SmartWatch MobileConcepts v. T-Mobile — Dismissed With Prejudice in 252 Days
SmartWatch MobileConcepts, LLC filed a patent infringement action against T-Mobile in the Western District of Texas, asserting US10362480B2 — a patent covering wearable device user access to secured electronics systems. The parties filed a joint stipulation of dismissal with prejudice on January 30, 2024, closing the case in under nine months.
Wearable device authentication suit against T-Mobile ends in 252 days
SmartWatch MobileConcepts, LLC filed suit against T-Mobile on May 24, 2023 in the Western District of Texas (Case No. 6:23-cv-00400), asserting infringement of US10362480B2. The patent covers systems, methods and apparatuses for enabling wearable device user access to secured electronics systems — a technology area directly relevant to connected device and smartwatch product ecosystems offered through major carriers like T-Mobile.
The case closed on January 31, 2024, when the court granted the parties’ joint stipulation of dismissal with prejudice filed under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Dismissal with prejudice is final and operates as a judgment on the merits, permanently barring SmartWatch MobileConcepts from reasserting the same claims against T-Mobile. Each party was ordered to bear its own attorney fees and costs, suggesting no financial settlement terms were made public.
At 252 days, the resolution is notably fast relative to typical district court patent litigation timelines, suggesting the parties reached an understanding well before any claim construction or substantive merits proceedings. The absence of docketed claim construction activity and the mutual cost-bearing arrangement are consistent with either a private licensing resolution or a decision by plaintiff to withdraw — the public record does not confirm which. Ramey LLP, plaintiff’s counsel, is a prolific patent assertion firm in W.D. Tex., a pattern worth noting for defendants monitoring similar actions.

Joint stipulation of dismissal with prejudice under Rule 41(a)(1)(A)(ii)
Rule 41(a)(1)(A)(ii): self-executing dismissal by stipulation
Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), all parties who have appeared may jointly stipulate to dismiss an action without requiring court approval. As the Fifth Circuit confirmed in Yesh Music v. Lakewood Church, such dismissals are effective automatically upon filing. The court’s order here is ministerial — confirming closure — rather than an exercise of judicial discretion.
No judicial merits ruling requiredWith prejudice means permanent — no second bite at T-Mobile
Dismissal with prejudice functions as a final adjudication on the merits. SmartWatch MobileConcepts is permanently barred from filing a new action against T-Mobile asserting the same claims under US10362480B2. This is the key distinction from a without-prejudice dismissal, which would preserve the right to refile. The with-prejudice designation here benefits T-Mobile with lasting certainty.
Bars refiling against T-MobileEach party bears own costs — no fee-shifting order
The court ordered each party to bear its own attorney fees and costs. Under U.S. patent law, fee-shifting under 35 U.S.C. § 285 requires a finding of an ‘exceptional case.’ No such finding was made here. The mutual cost-bearing arrangement is the default outcome in agreed dismissals and does not indicate either party’s relative legal strength or any underlying financial terms.
No § 285 exceptional case findingAll pending motions denied as moot on dismissal
The court’s order denied all pending motions as moot upon granting the stipulated dismissal. This is standard practice when a case resolves before substantive rulings. It means no claim construction order, validity ruling, or infringement analysis was issued — the patent’s scope and validity remain judicially untested in this proceeding, preserving uncertainty for future assertion against other parties.

Stipulation of dismissal — official text
The court’s order grants a joint stipulation under Rule 41(a)(1)(A)(ii), which is self-executing and requires no merits analysis. The with-prejudice designation is the operative legal term: it permanently extinguishes SmartWatch MobileConcepts’ right to sue T-Mobile under US10362480B2. No damages, royalty rates, or licensing terms are disclosed. The moot denial of pending motions confirms no substantive patent analysis was conducted, leaving the patent’s validity and claim scope fully intact for assertion in future proceedings against other parties.
US10362480B2 — Wearable Device Authentication & Secured Electronics Access
US10362480B2, filed under application number US15/234565, protects systems, methods and apparatuses for enabling wearable device users to access secured electronics systems. The patent sits at the intersection of wearable computing and authentication technology — covering how a wearable such as a smartwatch can serve as an authentication or access credential for a paired or proximate secured electronic device. This is a technically broad claim space that encompasses smartwatch-to-smartphone unlock, wearable proximity authentication, and related credential-relay architectures.
For wireless carriers and device ecosystem participants, this patent class is strategically significant. Carriers like T-Mobile sell and provision both wearables and secured smartphones, potentially placing them within the scope of method claims covering device pairing and access enablement. The patent’s survival without any IPR or validity challenge in this proceeding means it retains presumptive validity. Competitors and supply chain participants in the wearable ecosystem — OEMs, OS platform vendors, accessory makers — should treat this patent as an active assertion risk until its claims are narrowed or invalidated.
Should your wearable product team run an FTO against US10362480B2?
Any company developing or commercialising wearable devices that interact with secured electronics — including smartwatches with unlock functionality, fitness bands with NFC payment access, or wearable-based enterprise authentication solutions — should conduct a freedom-to-operate review against US10362480B2. The patent’s claim language around ‘enabling wearable device user access to secured electronics systems’ is broad enough to warrant scrutiny before product launch or carrier partnership agreements.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map their product architecture against the claims of US10362480B2, identify design-around opportunities, and surface relevant prior art that could support an IPR petition or invalidity argument.

SmartWatch MobileConcepts retains full rights to assert US10362480B2 against other defendants — including device OEMs, other carriers, and platform providers. Companies with wearable authentication or secured device access products should evaluate their exposure before receiving a demand letter.
Ramey LLP’s W.D. Tex. filing pattern signals systematic assertion strategy
Ramey LLP is among the most active patent assertion firms in the Western District of Texas. Their involvement as plaintiff’s counsel is consistent with a volume-based licensing strategy targeting multiple defendants sequentially. Early resolution — as seen here — often reflects nuisance-value settlements rather than substantive merits engagement. Monitoring Ramey LLP dockets for US10362480B2 is advisable.
SmartWatch v T-Mobile — key questions answered
SmartWatch MobileConcepts, LLC filed a patent infringement suit against T-Mobile in the Western District of Texas on May 24, 2023, asserting US10362480B2. The parties filed a joint stipulation of dismissal with prejudice on January 30, 2024, and the court closed the case on January 31, 2024 — 252 days after filing. Each party bore its own attorney fees and costs.
Dismissal with prejudice is a final adjudication on the merits. It permanently bars SmartWatch MobileConcepts from filing a new lawsuit against T-Mobile asserting the same claims under US10362480B2. The company retains full rights to assert the patent against other defendants not party to this stipulation.
US10362480B2 covers systems, methods and apparatuses for enabling wearable device user access to secured electronics systems. T-Mobile, as a major U.S. wireless carrier that sells and provisions both wearable devices and smartphones, was likely targeted as a potential direct or indirect infringer of method or system claims relating to wearable device authentication and access enablement.
The public record does not disclose any settlement agreement. The parties filed a joint stipulation of dismissal with prejudice, and the court ordered each side to bear its own costs. Whether a confidential licensing arrangement or financial settlement underpins the stipulation is not determinable from the available docket.
Yes. The with-prejudice dismissal applies only to claims against T-Mobile. SmartWatch MobileConcepts retains all rights to assert US10362480B2 against other parties. No IPR or invalidity ruling was issued in this case, so the patent’s validity is legally presumed intact. Other carriers, device OEMs, and wearable ecosystem companies remain potential targets.
