Summary

This is an active patent infringement lawsuit filed by SoundClear Technologies LLC against Google, LLC. The case was transferred from the Alexandria Division (1:24-cv-01281) to the Richmond Division, where it continues under this docket number.

Case overview & background

Plain-language overview of the case: parties, accused product, patents at issue, and why the suit matters.

This is an active patent infringement lawsuit where SoundClear Technologies LLC, identified as a non-practicing entity (NPE) or patent assertion entity (PAE), has accused Google, LLC, a major technology company, of infringing patents related to voice recognition and audio processing. SoundClear Technologies LLC was formed in Delaware and Virginia in mid-2023, and subsequently acquired the asserted patents from JVCKenwood. The litigation targets Google's extensive voice-AI product ecosystem, including the Google Home product line (e.g., Google Home, Nest Audio, Nest Hub, Nest Mini, Home Max), all generations of Google Nexus/Pixel devices, and various Google Assistant-integrated smart screen products. The asserted patents include U.S. Patent Nos. 11,069,337, 11,244,675, and 9,223,487, which generally pertain to voice recognition and audio processing technologies, encompassing features such as noise reduction, speech detection and processing, and volume control. Patent '337 is described as expanding claim coverage in this technological domain, '675 as likely directed to refined voice signal processing or noise cancellation, and '487 as suggesting foundational claims in the voice recognition or audio processing pipeline.

The case, originally filed on July 25, 2024, in the Alexandria Division, was quickly transferred to the Richmond Division of the Virginia Eastern District Court (EDVA), where it proceeds under case number 3:24-cv-00540 before District Judge M. Hannah Lauck. The EDVA is famously known as the "Rocket Docket" due to its expedited litigation timeline, boasting a median "file to trial" duration of just 16.4 months in 2023. This venue's strict enforcement of deadlines and rapid resolution of motions makes it an attractive forum for plaintiffs seeking swift litigation outcomes.

This case is notable for several reasons, including SoundClear's apparent nature as an NPE asserting patents acquired from a third party against a tech giant. The broad scope of accused products, spanning Google's entire voice-AI hardware and software stack, highlights the intensified monetization pressure within the smart speaker and voice AI market, a significant battleground for audio and voice recognition patent assertions dominated by companies like Google. Furthermore, the litigation has been stayed pending inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB). Google has initiated IPRs, including IPR2025-01597 against U.S. Patent No. 11,069,337, which was instituted on March 17, 2026. Amazon, a defendant in a parallel SoundClear case, also filed an IPR against the '337 patent (IPR2025-00565), which proceeded to trial. These IPRs, alongside prior Alice challenges in a related Amazon case, suggest potential vulnerabilities for the asserted patents regarding patent eligibility.

Key legal developments & outcome

Major rulings, motions, claim construction, settlements, and the present posture or final disposition.

The patent infringement lawsuit by SoundClear Technologies LLC against Google, LLC (3:24-cv-00540) has seen several key developments since its filing.

Filing & Initial Pleadings:

  • Complaint Filed (2024-07-25): SoundClear Technologies LLC initiated a patent infringement action against Google LLC in the Virginia Eastern District Court, initially assigned Case No. 1:24-cv-01281. The complaint asserted three U.S. patents: 11,244,675 B2, 9,223,487 B2, and 11,069,337 B2, covering voice recognition and audio processing technologies. The accused products include Google Home, Google Nest Audio, Google Nest Hub (all generations), Google Nest Mini, Google Home Mini, Google Home Max, all Google Nexus/Pixel device generations, and Google Assistant smart screen products.
  • Case Transferred (2024-07-26): Within 24 hours of filing, the case was administratively transferred from the Alexandria Division (1:24-cv-01281) to the Richmond Division, where it was assigned the current Case No. 3:24-cv-00540. The Alexandria docket was closed due to this intradistrict transfer, and the substantive infringement action continues in the Richmond Division.

Pre-trial Motions of Substance:

  • Motion to Stay Pending Inter Partes Review (2025-04-18): Google LLC filed an Unopposed Motion to Stay Pending Inter Partes Review (IPR). The Court, presided over by District Judge M. Hannah Lauck, granted the motion on April 18, 2025. Although SoundClear initially stated it did not believe a stay was justified, it declined to oppose the motion due to particular circumstances, such as a similar stay granted in a parallel case against Amazon involving the same patents. The Court found that a stay would simplify the issues, given that a Markman hearing had not yet been set and the case was not set for trial.
  • Motions to Transfer for Convenience: Both Google and Amazon (in related cases) filed motions to transfer for convenience to the Northern District of California. In response, SoundClear identified its president and CTO. (Note: The outcome of Google's specific motion to transfer is not explicitly stated in the provided snippets, but the case remains in the Eastern District of Virginia as of current information).

