CommWorks Solutions, LLC v. Renesas Electronics Corp.

I'll research this case across multiple sources to build a grounded overview.

Let me dig into the docket, the plaintiff's corporate structure, and any IPR history.

Let me verify the specific docket details and IPR history for the two asserted patents.

Case Overview: CommWorks Solutions, LLC v. Renesas Electronics Corp., No. 2:25-cv-01257 (E.D. Tex.)

The parties

CommWorks Solutions, LLC is a Georgia limited liability company with its stated principal place of business at 44 Milton Avenue, Suite 254, Alpharetta, GA 30009. Every public Rule 7.1 disclosure I found identifies Brainbox Innovations, LLC as its corporate parent; in at least one filing CommWorks additionally identified Invention Investment Fund I LLC, Invention Investment Fund II LLC, and Kheyfits Belenky LLP as interested parties (C.D. Cal. Notice of Interested Parties, CommWorks v. Linksys, 2:23-cv-09229; E.D. Tex. R. 7.1 disclosure, CommWorks v. EarthLink, 2:25-cv-00716). It is a classic non-practicing patent assertion entity: Stanford's NPE Litigation Database classifies its suits under "acquired patents," and IPWatchdog reported in 2021 that CommWorks is one of several Brainbox-controlled NPE subsidiaries funded by portfolios transferred out of Intellectual Ventures, which allegedly retained a security interest and a "backend" on licensing revenue — allegations raised in Altice USA's declaratory judgment actions against CommWorks and sister LLCs in D. Del. (IPWatchdog, Sept. 22, 2021; Stanford NPE DB). Its repeated counsel is Rozier Hardt McDonough PLLC (Carey M. Rozier, James F. McDonough III, Jonathan L. Hardt, Kenneth A. Matuszewski), with Kaleo Legal appearing in some matters.

Renesas Electronics Corp. is the Japanese parent of the Renesas group — a major global semiconductor supplier of microcontrollers, SoCs, and analog/power devices. Note that the complaint names the Japanese parent directly, not Renesas Electronics America, which matters for personal jurisdiction and venue arguments. I did not find confirmed defense counsel for this docket (Renesas entities have been targeted by other, unrelated NPE campaigns, including Koji IP, LLC v. Renesas Electronics America, N.D. Cal. 5:24-cv-03089, which was dismissed amid sanctions motion practice — a different patent campaign and plaintiff, mentioned only to avoid conflating the two).

The accused technology and the asserted patents

The complaint's theory, as summarized in the docket-derived complaint analysis for this case, targets Renesas chips, devices, and software supporting Wi-Fi Multimedia (WMM) and 802.11-2007+ functionality — i.e., standardized Wi-Fi QoS/priority-tagging behavior rather than a proprietary Renesas implementation (complaint analysis, 2:25-cv-01257). Combined with the WMM/802.11-2007+ framing in the case metadata, the WMM allegation appears to be the core of the case.

The two asserted patents are a reissue/original pair covering essentially the same disclosure:

• U.S. Patent No. 7,027,465, "Method for Contention Free Traffic Detection" (issued Apr. 11, 2006; application filed June 11, 2002) — a method for detecting priority data frames by extracting a bit pattern from a predetermined position (defined by an offset) in a frame and comparing it to a search pattern, so that low-cost access points can classify traffic without parsing all frame headers.
• U.S. Patent No. RE44,904, also "Method for Contention Free Traffic Detection" (reissue of U.S. 7,555,014, which issued June 30, 2009; reissued May 20, 2014) — the same contention-free/priority-traffic-detection concept as reissued, asserted against WMM/802.11e-style QoS functionality.

Caveat worth flagging: a complaint-analysis page indexed to this exact docket describes a broader multi-patent assertion (also listing the '285, '596, '807, '304, and '904 patents and accusing WPS and Wi-Fi Mesh products, including the CL8000, DA16200, and FC9000 families). That page appears to be generated from a CommWorks template used across its 2025 campaign and may not reflect this specific complaint. Because the case metadata lists only RE44,904 and 7,027,465, I treat those two as the patents-in-suit, but the asserted set should be confirmed against the PACER docket and the complaint's exhibits.

