USTA Technology v. Samsung: 802.11ac Wi-Fi Patent Action Dismissed With Prejudice
USTA Technology, LLC asserted reissue patent USRE047720E against Samsung’s 802.11ac Wi-Fi product portfolio — spanning enterprise access points, Galaxy smartphones, Chromebooks, and SmartThings mesh routers — in the Eastern District of Texas. After 271 days, both parties agreed to dismiss all claims and counterclaims with prejudice, permanently closing the litigation.
A Reissue Wi-Fi Patent Meets Samsung’s Broad Product Ecosystem in E.D. Texas
On June 7, 2024, USTA Technology, LLC filed suit against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. in the Eastern District of Texas before Judge Sean D. Jordan. The complaint asserted reissue patent USRE047720E — a patent covering 802.11ac Wi-Fi protocol technology — against a wide sweep of Samsung products, including the 400/500-series enterprise wireless access points (WEA514, WEA453, WEA403i, WEA514I), Galaxy and Galaxy Note smartphones, Galaxy Tab tablets, Samsung Chromebooks, SmartThings Wi-Fi Mesh Routers, and associated IEEE 802.11ac network adapter hardware and software.
The case closed on March 5, 2025, when both parties filed a joint stipulation of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Critically, all of USTA’s infringement claims were dismissed with prejudice, and all of Samsung’s counterclaims were likewise dismissed with prejudice. The with-prejudice designation means USTA is permanently barred from reasserting these specific claims against Samsung on USRE047720E — a materially stronger outcome for Samsung than a without-prejudice dismissal would have been.
The 271-day duration — under nine months from complaint to closure — is consistent with a negotiated resolution reached before significant merits litigation, likely prior to or shortly after claim construction proceedings. The public record does not disclose whether any financial consideration changed hands, which is typical of confidential settlements structured as stipulated dismissals. What is notable is that Samsung secured a with-prejudice bar, suggesting it had sufficient leverage — whether through prior art, non-infringement positions, or IPR threat — to extract that concession from USTA.

Dismissed with prejudice: what the stipulated exit means for both parties
Rule 41(a)(1)(A)(ii) dismissal: a jointly controlled exit
A stipulated dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii) requires consent from all parties and is self-executing — no court order needed. Here, both sides agreed to dismiss with prejudice simultaneously: USTA dismissed its infringement claims and Samsung dismissed its counterclaims. This mutual with-prejudice structure is a hallmark of a fully resolved dispute, not an abandonment. The court retains no ongoing jurisdiction absent an explicit retention clause in a settlement agreement.
Rule 41(a)(1)(A)(ii) stipulated dismissalWith prejudice: USTA cannot refile these claims against Samsung
The with-prejudice designation is the critical operative term. Unlike a without-prejudice dismissal — which preserves the plaintiff’s right to refile — a with-prejudice dismissal functions as an adjudication on the merits for res judicata purposes. USTA Technology is permanently barred from bringing the same infringement claims under USRE047720E against Samsung in any federal court. For Samsung, this is the most durable protection available short of a full invalidity ruling or IPR cancellation.
Permanent bar on refilingUSTA exits without a public merits ruling — but at a price
USTA Technology avoids the risk of an adverse claim construction or invalidity finding that could have weakened USRE047720E against other defendants. However, by dismissing with prejudice, USTA permanently surrendered its litigation position against Samsung specifically. If a financial settlement was reached — which the structure of the dismissal suggests — the terms remain undisclosed. USTA retains the right to assert USRE047720E against other parties not covered by this dismissal.
Patent survives for third-party assertionSamsung’s 802.11ac product lines cleared of this specific threat
Samsung’s enterprise access points, Galaxy smartphones, Chromebooks, and SmartThings mesh products are now shielded from future USTA claims under USRE047720E. For Samsung’s enterprise Wi-Fi business — competing against Cisco, Aruba, and Ruckus — removal of a reissue patent cloud on 802.11ac products has clear commercial value. Competitors and supply chain partners should note that this dismissal binds only Samsung; USTA’s patent remains live against other 802.11ac implementers in the market.

