Secure Communication Technologies v. Samsung — Dismissed With Prejudice After 407 Days

Secure Communication Technologies, LLC filed suit against Samsung Electronics in the Eastern District of Texas, asserting two patents covering wireless proximity and device-discovery technologies against Samsung’s Fast Pair, Nearby Share, Quick Share, and Find My Mobile features. The parties jointly stipulated to dismissal with prejudice after 407 days, with each side bearing its own costs — a structure consistent with a confidential settlement.

Case overview

Patent NPE targets Samsung’s device-connectivity ecosystem in E.D. Texas

On July 3, 2024, Secure Communication Technologies, LLC — a non-practising entity — filed suit against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the Eastern District of Texas (Case No. 2:24-cv-00484). The complaint asserted two patents, US11443344B2 and US11334918B2, against a broad swath of Samsung’s consumer device-connectivity features: Fast Pair, Nearby Share, Quick Share, Find My Mobile, and SmartThings Find, spanning Galaxy smartphones, the Galaxy Tab S9 series, and the Galaxy Book4 laptop line.

The case closed on August 14, 2025, via a Joint Stipulation of Dismissal filed under Rule 41(a)(1)(A)(ii), which the court accepted. All claims were dismissed with prejudice, meaning Secure Communication Technologies is permanently barred from asserting the same claims against Samsung in future litigation. The ‘each party bears its own costs’ provision is a standard feature of negotiated resolutions and suggests the parties reached terms without a formal fee-shifting determination.

The 407-day duration — spanning just over 13 months — indicates the case progressed through meaningful pre-trial activity before resolution, consistent with claim construction briefing or early discovery exchanges that may have informed the settlement calculus. The public record does not disclose financial terms, licence scope, or whether Samsung obtained a cross-licence. The breadth of accused products — covering Samsung’s entire proximity-pairing and device-finding stack — suggests the commercial stakes were substantial enough to warrant serious negotiation.

Dismissal terms

Dismissed with prejudice: what the joint stipulation means for both parties

Legal mechanism

Rule 41(a)(1)(A)(ii) — joint stipulation, no court merits ruling

A dismissal under Rule 41(a)(1)(A)(ii) is filed jointly by both parties and takes effect without requiring a judicial merits decision. The court’s role is purely administrative — it accepts and acknowledges the stipulation. ‘With prejudice’ means the plaintiff has permanently waived the right to refile these specific claims against Samsung. This mechanism is the standard vehicle for patent settlements where the parties wish to conclude litigation cleanly.

Procedural dismissal — no merits adjudicated
Plaintiff outcome

SCT cannot refile — rights extinguished against Samsung

With prejudice dismissal extinguishes Secure Communication Technologies’ ability to assert US11443344B2 or US11334918B2 against Samsung in any future action on the same accused features. If a financial settlement was reached — which the structure suggests — SCT would have received value in exchange for this permanent bar. SCT retains the patents and may continue to assert them against third parties, but Samsung is effectively licensed or released from further risk on these patents.

Permanent bar — Samsung-specific
Defendant outcome

Samsung resolves exposure across its full connectivity stack

Samsung’s dismissal with prejudice covers all accused products — Galaxy smartphones, tablets, and laptops, plus the Fast Pair, Nearby Share, Quick Share, Find My Mobile, and SmartThings Find feature set. The cost-neutrality clause (each party bears own fees) removes any ancillary financial exposure from attorneys’ fee motions. Samsung avoids any public claim construction ruling that could have been used against it in parallel or subsequent litigation involving the same patents.

Commercial implications

Wireless proximity patents remain viable against other OEMs

The with-prejudice dismissal resolves only the Samsung dispute. US11443344B2 and US11334918B2 remain in force and are fully enforceable against other device manufacturers, chip vendors, or software platforms implementing comparable proximity-pairing or device-discovery functionality. Competitors offering analogous Bluetooth pairing, UWB-based finding, or cross-device sharing features — including Apple, Google, and Android OEMs — remain potential targets. No claim construction positions were published that would narrow the patents’ scope.

