Speech Transcription LLC v. Sondrel Inc. — Voluntarily Dismissed Without Prejudice
Speech Transcription LLC asserted US8938799B2 against Sondrel’s SFA100 chip in the Northern District of California. The plaintiff voluntarily dismissed without prejudice after just 175 days — before Sondrel filed any responsive pleading, leaving the door open for potential refiling.
Early voluntary exit in a speech-tech chip IP dispute
Speech Transcription LLC filed suit against Sondrel Inc. on 17 August 2023 in the Northern District of California before Judge Vince Chhabria, asserting patent US8938799B2 against Sondrel’s SFA100 product. Sondrel is a semiconductor and ASIC design company, and the SFA100 appears to relate to its audio and speech-processing product portfolio. The case was brought by Garteiser Honea, a Texas-based IP trial boutique with a known record of assertion-side patent litigation.
On 8 February 2024 — just 175 days after filing — Speech Transcription LLC filed a notice of voluntary dismissal under FRCP Rule 41(a)(1)(A)(i), dismissing the action without prejudice. Because Sondrel had filed neither an answer nor a motion to dismiss, the plaintiff was entitled to dismiss as of right without court approval. The dismissal was entered without prejudice, meaning the claims survive the dismissal and may be re-asserted in a future action.
The speed of resolution — less than six months, with no responsive pleading from Sondrel — is consistent with several possible dynamics: early licensing or settlement negotiations concluding off the record, a strategic decision to refile in a more favourable venue, or a reassessment of claim strength after pre-litigation due diligence. The public record is silent on the reason for dismissal. The without-prejudice designation means practitioners and competitors of Sondrel should treat this as an unresolved IP risk rather than a concluded matter.
Filing to voluntary dismissal in 175 days
175 days — resolved before any responsive pleading was filed
Voluntary dismissal without prejudice — what it means for both sides
Rule 41(a)(1)(A)(i): dismissal as of right
FRCP Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order at any time before the opposing party serves an answer or a motion to dismiss. Because Sondrel filed neither, Speech Transcription LLC could exit unilaterally. No judicial approval was required, and no findings were made on the merits of the infringement claims.
No court order neededWithout prejudice: the case is not over
A dismissal without prejudice does not extinguish the underlying claims. Speech Transcription LLC retains the right to refile the same patent claims against Sondrel in another action, subject to applicable statutes of limitations. This is legally distinct from a dismissal with prejudice, which would bar refiling. The public record does not state whether any settlement, licensing agreement, or other resolution was reached — that information, if any exists, is private.
Refiling remains possible175 days with no answer filed — what this suggests
The case closed before Sondrel submitted any formal response. This timeline is consistent with parties engaging in confidential licensing or settlement discussions shortly after service, or with the plaintiff reassessing its litigation strategy. Early dismissals of this type frequently — though not always — reflect off-record resolution. No public evidence confirms or denies a licensing outcome in this matter.
Pre-answer exitN.D. California: a high-stakes patent forum
The Northern District of California is a technically sophisticated forum often chosen for semiconductor and software IP disputes given the concentration of relevant industry and judicial expertise in the region. Filing here against an ASIC design company like Sondrel signals plaintiff confidence in a tech-literate bench. Judge Vince Chhabria presided; his docket is active with complex commercial and IP matters.

Stipulation of dismissal — official text
The dismissal notice invokes FRCP 41(a)(1)(A)(i) and explicitly notes Sondrel had filed neither an answer nor a motion to dismiss — confirming the plaintiff’s unilateral right to exit. The without-prejudice designation is legally significant: no merits determination was made, the patent’s validity was never tested in this proceeding, and Speech Transcription LLC retains full standing to reassert US8938799B2 against Sondrel or others. For Sondrel, the dismissal provides procedural relief but no legal protection against future assertion.
US8938799B2 — Speech transcription processing patent
US8938799B2, filed under application number US11/597486, is a granted US utility patent held by Speech Transcription LLC covering technology in the speech transcription domain. The patent’s grant number prefix (8,938,799) places it in a cohort issued in the mid-2010s, suggesting an application filing in the mid-2000s — a period of active foundational patent development in digital speech processing. The asserted product, Sondrel’s SFA100, is an ASIC-class chip, indicating the plaintiff’s theory likely involves hardware-implemented transcription or speech recognition functionality.
Speech transcription patents of this vintage can carry broad independent claims covering signal processing pipelines, phoneme or feature extraction methods, or decode architectures — making them relevant to a wide range of audio-capable chips and systems-on-chip. For semiconductor vendors, IP aggregators holding patents in this space represent persistent licensing pressure. The fact that this patent was asserted against a dedicated ASIC designer suggests the claim scope may reach hardware implementations, not merely software stacks — broadening potential defendant pools across the chip design industry.
Should your team run an FTO against US8938799B2?
If your organisation designs, integrates, or distributes chips, SoCs, or DSPs with speech transcription, automatic speech recognition, or voice-processing functionality, US8938799B2 is a patent that warrants direct FTO review. The plaintiff’s willingness to assert against a specialised ASIC vendor like Sondrel indicates a claim interpretation broad enough to reach hardware-level implementations — not just software or cloud-based speech engines.
PatSnap Eureka’s FTO Search Agent can map the independent and dependent claims of US8938799B2 against your product architecture, flag prior art that may narrow enforceability, and identify any continuation or divisional patents in the same family that could extend the assertion risk. Setting a claim-change monitor on this patent family ensures your team is notified of any prosecution activity, reissue, or related application that could shift the risk profile before your next product launch.

What this case signals for the speech-tech and semiconductor IP landscape
A pre-answer dismissal without prejudice is rarely the end of the story — especially when the asserted patent remains active.
US8938799B2 remains a live enforcement risk for audio-chip developers
The dismissal without prejudice means Speech Transcription LLC’s patent is not exhausted against Sondrel or any other target. Companies developing or integrating speech transcription hardware — including ASIC and SoC vendors — should treat this patent as an active assertion risk and conduct FTO analysis before product launch.

Speech v Sondrel — key questions answered
Speech Transcription LLC filed a patent infringement suit against Sondrel Inc. in the Northern District of California on 17 August 2023, asserting US8938799B2 against the Sondrel SFA100. The plaintiff voluntarily dismissed the case without prejudice on 8 February 2024 under FRCP Rule 41(a)(1)(A)(i), before Sondrel filed any answer or motion to dismiss.
Dismissed without prejudice means Speech Transcription LLC’s infringement claims against Sondrel were not decided on the merits and the plaintiff retains the right to refile the same claims in a future action. Sondrel received no court-issued finding of non-infringement or invalidity, meaning the patent risk is unresolved from a legal standpoint.
US8938799B2 is a granted US utility patent held by Speech Transcription LLC covering speech transcription technology, filed under application US11/597486. It was asserted against Sondrel’s SFA100, an ASIC chip, suggesting the plaintiff’s infringement theory extended to hardware-implemented speech processing functionality. No claim construction or merits ruling was issued in this case.
The public record does not state the reason for the early dismissal. Common explanations for pre-answer voluntary dismissals include confidential licensing or settlement agreements reached off the record, a strategic decision to refile in a different venue, or a reassessment of litigation strategy. The 175-day timeline without any responsive pleading from Sondrel is consistent with early-stage negotiation, but no confirmation is available from the docket.
