.com/ptab-web/cases/case-details/IPR2021-00599 ; Banner Witcoff PTAB Highlights (Sept. 2022) noting the decision also addressed the proper scope of reply evidence.
  • Related-matter disclosure in the FWD expressly names the Coolpad E.D. Tex. case alongside the Lenovo and TCT Mobile D. Del. cases — this is the link the case metadata references.
  • Prosecution note: the Board reminded Patent Owner of the April 2019 Notice on amendments via reissue or reexamination during/after AIA trial. No reissue or reexam was confirmed.

• Companion 2021 petitions in the same campaign (each naming the 2020 FISI suits as related matters): IPR2021-00597 and IPR2021-00598 (institution decisions issued 2021-08-25 and 2021-08-30 respectively, per the IPR2021-00599 FWD's citations), IPR2021-00395, and IPR2021-00410. The '766 petition's mandatory-notice section lists the Coolpad E.D. Tex. action as the related litigation. I could not fully confirm petitioner identity for each of the companion numbers from the sources retrieved; the ones I could confirm (‑00599, ‑00410) are TCT Mobile/TCL.

(c) Coolpad's own IPR activity (adjacent, not against FISI)

Coolpad Technologies, Inc. was an active IPR petitioner in 2019–2020 — but against Bell Northern Research (BNR) patents, not FISI's. Examples: IPR2019-01185/IPR2019-01346 (with ZTE, on U.S. Pat. 6,941,156), IPR2019-01174/IPR2019-01345 (U.S. Pat. 7,990,842), and IPR2019-01320 (U.S. Pat. 7,319,889, which was jointly terminated on settlement after the BNR v. Coolpad S.D. Cal. case was dismissed on 2020-10-23). I found no Coolpad-filed IPR against the '586 or any other FISI patent.

(d) Effect on the litigation

• The 2022-08-23 FWD invalidating claims 1, 2, 8 and 9 of the '586 removed the principal asserted claim (claim 1) from the Coolpad case, and likewise from the parallel Lenovo and TCT Mobile cases. Any appeal would have been due under 35 U.S.C. §319 / Fed. Cir. R. 15 within 63 days of the FWD (roughly 2022-10-25); no appeal was confirmed, and the metadata's "outcome not confirmed" is consistent with an unappealed or unpublicized resolution.

4. Bottom line / what is missing

If you need the exact disposition (docket number of the dismissal order, settlement/license terms, or whether Coolpad ever appeared), the next step is a PACER pull of the full docket sheet for 2:20-cv-00117 or a Westlaw/Law360 docket report — those paywalled records are where the answer to the "Closed" entry will be documented, and I could not access them here.

I'll research plaintiff-side counsel of record for this case across docket aggregators, firm sites, and press coverage.

Now let me pin down the complaint's signature block and local counsel.

Good — the docket snippet confirms plaintiff-side appearances. Let me pull the full docket sheet and verify each attorney's firm.

Plaintiff-Side Counsel of Record — FISI v. Coolpad Group Ltd., No. 2:20-cv-00117 (E.D. Tex.)

Sourcing note up front: I could not open PACER or a full CourtListener docket sheet for this case within this session (the RPX Empower entry is paywalled and the ExParte aggregator page shows only a redacted "Attorney" field). The primary docket evidence I could reach is a reproduction of the case's docket-sheet attorney header that was filed as an exhibit in a parallel PTAB proceeding (PTAB petition document for the February 2021 Coolpad/TCL IPR filings, which embeds this district court's October 12, 2020 Docket Control Order and the accompanying docket header) (ptacts.uspto.gov artifact). That document names three plaintiff-side appearances. Everything else below is corroborated from parallel FISI matters and firm/bar records, and I flag what is confirmed versus inferred.

