Agis Software v. TCL Technology: Infringement Suit Dismissed With Prejudice After 460 Days
Agis Software Development LLC filed suit against TCL Technology Group and three affiliated entities in the Eastern District of Texas, asserting five patents covering forced-alert and ad hoc network communication methods. The case was voluntarily dismissed with prejudice by Agis after 460 days, with each party bearing its own costs and fees.
Agis Drops Five-Patent Mobile Alert Suit Against TCL With Prejudice
On 18 November 2022, Agis Software Development LLC filed a patent infringement action in the Eastern District of Texas before Chief Judge Rodney Gilstrap. Agis named TCL Technology Group Corporation as lead defendant alongside three affiliates — TCT Mobile (US) Inc., TCL Electronics Holdings Limited, and TCL Communication Technology Holdings Limited — asserting infringement of five US patents directed to forced-alert interactive communications and ad hoc password-protected digital and voice networks.
On 21 February 2024, Agis filed a Notice of Dismissal with Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court accepted the notice and formally dismissed all claims with prejudice. Crucially, the order specifies that each party bears its own costs, expenses, and attorneys’ fees, meaning no prevailing-party fee award was made. Dismissal with prejudice extinguishes Agis’s ability to re-assert the same claims against the same TCL entities in federal court.
The 460-day duration before voluntary dismissal with prejudice — without reaching claim construction, trial, or any disclosed settlement — is consistent with a pre-trial resolution, potentially a licensing agreement, a cross-licence, or a strategic decision by Agis to withdraw. The public record does not disclose the commercial terms, if any, that preceded the dismissal, and the mutual cost-bearing order neither confirms nor rules out a confidential settlement.

Dismissed with prejudice: what the Rule 41 order means for both sides
Rule 41(a)(1)(A)(i) dismissal with prejudice explained
Under FRCP 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss before the defendant serves an answer or motion for summary judgment. Filing ‘with prejudice’ converts what would otherwise be a cost-free exit into a final adjudication on the merits for preclusion purposes. Agis cannot re-file the same claims against these defendants in any federal court — the dismissal has res judicata effect.
Permanent bar on re-filingAgis permanently surrenders these claims against TCL entities
By choosing dismissal with prejudice, Agis foreclosed any future infringement action on these five patents against TCL Technology Group, TCT Mobile (US), TCL Electronics Holdings, and TCL Communication Technology Holdings. Whether Agis received commercial consideration — a licence, cross-licence, or lump-sum payment — is not disclosed in the public record. The mutual cost-bearing clause suggests neither side claimed outright victory.
Claims permanently extinguishedTCL group secures permanent dismissal at no disclosed cost
All four TCL entities exit the litigation with a with-prejudice dismissal that bars re-assertion of these specific claims. The absence of a fee-shift order under 35 U.S.C. § 285 means the case was not adjudicated as ‘exceptional,’ which is consistent with an early resolution. TCL retains exposure to these patents from other parties but not from Agis under this action.
No fee-shift; no exceptional case findingForced-alert and ad hoc network patents remain live against other defendants
The five asserted patents — covering forced interactive alert delivery and ad hoc password-protected voice/data networks — survive this dismissal and remain enforceable. Agis has a history of asserting overlapping portfolios against multiple defendants serially. Other mobile device manufacturers and OEMs operating in the same technology space should treat these patents as active enforcement risk and consider FTO analysis before this outcome is misconstrued as a portfolio retirement.

