Nariste Networks v. Samsung: GPS Patent Suit Dismissed With Prejudice After 881 Days
Australian patent holder Nariste Networks Pty. Ltd. sued Samsung Electronics over USRE048206E, a reissue patent covering reduced power consumption in mobile GPS-based technologies. Filed in the Eastern District of Texas, the case ended when Nariste voluntarily dismissed all claims with prejudice — permanently extinguishing its right to refile the same allegations against Samsung.
A reissue GPS patent assertion ends permanently in E.D. Tex.
Nariste Networks Pty. Ltd., an Australian entity holding reissue patent USRE048206E, filed suit on 27 January 2023 in the Eastern District of Texas against Samsung Electronics Co., Ltd. and its U.S. subsidiary Samsung Electronics America, Inc. The complaint alleged infringement of patent claims covering reduced power consumption techniques in mobile GPS-based technologies — an area central to modern smartphone and wearable device operation.
After 881 days of litigation, Nariste filed a Corrected Notice of Dismissal specifying that the case be voluntarily dismissed with prejudice. The court accepted the notice under Rule 41(a)(1)(A)(i) and formally closed the case on 26 June 2025. Dismissal with prejudice is a final adjudication on the merits as to the dismissed claims, meaning Nariste cannot refile the same patent infringement allegations against Samsung in any federal court.
The nearly two-and-a-half year duration before dismissal suggests the parties engaged in substantial litigation activity — including likely claim construction and discovery — before Nariste elected to withdraw. The public record does not disclose whether a confidential settlement was reached, though a with-prejudice dismissal at this stage is consistent with either a negotiated resolution or a strategic decision that continued litigation was no longer viable.

Dismissed with prejudice: what the voluntary exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff-initiated dismissal with prejudice
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss an action by filing a notice before the opposing party serves an answer or motion for summary judgment — or, as here, by filing a notice that specifies dismissal with prejudice. A with-prejudice designation converts the voluntary exit into a final judgment on the merits, carrying full res judicata effect against Nariste for these claims against Samsung.
Rule 41 — final on the meritsNariste permanently barred from reasserting USRE048206E against Samsung
By specifying dismissal with prejudice, Nariste forfeited the ability to refile the same infringement claims against Samsung in any U.S. federal court. This is the most consequential form of voluntary dismissal for a patent holder. Whether Nariste received value in a confidential settlement, or concluded the litigation was no longer commercially viable, is not disclosed in the public record — but the permanent bar is unambiguous.
No refile — res judicata appliesSamsung exits with a permanent shield on these claims
Samsung Electronics and its U.S. subsidiary obtained the strongest possible dismissal outcome short of a court judgment in their favour. The with-prejudice designation means Samsung cannot be sued again by Nariste on the same patent claims arising from the same products. Samsung’s legal team — fielding counsel from O’Melveny & Myers and Gillam & Smith — invested significant resources over 881 days, suggesting the defence was vigorously contested before Nariste withdrew.
Full claim bar for SamsungGPS power-efficiency patents remain an active litigation risk for device makers
Although this specific action is extinguished, USRE048206E remains an enforceable patent against other smartphone, wearable, and IoT device manufacturers. Mobile GPS power-reduction technology is broadly embedded in consumer electronics, and reissue patents that survive this long in litigation typically suggest non-trivial claim scope. Competitors and component suppliers in this space should monitor Nariste’s patent portfolio for continued assertion activity.

