RecepTrexx LLC v. Ringover Inc. — Voluntary Dismissal With Prejudice in 113 Days
RecepTrexx LLC filed suit against cloud communications provider Ringover Inc. in the District of Massachusetts asserting reissue patent USRE042997E, which covers triggered playback of recorded messages to incoming cellular calls. The case ended in a voluntary dismissal with prejudice just 113 days after filing — before Ringover had answered the complaint.
Reissue patent asserted against cloud telephony provider ends abruptly
On 1 February 2024, RecepTrexx LLC filed a patent infringement complaint in the U.S. District Court for the District of Massachusetts (Case No. 1:24-cv-10271) against Ringover Inc., a cloud-based business communications platform. The sole patent asserted was USRE042997E, a reissue patent with underlying application number US12/001974, protecting technology for the triggered playback of recorded messages to incoming telephone calls directed to a cellular phone. Judge Nathaniel M. Gorton was assigned to the case.
The case closed on 24 May 2024 — just 113 days after filing — when RecepTrexx invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i) to voluntarily dismiss the action with prejudice. Critically, the dismissal was filed before Ringover had answered the complaint or moved for summary judgment, meaning RecepTrexx retained the unilateral right under Rule 41 to file the notice without court approval. The with-prejudice designation, however, means RecepTrexx permanently forfeited the right to assert the same claims against Ringover again.
A resolution within 113 days — before any substantive defence had been entered — is notably swift and typically suggests either a settlement reached quietly outside the public record, a licensing arrangement, or a plaintiff decision to abandon the specific claims. No fee award or cost allocation appears in the public record, leaving the commercial terms, if any, undisclosed. The absence of defendant counsel filings throughout the docket is consistent with a dispute resolved before Ringover formally engaged litigation counsel.

Voluntarily dismissed with prejudice: what the Rule 41 filing means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit right
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice of dismissal before the defendant has served an answer or a motion for summary judgment. RecepTrexx exercised this right here. Because no court approval was needed, the dismissal was effective upon filing. The with-prejudice designation — which goes beyond the rule’s default of without prejudice — was RecepTrexx’s voluntary choice and permanently bars the same claims against Ringover.
Procedural dismissal — no merits rulingWith-prejudice dismissal extinguishes claims against Ringover permanently
By electing a with-prejudice dismissal, RecepTrexx surrendered any future right to sue Ringover on the same patent claims. This is a stronger concession than a default Rule 41 exit, which would have preserved the option to refile. Whether this reflects a negotiated settlement, a licensing payment, or a unilateral decision to drop the action is not apparent from the public record. USRE042997E itself remains in force and could still be asserted against other defendants.
Claims against Ringover permanently barredRingover exits without admitting liability or filing a single pleading
Ringover Inc. secured a complete resolution of the infringement action without filing an answer, invalidity counterclaim, or summary judgment motion. No adverse finding was made. The with-prejudice dismissal gives Ringover durable protection against the same claims from the same plaintiff, though it does not constitute a judicial finding of non-infringement or invalidity that could bind third parties. Ringover’s product continues to operate absent any injunctive constraint.
No liability finding; full protection securedUSRE042997E survives and remains a threat to other cloud telephony players
The dismissal resolves only the Ringover dispute. USRE042997E — covering triggered playback of recorded messages to incoming cellular calls — has not been invalidated or adjudicated. Competing providers of cloud telephony, auto-attendant, or voicemail-drop features should note that the patent is still live. The rapid pre-answer resolution suggests RecepTrexx’s assertion strategy may include multiple targets, and other companies offering similar call-handling automation features may face similar claims.