Official verdict

Official order — verbatim text

“Before the Court is the Joint Stipulation of Dismissal Pursuant to Rule 41(a)(1)(A)(ii) (the “Stipulation”) filed by Secure Communication Technologies, LLC. (“Plaintiff”) and SAMSUNG ELECTRONICS CO., LTD. and SAMSUNG ELECTRONICS AMERICA, INC. (“Defendants”). (Dkt. No. 72.) In the Stipulation, the parties represent that the abovecaptioned case has been resolved and request dismissal of the above-captioned action WITH prejudice. (Id. at 1.) Having considered the Stipulation, the Court ACCEPTS AND ACKNOWLEDGES that all claims and causes of action asserted between Plaintiff and Defendant in the above-captioned case are DISMISSED WITH PREJUDICE. Each party is to bear its own costs, expenses, and attorneys’ fees. All pending requests for relief in the above-captioned case not explicitly granted herein are DENIED AS MOOT”
Source: PACER Docket, Case 2:24-cv-00484, Texas Eastern District Court

The court’s order reflects a purely administrative acceptance of the parties’ joint stipulation under Rule 41(a)(1)(A)(ii) — no merits findings were made regarding infringement, validity, or claim scope. The ‘with prejudice’ designation is the operative legal consequence: it functions as a final adjudication on the merits for res judicata purposes, permanently foreclosing re-litigation of these claims against Samsung. The ‘each party bears its own costs’ provision is standard in negotiated patent resolutions and forecloses any subsequent fee-shifting motion under 35 U.S.C. § 285.

US11443344B2 (application US17/366826) and US11334918B2 (application US15/271410) cover wireless proximity pairing and device-discovery technologies — the foundational layer enabling smartphones, tablets, and laptops to detect, authenticate, and connect with nearby devices or networks. These patents sit within a technically active space spanning Bluetooth Low Energy advertising, UWB-based ranging, and cross-platform device-finding protocols. The earlier application number for US11334918B2 (filed circa 2016) suggests a longer prosecution history and potentially broader priority claims.

The commercial significance of these patents lies in how deeply the accused features are embedded in Samsung’s product ecosystem — Fast Pair, Nearby Share, Quick Share, and SmartThings Find are not peripheral add-ons but core selling points of Samsung’s Galaxy devices. Any patent that credibly reads on these features carries leverage disproportionate to its technical specificity. For competing OEMs and platform developers building proximity-sharing or device-discovery capabilities on Android or proprietary stacks, these patents warrant monitoring given the absence of any limiting claim construction record.

Freedom to operate

Should your R&D team run an FTO against US11443344B2 and US11334918B2?

Any product team building Bluetooth proximity pairing, cross-device sharing, UWB-based finding, or device-discovery features — particularly on Android or in consumer IoT — should treat these patents as live FTO considerations. The Samsung dismissal is with prejudice and Samsung-specific; it creates no estoppel or narrowing of scope against third parties. The absence of a published Markman order means the claims have not been publicly construed, leaving maximum interpretive uncertainty for engineers and counsel assessing design-around options.

PatSnap Eureka’s FTO Search Agent can map the independent claims of US11443344B2 and US11334918B2 against your product’s feature set, surface the prosecution history for claim-scope signals, identify forward citations that may indicate how broadly the patents have been interpreted in related filings, and flag any post-grant proceedings that could affect enforceability.

Strategic implications

What this case signals for the wireless connectivity IP landscape

A broad NPE assertion against Samsung’s core device-pairing ecosystem — settled quietly — carries lessons for OEMs building on Bluetooth, UWB, and proximity-sharing standards.

E.D. Texas remains the venue of choice for connectivity NPE assertions

Filing in the Eastern District of Texas signals plaintiff intent to leverage the court’s patent-friendly docket and Marshall division infrastructure. Samsung deployed O’Melveny & Myers and local counsel Gillam & Smith — a team assembled for substantive defence, not a token appearance. Any OEM operating comparable device-discovery or proximity-pairing features should treat this filing pattern as a litigation-risk indicator.

Broad product-scope complaints create maximum settlement leverage

Secure Communication Technologies named Fast Pair, Nearby Share, Quick Share, Find My Mobile, and SmartThings Find across smartphones, tablets, and laptops in a single complaint. Bundling the entire connectivity stack into one action maximises the financial ceiling for negotiation. Companies in this space should audit whether their cross-device sharing, Bluetooth pairing, and UWB location features fall within the scope of these two patent families before a demand letter arrives.
