Agis Software Development v. OnePlus Technology — Dismissed With Prejudice After 416 Days
Agis Software Development LLC filed a five-patent infringement action against Chinese smartphone maker OnePlus Technology in the Eastern District of Texas, asserting patents covering forced-alert interactive communications and ad hoc password-protected digital networks. The case closed on 8 January 2024 when Agis voluntarily dismissed all claims with prejudice under FRCP 41(a)(1)(A)(i), with each party bearing its own costs.
Five-patent mobile comms case ends in plaintiff-initiated dismissal
On 18 November 2022, Agis Software Development LLC filed suit against OnePlus Technology (Shenzhen) Co., Ltd. in the Eastern District of Texas (Case No. 2:22-cv-00446), presided over by Chief Judge Rodney Gilstrap. Agis asserted five US patents — US9445251B2, US8213970B2, US9467838B2, US9749829B2, and US9820123B2 — directed at methods for forced interactive alerts and ad hoc password-protected digital and voice networks, technologies core to modern smartphone communication stacks.
The case closed on 8 January 2024 when Agis filed a Notice of Dismissal With Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Judge Gilstrap accepted and acknowledged the dismissal, extinguishing all claims and causes of action. Crucially, the dismissal was with prejudice, meaning Agis is permanently barred from reasserting these specific claims against OnePlus. The court ordered each party to bear its own costs, expenses, and attorneys’ fees, suggesting no negotiated cost-shifting took place.
At 416 days, the case resolved before reaching claim construction or trial — a pattern consistent with either a confidential settlement or a strategic withdrawal. Because FRCP 41(a)(1)(A)(i) requires no court order and no defendant consent when filed before an answer or summary judgment motion, the public record is silent on whether any licensing arrangement accompanied the dismissal. The ‘with prejudice’ designation is unusual for a pure walk-away and may suggest a collateral agreement was reached privately.
Filing to dismissal in 416 days
416 days — resolved well within median E.D. Texas patent trial timeline
Plaintiff dismissed all five patent claims with prejudice — no costs awarded
FRCP 41(a)(1)(A)(i) — unilateral dismissal, no court order needed
Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order simply by filing a notice, provided the defendant has not yet served an answer or a motion for summary judgment. This is the earliest and least burdensome exit mechanism available. Its use here suggests the parties moved quickly and the defendant had not yet formally answered, which is consistent with a pre-answer resolution.
Voluntary plaintiff dismissalWith prejudice bars Agis from refiling these exact claims against OnePlus
A dismissal with prejudice operates as a final adjudication on the merits, permanently extinguishing Agis’s right to reassert the same patent claims against OnePlus. This is a significant concession by the plaintiff. Whether it reflects a negotiated settlement, a licensing resolution, or a purely strategic retreat is not determinable from the public docket — but the choice of ‘with prejudice’ over ‘without prejudice’ is a material signal.
Claims permanently extinguishedEach party bears own costs — no fee-shifting under § 285
The court ordered each side to bear its own costs, expenses, and attorneys’ fees. Under 35 U.S.C. § 285, courts may award fees in ‘exceptional cases,’ but that threshold was never reached here. The mutual cost-bearing order is standard for early voluntary dismissals and does not indicate any finding of bad faith or exceptional conduct by either party. OnePlus escapes without a cost recovery despite being the named defendant.
No § 285 fee awardConfidential licensing deal cannot be ruled out
Agis Software Development is an active patent assertion entity with a documented history of multiparty litigation campaigns involving these same mobile communication patents. A with-prejudice dismissal at this early stage — before claim construction — is consistent with a confidential licensing agreement resolving the dispute. However, no settlement terms appear in the public record, and this analysis is necessarily speculative based on observable litigation patterns.

Stipulation of dismissal — official text
The court’s order accepts a plaintiff-initiated FRCP 41(a)(1)(A)(i) dismissal, which requires no judicial finding on the merits. The with-prejudice designation — voluntarily selected by Agis — is the operative legal consequence: it forecloses any future refiling of these patent claims against OnePlus in any US court. The mutual cost-bearing directive confirms no exceptional-case finding was made. For OnePlus, the case closes without any admission of liability or invalidity ruling on any of the five asserted patents.