Official order — verbatim text
The dismissal order adopts verbatim the parties’ joint stipulation language under Rule 41(a)(1)(A)(ii), reflecting a fully consensual exit with no judicial merits determination. The symmetrical with-prejudice structure — USTA’s claims and Samsung’s counterclaims dismissed simultaneously — is significant: it extinguishes any future litigation between these parties under USRE047720E without creating claim construction or invalidity precedent that could affect USTA’s ability to pursue the same patent against other defendants. The absence of any fee or cost allocation language in the public record is consistent with a confidential settlement agreement governing economic terms.
USRE047720E — 802.11ac Wi-Fi wireless networking technology
USRE047720E is a reissue patent — a USPTO-granted correction or enhancement of an original patent, assigned application number US15/898404. Reissue patents undergo a second substantive examination and can expand or clarify claim scope within the bounds of the original disclosure. The patent covers technology in the 802.11ac Wi-Fi standard domain, which operates on the 5 GHz band and delivers multi-station WLAN throughput of at least 1 Gbps. The 802.11ac (Wi-Fi 5) standard underpins a vast installed base of enterprise access points, consumer routers, smartphones, tablets, and IoT devices manufactured globally.
The commercial stakes of this patent are substantial: 802.11ac remains the dominant deployed Wi-Fi generation for enterprise and consumer applications, with Wi-Fi 6 (802.11ax) still transitioning into mainstream deployment. USTA’s decision to assert the patent against Samsung’s full product breadth — from WEA-series enterprise APs to Galaxy smartphones and SmartThings mesh systems — signals a licensing strategy targeting high-volume Wi-Fi implementers. Any company manufacturing or selling products with 802.11ac chipsets should treat USRE047720E as a live enforcement risk until its claims are either adjudicated invalid or the patent expires.
Should you run an FTO check against USRE047720E?
Any company designing, manufacturing, or selling 802.11ac Wi-Fi products — including enterprise wireless access points, consumer mesh routers, smartphones, tablets, laptops, or IoT devices incorporating 802.11ac chipsets — should assess exposure to USRE047720E. USTA’s assertion against Samsung’s entire 802.11ac ecosystem demonstrates that the patent’s claimed scope may be read broadly across both infrastructure and client device product categories. The with-prejudice dismissal against Samsung does not affect USTA’s ability to assert this patent against other market participants.

What this case signals for the 802.11ac Wi-Fi patent licensing landscape
Reissue patent assertions against major OEMs in E.D. Texas continue to resolve privately — but the with-prejudice terms reveal meaningful negotiating dynamics.
Reissue patents remain potent Wi-Fi licensing tools — with elevated scrutiny risk
USRE047720E is a reissue patent, meaning it underwent a second USPTO examination. While reissues can broaden or clarify claims, they also face heightened invalidity arguments based on intervening rights and prosecution history. Samsung’s willingness to settle with prejudice — rather than pursue IPR cancellation — suggests USTA’s claims had sufficient merit to warrant resolution rather than a full merits fight.
E.D. Texas remains the jurisdiction of choice for Wi-Fi patent plaintiffs
The Eastern District of Texas continues to attract patent assertions in wireless technology, in part due to its scheduling order discipline and experienced patent bench. Judge Jordan’s docket moves efficiently — the 271-day resolution here is consistent with early-stage settlement pressure that E.D. Texas timelines create. Companies with 802.11ac or 802.11ax product exposure should treat E.D. Texas filings as requiring an immediate freedom-to-operate response.
USTA v Samsung — key questions answered
All claims were voluntarily dismissed with prejudice by stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii) on March 5, 2025. USTA Technology dismissed its infringement claims and Samsung dismissed its counterclaims, both with prejudice. USTA is permanently barred from reasserting these claims against Samsung under USRE047720E.
USTA asserted reissue patent USRE047720E (application number US15/898404) covering 802.11ac Wi-Fi wireless networking technology. The 802.11ac standard enables multi-gigabit wireless LAN throughput and is implemented across Samsung’s enterprise access points, Galaxy smartphones, Galaxy Tab tablets, Chromebooks, SmartThings mesh routers, and IEEE 802.11ac network adapter devices.
A dismissal with prejudice operates as a final adjudication on the merits for res judicata purposes. USTA Technology cannot refile the same infringement claims under USRE047720E against Samsung Electronics Co., Ltd. or Samsung Electronics America, Inc. in any federal court. However, USTA retains the right to assert USRE047720E against other defendants not party to this stipulation.
The accused products included Samsung’s 400/500-series enterprise wireless access points (WEA514, WEA453, WEA403i, WEA514I, WEA463e), the WDSA463E/XAR outdoor mesh access point, Samsung Galaxy and Galaxy Note smartphones, Galaxy Tab tablets, Samsung Chromebooks, SmartThings Wi-Fi Mesh Routers, and various IEEE 802.11ac network adapter devices with associated hardware and software.
The Eastern District of Texas is a preferred venue for patent plaintiffs due to its patent-specialised bench, established local patent rules, and historically plaintiff-friendly scheduling. Judge Sean D. Jordan, who was assigned the case, has significant experience with patent matters. The EDTX’s efficient case management creates settlement pressure that often leads to early resolution, consistent with this case’s 271-day lifespan.
