Apple Inc. v. Parus Holdings, Inc.

Parties and dispute background. This matter is Apple Inc. v. Parus Holdings, Inc., IPR2022-00950, an inter partes review at the Patent Trial and Appeal Board (PTAB) filed May 5, 2022, in which Apple sought to invalidate U.S. Patent No. 6,721,705 (the "'705 patent," "Robust voice browser system and voice activated device controller"). Apple is a Cupertino-based operating company whose flagship voice assistant, Siri, was the accused technology. Parus Holdings, Inc. is a privately held, venture-backed, Chicago-based company (founded 1997) that describes itself as a pioneer in voice-enabled unified communications, but in this context operates as a patent monetizer: it acquired the '705 patent (and related voice-browser patents) from Webley Systems in 2004 and has asserted its voice-UI portfolio against Apple, Google, Samsung, LG, and Microsoft in a series of W.D. Tex. and N.D. Cal. suits (e.g., Nos. 6:19-cv-00432/433/438, 3:20-cv-05896). Per Parus's own September 17, 2021 press release, the district court suit alleged Apple's infringement was "willful" and sought treble damages, attorneys' fees, and a permanent injunction. The underlying infringement case — Parus Holdings Inc. v. Apple Inc., No. 6:21-cv-00968 (W.D. Tex., filed Sept. 17, 2021, before Judge Alan D. Albright) — asserted the '705 patent and U.S. Patent No. 8,185,402 ("'402 patent"), both titled "Robust voice browser system and voice activated device controller." Only the '705 patent was at issue in IPR2022-00950.

Accused technology and patents. The accused products were Siri-enabled Apple devices — the complaint listed essentially every Siri-capable product, including iPhone, iPad, Mac, Apple Watch, and HomePod — plus, per contemporaneous reports, Apple's "Applebot" web crawler. Parus alleged that Siri practices the claimed voice-browser/device-controller technology: the user speaks natural-language voice commands, the system queries networked databases and web content, ranks/presents results, and converts responses into audio output — the same functionality described in the '705/'402 patents, which claim a "robust voice browser system and voice activated device controller" that accesses and sorts web/online information via a maintained database and renders it on wired or wireless devices, with embodiments covering voice control of home devices (cameras, lighting, TVs). The '705 patent was filed in January 2001 by Webley Systems (app. 09/776,996), granted April 13, 2004, to inventors Alexander Kurganov and Valery Zhukoff, and acquired by Parus in 2004 — early-internet-era claims now aimed at modern smart assistants.

Procedural posture, venue, and significance. The PTAB denied institution of IPR2022-00950 on December 6, 2022 (Decision Denying Institution of Inter Partes Review under 35 U.S.C. § 314(a), docket entry No. 7), so the '705 claims survived without any invalidity finding; Google Patents' "settlement" status reflects the broader dispute's resolution. In parallel, Judge Albright granted Apple's motion to transfer the W.D. Tex. case to the Northern District of California (Apple's home district), where it was re-filed as No. 3:22-cv-07514 (Judge Vince Chhabria) and dismissed with prejudice on February 3, 2023, with each party bearing its own fees — a negotiated exit roughly 65 days after the N.D. Cal. filing, per PatSnap's case review (settlement terms are not public). Venue mattered twice over: the W.D. Tex. filing under Judge Albright was a classic patentee-friendly venue play, while Apple's successful transfer to N.D. Cal. and the PTAB's § 314(a) discretion (which is unreviewable on appeal) shaped the outcome. The case is notable because (1) it is a textbook NPE/PAE assertion pattern — a legacy voice-tech holder monetizing early-2000s patents against major platform companies; (2) the IPR linkage failed for petitioners: Apple's IPR2022-00950 and a parallel Microsoft IPR on the same patent (IPR2022-00137, challenging claims 1–2, institution denied May 11, 2022) were both denied, leaving the patents enforceable; and (3) it illustrates how rapidly voice-assistant patent disputes can resolve once moved out of W.D. Tex., while the absence of a merits invalidity ruling leaves residual exposure for the broader voice-UI industry. Caveats: the panel composition for IPR2022-00950 is not confirmed in my sources, and the dismissal's underlying terms were not disclosed in the public record.