Procedural posture and venue

The case was filed in the Eastern District of Texas, Marshall Division (the "2:" prefix in 2:25-cv-01257 is the Marshall Division designation). Marshall is the district's flagship patent venue: its docket has historically been presided over by Chief Judge Rodney Gilstrap, with Magistrate Judge Roy S. Payne, and it is known for experienced patent judges, fast time-to-trial, and plaintiff-friendly procedures — which is why NPEs continue to file there despite the district's 2025 changes to patent case assignment practices. I could not confirm the specific judicial assignment or a filing date from the sources available to me, and the metadata lists the status as unknown; the case number sequence suggests a 2025 filing (CommWorks' other E.D. Tex. Marshall filings run from 2:25-cv-00024 in January 2025 through 2:25-cv-00716 in July 2025), but this is inference, not verified fact. CommWorks has used this venue strategically while routing several chipmaker suits to W.D. Tex. (e.g., CommWorks v. NXP, 7:25-cv-00395; CommWorks v. STMicroelectronics, 7:25-cv-00363), suggesting venue is being selected per-defendant to minimize TC Heartland/§ 1400(b) challenges.

Why the case is notable

1. Supply-chain NPE pattern. CommWorks is running a broad, standardized-technology campaign across the Wi-Fi value chain — broadband/CPE operators (Comcast, Charter/Spectrum, RCN, Cable One, Consolidated Communications, EarthLink), router/CPE vendors (DrayTek, AVM, Ubee, Extreme Networks, Linksys/Belkin, Grandstream), and, increasingly, the chip suppliers themselves (Texas Instruments, NXP, STMicroelectronics, Qualcomm, u-blox, Realtek, Renesas). Suing the chipmakers is the escalation play: it pressures the whole downstream stack at once, and the accused functionality is compliance with the Wi-Fi Alliance's WMM certification and the IEEE 802.11e/802.11-2007 QoS amendment — i.e., standard practice, which makes the patent claims a de facto tax on Wi-Fi silicon.
2. Rapid-resolution dynamics. Several parallel chipmaker suits terminated very quickly with with-prejudice dismissals — TI (2:25-cv-00439, stipulated dismissal with prejudice) and NXP (7:25-cv-00395, Rule 41(a)(1) voluntary dismissal with prejudice on Oct. 31, 2025), with STMicroelectronics dismissed shortly after (PatSnap docket analyses for TI and NXP). Those dismissals produced no validity or claim-construction rulings, so the patents remain presumptively valid — a signal that early licensing settlements, not adjudication, are the campaign's objective.
3. PTAB/IPR linkage. CommWorks has been a repeat PTAB target: Unified Patents filed IPR2021-01297 against CommWorks' U.S. 8,923,846, and the Board's Final Written Decision of Feb. 13, 2023 held all challenged claims (1–6, 9–13, 16–20) unpatentable; related claims of U.S. 7,769,374 were cancelled in reexamination (Docket Alarm, IPR2021-01297). That history makes a defensive IPR against the '465/RE'904 pair a plausible next step, though I found no confirmed IPR petition against either patent — that is a gap, not a negative finding.
4. Market context. The accused functionality (WMM QoS, priority frame tagging) sits inside virtually every modern Wi-Fi 6/6E/7 SoC. Renesas' Wi-Fi chip portfolio was assembled largely by acquisition (its CL8000-family Wi-Fi chips derive from Celeno, and its DA16200 Wi-Fi SoC from the Dialog Semiconductor acquisition), so a standardized-QoS royalty theory aimed at Renesas touches both legacy and newly acquired product lines — and, by extension, the MediaTek/Qualcomm/Broadcom/NXP competitors that have already been approached.

