USTA Technology v. LG Electronics: 802.11ac Wi-Fi Patent Suit Dismissed Without Prejudice
USTA Technology, LLC filed suit against LG Electronics in the Eastern District of Texas asserting reissued patent USRE047720E against a broad range of LG’s 802.11ac-compliant products. The case was voluntarily dismissed without prejudice before LG answered the complaint — leaving the door open for refiling.
Pre-Answer Voluntary Dismissal in a Broad 802.11ac Wi-Fi Infringement Action
USTA Technology, LLC filed this patent infringement action on June 7, 2024 in the Eastern District of Texas before Judge Sean D. Jordan. The suit asserted reissued patent USRE047720E — covering 802.11ac Wi-Fi technology — against LG Electronics, Inc. and LG Electronics USA, Inc. The accused product range was notably broad, spanning LG Chromebooks, mobile phones including the K92 and V30, the STB-6500 set-top box, multiple television lines including the 55NANO80AQA, tablets, and a wide array of wireless access points.
The case closed on January 21, 2025, just 228 days after filing, when USTA Technology filed a voluntary notice of dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because LG had not yet served an answer to the complaint, no court order was required. The dismissal was expressly without prejudice, meaning USTA Technology retains the right to refile the same claims. Each party was ordered to bear its own costs, expenses, and attorneys’ fees.
The pre-answer timing of this dismissal is commercially significant. It suggests the case resolved — or was strategically withdrawn — before substantive litigation costs escalated significantly. The public record does not reveal whether a licensing agreement, settlement negotiation, or purely tactical repositioning drove the withdrawal. The without-prejudice designation means this dispute cannot be treated as finally resolved, and LG’s 802.11ac product portfolio remains exposed to potential re-assertion of USRE047720E.

Voluntarily dismissed without prejudice: what this resolution means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right before answer
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice of dismissal at any time before the defendant serves an answer. Because LG had not yet answered, USTA Technology exercised this right unilaterally. No judicial approval was needed, and the court issued no merits ruling. The case terminates procedurally, not substantively.
No merits adjudicationWithout prejudice: the patent claims survive this dismissal
A dismissal without prejudice does not extinguish the underlying patent claims. USTA Technology may refile an identical or substantially similar action against LG at a future date, subject to applicable statutes of limitations. This contrasts with a dismissal with prejudice, which would bar re-litigation. The public record does not disclose whether any confidential settlement or licensing terms accompanied this dismissal.
Refiling remains possibleUSTA Technology retains full enforcement optionality
By dismissing without prejudice before LG answered, USTA Technology avoids any adverse ruling, preserves the validity of USRE047720E for future enforcement, and limits litigation spend at this stage. Whether this reflects a concluded licensing deal, ongoing negotiations, or a tactical pivot to a different forum or defendant set is not determinable from the public docket alone.
Patent enforceability preservedLG escapes this action but faces residual exposure
LG Electronics avoids a merits ruling and any damages exposure in this action. However, the without-prejudice dismissal means the threat is not extinguished. LG’s broad 802.11ac product portfolio — televisions, phones, tablets, Chromebooks, set-top boxes, and access points — remains potentially exposed if USTA Technology refiles. The each-party-bears-own-costs term means LG recovers no legal fees from this proceeding.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) precisely because no answer had been served — a procedural detail that eliminates any need for court intervention and leaves the record free of adverse findings. The explicit without-prejudice designation is the operative term: it preserves USTA Technology’s cause of action in full. The each-party-bears-own-costs provision, standard in pre-answer voluntary dismissals, provides no fee-shifting signal about relative litigation strength.
USRE047720E — Reissued 802.11ac Wi-Fi Wireless Connectivity Patent
USRE047720E is a United States reissued patent, originating from application US15/898404. Reissued patents undergo re-examination by the USPTO to correct errors or broaden claims beyond the original grant, and carry the same legal force as an original patent from the reissue date. The patent covers technology within the IEEE 802.11ac Wi-Fi standard — the fifth generation of Wi-Fi operating on the 5 GHz band, widely deployed in consumer electronics, networking equipment, and mobile devices from approximately 2013 onward.