Apple Inc. v. Parus Holdings, Inc. — Key Legal Developments & Outcome

Important framing note. The caption in the case metadata is the PTAB proceeding IPR2022-00950 (Apple as petitioner). The underlying patent infringement litigation runs the other direction — Parus Holdings, Inc. v. Apple Inc., No. 6:21-cv-00968-ADA (W.D. Tex., Waco Div., Judge Alan D. Albright), filed 2021-09-17, asserting U.S. Patent Nos. 6,721,705 ("'705") and 8,185,402 ("'402") — later re-docketed in the Northern District of California as 3:22-cv-07514 (Judge Vince Chhabria) after transfer. The '705 patent was the subject of IPR2022-00950; a parallel IPR (IPR2022-00948, on the '314 patent) was terminated by settlement in March 2023. Below is the chronology, with the PTAB proceedings woven in where they affected the litigation.

---

1. Filing & initial pleadings

• 2021-09-17 — Complaint filed. Parus sued Apple in the W.D. Tex. (Waco), No. 6:21-cv-00968-ADA, alleging willful infringement of the '705 and '402 patents (both titled Robust Voice Browser System and Voice Activated Device Controller) by Siri-enabled devices (iPhone, iPad, iPod, Mac, HomePod). Parus demanded a jury trial, damages, treble damages for willfulness, attorneys' fees, and a permanent injunction. (ECF 1, with Ex. 1 = '705 patent, Ex. 2 = '402 patent; UniCourt/DocketAlarm docket summaries; Parus press release of 2021-09-17 via TMCnet.)
• 2021-09-20 — Parus attorney appearances (Michael J. McNamara, Michael Renaud, et al., McKool Smith; UniCourt).
• 2021-10/11 — Apple appearances. Apple's counsel (including Fahd Patel, H. Christopher Han, Hector Gallegos, J. Stephen Ravel, Rose Lee, Bita Rahebi, Karina Pundeff) entered appearances; pro hac vice orders entered 2021-10-29 through 2021-11-02 (ECF 28–30; UniCourt).
• 2021-11-05 — First Amended Complaint. Parus moved unopposed for leave to amend (ECF 31); granted by text order 2021-11-12, with Apple's answer due 2021-12-13 (UniCourt docket).
• Answer and counterclaims. Apple answered and asserted defenses/counterclaims (the later dismissal order expressly extinguished "Apple's counterclaims and defenses" — PatSnap case summary), though I could not independently confirm the specific answer/counterclaim docket entries in the sources available. Flag: counterclaim specifics (e.g., declaratory judgment of non-infringement/invalidity) are inferred, not directly sourced.

2. Pre-trial motions of substance

• 2022-04-07 — Apple's Motion to Transfer under 28 U.S.C. § 1404(a) (ECF 44, sealed, "Motion to Transfer for Forum Non Conveniens"). Apple sought transfer from W.D. Tex. to N.D. Cal., relying heavily on a venue declaration from Apple financial manager Mark Rollins plus supplemental declarations (Casetext opinion in Parus Holdings Inc. v. Apple Inc.; WDTX docket).
• 2022-08-15 — Discovery hearing before Judge Albright (transcript filed 2022-09-30, ECF 88).
• 2022-09-22/26 — Briefing extensions; Markman pushed out. Joint motion to extend transfer briefing and reset the Markman hearing (ECF 85) granted 2022-09-26 (ECF 86), resetting the Markman hearing to 2022-12-15.
• 2022-09-22 — Parus's response in opposition to transfer (ECF 83, sealed; redacted public version ECF 87, 2022-09-29; supporting affidavits ECF 84). Parus attacked the Rollins declaration as unreliable, citing Judge Albright's prior criticism of Rollins in Scramoge (Casetext opinion).
• 2022-10-06/13 — Apple's reply (ECF 89, sealed; redacted declaration ECF 90 and reply ECF 91).
• 2022-11-08 — Counsel withdrawal. H. Christopher Han (Apple) withdrew (ECF 75 granted).
• 2022-11-29 — Transfer GRANTED. Judge Albright entered a sealed order (ECF 92) granting Apple's § 1404(a) motion; the case was transferred out to N.D. Cal. the same day, with the AO-120 patent report filed and transfer acknowledged 2022-11-30 (WDTX docket entries; the substantive opinion is the one published on Casetext, which applies the Fifth Circuit Volkswagen factors and finds Rollins "credible but limited" while analyzing NDCA as the proper transferee forum). A further WDTX order issued 2022-12-08 (ECF 94).
• No motion to dismiss, no motion to stay pending IPR, and no summary judgment motions appear in the docket records I found; the case was transferred and settled before those stages. Flag: absence of such motions is based on the docket summaries reviewed, not a full PACER run.