Confirmed appearances (from the docket header reproduced in the PTAB exhibit)

Not confirmed for this docket, but likely (flagging explicitly)

• Other Quinn Emanuel attorneys. In FISI's contemporaneous matters, the QE team included Brian P. Biddinger, Edward J. DeFranco, Kevin P.B. Johnson and (in the Apple case) Gyu Shik Jang (UniCourt, FISI v. Apple attorney list). The PTAB exhibit's docket header for this case did not reproduce them, so I cannot state they entered an appearance here — treat as unverified. Note that Biddinger/DeFranco are also the defendant-side contact points in the Delaware companion case (they appear in the Coolpad/TCL IPR courtesy-service lists for the D. Del. cases), so don't assume the same roster carried over.
• In-house counsel. FISI is an NPE with no identified in-house litigation attorney on this docket. The patent's prosecution/correspondence address of record is Botos Churchill IP Law LLP, 430 Mountain Ave., Suite 401, New Providence, NJ (IPR2021-00598 service certificate). That is prosecution counsel, not litigation counsel of record.
• Pro hac vice status and withdrawals. I could not verify admission dates or any later substitution/withdrawal (relevant because the case is now listed Closed on aggregators — consistent with settlement or voluntary dismissal, the specific terminating event still unconfirmed per the earlier section).

Related but not counsel in this district court case (avoid conflating)

FISI's PTAB/IPR representation was handled by different firms and should not be reported as district-court counsel of record here:

• Irell & Manella LLP (Los Angeles) — Hong Annita Zhong (Lead, Reg. No. 66,530) and Jason Sheasby — patent-owner counsel in IPR2021-00599 (the '586 IPR) (Patent Owner's Mandatory Notice).
• Covington & Burling LLP — David A. Garr (Lead, Reg. No. 74,932, Washington, DC) and Anupam Sharma (Redwood City, CA) — patent-owner counsel in IPR2018-00485 (Huawei's '586 challenge, institution denied) (Power of Attorney).

Summary

Plaintiff FISI's counsel of record in 2:20-cv-00117 were Joseph Milowic III of Quinn Emanuel (lead, New York) and J. Mark Mann and G. Blake Thompson of Mann | Tindel | Thompson (local counsel, Tyler, Texas). That three-name roster is the only set I can source to the docket itself; additional Quinn Emanuel personnel likely appeared but are unverified for this docket, and I found no in-house counsel of record. I'd recommend confirming against the PACER docket (entries for the complaint, any notice of appearance, and the termination order) before treating the roster as exhaustive.

Contradiction check: Nothing here conflicts with the case metadata or the earlier section — the earlier section's statement that plaintiff's counsel "included James Mark Mann and Gregory Blake Thompson" is confirmed and refined by adding Quinn Emanuel/Milowic as lead. One caution: the earlier section described the Mann/Thompson pair only by name; the PTAB docket header confirms they were counsel for FISI (plaintiff), not for Coolpad, in this case.

I'll research the defense-side counsel of record for this case across docket sources and firm materials.

Defense-side counsel of record — what I could and could not verify

Bottom line up front: The free docket aggregators for FISI v. Coolpad (2:20-cv-00117) — ExParte and RPX Empower — do not publish the attorney/appearance list (the ExParte page literally shows an empty "Attorney" column for both parties). I therefore could not pull the live PACER docket sheet, and the names below rest on secondary corroboration. I am flagging confidence per name rather than presenting a clean slate of "of record" attorneys.

1. Identified Coolpad-side counsel

2. The firm question for Jeffrey Lance Johnson — read this caveat carefully

I could not source a firm name for "Jeffrey Lance Johnson" in the 2020 timeframe, and I want to avoid conflating him with same-named lawyers:

• Search results surfaced a Houston-based E.D. Tex. patent litigator named Jeffrey Johnson at Orrick, Herrington & Sutcliffe (Ph.D. chemistry/engineering) who signed PTAB papers in the FISI IPR family, and a current Baker Botts profile for a Houston "Jeffrey Johnson" with the same E.D. Tex./handsets/telecom practice description (Baker Botts profile). The résumé overlap (Texas A&M interdisciplinary engineering Ph.D., East Texas chemistry B.S., E.D. Tex. patent bar) suggests these may be the same person as "Jeffrey Lance Johnson" who moved between firms, but I could not confirm the middle name or the firm-of-record for this case, so I am not asserting the Baker Botts or Orrick affiliation as fact. Unrelated same-named lawyers also exist (e.g., a WilmerHale technology-transactions "Jeff Johnson," a K&L Gates "Jeffrey C. Johnson") — do not attribute those to this case.

