Gurvey v. Live Nation: Live Event Recording Patents Dismissed Without Prejudice
Pro se patent holder Amy Weissbrod Gurvey filed suit against Live Nation, Ticketmaster, and co-defendants alleging infringement of three patents covering live event ticketing, recording distribution, and UI design. After 704 days, the Central District of California dismissed claims against defendant Cowan Liebowitz without prejudice for failure to prosecute — one of multiple procedural hurdles that defined this litigation.
A multi-defendant live event IP dispute ends in procedural dismissal
Filed on June 3, 2023 in the Central District of California, this case pits patent holder Amy R. Weissbrod Gurvey against a broad set of defendants including Live Nation Entertainment, Ticketmaster, Instant Live Concerts, MLB Advanced Media, Phish/Phish Live, and several law firms. The patents at issue — US7603321B2, USD647910S, and US11043566B2 — relate to live event ticketing systems, recording and distribution technology, user interface design for live event platforms, and associated semiconductor structures.
The case closed on May 7, 2025 when the court dismissed claims against defendant Cowan Liebowitz and Latman PC without prejudice pursuant to Federal Rule of Civil Procedure 41(b). The dismissal followed plaintiff Weissbrod’s failure to comply with a March 13, 2025 Order to Show Cause, which had required her either to explain why claims against Cowan should not be dismissed for failure to diligently prosecute, or to file proof of service within 28 days. Neither was provided.
The 704-day duration without reaching the merits suggests persistent procedural and service difficulties throughout the litigation, consistent with the challenges frequently encountered in complex multi-defendant pro se patent actions. Notably, Weissbrod filed two petitions styled as writs of mandamus directed to the United States Supreme Court during proceedings; the district court took no action on either. The public record does not disclose whether claims against all other named defendants were separately resolved, settled, or remain pending.

Dismissed without prejudice: what the FRCP 41(b) ruling means for both sides
FRCP 41(b): Dismissal for failure to prosecute
Rule 41(b) allows a court to dismiss an action when a plaintiff fails to prosecute or comply with a court order. Here, Weissbrod did not respond to the March 13, 2025 Order to Show Cause within 28 days — triggering mandatory dismissal. Critically, the court ordered dismissal without prejudice, meaning the claims could theoretically be refiled, though practical and strategic barriers may remain.
Procedural dismissal — no merits rulingWithout prejudice: the door is not permanently closed
A dismissal without prejudice does not bar a future action on the same claims. Weissbrod retains the theoretical right to refile against Cowan Liebowitz, subject to applicable statutes of limitations and service requirements. However, a second filing would face heightened judicial scrutiny given the prior failure to prosecute, and any further procedural deficiencies would likely draw swifter consequences.
Refiling theoretically possibleCowan Liebowitz exits — without a merits win
Defendant Cowan Liebowitz and Latman PC obtains a dismissal but not a judgment on the merits. This means the firm cannot invoke res judicata to bar a future suit on the same patent claims. The absence of a fee award suggests the court did not find the case exceptional under 35 U.S.C. § 285 at this stage, though that determination was never squarely before the court.
No merits adjudicationLive event recording IP remains unlitigated on the merits
The three patents — covering live event ticketing-and-recording integration, UI design, and semiconductor structures — received no claim construction, validity ruling, or infringement determination. Companies operating in live event distribution, concert recording platforms, or digital ticketing should treat these patents as unresolved IP risk. The enforceability of US7603321B2 and US11043566B2 in particular remains untested by this litigation.

