Summary
The United States District Court for the District of Delaware granted Defendants’ Rule 12(b)(6) motion to dismiss Tir Technologies Ltd.’s claims for direct and joint infringement of four patents. The court held that the amended complaint did not adequately explain how Comcast’s content delivery network infringed the asserted patents or establish that Amazon’s alleged performance of claim steps was attributable to Defendants, while granting leave to amend.

Questions Presented
- Whether the amended complaint plausibly alleged direct infringement by the Comcast Defendants' content-delivery network under the Iqbal/Twombly pleading standard.
- Whether the amended complaint plausibly alleged joint infringement by connecting Amazon's performance of claim steps to Defendants through direction or control or a joint enterprise.
Holdings
- The amended complaint failed to state a plausible direct-infringement claim based on the Comcast Defendants' CDN because the claim charts explained Amazon's alleged infringement but did not separately provide factual allegations explaining how the Comcast CDN performed the claimed steps.
- The amended complaint failed to plausibly allege joint infringement because it did not plead facts showing that Amazon's performance of claim steps was attributable to Defendants through direction or control, and it did not allege a joint enterprise.
Key quotations
“Plaintiff’s repeated assertions regarding the knowledge of a hypothetical person of ordinary skill in the art are not factual allegations describing how Amazon’s products function similarly to the accused products, but are rather the type of “mere conclusory statements” that are insufficient to state a claim of infringement.” (Discussion I.A)
“The Court concludes that the Amended Complaint fails to allege specifically that Amazon’s products and services are under the direction and control of Defendants, such that the Court can draw a reasonable inference that the allegedly infringing performance of each claim step was attributable to Defendants.” (Discussion I.B)
Factual background
Tir Technologies, an Irish company and assignee of four U.S. patents concerning network monitoring and video delivery, accused Comcast, NBCUniversal, and Peacock of infringement through Xfinity Stream and PeacockTV services using Comcast and Amazon content-delivery networks. The amended complaint and accompanying claim charts described Amazon CloudFront functionality in detail but generally asserted that a person of ordinary skill would understand Comcast's CDN to operate similarly. Tir Technologies also alleged that Defendants orchestrated infringement by customers, end users, and CDN providers, without alleging facts showing that Amazon was under Defendants' direction or control.
Procedural history
Tir Technologies filed the action in July 2025, alleging direct and induced infringement of four patents. After Defendants' initial motion became moot upon filing of the amended complaint, Defendants moved to dismiss the amended complaint on November 26, 2025. Following oral argument on February 19, 2026, the court granted dismissal with leave to amend by March 25, 2026.