3. Claim construction (Markman)

• A Markman hearing was originally set and then reset to 2022-12-15 (ECF 86, 2022-09-26). Because the case was transferred on 2022-11-29 and then dismissed in early 2023, no Markman order was ever issued in W.D. Tex., and none occurred in N.D. Cal. before dismissal. Claim construction never produced a substantive ruling.

4. Discovery milestones with strategic significance

• 2022-08-15 — Discovery hearing before Judge Albright (transcript filed 2022-09-30, ECF 88) — the main discovery event visible in the WDTX docket.
• 2022-10-07 — Coordinated invalidity contentions. Apple, Microsoft, Google, and Samsung served joint Amended Preliminary Invalidity Contentions across the related Parus WDTX cases, challenging priority dates (Parus alleged conception 1998-10-13 / reduction to practice 2000-02-04) and mapping invalidity for the asserted claims. Against Apple, Parus had asserted the '705 (claims 1–4), '402 (claims 1–15), '190, and '314 patents (PTACTS filing, Ex. 1016/Invalidity Contentions). This shows the case was being litigated as part of a coordinated multi-defendant Parus campaign, and that discovery/claim-narrowing was still at the contention stage when the transfer motion intervened.
• No depositions or expert discovery milestones are documented in the sources reviewed; the transfer fight dominated the litigation calendar through fall 2022.

5. Trial, verdict, post-trial motions

• No trial occurred; no verdict. The case was transferred before the scheduled Markman hearing and dismissed before any trial setting. There were consequently no JMOL, new-trial, or fee motions in the district court.

6. Final disposition — settlement and dismissal

• 2022-11-30 — Case re-docketed in N.D. Cal. as Parus Holdings Inc. v. Apple Inc., No. 3:22-cv-07514 (Judge Vince Chhabria) upon receipt of the WDTX transfer (PatSnap; WDTX docket transfer entries).
• 2023-02-03 — Dismissal with prejudice. The N.D. Cal. action was dismissed with prejudice, with each party bearing its own attorneys' fees and costs — a stipulated, negotiated exit consistent with a confidential settlement; no invalidity or non-infringement findings were entered, and both patents remained enforceable against third parties (PatSnap case summary of 3:22-cv-07514). Terms of the settlement were not disclosed.
• The PTAB filings in March 2023 confirm a global settlement of the Apple–Parus dispute (see below).

