AML IP v. Cinemark USA: Voluntary Dismissal Without Prejudice
AML IP, LLC filed and same-day voluntarily dismissed a patent infringement action against Cinemark USA, Inc. in the Northern District of Texas over US7177838B1, a patent covering electronic commerce transactions using electronic tokens. The dismissal is expressly without prejudice, leaving the asserted patent and future claims in play.
A same-day filing and dismissal in Texas over e-commerce token patents
On 17 April 2026, AML IP, LLC filed a patent infringement action against Cinemark USA, Inc. in the Northern District of Texas (Case No. 3:26-cv-01252), before Judge Sam A. Lindsay. The sole patent asserted was US7177838B1 (application no. US09/553695), directed to a method and apparatus for conducting electronic commerce transactions using electronic tokens. Cinemark USA, Inc. — a major cinema operator — was named as the defendant.
The recorded basis of termination is 'Voluntary dismissal.' The docket order states that AML IP filed a notice of voluntary dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), on the ground that Cinemark had not yet answered or filed a motion for summary judgment. The dismissal is expressly stated to be without prejudice as to the asserted patent, and each party is to bear its own costs, expenses, and attorneys' fees.
The same-day filing and dismissal is notable. Because the dismissal is without prejudice, AML IP retains the right to assert US7177838B1 against Cinemark or other defendants in a future action. The specific circumstances that prompted the filing and immediate withdrawal are not disclosed in the available public record.

US7177838B1 — electronic commerce transactions using electronic tokens
Any company operating an electronic token-based commerce platform — including digital ticketing, prepaid instruments, loyalty point systems, or tokenised payment flows — should assess its exposure to US7177838B1. The without-prejudice dismissal in this case means the patent has not been adjudicated, invalidated, or found unenforceable, leaving its claim scope fully intact as an enforcement instrument.
Official order — verbatim text
The voluntary dismissal notice invokes Rule 41(a)(1)(A)(i) and expressly states the dismissal is without prejudice as to the asserted patent, with each party bearing its own costs. No merits determination was made. The without-prejudice designation means the patent remains available for future assertion, and no estoppel or res judicata effect arises from this dismissal as to AML IP's claims.
Voluntarily dismissed: what the without-prejudice ruling means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right before defendant responds
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order simply by filing a notice — but only before the defendant has served an answer or a motion for summary judgment. That procedural window was expressly invoked here, making this a unilateral plaintiff-side act requiring no judicial approval and resulting in no merits adjudication.
Plaintiff-initiated, no merits rulingWithout prejudice: the case ended, but the patent claim did not
A dismissal without prejudice does not extinguish the underlying patent claim. AML IP explicitly reserved its position as to the asserted patent, US7177838B1. This means AML IP may refile against Cinemark or assert the same patent against other parties in a future action. Whether this dismissal reflects a negotiated resolution, a tactical pause, or a straightforward withdrawal is not disclosed in the available public record.
Patent claims survive dismissalCinemark exits — for now — with no judgment against it
Because the dismissal is without prejudice and Cinemark never answered, no finding of infringement, validity, or damages was made. Cinemark bears no cost award. However, the without-prejudice nature of the dismissal means the litigation risk associated with US7177838B1 is not definitively resolved for Cinemark or others operating in the electronic commerce transactions space.
No finding against defendantUS7177838B1 remains a live enforcement risk for e-commerce operators
The without-prejudice dismissal keeps US7177838B1 available for future assertion. Companies using electronic token-based commerce transaction systems — including ticketing, loyalty, and digital payment platforms — should note that this patent has not been adjudicated on the merits, invalidated, or licensed on any publicly disclosed terms. The specific terms of any arrangement between the parties are not disclosed in the available record.

What this case signals for the electronic commerce patent IP landscape
A same-day voluntary dismissal without prejudice is a pattern associated with pre-suit resolution or tactical repositioning — not a final conclusion.
Same-day dismissals often signal rapid pre-litigation activity
When a plaintiff files and dismisses on the same day under Rule 41(a)(1)(A)(i), it typically suggests that the filing itself served a purpose — whether that is creating negotiating leverage, triggering a deadline, or responding to an off-docket development. The public record here does not disclose the specific reason.
Without-prejudice language is a red flag for potential targets in this tech space
The explicit without-prejudice reservation as to US7177838B1 signals that AML IP is preserving optionality. Operators of electronic token-based commerce platforms — ticketing, digital payments, loyalty systems — should monitor this patent and AML IP's future filing activity as an active enforcement risk.