Official order — verbatim text
The court’s order accepts Agis’s Rule 41(a)(1)(A)(i) notice without substantive merits analysis — this is a plaintiff-initiated exit, not a judicial finding on validity or infringement. The explicit ‘with prejudice’ designation is the operative term: it binds Agis to the dismissal as a final judgment for preclusion purposes against these defendants. The denial of all pending relief as moot and the mutual cost-bearing clause collectively indicate no exceptional case finding was made or sought, which preserves Agis’s reputational standing to assert the same patents elsewhere.
US9445251B2 — Forced alerts for interactive remote communications
The five asserted patents — US9445251B2, US8213970B2, US9467838B2, US9749829B2, and US9820123B2 — span application dates from 2008 through 2016, covering a technology window that encompasses the rise of smartphone push-notification infrastructure and mobile group communications. The patents describe methods for delivering forced, interactive alerts to remote devices and establishing ad hoc password-protected voice and data networks — claim territory that intersects with modern emergency alert systems, group messaging protocols, and managed push-notification frameworks.
For mobile OEMs, platform vendors, and enterprise communications software developers, this patent cluster represents material enforcement risk. Agis has previously asserted overlapping portfolios against major Android device manufacturers. The breadth of the method claims — particularly around forced delivery and ad hoc network establishment — means that products shipping standard Android notification stacks, MVNO services, or peer-to-peer encrypted communications could fall within arguable claim scope. Competitor intelligence and FTO clearance against this family are advisable before launching products in these categories.
Should your product team run an FTO against US9445251B2 and the Agis alert patent family?
Any company shipping mobile devices, notification management software, emergency alert integrations, or ad hoc voice/data networking features should assess exposure to this five-patent cluster. The dismissal against TCL does not constitute a finding of non-infringement — it simply removes TCL from Agis’s current target list. Agis’s enforcement history suggests serial assertion against successive mobile OEMs, making early FTO clearance commercially valuable for any company in this product space.

What this case signals for the mobile communications patent enforcement landscape
A with-prejudice exit from E.D. Texas after 460 days raises questions about Agis’s broader assertion strategy and TCL’s defensive posture.
With-prejudice dismissal does not retire the patents — monitor for new targets
The five asserted patents remain in force. Agis’s decision to dismiss with prejudice against TCL specifically — rather than allow the patents to be tested at claim construction — is consistent with a licensing resolution or a strategic pivot. Companies in mobile communications, alert delivery, and ad hoc networking should monitor Agis’s docket for new filings asserting the same portfolio.
E.D. Texas remains a preferred venue for mobile patent assertions — prepare early
Chief Judge Gilstrap’s docket moves quickly. The absence of any docketed claim construction order in this case suggests resolution occurred before the Markman stage. Defendants in similar suits should engage claim construction strategy and prior art analysis early to create leverage for pre-Markman resolution on commercially acceptable terms.
Agis v TCL — key questions answered
Agis Software Development LLC filed a patent infringement suit against TCL Technology Group Corp. and three affiliated entities in the Eastern District of Texas on 18 November 2022, asserting five patents on forced-alert communications and ad hoc networks. Agis voluntarily dismissed the case with prejudice on 21 February 2024 under FRCP 41(a)(1)(A)(i), with each party bearing its own costs and fees.
Agis asserted five US patents: US9445251B2, US8213970B2, US9467838B2, US9749829B2, and US9820123B2. These patents cover methods for delivering forced interactive alerts for remote communications and establishing ad hoc password-protected digital and voice networks — technology relevant to smartphone notification systems and mobile group communication platforms.
Dismissal with prejudice under Rule 41(a)(1)(A)(i) operates as a final adjudication on the merits for res judicata purposes. Agis is permanently barred from re-filing the same claims against TCL Technology Group, TCT Mobile (US), TCL Electronics Holdings, and TCL Communication Technology Holdings in any federal court. The five asserted patents remain enforceable against other parties.
The public record does not disclose settlement terms. The with-prejudice dismissal and mutual cost-bearing clause are consistent with a confidential resolution — potentially a licence, cross-licence, or lump-sum payment — but neither the court order nor any publicly filed document confirms or quantifies commercial consideration. The absence of a § 285 exceptional case finding suggests no party sought a fee award.
Yes. US9445251B2, US8213970B2, US9467838B2, US9749829B2, and US9820123B2 remain in force. Dismissal with prejudice against TCL extinguishes claims only as between Agis and the named TCL entities. Other mobile device manufacturers, notification platform vendors, and ad hoc networking software developers remain potentially exposed to assertion of these patents by Agis or any future assignee.
