Aperçu du dossier
In a case that drew significant attention from mobile technology IP circles, AGIS Software Development LLC’s patent infringement action against T-Mobile USA, Inc. concluded on March 11, 2024, with a dismissal with prejudice — a resolution that arrived after three years of litigation in one of the nation’s most active patent venues. Filed in the Eastern District of Texas before Chief Judge Rodney Gilstrap, the case centered on six patents covering location-sharing and mobile communications technology, with accused products including T-Mobile’s FamilyWhere, FamilyMode, and WhatsApp Messenger applications.
The joint stipulation of dismissal, combined with a parallel settlement between AGIS and third-party intervenor Smith Micro Software, signals the complex, multi-party dynamics that frequently define location-technology patent infringement litigation. For patent attorneys, in-house IP counsel, and R&D teams operating in mobile services, this case offers instructive lessons about assertion strategy, third-party interventions, and the negotiated resolution of technically intricate patent disputes.
Les parties
⚖️ Demandeur
A non-practicing entity (NPE) focused on asserting patents related to mobile location-sharing and communications technology. AGIS has maintained an active litigation posture across multiple venues.
🛡️ Défendeur
Among the largest wireless carriers in the United States, offering a broad ecosystem of consumer services — including family location-tracking products directly implicated in this suit.
🤝 Third-Party Intervenor
Technology provider whose software underlies certain T-Mobile services at issue, reflecting their direct stake in the outcome.
Brevets en cause
Six patents were asserted, spanning mobile location-sharing and push-to-talk communications:
- • US7031728B2 – Early mobile communications coordination
- • US7630724B2 – Location-based mobile device tracking
- • US9408055B2 – Advanced location-sharing functionality
- • US9445251B2 – Mobile device location services
- • US9467838B2 – Location-sharing system architectures
- • US9749829B2 – Mobile network location management
These patents collectively describe foundational systems enabling real-time location sharing among mobile users — technology embedded in consumer-facing family safety and messaging products.

Le verdict et l'analyse juridique
Résultat
On March 11, 2024, Chief Judge Gilstrap granted the Joint Notice of Stipulation and Motion to Dismiss With Prejudice (Dkt. No. 181), filed jointly by AGIS, T-Mobile, and Smith Micro. The dismissal with prejudice covers all claims and causes of action asserted by AGIS against T-Mobile relating to the FamilyWhere and FamilyMode products and services. Each party agreed to bear its own costs and attorneys’ fees. No damages figure was publicly disclosed, and the specific financial terms of the AGIS-Smith Micro settlement remain confidential.
Principales questions juridiques
The case was initiated as a straightforward infringement action — AGIS alleging that T-Mobile’s accused products practiced the claims of its six location-technology patents without authorization. The involvement of Smith Micro as a third-party intervenor added complexity: when the core technology in accused products is supplied by a vendor rather than developed in-house, both the carrier-defendant and the technology provider may have aligned or competing interests in the litigation’s outcome.
Smith Micro’s Motion to Stay (Dkt. No. 114) suggests the intervenor sought to pause proceedings — potentially while pursuing inter partes review (IPR) or another challenge mechanism — before agreeing to settle directly with AGIS. This procedural maneuver is a common defense tactic: intervene, seek a stay pending PTAB review, and use that leverage to negotiate a settlement on more favorable terms.
The dismissal with prejudice, while not an adjudication on the merits, extinguishes AGIS’s ability to re-assert these specific claims against T-Mobile’s FamilyWhere and FamilyMode products — a meaningful concession from AGIS, suggesting the settlement provided sufficient value to warrant finality.

Six U.S. patents were asserted: US7031728B2, US7630724B2, US9408055B2, US9445251B2, US9467838B2, and US9749829B2 — all directed to mobile location-sharing and communications technology.
The parties filed a joint stipulation under Fed. R. Civ. P. 41(a)(2), resolving all claims related to T-Mobile’s FamilyWhere and FamilyMode products. A concurrent AGIS-Smith Micro settlement addressed the intervenor’s claims.
The settlement reinforces that Non-Practicing Entity (NPE) assertions in mobile location technology frequently resolve through negotiation rather than adjudication, leaving patent validity and infringement questions unanswered — and the patents available for future assertions against other parties.
A Non-Practicing Entity (NPE), sometimes referred to as a ‘patent troll,’ is a company or individual that holds patents but does not manufacture products or offer services based on those patents. Instead, NPEs primarily derive revenue by asserting their patents against alleged infringers through litigation or licensing.