Asserting a reissued 802.11ac patent against a device OEM like LG carries significant commercial weight: 802.11ac compliance is effectively ubiquitous in consumer electronics sold after 2015, meaning the potential royalty base is enormous. The breadth of accused products in this complaint — spanning multiple LG product categories — is consistent with a standard-related patent being leveraged across an entire product ecosystem rather than targeting a specific implementation. Competitors and suppliers operating in the Wi-Fi device space should assess their own exposure to USRE047720E.
Should your 802.11ac product line face an FTO assessment for USRE047720E?
Any company designing, manufacturing, importing, or selling 802.11ac-compliant devices in the United States should consider whether USRE047720E creates freedom-to-operate risk. The accused product set in this case — televisions, mobile phones, tablets, Chromebooks, set-top boxes, and wireless access points — covers the mainstream consumer electronics category broadly. The without-prejudice dismissal means the patent remains in force and available for enforcement against LG or any other 802.11ac implementer.
PatSnap Eureka’s FTO Search Agent can map USRE047720E’s claim scope against your specific product architecture, identify prosecution history estoppel that may limit claim reach, and surface prior art that could support an IPR petition if the patent is re-asserted against your organisation. Given the reissued status of the patent, reviewing the reissue prosecution history for claim amendments is a particularly important step in any FTO analysis.

What this case signals for the 802.11ac Wi-Fi patent licensing landscape
Pre-answer voluntary dismissals in E.D. Texas often signal licensing activity or strategic repositioning — rarely a clean exit.
Reissued standard-essential patents carry elevated enforcement risk
USRE047720E is a reissued patent, meaning the USPTO reviewed and broadened or corrected the original claims post-grant. Reissued patents asserted against IEEE 802.11ac-compliant products suggest the claim scope may have been deliberately widened to capture standard-implementing devices — a pattern common in Wi-Fi NPE campaigns.
E.D. Texas pre-answer dismissals rarely signal permanent withdrawal
When a plaintiff files in the Eastern District of Texas and dismisses before the defendant answers, it is consistent with ongoing licensing negotiations or a planned re-filing. Companies operating in the 802.11ac ecosystem — device OEMs, chipset vendors, and access point manufacturers — should monitor USTA Technology’s docket activity for follow-on actions.
USTA v LG — key questions answered
USTA Technology, LLC filed a patent infringement suit against LG Electronics, Inc. and LG Electronics USA, Inc. in the Eastern District of Texas on June 7, 2024, asserting reissued patent USRE047720E covering 802.11ac Wi-Fi technology. The case was voluntarily dismissed without prejudice on January 21, 2025, before LG filed an answer, under FRCP 41(a)(1)(A)(i). Each party bears its own costs.
A dismissal without prejudice does not extinguish the underlying patent or cause of action. USTA Technology retains the right to refile an infringement suit asserting USRE047720E against LG or other defendants in the future, subject to the applicable six-year damages lookback period. The patent itself remains valid and enforceable until its expiration or a successful post-grant challenge.
USRE047720E is a USPTO reissued patent derived from application US15/898404, covering technology related to the IEEE 802.11ac Wi-Fi standard. Reissued patents may have broadened or corrected claims relative to the original grant. Because 802.11ac compliance is standard in virtually all post-2015 consumer Wi-Fi devices, a reissued patent in this space can theoretically cover an extremely wide range of commercial products.
The public record does not disclose the reason for the pre-answer dismissal. Common explanations in similar E.D. Texas NPE cases include entry into a licensing or settlement agreement, strategic decision to refile in a different venue, or a tactical pause in enforcement activity. The without-prejudice designation and mutual cost-bearing provision are consistent with either a negotiated resolution or a voluntary tactical withdrawal.
Yes. Because the dismissal was without prejudice, USTA Technology could refile an action asserting USRE047720E against LG in the same or a different court. LG’s exposure across its 802.11ac product portfolio — including televisions, mobile phones, tablets, Chromebooks, set-top boxes, and access points — would remain relevant in any re-filed action. Companies in similar product categories should also monitor this patent for enforcement against their own product lines.
