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.
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.

Dismissed with prejudice: what the joint stipulation means for both parties
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 adjudicatedSCT 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-specificSamsung 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.
Full product stack releasedWireless 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 order — verbatim text
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 & US11334918B2 — Wireless Proximity Pairing and Device Discovery
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.
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.

Portfolio viewWhat 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.
US11443344B2 and US11334918B2 — forward citation risk for non-Samsung OEMs
No claim construction order issued in this case, meaning the patents’ scope was never publicly narrowed. Entities implementing comparable proximity-pairing or device-finding protocols — particularly those relying on BLE advertising or UWB ranging — face the highest residual risk. A freedom-to-operate analysis anchored to the prosecution history of these two patents is advisable before launching competing features.
The 407-day resolution window suggests a structured licence, not a nuisance settlement
Cases that settle in under 90 days typically reflect nuisance-value payments. A 407-day timeline — reaching through early Markman territory — suggests both parties invested substantially in the merits before agreeing to terms. This is consistent with a structured royalty arrangement or a lump-sum licence of meaningful value, and implies SCT viewed its patents as commercially credible after Samsung’s legal team had reviewed them.
SECURE v Samsung — key questions answered
The case was dismissed with prejudice. The Joint Stipulation of Dismissal filed under Rule 41(a)(1)(A)(ii) and accepted by the Eastern District of Texas court on August 14, 2025, explicitly states all claims are dismissed with prejudice, permanently barring Secure Communication Technologies from refiling the same claims against Samsung.
The complaint accused Samsung’s Fast Pair, Nearby Share, Quick Share, Find My Mobile, and SmartThings Find features across multiple product lines, including Galaxy S24 and Z4 series smartphones, Galaxy Tab S9 series tablets, and Galaxy Book4 series laptops.
Two patents were asserted: US11443344B2 (application no. US17/366826) and US11334918B2 (application no. US15/271410). Both cover wireless proximity pairing and device-discovery communication technologies.
Yes. A with-prejudice dismissal functions as a final adjudication on the merits for res judicata purposes, meaning Secure Communication Technologies cannot reassert US11443344B2 or US11334918B2 against Samsung for the accused features. Third parties, however, receive no protection from this dismissal.
No Markman order or claim construction ruling was issued in this case. The action resolved via joint stipulation before any claim construction determination was published, meaning the scope of US11443344B2 and US11334918B2 was never judicially narrowed — leaving interpretive uncertainty relevant to third-party FTO assessments.