7. Parallel PTAB IPR/PGR proceedings and their effect

• IPR2022-00950 — Apple Inc. v. Parus Holdings, Inc. ('705 patent), petition filed 2022-05-05.
  • Apple challenged claims 1–4 of the '705 patent (the very claims Parus asserted against Apple) on two grounds: (1) Brown + Shuster, and (2) a Whitley/Brown combination (per Apple's rehearing request, DocketAlarm).
  • 2022-12-06 — Institution DENIED. The Board denied institution under 35 U.S.C. § 314(a) (IPR2022-00950, Paper 7, "Decision Denying Institution of Inter Partes Review"), finding Apple failed to show a reasonable likelihood of prevailing.
  • 2023-01-06 — Apple's Request for Rehearing under 37 C.F.R. § 42.71(d), arguing the Board misapprehended the petition and adopted Patent Owner's mischaracterizations of Brown (DocketAlarm). Flag: I could not confirm the Board's ruling on the rehearing request from the sources retrieved; it was likely mooted or denied in the wake of the parties' settlement.
  • Google Patents metadata labels IPR2022-00950 "institution denied; settlement" — the "settlement" tag reflects the parties' global resolution (announced in the related IPR in March 2023), even though the '705 IPR itself ended with the institution denial.
• IPR2022-00948 — Apple Inc. v. Parus Holdings, Inc. ('314 patent, U.S. 9,769,314).
  • 2023-03-03 — Settlement termination at the PTAB. Apple and Parus jointly moved to terminate IPR2022-00948 "in light of the parties' resolution of their dispute," filing the settlement agreement and a joint request to treat it as business confidential information under 35 U.S.C. § 317(b) and 37 C.F.R. § 42.74(c) (IPR2022-00948, Paper 10, 2023-03-03; McKool Smith for Parus, Haynes and Boone for Apple). This confirms a global settlement of the Apple–Parus voice-browser litigation, including the district case and the parallel IPRs.
• Effect on the litigation: Apple's IPR filings did not produce a stay of the WDTX case (no stay motion is evident in the docket); instead, the district case proceeded toward transfer and settlement while the IPRs were pending. The denial of institution on the '705 patent (2022-12-06) — after the case had already been transferred to N.D. Cal. — was effectively mooted by the 2023-02-03 dismissal with prejudice.
• Broader context (separate, earlier Parus–Apple dispute): In the earlier Parus v. Apple case (No. 6:19-cv-00432, W.D. Tex., asserting the '431 and '084 patents), the Federal Circuit issued a writ of mandamus in August 2020 directing Judge Albright to transfer to N.D. Cal. (In re Apple), and in early September 2021 the PTAB rejected Apple's IPR challenges to those Parus patents — the backdrop Parus cited in its 2021-09-17 press release announcing the second lawsuit that became this case. These involve different patents and are included only for context.

Bottom line

The litigation was a two-front fight that ended in a global settlement:

1. District court: Parus's 2021-09-17 WDTX suit (6:21-cv-00968-ADA) asserting the '705 and '402 patents against Siri products; Apple answered with defenses/counterclaims and moved to transfer (2022-04-07). After contested briefing and a discovery hearing, Judge Albright granted transfer to N.D. Cal. on 2022-11-29; the case (3:22-cv-07514, Chhabria) was dismissed with prejudice on 2023-02-03, each side bearing its own costs — no Markman, no trial, no merits ruling.
2. PTAB: Apple's IPR on the '705 patent (IPR2022-00950) was denied institution on 2022-12-06; Apple's January 2023 rehearing request had no confirmed public ruling. The parallel IPR on the '314 patent (IPR2022-00948) was terminated by joint motion on 2023-03-03 reflecting the confidential settlement agreement.

Caveats: Docket-entry numbers for Apple's answer/counterclaims and the specific text of the sealed transfer order were not directly verifiable from the sources available; the rehearing outcome in IPR2022-00950 and the absence of certain motions are inferences from the docket summaries and coverage cited.

Key sources: WDTX docket for 6:21-cv-00968 (UniCourt/DocketAlarm/Gaelfront docket update pages); Casetext opinion in Parus Holdings Inc. v. Apple Inc. (transfer order); IPR2022-00950 Papers 7 (institution denial, 2022-12-06) and rehearing request (2023-01-06) via DocketAlarm; IPR2022-00948 Paper 10 (joint request re settlement agreement, 2023-03-03) via DocketAlarm; PatSnap litigation summary of 3:22-cv-07514 (dismissal 2023-02-03); Parus press release of 2021-09-17 (TMCnet/TheStreet); joint Amended Preliminary Invalidity Contentions dated 2022-10-07 (PTACTS).