Official order — verbatim text
The court’s order is narrowly scoped: it dismisses claims against Cowan Liebowitz and Latman PC only, under FRCP 41(b), for two independently sufficient grounds — failure to prosecute and failure to obey a court order. The without-prejudice designation is notable; it suggests the court declined to impose the harsher sanction of a merits-preclusive dismissal, consistent with Ninth Circuit guidance favouring disposition on the merits where possible. No finding was made on patent validity, claim scope, or infringement. The court’s explicit refusal to act on the Supreme Court writ petitions underscores the limits of extraordinary relief during pending district proceedings.
US7603321B2 — Live Event Ticketing & Recording Distribution System
US7603321B2 (App. No. 11/253,912) claims an electronic system and method that integrates live event ticketing with the sale, distribution, and transmission of event recordings, including mastering system and intelligent terminal designs. This patent sits at the intersection of ticketing infrastructure and content distribution — a commercially sensitive area given the consolidation of ticketing and live streaming into unified platforms. USD647910S (App. No. 29/310,547) is a design patent protecting the ornamental appearance of a user interface for a display screen portion targeted at live events or travel. US11043566B2 (App. No. 16/599,116) covers semiconductor structures in a wide gate pitch region — the only hardware-level patent in the asserted set.
The combination of a utility patent covering a ticketing-recording integration system, a UI design patent, and a semiconductor structure patent suggests a broad enforcement strategy spanning software, interface, and hardware layers. US7603321B2 is commercially the most significant: it directly maps onto features now standard in live streaming ticketing platforms operated by defendants such as Live Nation and Ticketmaster. With no claim construction or infringement analysis produced in this case, the scope of these claims remains formally undetermined — a meaningful risk flag for any company operating in integrated live event technology.
Should your platform run an FTO check against US7603321B2?
Any company building or operating a platform that couples live event ticketing with recording sale, distribution, or transmission — whether through on-demand concert recordings, live streaming with ticketed access, or integrated venue media systems — should treat US7603321B2 as a live FTO concern. The patent has not been invalidated, has not been subjected to IPR, and has produced no claim construction record. The dismissal in this case was purely procedural and confers no legal protection on third parties.
PatSnap Eureka’s FTO Search Agent can map the claim language of US7603321B2, USD647910S, and US11043566B2 against your product architecture, flag prior art candidates that could support an IPR petition, and identify design-around opportunities before you face a demand letter. Given the breadth of defendants named in this case — spanning entertainment giants to media rights firms — proactive clearance is materially lower cost than reactive defence in the Central District of California.

What this case signals for the live event and digital ticketing IP landscape
This procedural outcome leaves three live event technology patents unexamined — signalling continued uncertainty for platforms in the space.
FRCP 41(b) dismissals do not extinguish patent rights
A without-prejudice dismissal for failure to prosecute means no court has ruled on validity, infringement, or claim scope. The patents US7603321B2 and US11043566B2 remain issued and enforceable on their face. Companies in live event recording and digital ticketing distribution should not treat this outcome as clearance — a future action remains legally viable within limitations periods.
Multi-defendant patent cases carry elevated procedural risk for plaintiffs
This case named nine defendants across entertainment, media, and legal services — a configuration that substantially complicates service, scheduling, and resource management. The failure-to-prosecute dismissal suggests coordination across such a broad defendant group exceeded available plaintiff capacity. IP practitioners advising patent holders should flag this concentration risk early in litigation planning.
Gurvey v Live — key questions answered
Amy Weissbrod Gurvey sued Live Nation, Ticketmaster, and multiple co-defendants in the Central District of California alleging infringement of three patents covering live event recording distribution, UI design, and semiconductor structures. After 704 days, the court dismissed claims against defendant Cowan Liebowitz without prejudice under FRCP 41(b) for failure to prosecute and failure to comply with a court order. No merits ruling was issued.
A Rule 41(b) dismissal without prejudice does not affect the validity or enforceability of the asserted patents. The court made no ruling on infringement or claim scope. Weissbrod retains the right to refile claims within applicable statutes of limitations. The patents US7603321B2, USD647910S, and US11043566B2 remain issued and face no legal bar from this dismissal.
Three patents were asserted: US7603321B2 (an electronic system coupling live event ticketing with recording distribution), USD647910S (a design patent for a live event or travel UI display screen), and US11043566B2 (semiconductor structures in a wide gate pitch region). The combination spans software, design, and hardware technology layers.
Weissbrod filed two documents styled as petitions for writs of mandamus and prohibition directed to the U.S. Supreme Court while the district case was active. The district court declined to act on either petition, as they were addressed to a different tribunal. Such filings have no operative effect at the district level and are procedurally extraordinary at this stage of litigation.
No. The dismissal was issued only as to claims against Cowan Liebowitz and Latman PC, and it was without prejudice. The public record does not confirm that claims against Live Nation, Ticketmaster, or other defendants were resolved on the merits. All named defendants should treat the asserted patents as unresolved IP exposure until validity and infringement are adjudicated or the patents expire.