Sourcing note: Party identities, corporate parentage, patent titles/dates, the Unified Patents IPR outcome, and the TI/NXP dismissal language are well-sourced above. The specific filing date, judicial assignment, asserted claim set, and the exact accused Renesas product list for 2:25-cv-01257 are not verified — the leading public summary of this docket is an AI-generated complaint analysis that appears partly templated, so these details should be confirmed against PACER and the complaint itself before being relied on.

I'll research this case systematically, starting with the docket and case status.

Let me find the specific docket for the Renesas case.

Let me pull the specific docket and any filings for the Renesas case.

CommWorks Solutions, LLC v. Renesas Electronics Corp., No. 2:25-cv-01257 (E.D. Tex.)

Important caveat up front: This case is recent (the docket number sequence places the filing in roughly the November–December 2025 window) and it has not generated any published opinion, verdict, or news coverage that I could locate. Unlike CommWorks's earlier campaigns (CommScope/ARRIS, Vyve, TRENDnet, TI), there is no reported merits ruling, settlement order, or PTAB decision tied to this docket. I therefore separate what is verified from what is unverified/unknown, and I have not filled gaps with inference presented as fact.

1. Parties, patents, and campaign context

• Plaintiff: CommWorks Solutions, LLC, a Georgia LLC whose corporate parent is Brainbox Innovations, LLC (Rule 7.1 disclosure filed in companion case 2:25-cv-00716, E.D. Tex.). CommWorks is a high-volume wireless-networking patent enforcer asserting a legacy 3Com/U.S. Robotics–era portfolio.
• Defendant: Renesas Electronics Corp. (Japan), a semiconductor supplier; its U.S. affiliate Renesas Electronics America is often a co-defendant in suits against Renesas (e.g., Koji IP v. Renesas Electronics America, N.D. Cal.).
• Patents per case metadata: RE44,904 and 7,027,465. I note a substantive wrinkle worth tracking: RE44,904 and 7,027,465 are the same invention — RE44,904 ("Method for Contention Free Traffic Detection," reissued 2014-05-20, app. 13/171,882) is the reissue of 7,027,465 (issued 2006-04-11, app. 10/167,986). CommWorks nevertheless lists them as separate asserted patents in its complaints (see the TI complaint, 2:25-cv-00439, listing both at Exs. C–E/D). Any invalidity or exhaustion defense should test the overlap.
• Accused functionality: Renesas Wi-Fi Multimedia (WMM)/802.11-2007+ products; plus, on the complaint-analysis record, WPS and Wi-Fi Mesh product families (CL8000 family, DA16200, FC9000, et al.). Accused products are components/SoCs, not end-user devices — a fact that drives the royalty base and the indirect-infringement (inducement) theory.
• Companion suits in the same campaign (relevant because they create consolidation/transfer and estoppel dynamics):
  • CommWorks v. Texas Instruments, 2:25-cv-00439 (E.D. Tex., Judge Gilstrap) — same 7-patent family.
  • CommWorks v. STMicroelectronics, 7:25-cv-00363 (W.D. Tex., Judge Albright); CommWorks v. Marvell, 7:25-cv-00354 (W.D. Tex., Judge Albright).
  • CommWorks v. EarthLink, 2:25-cv-00716 (E.D. Tex., Judge Gilstrap, filed 2025-07-15).
  • Earlier wave: CommScope/ARRIS (2:23-cv-00510, dismissed with prejudice), Vyve Broadband (6:23-cv-00147, dismissed with prejudice), TRENDnet (2:23-cv-08048 C.D. Cal., dismissed with prejudice), Technicolor (1:22-cv-02827 N.D. Ga.).

2. Chronology of legal developments

A. Filing and initial pleadings

The complaint's substantive theories (from the docketed complaint analysis) follow CommWorks's template: (i) pre-emptive § 101 defense framing in the pleading itself ("claims are not directed to an abstract idea… inventive components that improve upon… preexisting network provisioning systems"), (ii) willfulness allegations, and (iii) indirect infringement via supplying SoCs plus "information and assistance to customers." The template also alleges a willful-blindness policy and relies on prior notice letters (in the parallel TI case, letters dated 2021-02-11 and 2021-03-05).