Official order — verbatim text
The court’s order tracks the precise language of Nariste’s Corrected Notice — accepting dismissal ‘with prejudice’ and denying all remaining relief as moot. The with-prejudice designation is legally significant: it operates as a final adjudication on the merits, barring Nariste from relitigating the same claims against Samsung under the doctrine of res judicata. The court’s invocation of Rule 41(a)(1)(A)(i) confirms this was a plaintiff-initiated exit rather than a court-ordered termination, preserving the voluntary character of the dismissal while producing the same preclusive effect as a final judgment.
USRE048206E — reduced power consumption in mobile GPS-based technologies
USRE048206E is a United States reissue patent, meaning the original patent was corrected through the USPTO’s reissue process after grant — a mechanism available when a patent is deemed wholly or partly inoperative due to a defective specification or claims. The ‘RE’ designation signals that the claims have been subject to additional USPTO scrutiny beyond the original examination, which may result in broadened or narrowed claim scope relative to the original grant. The underlying application number US15/376627 provides a reference point for the original filing lineage. The subject matter — reducing power consumption in mobile GPS-based technologies — sits at the intersection of location services, RF chipset design, and battery management, which are core functions in virtually every modern smartphone, wearable, and connected vehicle system.
From a competitive standpoint, GPS power efficiency patents carry broad relevance across the consumer electronics supply chain. Any device that integrates location services — from flagship smartphones to fitness trackers and automotive navigation units — potentially falls within the technical scope of claims directed at power-reduction methods. Samsung’s decision to deploy a large defence team over nearly two and a half years, rather than seek early dismissal or inter partes review, suggests the claims were not easily designed around or invalidated on the face of the record. This makes USRE048206E a material watch-item for other OEMs and chipset vendors operating in the GPS and location-technology space.
Should your GPS or location-tech product be cleared against USRE048206E?
Any product team developing devices that incorporate GPS, GNSS, or location-based services with active power-management features should assess exposure to USRE048206E. This includes smartphone OEMs, wearable device manufacturers, IoT platform providers, and automotive navigation system suppliers. The fact that Nariste pursued Samsung — a defendant with enormous litigation resources — for nearly 881 days before settling or withdrawing suggests the patent holder views these claims as commercially meaningful and enforceable across the industry.
PatSnap Eureka’s FTO Search Agent can map the claims of USRE048206E against your product’s technical architecture, identify prior art that could support an invalidity argument, and surface related patent families that Nariste or similar licensing entities may deploy in follow-on assertions. Running an FTO at the design phase is materially cheaper than litigating in the Eastern District of Texas. Eureka also enables continuous portfolio monitoring so that any new Nariste filings against other defendants trigger an immediate alert for your IP team.

What this case signals for the mobile GPS and patent licensing IP landscape
An 881-day Eastern District of Texas campaign ending in a with-prejudice exit carries distinct signals for GPS technology IP strategy.
Reissue patents in E.D. Tex. command serious defence resources
Samsung deployed 13 defence counsel across O’Melveny & Myers, Gillam & Smith, and Potter Minton — a formation typical of high-stakes Eastern District patent matters. Companies operating in the mobile GPS and location-services space should treat reissue patent assertions in this venue as requiring full litigation readiness from day one.
With-prejudice dismissal at the 881-day mark suggests a negotiated resolution
Voluntary dismissals with prejudice after extended litigation — well past early motion practice — are statistically more likely to reflect a confidential settlement than a unilateral abandonment. Parties monitoring similar GPS licensing disputes should treat this outcome as consistent with a paid resolution rather than a free walk for either side.
Nariste v Samsung — key questions answered
Dismissal with prejudice in this case means Nariste Networks permanently relinquished its right to sue Samsung Electronics and Samsung Electronics America on the same infringement claims under USRE048206E. It operates as a final judgment on the merits, triggering res judicata. Nariste cannot refile these claims in any U.S. federal court against Samsung.
Nariste Networks asserted USRE048206E, a United States reissue patent with underlying application number US15/376627. The patent covers reduced power consumption in mobile GPS-based technologies — methods relevant to GPS and location-services functionality in smartphones, wearables, and connected devices.
The public record does not disclose settlement terms. The case was voluntarily dismissed with prejudice by Nariste under Rule 41(a)(1)(A)(i) after 881 days of litigation. A with-prejudice dismissal after extended litigation is statistically consistent with a confidential settlement, though this cannot be confirmed from the docket alone.
The Eastern District of Texas is a historically popular venue for patent infringement suits due to its plaintiff-friendly procedural reputation, experienced patent judiciary, and established case management procedures. Nariste, an Australian entity, chose this venue — a common strategy for non-practising entities and foreign patent holders asserting U.S. patents against major technology companies.
A reissue patent is issued when the original patent is corrected through USPTO reexamination because it was wholly or partly inoperative or invalid due to a defective specification, drawing, or claims. The ‘RE’ prefix on USRE048206E indicates the claims underwent additional USPTO review post-grant. This may mean claims were broadened or narrowed, and the reissue process adds a layer of prosecution history that is critical for any claim construction or invalidity analysis.