3. PTAB-side (same patent family) — likely the same defense team

In the parallel IPRs arising from the same FISI/UBS-charging campaign, the Orrick team signed as lead/back-up counsel in petitions that expressly list this Coolpad case as the co-pending litigation and state the petitioner "is the named Defendant in this pending case" served April 23, 2020:

• Jeffrey Johnson (USPTO Reg. No. 53,078) — Lead Counsel, Orrick, Herrington & Sutcliffe LLP, Houston, TX (609 Main St., 40th Fl.)
• Robert J. Benson — First Backup, Orrick, Irvine, CA
• Jeremy Jason Lang (Reg. No. 73,604) — Orrick, Menlo Park, CA

Sources: IPR2021-00598 ('766 patent) and IPR2021-00395 ('111 patent) petition papers (IPR2021-00598; IPR2021-00395); also PTAB petition/patent-owner correspondence. A damages/claim-construction expert's engagement list separately records Orrick (Houston/Irvine/Menlo Park) as the firm that retained him to prepare a claim-construction declaration in this very Coolpad case (expert engagement list), which is meaningful corroboration that Orrick was Coolpad's district-court team, not merely an IPR team.

Caveat: The Orrick petitioners used a docketing alias containing "TCL-FISI" and one IPR ("599) is attributed to TCT Mobile (US), Inc. et al. (the prior section's point). Orrick appears to have represented more than one FISI defendant in this campaign (Coolpad and/or TCL/TCT Mobile), so I would verify which Orrick petitions were filed for Coolpad before attributing every Orrick attorney to Coolpad. This is a potential nuance, not a contradiction of the metadata.

4. Coolpad counsel in other cases — context only, do NOT attribute to 2:20-cv-00117

• Perkins Coie: James Hurt appeared for "Coolpad Technologies, Incorporated and Yulong Computer" in Bell Northern Research, LLC v. Coolpad (S.D. Cal.) (deposition transcript).
• McDermott Will & Emery: Joseph Patrick Reid, John P. Schnurer, and Thomas Nathan Millikan filed notices of appearance for Coolpad Technologies / Yulong in the S.D. Cal. Coolpad litigation (2018) (PTAB exhibit reproducing that docket). Different case, different court, different patents.
• Pantech Corp. v. Coolpad Group Ltd., No. 5:21-cv-00065 (E.D. Tex., Texarkana) is a separate Coolpad defense; Coolpad's counsel there is not established by my sources.

5. What remains unverified / how to close the gaps

1. The live PACER docket for 2:20-cv-00117 — I could not retrieve it directly; the aggregator pages expose no attorney field. The definitive list is in the complaint caption's attorney block (Dkt. 1), any notices of appearance, the corporate-disclosure/financial-interest filings, and the terminating dismissal/settlement entry (case shows as Closed, consistent with the prior section's note that the exact termination event is unconfirmed).
2. Firm of record for Jeffrey Lance Johnson in this matter (2020–2021) — unresolved; candidates include Orrick (his firm in the parallel IPRs) but I have not verified it.
3. Yufeng Ma's existence/appearance and firm in this case — unresolved; do not repeat her name as fact without a docket check.
4. Whether Coolpad had separate local counsel (common in E.D. Tex.) — no such attorney surfaced in my searches.

Nothing indicates that any appearance in this case was sealed; the gap is simply that the free docket mirrors don't publish counsel fields and the case closed, so the appearance list must come from PACER or a paid docket service (Lex Machina/Docket Navigator/DPI) rather than the open web.

Cross-reference flag: This is consistent with, not contradictory to, the prior section's statement that "Coolpad was represented by Jeffrey Lance Johnson and Yufeng Ma among others." My research corroborates Johnson via the parallel Coolpad E.D. Tex. docket but could not corroborate Ma, and it adds the Orrick/PTAB team (Jeffrey Johnson, Robert J. Benson, Jeremy Jason Lang) plus the expert-retention corroboration as strong support that Orrick was the Coolpad defense firm. The prior section's identification of the Orrick-signed petitions as TCT Mobile proceedings is the one point where the Orrick-team attribution to Coolpad needs care.