B. Pre-trial motions of substance

• Motion to dismiss (Rule 12(b)(6)/§ 101): none identified on this docket. Given CommWorks's pleading template expressly pre-empts § 101, a 12(b)(6) Alice motion would be an unusual early move here.
• Motion to transfer venue (§ 1404(a)): not confirmed. This is the single most likely early motion to watch. Renesas is a foreign defendant with no Texas HQ, and CommWorks itself filed parallel semiconductor-defendant suits in W.D. Tex. (Albright) against STMicroelectronics and Marvell — creating a plausible transfer argument and a JPML consolidation risk across the E.D. Tex. and W.D. Tex. cases. I found no order resolving a transfer motion.
• Motion to stay pending IPR: not confirmed / no record located (see § 4 below).
• Summary judgment: none identified.

C. Claim construction (Markman)

No Markman order or claim-construction hearing identified. Given the ~Nov–Dec 2025 filing date and the typical E.D. Tex. (Judge Gilstrap) schedule, a Markman hearing would ordinarily be expected in the late-2026 to early-2027 window — i.e., still ahead as of today (2026-09-21). No Markman outcome exists to report.

D. Discovery milestones

None identified. No scheduling order, ESI order, protective order, or discovery-dispute order surfaced in the sources searched. In this district, the strategic milestones to watch would be (i) the entry of the scheduling order, (ii) infringement contentions (P.R. 3-1/3-2), (iii) the close of fact discovery, and (iv) expert reports. The royalty-base fight (SoC-level vs. end-product-level apportionment) will be the central damages dispute.

E. Trial, verdict, post-trial motions

None. No trial setting, verdict, JMOL, new-trial motion, or fee motion exists. The case is far too young for any of these.

F. Final disposition / present posture

Present posture: active, pre-Markman, at an early stage. As of 2026-09-21 there is no judgment, settlement, or dismissal on the public record that I could locate. I cannot confirm whether an answer has even been filed. Treat the case as pending, with the caveat that a quiet, unwritten settlement is always possible (CommWorks's track record — CommScope, Vyve, TRENDnet — is a pattern of early stipulated dismissals with prejudice, each party bearing its own fees and costs, i.e., nuisance-value/portfolio licenses rather than litigated outcomes). If that pattern holds, a joint motion to dismiss under Rule 41(a)(1)(A)(ii) with prejudice, no fee-shifting, is the most probable near-term disposition.

---

3. Parallel PTAB proceedings on the asserted patents

I located one PTAB decision squarely on the CommWorks portfolio, but it is not on RE44,904 or the ’465 patent:

• Unified Patents, LLC v. CommWorks Solutions, LLC, IPR2021-01297, U.S. Patent No. 8,923,846 ("Recovery Techniques in Mobile Networks"): instituted 2022-02-14; Final Written Decision 2023-02-13 holding claims 1–6, 9–13, 16–20 unpatentable under § 318(a). The Board noted the related W.D. Tex. litigation (CommWorks v. Comcast Cable Communications, 6:21-cv-00366-ADA).

Related collateral developments visible in the IPR record (relevant to validity risk on the family):

• The petitioner argued that narrower claims of related U.S. Patent No. 7,769,374 were cancelled in an ex parte reexamination over similar art (including the "Rune" reference), and pressed collateral estoppel/issue preclusion against CommWorks on the broader ’846 claims. This shows the CommWorks portfolio has already absorbed adverse PTAB/reexam results.
• No IPR/PGR on RE44,904 or 7,027,465 is confirmed by my search. Given the ’465/’904 reissue pair's age (2006/2014) and the volume of litigation it has drawn, third-party challenges (Unified Patents or a defendant-triggered IPR) are plausible but I found no verified petition number or institution decision. Any § 315(b) one-year bar for Renesas is tied to service date (not yet confirmed), so the IPR-filing window may still be open — this is the key parallel-proceeding question to monitor.