US9445251B2 and 4 Related Patents — Mobile Alert & Ad Hoc Network Methods
The five asserted patents span two core technology clusters. The first, anchored by US9445251B2 (App. No. 14/633804), covers methods for delivering forced alerts in interactive remote communications — effectively mandatory-acknowledgement notification systems on mobile devices. The second cluster, led by US8213970B2 (App. No. 12/324122), protects methods for establishing ad hoc, password-protected digital and voice networks. These application numbers suggest filing dates in the mid-2000s to mid-2010s, placing these inventions in the formative era of smartphone-centric push notification and peer-to-peer network architectures.
For smartphone OEMs, these patents sit at a commercially sensitive intersection: push notification infrastructure and device-level network formation are foundational to modern handset software stacks, including features like emergency alerts, group messaging, and local Wi-Fi direct networking. Agis’s willingness to assert all five patents simultaneously against OnePlus — and its broader multiparty campaign — suggests the portfolio is being actively monetised. Any manufacturer shipping devices with similar alert or ad hoc networking functionality into the US market faces non-trivial exposure if these claims have not been licensed or design-arounded.
Should your product team run an FTO against US9445251B2 and its family?
If your company manufactures, imports, or sells smartphones, tablets, or IoT devices with push alert functionality or ad hoc network formation capabilities in the US market, these five Agis patents warrant a freedom-to-operate review. The Eastern District of Texas filing history and the with-prejudice resolution pattern suggest Agis is actively licensing this portfolio. A proactive FTO analysis can identify whether your specific product implementation falls within the asserted claim scope — and whether design-around options exist before a demand letter arrives.
PatSnap Eureka’s FTO Search Agent can map each independent claim of US9445251B2, US8213970B2, US9467838B2, US9749829B2, and US9820123B2 against your product’s technical specification, surface prior art that may support invalidity arguments, and set up claim-change monitoring alerts so you are notified if any continuation or divisional in the Agis family publishes with amended scope.

What this case signals for the mobile communications IP landscape
Agis’s five-patent campaign against OnePlus reflects ongoing pressure on smartphone OEMs from alert and network-method patent portfolios.
E.D. Texas remains the preferred venue for mobile patent campaigns
Filing before Judge Gilstrap in Marshall, Texas is a deliberate strategic choice. The Eastern District of Texas has historically high plaintiff win rates in patent cases and favourable scheduling orders. Smartphone OEMs operating in the US market should treat any Agis filing in this district as a credible enforcement threat requiring immediate response planning.
A with-prejudice exit by plaintiff suggests the dispute did not simply evaporate
Pure walk-aways typically result in without-prejudice dismissals that preserve optionality. The with-prejudice designation here — voluntarily chosen by Agis — suggests something of value changed hands or was conceded. Companies facing similar claims from Agis should note this pattern when assessing their own risk exposure and negotiation leverage.
Agis v OnePlus — key questions answered
Agis Software Development LLC filed a five-patent infringement action against OnePlus Technology (Shenzhen) in the Eastern District of Texas on 18 November 2022. The case was dismissed with prejudice on 8 January 2024 after Agis filed a voluntary notice of dismissal under FRCP 41(a)(1)(A)(i). Each party was ordered to bear its own costs.
Agis asserted five US patents: US9445251B2, US8213970B2, US9467838B2, US9749829B2, and US9820123B2. The patents cover methods for forced interactive alerts in remote communications and methods for establishing ad hoc password-protected digital and voice networks — technologies relevant to smartphone push notification and local networking features.
Dismissal with prejudice means Agis permanently waived its right to refile the same patent infringement claims against OnePlus in any US court. It operates as a final adjudication on the merits without a trial. The voluntary choice of with-prejudice — rather than without-prejudice — is notable and may suggest a collateral resolution such as a licensing agreement, though no such terms appear in the public record.
Agis was represented by Fabricant LLP and Truelove Law Firm, with attorneys including Alfred Ross Fabricant, Peter Lambrianakos, Vincent J. Rubino III, Enrique Iturralde, Justin Truelove, and Justine Park. OnePlus was represented by K&L Gates LLP (Seattle office), with Theodore J. Angelis as lead counsel.
No settlement is disclosed in the public court record. The case closed via a plaintiff-initiated voluntary dismissal with prejudice under FRCP 41(a)(1)(A)(i). The with-prejudice designation and early resolution before claim construction are consistent with a private licensing arrangement, but this cannot be confirmed from publicly available documents.
