RecepTrexx v. TCL Technology: Patent Infringement Action Voluntarily Dismissed
RecepTrexx, LLC asserted reissue patent USRE042997E — covering triggered playback of recorded messages to incoming cellular calls — against TCL Technology Group in the Western District of Texas. The case closed after 299 days when the plaintiff voluntarily dismissed without the defendant ever filing an answer.
Reissue patent assertion against TCL ends at the pleading stage
On 7 July 2023, RecepTrexx, LLC filed a patent infringement action against TCL Technology Group, Corp. in the Western District of Texas (Case No. 6:23-cv-00487) before Judge Orlando L. Garcia. The asserted patent, USRE042997E, is a reissue patent covering the triggered playback of recorded messages to incoming telephone calls on a cellular phone — a technology directly relevant to TCL’s consumer handset portfolio.
The case closed on 1 May 2024 when RecepTrexx filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i). That procedural mechanism is available only where the defendant has not yet served an answer or a motion for summary judgment — and the filing confirms TCL had done neither. The public record does not further specify any settlement terms, licensing arrangement, or financial consideration exchanged between the parties.
At 299 days, the case lasted nearly ten months before ending at the earliest possible procedural exit point. The timing and mechanism are consistent with patterns seen in NPE litigation where early pre-answer dismissal may reflect a private resolution, a strategic reassessment of claim scope, or a licensing outcome not reflected in the public docket. The absence of any defendant agent or law firm on record further limits what can be inferred about TCL’s posture in the dispute.

Voluntarily dismissed: what the Rule 41 filing means for both parties
Rule 41(a)(1)(A)(i): unilateral exit before defendant answers
Federal Rule of Civil Procedure 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order at any time before the defendant serves an answer or a motion for summary judgment. The filing here confirms TCL had taken neither step. This mechanism gives the plaintiff full control over the exit — no judicial approval required — and leaves the docket silent on merits.
Pre-answer dismissalWith or without prejudice? The public record is silent
A Rule 41(a)(1) voluntary dismissal is without prejudice by default unless the notice itself states otherwise, or unless the plaintiff has previously dismissed the same claim. The filing references dismissal ‘without prejudice’, meaning RecepTrexx retains the theoretical right to refile. However, the public record does not disclose whether any side agreement, licensing deal, or covenant not to sue was reached privately — which could effectively resolve the dispute with prejudice.
Without prejudice on recordTCL exits without adjudication — no invalidity finding on record
TCL Technology avoided any merits ruling on USRE042997E. No invalidity finding, no non-infringement judgment, and no fee award was entered. While this is a clean procedural exit, it provides TCL with no formal shield against a future assertion of the same patent — either by RecepTrexx or a subsequent assignee. The lack of any recorded defendant counsel suggests TCL’s litigation posture was minimal throughout.
No merits adjudicationUSRE042997E remains enforceable and unlitigated on the merits
The voluntary dismissal leaves USRE042997E fully intact as an enforceable asset. Other smartphone OEMs and cellular device manufacturers whose products involve triggered playback of recorded messages to incoming calls should treat this patent as a live risk. The absence of any IPR filing or invalidity challenge on the record means the patent’s claims have not been stress-tested in adversarial proceedings.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly confirms that TCL had neither answered the complaint nor moved for summary judgment — the twin preconditions for this unilateral exit. The ‘without prejudice’ designation means the action is terminated without a merits ruling and with no estoppel effect on the patent’s validity or RecepTrexx’s future enforcement rights. For TCL, the procedural outcome is clean but provides no formal invalidity shield.
USRE042997E — triggered playback of recorded messages to cellular calls
USRE042997E is a United States reissue patent — granted through the USPTO’s reissue process to correct or broaden the claims of an original grant. The underlying application number US12/001974 indicates a filing in the late 2000s smartphone era. The patent covers the triggered playback of recorded messages in response to incoming telephone calls on a cellular phone, a function that intersects with voicemail, auto-reply, and call-screening features embedded in modern handset software and firmware.
Reissue patents are strategically significant because they represent a deliberate post-grant effort by the patentee to strengthen claim coverage — making them higher-risk assets for OEMs to design around. For the cellular device sector, any product feature that automatically plays or delivers a pre-recorded audio response to an incoming call may fall within the asserted claim scope. TCL’s broad handset portfolio makes it a logical enforcement target, and the same logic applies to other major Android OEMs operating in comparable product categories.
Should your product team run an FTO against USRE042997E?
Any company shipping smartphones, feature phones, or telephony-enabled devices with call-handling automation — including voicemail, auto-reply audio, do-not-disturb message playback, or similar triggered response features — should consider a freedom-to-operate review against USRE042997E. The fact that this case ended without a validity ruling means the patent’s claims remain presumptively valid and have never been tested in IPR or district court merits proceedings.
PatSnap Eureka’s FTO Search Agent can map the claim language of USRE042997E against your product’s call-handling architecture, flag prior art that could support an IPR petition, and identify related continuation or reissue applications in the same family. For in-house IP teams at device OEMs, running this analysis now — before a demand letter arrives — is substantially cheaper than responding reactively in W.D. Texas litigation.

What this case signals for the cellular telephony IP landscape
A pre-answer dismissal without public terms is one of the most common outcomes in NPE assertion campaigns — and one of the least transparent.
Pre-answer exits often mask private licensing outcomes
When a plaintiff voluntarily dismisses before the defendant answers, the most commercially significant detail — whether money or a license changed hands — is rarely on the public docket. Competitors of TCL in the handset space should not read this dismissal as a signal that USRE042997E lacks strength; it may simply have been resolved quietly.
Reissue patents carry expanded claim risk for device OEMs
USRE042997E is a reissue patent, meaning its claims were broadened or corrected post-grant to improve enforceability. Device manufacturers in the cellular telephony space — particularly those with call-handling, voicemail, or auto-reply features — should scrutinise reissue patents more carefully than standard grants when assessing FTO exposure.
RecepTrexx v TCL — key questions answered
RecepTrexx LLC filed a patent infringement action against TCL Technology Group in the Western District of Texas on 7 July 2023, asserting reissue patent USRE042997E. The case was voluntarily dismissed by the plaintiff on 1 May 2024 under Rule 41(a)(1)(A)(i), before TCL filed any answer. The dismissal is recorded as without prejudice; no merits ruling was issued.
USRE042997E is a reissue patent covering the triggered playback of recorded messages to incoming telephone calls on a cellular phone. TCL Technology is a major smartphone OEM whose handset products incorporate call-handling features that may intersect with this claim scope. Reissue patents are frequently asserted in NPE campaigns because their claims have been post-grant refined for enforcement breadth.
A Rule 41(a)(1)(A)(i) dismissal without prejudice means the plaintiff may refile the same claims in future. It creates no estoppel, no invalidity finding, and no non-infringement ruling. The patent remains fully enforceable. TCL and similarly situated defendants should treat the dismissal as procedurally neutral rather than as a substantive resolution of the patent’s merits.
The public docket does not disclose any settlement agreement, licensing terms, or financial consideration. The voluntary dismissal mechanism used — Rule 41(a)(1)(A)(i) — does not require court approval or public filing of any settlement terms. A private agreement may have been reached, but this cannot be confirmed from the available public record.
Yes — the voluntary dismissal leaves USRE042997E valid and unlitigated on the merits. No IPR petition or invalidity judgment exists on the record. Device manufacturers with triggered call-response or auto-reply audio features in their handsets remain potential enforcement targets. An FTO analysis and monitoring of any new assignments or continuation filings related to this patent family is advisable.