---

4. Analytic read: what matters strategically

1. The ’465/RE44,904 reissue overlap is the sharpest legal issue. Asserting both the original patent and its reissue on the same conduct invites a double-recovery/surrendered-claim challenge and complicates the damages case. Track how CommWorks divides pre- and post-reissue damages periods.
2. Component-level accused products cut both ways. Renesas sells SoCs; a component-level royalty base is small per unit but the unit volumes are large, and the inducement theory requires proof of downstream end-user infringement — an area where E.D. Tex. juries have been receptive but the Federal Circuit has tightened standards.
3. Venue/transfer and JPML exposure. CommWorks's own split filing strategy (E.D. Tex. against TI; W.D. Tex. against STMicro and Marvell) gives Renesas ammunition for a § 1404(a) transfer to W.D. Tex. and creates a consolidation threat across the campaign.
4. CommWorks's settlement signature. Across at least four prior suits (CommScope/ARRIS, Vyve, TRENDnet, and the AVM case dismissed without prejudice on 2025-06-19), outcomes were procedural dismissals, not merits rulings — no claim construction, no invalidity judgment. The patents remain "live enforcement tools." A quiet, fee-neutral dismissal remains the most likely endgame absent a PTAB trigger.

---

5. Open items I could not verify (recommend PACER pulls)

• Exact complaint filing date and the complete asserted-patent list for 2:25-cv-01257 (metadata lists RE44,904 and ’465; the complaint analysis describes seven patents — reconcile these).
• Whether an answer/counterclaims has been filed, and any Renesas IPR petitions or § 101 motion.
• Whether a motion to transfer or stay is pending.
• Whether any IPR/PGR exists on RE44,904 or 7,027,465, and Renesas's § 315(b) deadline (service date).
• The scheduling order and Markman date.

Primary sources used: CommWorks v. Renesas complaint analysis (docket 2:25-cv-01257); E.D. Tex. complaint in CommWorks v. TI, 2:25-cv-00439 (RpxCorp/insight.rpxcorp.com/litigation_documents/16108218); CourtListener dockets for 2:25-cv-00716 (EarthLink), 7:25-cv-00363 (STMicroelectronics); Unified Patents v. CommWorks, IPR2021-01297 Final Written Decision (2023-02-13) and Petitioner's Reply (Docket Alarm); PatSnap litigation summaries for CommScope (2:23-cv-00510), Vyve (6:23-cv-00147), TRENDnet (2:23-cv-08048); Unified Patents litigation portal entry for 2:25-cv-00026 (AVM, dismissal 2025-06-19).

I'll research the docket and counsel for this case.

Let me dig into the specific docket for case 2:25-cv-01257.

Let me search PACER/CourtListener and the complaint document directly.

Bottom line first (verification status)

*I could not retrieve the PACER docket sheet or the complaint's signature block for CommWorks Solutions, LLC v. Renesas Electronics Corp., No. 2:25-cv-01257 (E.D. Tex.) in this session.* The case itself is real and the complaint has been analyzed publicly (see the AI-assisted complaint analysis at ai-lab-cl-prod.azurewebsites.net/case/dct/txed/2:25-cv-01257/doc/analysis/1, captioned "CommWorks Solutions LLC v. Renesas Electronics Corp"), but I was unable to open the filed PDF or docket entry showing the Rule 11 signature block or the appearances list.

Accordingly, the names below are not confirmed counsel of record in this case. They are the attorneys who have signed and appeared on behalf of CommWorks Solutions, LLC in its parallel 2023–2025 patent campaign, including its E.D. Tex. and W.D. Tex. 2025 complaints. That is strong circumstantial evidence of who is likely on the 2:25-cv-01257 pleadings, but it is an inference, not a docket citation. I have flagged each item's source.

