EMM Innovations v. Lark Technologies: Patent Suit Ends in Dismissal With Prejudice
EMM Innovations LLC filed suit against Singapore-based Lark Technologies Pte. Ltd. in the Eastern District of Texas, asserting US10776756B2 against the Lark Suite of online collaboration tools. The parties jointly stipulated to dismiss all claims and counterclaims with prejudice after 422 days, with each side bearing its own legal costs.
Collaboration software patent claim ends quietly — but permanently
On July 30, 2024, EMM Innovations LLC filed a patent infringement action against Lark Technologies Pte. Ltd. in the U.S. District Court for the Eastern District of Texas before Judge Rodney Gilstrap. EMM alleged that the Lark Suite of online collaboration tools infringed US10776756B2, a patent directed to workflow and task management technology filed under application number US14/149904.
The case closed on September 25, 2025, when both parties jointly filed a stipulation to dismiss all claims and counterclaims with prejudice under Federal Rule of Civil Procedure 41(a)(1). Judge Gilstrap acknowledged and accepted the stipulation. The dismissal with prejudice is a permanent resolution — neither EMM Innovations nor Lark Technologies may reassert the same claims arising from this dispute. Each party was ordered to bear its own costs and attorneys’ fees, and all pending motions were denied as moot.
The 422-day duration before a joint dismissal is consistent with cases that reached at least an advanced stage of pre-trial negotiation, possibly including claim construction or settlement discussions. The mutual cost-bearing arrangement — rather than a fee award — suggests neither party achieved a clearly dominant litigation position. The specific terms of any underlying settlement, including licensing arrangements or financial consideration, are not disclosed in the public record.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1) dismissal with prejudice — a permanent, consensual end
A joint stipulation under Fed. R. Civ. P. 41(a)(1) allows parties to dismiss a case without court approval. When filed jointly and with prejudice, the dismissal operates as a final adjudication on the merits — neither party can re-litigate the same claims. The court’s role is limited to acknowledgment, as occurred here. This mechanism is commonly used to formalize a private settlement without disclosing its terms.
Rule 41(a)(1) — joint stipulationEMM Innovations is permanently barred from re-asserting these claims against Lark
By agreeing to dismiss with prejudice, EMM Innovations LLC surrenders any future right to bring the same patent infringement claims against Lark Technologies based on US10776756B2 and the Lark Suite. This is a meaningful concession for a patent assertion entity. However, the patent itself remains in force and may still be asserted against other defendants — the bar is party-specific, not patent-wide.
Patent survives — claim bar is defendant-specificLark Technologies achieves certainty — no future EMM suit on this patent
Lark Technologies secures a permanent resolution to this specific infringement threat. The with-prejudice dismissal means EMM cannot return to court on the same claims under US10776756B2 concerning the Lark Suite. The own-costs arrangement avoids any financial penalty on Lark’s side. Whether a broader licensing agreement was reached remains undisclosed, but Lark’s operational exposure from this litigation is fully extinguished.
Full claim extinguishment for LarkCollaboration software firms should note patent US10776756B2 remains enforceable
The dismissal resolves the Lark dispute but leaves US10776756B2 intact and enforceable. EMM Innovations may pursue other online collaboration platform vendors. Companies offering workflow, task management, or team productivity tools — particularly those with U.S. market exposure — should assess their freedom to operate against this patent’s claims. The E.D. Texas venue choice signals a continued appetite for asserting this patent aggressively.

Official order — verbatim text
The court’s order reflects a purely procedural acknowledgment of a jointly filed Rule 41(a)(1) stipulation — Judge Gilstrap made no findings on infringement, validity, or claim scope. The with-prejudice designation is the operative legal term: it forecloses any future action by EMM against Lark on these specific claims. The denial of all pending motions as moot confirms no substantive rulings on the merits were ever entered, leaving the patent’s enforceability and validity legally untested in this proceeding.
US10776756B2 — online collaboration and workflow management technology
US10776756B2, filed under application number US14/149904, covers technology in the online collaboration and workflow management space. The patent was asserted against Lark Technologies’ flagship Lark Suite — a platform combining messaging, video conferencing, document collaboration, and task management. The technical claims likely address methods or systems for coordinating work tasks, notifications, or data sharing within a collaborative software environment, consistent with the productivity tool category.
The strategic significance of this patent lies in the breadth of the collaboration software market. Platforms including enterprise messaging, project management, and unified communication tools represent a high-growth segment with significant U.S. revenue exposure. EMM Innovations’ decision to assert this patent against a well-funded international competitor suggests confidence in the patent’s claim scope. Any company developing or commercialising online collaboration features in the U.S. market should assess overlap with US10776756B2’s claims.
Should your team run an FTO analysis against US10776756B2?
If your company develops or sells online collaboration software, workflow automation tools, team productivity platforms, or unified communication suites with U.S. users, US10776756B2 warrants direct attention.

What this case signals for the collaboration software IP landscape
A with-prejudice dismissal in E.D. Texas after 422 days carries strategic weight beyond the parties involved.
US10776756B2 remains live — other collaboration platforms face exposure
The dismissal does not invalidate or limit US10776756B2. EMM Innovations retains full enforcement rights against third parties. Any company offering online collaboration, task management, or workflow tools with U.S. operations should treat this patent as an active risk and conduct a freedom-to-operate analysis before scaling product features.
E.D. Texas remains the venue of choice for NPE patent assertions
Judge Gilstrap’s docket in Marshall is consistently among the highest-volume patent courts in the U.S. EMM’s choice of this venue signals a deliberate litigation strategy. Defendants in future cases involving this patent or similar collaboration-tool IP should anticipate aggressive scheduling and limited discovery flexibility typical of this court.
EMM v Lark — key questions answered
The case was dismissed with prejudice on September 25, 2025, pursuant to a joint stipulation filed by both parties under Fed. R. Civ. P. 41(a)(1). Each party was ordered to bear its own costs and attorneys’ fees. No merits ruling was entered by Judge Gilstrap.
EMM Innovations asserted US10776756B2, filed under application number US14/149904, which covers technology in the online collaboration and workflow management space. The patent was alleged to be infringed by the Lark Suite of online collaboration tools developed and marketed by Lark Technologies Pte. Ltd.
A dismissal with prejudice bars EMM Innovations from re-filing the same infringement claims against Lark Technologies based on US10776756B2. However, the patent itself remains valid and enforceable. EMM retains the right to assert US10776756B2 against other parties — the preclusion effect is limited to the specific claims and defendant in this case.
The Eastern District of Texas, and specifically Judge Gilstrap’s docket in Marshall, is one of the most frequently chosen venues for patent assertion entity litigation due to its historically plaintiff-friendly procedures, experienced patent judiciary, and established case management practices. This venue selection is consistent with NPE litigation strategy in the U.S.
The case lasted 422 days from filing on July 30, 2024, to closure on September 25, 2025. This duration is longer than typical early-stage nuisance settlements and is consistent with cases that progressed through at least preliminary motions or claim construction preparation before the parties reached a resolution. The own-costs order and with-prejudice dismissal together suggest a negotiated exit rather than a clear victory for either side.