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

I've found initial coverage from AppleInsider, TheStreet, TMCnet, Voicebot.ai, and PatSnap. Let me dig for coverage of the IPR denial, transfer, and settlement phases.

Press coverage of Apple v. Parus Holdings / Parus v. Apple ('705 patent)

What the press reported — the filing stage. The most detailed coverage came at the September 2021 filing of the underlying W.D. Tex. suit (6:21-cv-00968), which was the '705 patent's entry into public view. AppleInsider reported on 2021-09-21 that patent-holding firm Parus claimed Siri infringes U.S. Patent Nos. 6,721,705 and 8,185,402, both titled "Robust voice browser system and voice activated device controller"; it explained that the '705 was filed in 2001 by Webley Systems, granted in 2004, and acquired by Parus in 2004, and that the patents cover accessing and ranking web data through a maintained database via natural-language voice commands. AppleInsider's piece — the source most later coverage drew on — noted the complaint's specifics: Siri's reliance on web crawlers including Applebot, Bing, and Google; the naming of "all Siri-enabled devices, from iPhone to Mac and HomePod" as infringing instrumentalities; and that the '705's household-device-control claims (cameras, lighting, TVs) were "not asserted in the immediate action." TheStreet reported on 2021-09-17 that Parus alleged "willful" infringement and demanded treble damages, attorneys' fees, and a permanent injunction, and quoted Parus chairman/CEO Taj Reneau: "It's Parus's preference to license its foundational technology but will vigorously defend its patent portfolio as necessary." TMCnet carried Parus's own PRNewswire release the same day, which framed the case as a "second patent lawsuit against Apple," touted a PTAB victory Parus had just secured against Apple on other patents, and sought "damages against Apple for all of its infringing sales." The AppleInsider story was also syndicated into Chinese tech press (e.g., c114.com.cn and ChinaZ, both 2021-09-22), which emphasized the willfulness/treble-damages demands.

Why outlets considered it significant. Coverage framed the case as part of a coordinated voice-assistant patent campaign rather than an isolated dispute. Voicebot.ai, covering Parus's earlier 2019 wave against Apple, Google, LG, and Samsung (different patents, the '431/'084 family), noted Siri was "at the center" and catalogued the accused product lines (iPhone 6s onward, Apple Watch, HomePod, 2018 MacBook Pro/Air, iMac Pro, CarPlay); it also supplied the market-context numbers that AppleInsider-era coverage lacked — Apple's $24.9 million 2016 settlement with Dynamic Advances/Rensselaer over Siri voice features and the ~$31 million Qualcomm jury verdict. TheStreet and TMCnet both flagged the strategic backdrop that Parus itself emphasized: the suit came right after the PTAB had rejected Apple's earlier IPR challenges to Parus's '431/'084 patents, positioning the new '705/'402 assertions as an aggressive second front against a company whose voice assistant had already been a repeated patent target.

Coverage of the resolution — and what it adds beyond the court record. There is essentially no mainstream legal-press coverage (no Reuters, Bloomberg Law, or Law360 articles surfaced in my searches) of the two decisive procedural events — Judge Albright's 2022-11-29 transfer order and the PTAB's 2022-12-06 institution denial in IPR2022-00950. The resolution phase is documented chiefly by PatSnap's AI-generated litigation analyses, which report that the re-filed N.D. Cal. case (3:22-cv-07514) was dismissed with prejudice on 2023-02-03 with each party bearing its own fees and costs, 65 days after filing — "well below" the N.D. Cal. median for patent cases — and stress that the '705 and '402 patents "exited this case with no invalidity finding" and "remain valid and enforceable against third parties." PatSnap's companion analysis of the related Federal Circuit appeal (Apple Inc. v. Parus Holdings, Inc., No. 22-1144, involving the separate '084 patent) reports a 2023-03-07 dismissal under Fed. R. App. P. 42(b) with each side bearing its own costs — a "procedural termination" that "establishes no appellate precedent."