Claim Construction (Markman) Outcomes:

  • As of the latest available information, a Markman hearing had not been set before the case was stayed pending IPR.

Discovery Milestones with Strategic Significance:

  • No specific strategically significant discovery milestones were detailed in the provided search results beyond the general understanding that "substantive litigation—including service on Google, answer deadlines, claim construction, and any Markman hearings—will proceed under Case No. 3:24cv540" prior to the stay.

Trial Events, Verdict, and Post-Trial Motions:

  • The case has not yet reached trial due to the stay pending IPR proceedings.

Settlement, Dismissal, Judgment, or Appeal:

  • The case is currently in an active litigation posture, stayed pending the resolution of IPR proceedings. There has been no merits-based verdict, settlement, or dismissal.

Parallel PTAB IPR/PGR Proceedings:

  • IPR2025-01597 (Filed 2025-09-29): Google LLC filed an Inter Partes Review (IPR) petition against U.S. Patent No. 11,069,337 B2. This IPR was instituted on March 17, 2026.
  • IPR2025-01177 (Filed 2025-11-25): Google LLC also filed an IPR petition concerning the asserted patents.
  • IPR2026-00073 (Filed 2025-11-17): Google LLC filed another IPR petition related to the asserted patents.
  • IPR2025-00565: A separate IPR proceeding (IPR2025-00565) concerning patent 11,069,337 B2 was filed by Amazon as the petitioner against SoundClear Technologies LLC as the patent owner, and an oral argument date has been set.

The stay granted by the court on April 18, 2025, is directly linked to the existence of these IPR proceedings, indicating their significant effect on the litigation by pausing the district court case.

Plaintiff representatives

Counsel of record for the plaintiff(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

I'll research plaintiff-side counsel for SoundClear Technologies LLC in this case.

Let me disentangle the dockets and verify exactly which counsel appeared in 3:24-cv-00540 (Richmond), as opposed to the parallel Norfolk/Alexandria actions.

Now let me pin down bios/roles for the Daignault Iyer team and check for any additional plaintiff-side counsel (e.g., Austin Ciuffo, Spencer Fane).

Plaintiff-side counsel of record — SoundClear Technologies LLC v. Google LLC, 3:24-cv-00540-MHL (E.D. Va., Richmond Div.)

Bottom line: All plaintiff-side counsel of record are from a single firm, Daignault Iyer LLP (8229 Boone Blvd., Suite 450, Vienna, VA 22182; earlier filings in the related first-filed case used 8618 Westwood Center Dr., Suite 150, Vienna, VA). There is no in-house legal department for plaintiff (SoundClear is an NPE; its Rule 7.1 statement says it is wholly owned by SoundClear LLC), and no second outside firm has entered an appearance for plaintiff in this docket.

