IP Law Daily, TRADEMARK—D. Del.: Court denies Game Show Network’s summary judgment bid in CINEMAVAULT trademark dispute, (Mar 18, 2026)

By Saurabh Kashyap, B.A., M.A., LL.B., LL.M.

Triable issues remained on continuous use of the CINEMAVAULT mark and the likelihood of confusion with the CINEVAULT streaming brand.

The federal district court in Wilmington, Delaware, has denied a motion for summary judgment filed by Game Show Network LLC in a trademark infringement action brought by Cinemavault, Inc., concluding that genuine disputes of material fact existed regarding the plaintiff’s continued use of its CINEMAVAULT mark and whether the defendant’s CINEVAULT streaming service was likely to cause consumer confusion. Because the record contained conflicting evidence regarding abandonment, judicial estoppel, and the likelihood-of-confusion factors applied by the Third Circuit, the court held that the dispute must be resolved by a jury rather than on summary judgment (Cinemavault, Inc. v. Game Show Network, LLC, No. 1:23-cv-00032-JHS (D. Del. Mar. 17, 2026)).

Background. The plaintiff, Cinemavault, Inc., is engaged in acquiring and distributing motion picture content and related media assets for commercial distribution. The defendant, Game Show Network LLC, operates television and digital streaming services and is a subsidiary of Sony Pictures Television.

The conflict arose when the network adopted the name CINEVAULT for one of its streaming brands, which Cinemavault contended was confusingly similar to its longstanding CINEMAVAULT brand used in connection with its film acquisition and distribution business. Its predecessor began using the mark CINEMAVAULT.COM in September 2000 for online retail, merchandising, and motion picture distribution services. The mark was registered with the U.S. Patent and Trademark Office in December 2005, before the registration later lapsed in 2012.

According to the plaintiff, it continued to use the CINEMAVAULT designation through affiliated entities and ongoing film-related activities, including licensing and management of motion picture rights. The company also asserted that its ongoing operations and planned streaming initiatives preserved its trademark rights despite the lapse of the earlier federal registration.

Game Show Network adopted the CINEVAULT brand in October 2020 after internal branding discussions and trademark clearance searches conducted by outside counsel. Those searches revealed an expired CINEMAVAULT.COM trademark registration and a website operating under the same name, but the network concluded that no material obstacles prevented adoption of the CINEVAULT mark.

The company subsequently filed an intent-to-use trademark application for CINEVAULT with the USPTO in November 2020, which matured into a federal registration in March 2022 for entertainment and streaming-related services.

Cinemavault later filed suit alleging trademark infringement and unfair competition under Section 43(a) of the Lanham Act, 15 U.S.C. §1125(a). Game Show Network moved for summary judgment, arguing that the plaintiff’s claims failed as a matter of law because the CINEMAVAULT mark had not been continuously used, the plaintiff should be judicially estopped from asserting confusion, and the likelihood-of-confusion factors weighed decisively in the defendant’s favor.

Continuous use of the mark. The court first addressed whether Cinemavault had abandoned its trademark due to a lack of continuous use. The defendant argued that the plaintiff ceased meaningful use of the CINEMAVAULT mark after selling portions of its film distribution rights and allowing its earlier federal registration to lapse.

The court concluded that the evidentiary record did not conclusively establish abandonment. Evidence showed that Cinemavault and related entities continued to hold film rights and had taken steps toward developing a streaming platform under the CINEMAVAULT name. The court found that these activities could support a finding that the mark remained in commercial use. Because trademark abandonment requires proof of nonuse and intent not to resume use, the court held that the issue presented a factual dispute unsuitable for summary judgment.

Judicial estoppel. Game Show Network also argued that Cinemavault should be judicially estopped from asserting its trademark claims because of allegedly inconsistent statements in earlier proceedings or filings concerning its business operations and trademark rights.

The court rejected that argument, explaining that judicial estoppel generally applies only when a party successfully persuades a court to adopt a prior inconsistent position. The court noted that the doctrine is intended to protect the integrity of the judicial process rather than to punish inconsistent litigation strategies. Because the defendant failed to demonstrate that a court had previously accepted an inconsistent position by Cinemavault, judicial estoppel did not bar the plaintiff’s claims.

Likelihood of confusion. The court also determined that the likelihood-of-confusion inquiry could not be resolved on summary judgment. In the Third Circuit, courts evaluate trademark confusion using the multi-factor framework established in Interpace Corp. v. Lapp, Inc., 721 F.2d 460 (3d Cir. 1983). These “Lapp factors” examine elements such as the similarity of the marks, the strength of the senior mark, evidence of actual confusion, the marketing channels used by the parties, and the degree of care exercised by consumers.

The court explained that several of those factors were disputed in the present case. The similarity of the marks CINEMAVAULT and CINEVAULT could reasonably support competing conclusions regarding the likelihood that consumers would associate the two brands with a single source. Likewise, the commercial strength and marketplace recognition of the CINEMAVAULT mark were contested issues, particularly in light of the plaintiff’s long history in film distribution and the defendant’s more recent entry into streaming services.

The record also contained conflicting evidence regarding marketing channels and consumer exposure. Both companies operated in the broader field of film distribution and streaming media, raising the possibility that consumers might encounter the marks in overlapping entertainment markets. The court emphasized that such marketplace realities are often critical to the confusion analysis.

Citing A&H Sportswear, Inc. v. Victoria’s Secret Stores, Inc., 237 F.3d 198 (3d Cir. 2000), the court observed that the likelihood of confusion is typically a fact-intensive question best left to the jury when the evidence allows more than one reasonable inference. Because the parties presented competing interpretations of several Lapp factors—including similarity, strength, and evidence of confusion—the court determined that a factfinder must resolve the issue at trial.

Outcome. Having found genuine disputes of material fact on abandonment, judicial estoppel, and likelihood of confusion, the court denied Game Show Network’s motion for summary judgment.

The Case is No. 1:23-cv-00032-JHS.