Official order — verbatim text
The dismissal notice cites Rule 41(a)(1)(A)(i) and expressly states that Ringover had not yet answered or moved for summary judgment — language that confirms RecepTrexx’s unilateral authority to act without judicial approval. The voluntary addition of ‘with prejudice’ is significant: Rule 41’s default for a unilateral notice is without prejudice, so this represents a deliberate, plaintiff-elected upgrade. For Ringover, the practical effect is a permanent bar to the same claims; for RecepTrexx, the patent itself is unaffected and enforceable against others.
USRE042997E — Triggered Playback of Recorded Messages to Cellular Calls
USRE042997E is a U.S. reissue patent with underlying application number US12/001974, meaning the original patent was subsequently returned to the USPTO for correction or broadening of claim scope — a process that involves re-examination of the claims by a patent examiner. The patent protects technology for triggering the playback of pre-recorded messages when an incoming telephone call is directed to a cellular phone, a core function underpinning auto-attendant, voicemail-drop, and inbound call routing features in cloud telephony systems.
The reissue designation makes USRE042997E strategically notable: corrected claims may have broader or more precisely targeted scope than the original grant, and the USPTO’s re-examination lends the claims additional credibility against certain validity attacks. For UCaaS providers, virtual phone system vendors, and any platform that intercepts or processes inbound cellular calls with pre-recorded audio responses, this patent represents a live enforcement risk. The product category — triggered cellular call playback — sits at the intersection of VoIP infrastructure and automated call handling, a space occupied by dozens of commercial platforms.
Should your product team run an FTO against USRE042997E?
Any company building or operating cloud telephony infrastructure that plays pre-recorded audio in response to inbound cellular calls should consider a freedom-to-operate review against USRE042997E. This includes UCaaS platforms, virtual receptionist services, ringless voicemail providers, auto-attendant systems, and IVR vendors. The patent has not been adjudicated on the merits — no claim has been invalidated, and no non-infringement finding has been made — leaving its full enforcement potential intact.
PatSnap Eureka’s FTO Search Agent can map the claim language of USRE042997E against your product’s technical architecture, surface prior art that may support an invalidity argument, and identify whether any continuation or related family members extend the risk perimeter. For product teams evaluating inbound call automation features, running this analysis before launch or before a licensing demand arrives is materially cheaper than responding to litigation in the District of Massachusetts.

What this case signals for the cloud telephony IP landscape
A reissue patent on cellular voicemail playback, a pre-answer exit, and a with-prejudice bar — three signals worth unpacking.
Pre-answer dismissals with prejudice often indicate a private resolution
When a plaintiff voluntarily dismisses with prejudice before the defendant has even answered, it typically signals one of two things: a confidential licensing or settlement agreement, or a calculated decision to abandon a weak position before incurring further cost. The absence of any defendant counsel filings here is consistent with an early-stage negotiation resolved off-docket. Teams monitoring RecepTrexx’s assertion activity should watch for similar filings against other cloud communications defendants.
USRE042997E remains unlitigated on the merits — FTO exposure persists
No court has ruled on the validity or scope of USRE042997E. Any cloud telephony, UCaaS, or auto-attendant product that triggers playback of pre-recorded audio to inbound cellular calls should assess its exposure. Reissue patents carry corrected claim language reviewed by the USPTO, which can make them harder to attack on formal grounds. An FTO analysis against this patent is prudent for any company operating in the inbound call automation space.
RecepTrexx v Ringover — key questions answered
The with-prejudice dismissal under Rule 41(a)(1)(A)(i) permanently bars RecepTrexx from asserting the same claims of USRE042997E against Ringover Inc. in any future action. It does not, however, affect RecepTrexx’s ability to sue other defendants or to enforce the patent more broadly.
No. The RecepTrexx v. Ringover case was dismissed before any substantive pleading was filed by the defendant, meaning no court has ruled on the validity, enforceability, or scope of USRE042997E. The patent remains in force as issued.
A reissue patent is one that has been returned to the USPTO after original grant to correct errors or adjust claim scope. USRE042997E underwent this process, meaning its claims were re-examined. Reissue claims may be broader or more precise than the original, and the USPTO review can make certain invalidity arguments harder to sustain without dedicated IPR or reexamination proceedings.
The case closed before Ringover filed any responsive pleading, which is consistent with either a confidential settlement or licensing agreement, or a plaintiff decision to abandon the action. The public record does not disclose the commercial terms, if any. The speed and the with-prejudice designation together suggest a negotiated resolution is more likely than a unilateral abandonment, though this cannot be confirmed from publicly available filings.
USRE042997E covers triggered playback of pre-recorded messages to inbound cellular telephone calls. Products potentially within scope include UCaaS platforms, auto-attendant systems, IVR solutions, voicemail-drop services, virtual receptionist tools, and any cloud communications product that plays pre-recorded audio in response to an incoming cellular call. Companies operating in this space should assess their FTO exposure, particularly given the patent has not been adjudicated on the merits.