Where accounts diverge and gaps to note. The main discrepancy is labeling: Google Patents metadata and docket aggregators tag IPR2022-00950 as "settlement," but the PTAB's own record shows the '705 IPR ended in a December 6, 2022 institution denial (per the Board's Paper 7, cited in DocketAlarm's docket for IPR2022-00950, and Apple's January 6, 2023 rehearing request); the "settled" tag reflects the parties' later global resolution confirmed by the with-prejudice dismissal and the March 2023 settlement terminations of the companion IPRs (IPR2022-01542 on the '190 patent and IPR2023-00303 on the '402 patent, both "Terminated-Settled" per DocketAlarm). Analyst commentary goes beyond the record in inferring strategy from the 65-day dismissal — PatSnap reads it as evidence of "high leverage for well-resourced defendants" and warns of "active FTO risk" for the broader voice-UI industry — while no outlet reported any damages figure, settlement amount, or licensing terms, and Parus's CEO statement about preferring to "license its foundational technology" remains the only executive explanation on the public record.

Important framing caveat

The case in the metadata — IPR2022-00950, Apple Inc. v. Parus Holdings, Inc. (PTAB) — is not a patent infringement case. It is an inter partes review petition filed by Apple on May 5, 2022, challenging U.S. Patent No. 6,721,705 ("the '705 patent"). In IPR terminology there is no "plaintiff"; there is a petitioner (Apple) and a patent owner (Parus). The PTAB denied institution on December 6, 2022, and Google Patents metadata lists the proceeding as terminated/settled.

The actual patent infringement cases between these parties over the '705 patent are:

• Parus Holdings Inc. v. Apple Inc., No. 6:21-cv-00968-ADA (W.D. Tex., Judge Alan D. Albright), filed Sept. 17, 2021 — asserting the '705 and '402 patents (Patexia related-case listing; UniCourt docket PC-db5-parus-holdings-inc-v-apple-inc-1023047).
• Parus Holdings Inc. v. Apple Inc., No. 3:22-cv-07514 (N.D. Cal.), filed Nov. 30, 2022 — dismissed with prejudice on Feb. 3, 2023, each side bearing its own fees (PatSnap litigation summary).

In those cases, the plaintiff is Parus Holdings, Inc. (not Apple). Below is counsel of record for the plaintiff, Parus, based on the public docket of 6:21-cv-00968 (UniCourt attorney/firm details and notice-of-appearance entries).

---

Plaintiff (Parus Holdings, Inc.) — Counsel of Record, W.D. Tex. 6:21-cv-00968

Per the UniCourt docket, Parus's plaintiff-side attorneys of record were:

1. T. John Ward, Jr. — Texas patent litigator and former W.D. Tex. district judge; founder of Ward, Smith & Hill, PLLC (Longview, TX). Appeared for Parus in the related W.D. Tex. Google cases as well (UniCourt, Parus Holdings Inc. v. Google LLC). Role: local/Texas counsel. Notable: as a judge he presided over the "epic" early patent cases in the Eastern District of Texas; his firm is a fixture in W.D. Tex. patent litigation.
2. Andrea L. Fair — Ward, Smith & Hill, PLLC (Longview, TX). Texas local counsel; frequent Albright-court patent litigator. (Firm affiliation inferred from the Ward Smith team structure and is consistent with the docket grouping; I could not independently verify her firm page in the available snippets.)
3. Charles Everingham IV — Ward, Smith & Hill, PLLC (Longview, TX). Texas local counsel; known for W.D. Tex. patent work. (Same verification caveat as above.)
4. Claire Abernathy Henry — Ward, Smith & Hill, PLLC (Longview, TX). Texas local counsel. (Same caveat.)
5. Sean M. Casey — Ward, Smith & Hill, PLLC (Longview, TX). Texas local counsel. (Same caveat.)
6. Michael T. Renaud — Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. (Boston, MA). Chair of Mintz's Intellectual Property Division; lead/co-counsel on the Parus enforcement campaign against Apple, Google, Samsung, Microsoft, and Amazon. Notable: led the DivX IP litigation team; his handling of the Parus cases is now itself the subject of a legal-malpractice suit, Parus Holdings, Inc. v. Mintz, Levin, Cohen, Ferris, Glovsky and Popeo, P.C. et al., No. 1:25-cv-01722 (W.D. Tex., filed Oct. 24, 2025), which names Renaud and McNamara individually (Law.com Radar; PACER Monitor; Reuters filing PDF).
7. Michael J. McNamara — Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. (Boston, MA). Member of Mintz's IP litigation group; co-lead for Parus. Mintz's own bio confirms McNamara's Mintz affiliation and his work on patent suits for DivX, ParkerVision, and others; the 2025 malpractice complaint likewise identifies him as a Mintz lawyer representing Parus in the Apple/Google/Amazon matters.