---

Attorneys documented as representing CommWorks Solutions, LLC (2023–2025 campaign)

No in-house counsel identified. CommWorks Solutions, LLC is a Georgia licensing entity (44 Milton Ave., Suite 254, Alpharetta, GA 30009 per license agreements produced in Unified Patents v. CommWorks, IPR2021-01297). No in-house litigation counsel appears on any of its complaints.

Local counsel for the Renesas case: not verified. I found no local-counsel appearance for 2:25-cv-01257. Note that Rozier Hardt McDonough maintains a Texas (Austin) office and Hardt is Texas-barred, so the firm may be serving as its own Texas counsel.

Sourcing

• Signature blocks naming McDonough and Hardt as "Attorneys for Plaintiff COMMWORKS SOLUTIONS, LLC": CommWorks complaint dated March 4, 2025, W.D. Tex.

Caveats you should carry forward

1. The 2:25-cv-01257 signature block and any appearances are unverified. To close this out, pull the docket sheet (PACER or CourtListener RECAP docket for txed / 2:25-cv-01257) and check Dkt. 1 (complaint signature block) plus any separate "Notice of Attorney Appearance" or pro hac vice motions.
2. Do not treat the table above as appearances in the Renesas case. It is a counsel-of-record-pattern inference. If a different firm signed the Renesas complaint (CommWorks has also used other filings counsel in different districts), this list would be wrong.
3. Two data points worth noting about the case record. First, the public complaint analysis for No. 2:25-cv-01257 describes asserted counts covering the '904 and '465 patents plus the '807 patent, the '285/'596/'979 family, and U.S. Pat. No. 9,554,304 — broader than the two patents (RE44904, 7027465) in the case metadata you supplied. Second, the case docket number implies a filing in the late-2025/early-2026 window (compare 2:25-cv-01057, filed Oct. 22, 2025, and 2:25-cv-01144, filed Nov. 21, 2025), so any counsel list would be recent and possibly still being supplemented by pro hac vice motions.
4. Sealed filings: I have no indication that the complaint or the attorney list in this case is sealed, but I also cannot confirm they are not — I simply could not access the docket.

If you want, the next step is a direct docket pull for Dkt. 1 and the appearance entries; that is the only way to state counsel of record with the certainty this deliverable requires.

I'll research defense counsel for this docket across multiple sources.

Let me try more specific docket and firm-focused searches.

Let me pull the docket aggregator pages and search for the defendant's answer.

Bottom line

*I could not verify any counsel of record for the defendant in CommWorks Solutions, LLC v. Renesas Electronics Corp., No. 2:25-cv-01257 (E.D. Tex.).* I ran targeted searches against docket aggregators (Justia, Docket Alarm, CourtListener/RECAP, RPX Empower), the AI-indexed docket record for this case number, and open-web sources for defence-side filings. Nothing surfaced a name, firm, or appearance entry. Rather than populate the table you asked for with guesses, I'm reporting the negative result, the one adjacent (and non-transferable) name that did surface, and the specific steps that would close the gap. Consistent with the earlier sections in this deck, I am not naming anyone as counsel in this case.

What the searches produced on this docket

• The only public artifact indexed to 2:25-cv-01257 is the plaintiff-side complaint analysis at ai-lab-cl-prod.azurewebsites.net/case/dct/txed/2:25-cv-01257/doc/analysis/1. It is generated from the complaint and contains no defence-side information — no answer, no appearances, no signature blocks on the defence side. It does confirm the complaint is broader than the two patents in your metadata: it pleads counts on the '285, '596, '979, '807, RE44,904, '465, and '304 patents, accusing "Renesas Wi-Fi Multimedia Products," "Renesas WPS Products," and "Wi-Fi Mesh Products" (CL8000 family, DA16200, FC9000, among others). That corroborates the reconciliation flag raised in the earlier "Key legal developments" section.
• No docket sheet, appearance entry, Rule 12 motion, corporate disclosure, or pro hac vice motion for this case was retrievable. I found no sealed-document indicator, but I also cannot affirmatively confirm the appearance record is complete or unsealed — I simply could not reach it.
• No PTAB petition by Renesas against RE44,904 or '465 surfaced in the same sweep, so there is no IPR-mandatory-notices document (a common back-door source for identifying defence counsel) to work from here.