Attorneys of record in 3:24-cv-00540

Attorney Role Firm / office Notes
Kevin H. Sprenger (VSB No. 98588; USPTO Reg. No. 79,466) Local counsel / counsel of record — certifying local counsel for every pro hac vice application filed by plaintiff in this case Daignault Iyer LLP, Vienna, VA Signed the Notice of Appearance on the filing date (ECF 6, July 25, 2024) and has served as the EDVA anchor for the SoundClear team across the cognate dockets; also backup counsel for SoundClear in the parallel PTAB proceedings. Argued alongside Steven Reynolds at the Amazon stay hearing in SoundClear v. Amazon, No. 1:24-cv-1283 (Tr. at 3).
Chandran B. Iyer (VSB No. 94100; USPTO Reg. No. 48,434) Counsel of record / name partner Daignault Iyer LLP, Vienna, VA Firm name partner and registered patent attorney; signed SoundClear's Rule 7.1 disclosure in the related first-filed action and is on the certificate of service for plaintiff in this case. Caveat: the CM/ECF filer attribution on the Richmond docket reads "Iyer, Ramachandran" (see below).
Steven J. "Steve" Reynolds (USPTO Reg. No. 61,445; not Virginia-barred — admitted pro hac vice) Lead trial counsel / lead PTAB counsel Daignault Iyer LLP, Vienna, VA Admitted PHV in this case by order at ECF 18 (fall 2024; fee receipt AVAEDC-9773549). J.D., Univ. of Illinois College of Law (2007); recognized in Best Lawyers in America since 2023 for Litigation–IP and Litigation–Patent; designated Lead Counsel for SoundClear in the IPR mandatory notices (Oct. 20, 2025) and argued the venue-discovery motion in the parallel Google/Amazon EDVA cases.
Ronald M. Daignault (not admitted in Virginia — PHV only) Of counsel / name partner Daignault Iyer LLP, Vienna, VA PHV motion certified by Sprenger on Dec. 16, 2024; granted by Judge M. Hannah Lauck on Dec. 17, 2024 (receipt AVAEDC-9903802). Listed as backup counsel on Daignault Iyer PTAB powers of attorney and mandatory notices for SoundClear-related IPRs.
James Joseph Hatton Pro hac vice counsel Daignault Iyer LLP, Vienna, VA PHV application filed Nov. 7, 2024 (receipt AVAEDC-9837696) with Sprenger as certifying local counsel; granted. Also listed on plaintiff's service list in this docket. No independent public bio verified.
Matthew R. Harkins Pro hac vice counsel Daignault Iyer LLP, Vienna, VA PHV application filed Nov. 7, 2024 (receipt AVAEDC-9837707), certified by Sprenger; granted. Also appears on plaintiff's service list. No independent public bio verified.
Shailendra Maheshwari Pro hac vice counsel Firm affiliation not confirmed by available sources (PHV sponsored by Daignault Iyer's Sprenger) PHV application filed Jan. 16, 2025 (receipt AVAEDC-9951722); granted. Appears among plaintiff-side counsel on later filings/service lists.
Austin J. Ciuffo Pro hac vice counsel (service list) Later listed at Spencer Fane LLP Appears as "Austin Ciuffo (pro hac vice)" on plaintiff's certificate of service in this case (the Google motion-to-stay papers) and was admitted PHV in the parallel Norfolk action (receipt AVAEDC-9837675). The PacerMonitor counsel list for the transferred N.D. Cal. case shows him at Spencer Fane LLP, suggesting a post-2025 firm move — worth re-verifying against PACER if his appearance status matters.
"Ramachandran Iyer" (docket/CM/ECF filer name) Counsel of record — filed the Complaint (ECF 1), Corporate Disclosure Statement (ECF 3), patent-report (ECF 4), proposed summons (ECF 2) and Notices of Appearance (ECF 5, 7) on July 25, 2024 Daignault Iyer LLP, Vienna, VA Open question I could not resolve from public sources: it is not clear whether "Ramachandran Iyer" is a separate Daignault Iyer attorney or the CM/ECF account name of Chandran B. Iyer (whose signature block, VSB No. 94100, appears on the same plaintiff filings). Justia's docket lists the plaintiff as "Represented By Kevin Sprenger / Ramachandran Iyer." Treat the two name forms as possibly the same person until PACER confirms.

PTAB-side counsel for the same patent owner (not district-court counsel of record)

For completeness, the Oct. 20, 2025 mandatory notices in the related IPRs designate Steven J. Reynolds (lead), Kevin H. Sprenger, Chandran B. Iyer, Erin Hadi (USPTO Reg. No. 79,904), and Louay Meroueh (USPTO Reg. No. 81,304), all of Daignault Iyer LLP, Vienna, VA. Hadi and Meroueh are flagged "not admitted in Virginia" and do not appear on the district-court docket — they are PTAB-only.

Sources and verification status

Flags against the previously generated sections (please reconcile)

  1. Defendant's counsel is wrong in the prior section. The prior "Defendant representatives" section names Gibson, Dunn & Crutcher. The actual 3:24-cv-00540 docket shows Paul Hastings LLP (Robert W. Unikel, Douglas L. Sawyer, Mark T. Smith — Chicago; Robert Laurenzi — New York; Joshua Yin — Palo Alto; Ariell N. Bratton — San Diego) with Kaufman & Canoles, P.C. (Stephen E. Noona, VSB No. 25367, Norfolk) as local counsel. Gibson Dunn does not appear on this docket.
  2. The stay was entered April 18, 2025 by Judge M. Hannah Lauck (Memorandum Opinion, ECF 50; https://cases.justia.com/federal/district-courts/virginia/vaedce/3:2024cv00540/557525/50/0.pdf), and Google's motion to dismiss (ECF 16) was denied without prejudice as part of the stay. The prior section's reference to an "April 18, 2025" filing of the stay motion should read April 8, 2025 motion (ECF 47) / April 18, 2025 ruling. Note the opinion contains a typo referring to the '337 patent as "the '854 patent," and misstates the complaint date as July 25, 2025 (should be 2024).
  3. Don't conflate dockets. The 3:31/4/18, 2025 stay and Judge Arenda L. Wright Allen's March 31, 2025 stay belong to the separate Norfolk case (2:24-cv-00321), which Google successfully transferred — it is now N.D. Cal. 3:26-cv-06222 (Judge Sallie Kim), transferred in on June 23, 2026. The Richmond case, 3:24-cv-00540, remains stayed in EDVA before Judge Lauck.
  4. The case metadata lists only the '337 patent, while the complaint and the stay opinion address three patents ('337, '675, '487). Treat the metadata's single-patent field as incomplete.

If you want, I can next pull the PACER docket sheet for 3:24-cv-00540 directly to (a) confirm whether "Ramachandran Iyer" and Chandran B. Iyer are the same person, and (b) confirm Ciuffo's current firm and whether he remains of record.