Roles: Based on the docket entries available (e.g., Docket #5, #6 — notices of appearance by Renaud and McNamara for Parus), the team functioned as Texas local counsel (Ward Smith & Hill) plus out-of-district lead litigation counsel (Mintz). I did not find an express docket designation of "lead counsel" vs. "of counsel" in the snippets available, so those role labels are my characterization of the standard structure rather than a verified docket designation.

---

For completeness: the IPR's counsel and Apple's district-court counsel

• IPR2022-00950 (PTAB): I could not verify from the available sources who signed the petition for Apple or the preliminary response for Parus (the USPTO PTAB docket/PTACTS would list lead and backup counsel). I am not going to name attorneys for that proceeding without a source — treat that as unverified.
• Apple's district-court defense counsel in 6:21-cv-00968 (listed as "Defendant Attorneys" on UniCourt): Fahd H. Patel, H. Christopher Han, Hector G. Gallegos, J. Stephen Ravel (Texas local), Rose S. Lee, Bita Rahebi, and Karina N. Pundeff (the last three appearing pro hac vice per docket entries #29, #30). I did not verify their firm affiliations from the available snippets, so I won't assign firms.

---

Key sourcing notes and caveats

• No fabrication: All seven Parus attorneys above come from the UniCourt docket for 6:21-cv-00968; Renaud's and McNamara's Mintz affiliations are corroborated by Mintz's own attorney bio and by the 2025 Parus-v.-Mintz malpractice filings. The Ward, Smith & Hill affiliations of Ward, Fair, Casey, Everingham, and Henry are consistent with the docket but were not directly confirmed in my available search snippets — verify against the firm's attorney directory before relying on them.
• "Settlement" status: The IPR2022-00950 termination on Dec. 6, 2022 was an institution denial (the Board did not institute); the "settlement" label in Google Patents metadata likely reflects the parties' broader resolution, evidenced by the Feb. 3, 2023 with-prejudice dismissal of the N.D. Cal. case (3:22-cv-07514) with each party bearing its own costs. The W.D. Tex. case (6:21-cv-00968) remained pending as of the UniCourt snapshot ("Pending – Other Pending") and was stayed during the related IPRs.
• If you need the exact lead/backup counsel designations from the IPR2022-00950 papers themselves, the authoritative source is the USPTO PTAB docket (PTACTS/PTAB E2E) or a full PACER/DocketAlarm download — I did not have access to those documents in this session.

Preliminary clarification on case posture

IPR2022-00950 is not a district-court patent infringement case — it is an inter partes review before the Patent Trial and Appeal Board, captioned Apple Inc. v. Parus Holdings, Inc. Apple is the petitioner; Parus Holdings, Inc. is the patent owner/respondent (the party defending the '705 patent). The IPR was filed May 5, 2022, institution was denied December 6, 2022, and Google Patents metadata lists the status as "settlement." Below I address both plausible readings of "defendant": Parus (patent owner defending the IPR) and Apple (defendant in the related district-court infringement suits).