The one adjacent data point — flagged, not relied on

The only Renesas-side representation I could confirm is non-patent and non-transferable:

I also confirmed that Renesas is a repeat defendant in E.D. Tex. patent suits, including MR Licensing LLC v. Renesas Electronics Corp. et al, No. 2:25-cv-00441 (E.D. Tex.) (Renesas Electronics Corp., Denso Corp., and Denso International America named) and what appears to be 4:25-cv-00428 (E.D. Tex.) (Justia E.D. Tex. patent docket index). These are different plaintiffs on different patents, but the defence teams in those dockets are a plausible (not confirmed) place to look for overlap in Renesas's preferred E.D. Tex. local counsel — the same firm or local-counsel pairing often recurs across a defendant's Texas NPE docket.

Why the record is likely still thin (and why that's expected)

Three structural reasons, each of which is an inference flagged as such:

1. Foreign-parent service. The complaint names Renesas Electronics Corp. (Japan) directly, not Renesas Electronics America. Service on a Japanese entity under the Hague Service Convention routinely takes several months through the Central Authority, which pushes the Rule 12 response deadline — and therefore the first appearance and any pro hac vice motions — well past the filing date.
2. Filing timing. The 2:25-cv-01257 sequence sits alongside CommWorks's late-2025 E.D. Tex. filings (e.g., 2:25-cv-01057 and 2:25-cv-01144 in the Oct–Nov 2025 window) and just ahead of its 2:26-cv-00088 Realtek suit (filed 2026-02-02). A winter-2025/early-2026 filing with Hague service would plausibly still be pre-answer or barely past answer as of today, with a defence-side appearance list that is short and possibly incomplete.
3. No early dispositive motion. There is no Rule 12(b) ruling, transfer order, or stay order on the public record to name counsel from.

What I did not find (so you know the boundaries of this search)

• No lead counsel, of counsel, local counsel, or in-house counsel for Renesas Electronics Corp. in this case.
• No Renesas corporate disclosure statement or Rule 7.1 filing (which would also settle the parent/subsidiary relationship).
• No pro hac vice applications, which in E.D. Tex. are the usual vehicle for out-of-state IP boutiques and would disclose the full defence team.
• No Law360, Reuters Legal, or firm-press-release coverage linking any firm to this defense.

Recommended verification path (this is the only way to state counsel of record with confidence)

Pull these from PACER or the CourtListener RECAP docket for txed / 2:25-cv-01257:

1. Dkt. 1 (complaint) — confirms the asserted patents and the exact filing date; the civil cover sheet may name expected defence counsel.
2. Any "Notice of Attorney Appearance" entries and pro hac vice motions — these are the authoritative counsel list, and in E.D. Tex. they typically arrive in a single cluster alongside the answer. Watch for both an out-of-state IP firm and Texas local counsel (the district's local rules require a member of the bar of this court).
3. Defendant's answer, affirmative defenses, and counterclaims (invalidity/non-infringement/§ 101, plus any license/exhaustion defense keyed to the '465/RE44,904 reissue overlap) — the signature block is the fastest confirmation of lead counsel.
4. Rule 7.1/AO-120 corporate disclosure — settles the Renesas parent/subsidiary question that drives the § 1400(b) venue and TC Heartland analysis flagged earlier.
5. Cross-check the MR Licensing docket (2:25-cv-00441) for Renesas's E.D. Tex. defence team — useful corroboration, but confirm before relying on it.

If you can authorize a direct PACER pull or a Docket Alarm/CourtListener RECAP retrieval on those entries, I can populate the attorney-by-attorney table (name, role, firm, office, experience note) in one pass. Until then, the honest answer is: counsel for the defendant in this docket is unverified, and I have not invented any names to fill the gap.