1. Patent owner / respondent Parus Holdings, Inc. — McKool Smith P.C.

Firm-level representation (well sourced): McKool Smith P.C. publicly identified itself as Parus's counsel in this exact proceeding. In a February 8, 2023 press release touting its 2022 PTAB win rate, the firm listed as notable 2022 wins "Google v. Parus Holdings, Apple v. Parus Holdings, Kinaxis v. Blue Yonder Group, Inc., and Samsung v. RightQuestion, LLC," and stated it "represented 54 patent owners against PTAB petitioners in 2022," including Parus Holdings. (McKool Smith press release, "McKool Smith Notches Top PTAB Win Rate in 2022," Feb. 8, 2023; also reproduced at PRNewswire and on the firm's site.)

Attorneys known to lead Parus's PTAB defense in the parallel IPR wave (well sourced, but not individually confirmed for IPR2022-00950):

• John Campbell — Principal, McKool Smith (Dallas/Austin). His sworn declaration in the parallel Google LLC v. Parus Holdings, Inc. IPR2022-00805 states: "I am principal at McKool Smith P.C. I am lead counsel for Parus Holdings Inc. ('Parus') in the present Inter Partes Review (IPR) IPR2022-00805," and describes the coordinated sixteen-petition IPR wave filed by Google, Apple, Microsoft, and Samsung between November 2021 and December 2022 — which includes IPR2022-00950 (DocketAlarm exhibit 2007, Declaration of John Campbell, Sept. 19, 2023).
• Scott Hejny — Principal, McKool Smith (Dallas); per the same press release, he is "primarily responsible for heading up the firm's PTAB efforts."

Caveat — specific lead/back-up counsel of record: I was not able to retrieve the actual Mandatory Notices (paper) from the IPR2022-00950 docket in my searches (PTAB filings are on the USPTO's PTAB docket system, which wasn't directly accessible in the available search results). The named lead counsel and back-up counsel of record for Parus in IPR2022-00950 would appear in Parus's Mandatory Notices filed within 21 days of the petition (May 2022) and in any Patent Owner Preliminary Response. Because institution was denied on December 6, 2022, no Patent Owner Response was ever due, and the record is thin. I will not invent names: the only attorney whose role in the Parus-vs.-Big-Tech IPR wave is directly verified on the record is John Campbell (lead counsel in the related IPR2022-00805), and the firm-level representation is confirmed by McKool Smith's own announcement.

2. If you meant Apple as defendant in the underlying infringement cases

Apple was sued by Parus in parallel district-court cases asserting the '705 patent (and related '402 patent):

• Parus Holdings Inc. v. Apple Inc., No. 6:21-cv-00968 (W.D. Tex., filed Sept. 17, 2021, Judge Albright) — per the Unicourt docket summary, Apple's defense counsel of record included: Fahd H. Patel, H. Christopher Han, Hector G. Gallegos, J. Stephen Ravel, Rose S. Lee, Bita Rahebi, and Karina N. Pundeff (the latter two admitted pro hac vice per docket entries #29 and #30, Nov. 2021). The Unicourt page lists these as "Defendant Attorneys," but I could not confirm each attorney's firm from the available snippets and will not guess.
• The W.D. Tex. case was later resolved; a related N.D. Cal. case (No. 3:22-cv-07514, filed Nov. 30, 2022) asserting the '705 and '402 patents was dismissed with prejudice on Feb. 3, 2023, each party bearing its own fees (per PatSnap's case summary).

Bottom line

• In IPR2022-00950 (the case in your metadata), the party defending the patent — Parus Holdings, Inc. — was represented by McKool Smith P.C., whose principals John Campbell and Scott Hejny led the firm's Parus PTAB defense. Specific lead/back-up counsel of record for this IPR number should be confirmed against Parus's Mandatory Notices on the USPTO PTAB docket; I could not pull that specific paper in my searches.
• If "defendant" means Apple in the underlying infringement suits, Apple's recorded defense attorneys in W.D. Tex. 6:21-cv-00968 were Patel, Han, Gallegos, Ravel, Lee, Rahebi, and Pundeff (firms not confirmed from the available record).
