IP Law Daily, PATENT—D. Del.: Comcast Cable secures dismissal of most infringement claims in dispute over streaming technology patents, (Jun 26, 2026)

By Mandavi Singh, LL.M.

The patent owner failed to plausibly allege joint infringement of three patents, and only one patent survived dismissal based on sufficiently pleaded direction-and-control allegations.

The federal district court in Wilmington, Delaware, has granted in part and denied in part Comcast's motion to dismiss an infringement lawsuit brought by an Irish licensing entity. The court dismissed, with prejudice, the plaintiff's direct, induced, and willful infringement claims relating to three asserted patents after finding that the complaint failed to plausibly allege that Comcast directed or controlled Amazon Web Services in performing the claimed methods. However, the court allowed the plaintiff's joint infringement claim involving a fourth patent directed to partial video pre-fetch technology to proceed, concluding that the complaint plausibly alleged that Comcast conditioned users' access to its streaming services on performing the claimed method. The court also dismissed the plaintiff's induced infringement claim for the surviving patent without prejudice because the plaintiff voluntarily withdrew it and dismissed its willful infringement claim against Comcast while granting leave to amend (Tir Technologies Limited v. Comcast Cable Communications, LLC, No. 1:25-cv-00885-JCG (D. Del. Jun. 24, 2026)).

Background. The plaintiff, Tir Technologies Ltd., is an Irish company that owns patents relating to network monitoring and video-streaming technologies. The defendants, Comcast Cable Communications, LLC and related entities, provide cable television, broadband internet, media and entertainment, and video-streaming services.

The dispute involved U.S. Patent Nos. 8,792,347 (the ’347 patent), 9,800,633 (the ’633 patent), 10,484,442 (the ’442 patent), and 10,375,444 (the ’444 patent). Collectively, the patents concern technologies for content delivery networks (CDNs), distributed video caching, and streaming media. Tir alleged that Comcast's streaming platforms, Xfinity Stream and Peacock, infringed the asserted patents by using multiple CDNs, including Amazon Web Services.

Tir filed suit in July 2025, alleging direct, induced, and willful infringement. After the court dismissed an amended complaint in March 2026 and directed Tir to cure the identified deficiencies, Tir filed a second amended complaint. Comcast again moved to dismiss, arguing that Tir still failed to plead direct infringement adequately, failed to establish joint infringement through Amazon Web Services or end users, improperly reasserted induced infringement claims, and inadequately pleaded willful infringement.

Joint infringement of the ’347, ’633, and ’442 patents. The principal issue concerned Tir's theory that Amazon Web Services performed certain claim steps under Comcast's direction or control. Citing Akamai Technologies, Inc. v. Limelight Networks, Inc., 797 F.3d 1020 (Fed. Cir. 2015), and Lyda v. CBS Corp., 838 F.3d 1331 (Fed. Cir. 2016), the court noted that a plaintiff alleging divided infringement must plausibly plead that one party directs or controls another's performance of the claimed method.

The court found that Tir failed to satisfy that standard. Although the complaint alleged "upon information and belief" that Comcast had contracted with Amazon Web Services through a private pricing agreement, the only supporting factual allegation was an Amazon webpage generally describing pricing models available to customers. The webpage did not mention Comcast or identify any contractual relationship between the parties. The court held that such allegations established only a "sheer possibility" of direction and control, not the plausible factual basis required by Ashcroft v. Iqbal and Bell Atlantic Corp. v. Twombly.

The court further observed that Tir had already amended its complaint multiple times without curing the same deficiencies. Finding further amendment would be futile and prejudicial, it dismissed with prejudice all direct, induced, and willful infringement claims relating to the ’347, ’633, and ’442 patents.

’444 patent. Unlike the other patents, Tir alleged that Comcast's client application software required end users to perform the claimed pre-fetching method to receive the benefits of Xfinity Stream and Peacock. According to the complaint, users could access streaming services only by employing Comcast's application code, which dictated the manner and timing of the claimed steps.

Accepting those allegations as true at the pleading stage, the court concluded that Tir had plausibly alleged that Comcast conditioned users' receipt of streaming benefits upon performance of the patented method, satisfying the standard articulated in Akamai. Citing Nalco Co. v. Chem-Mod, LLC, 883 F.3d 1337 (Fed. Cir. 2018), the court held that the allegations created a reasonable expectation that discovery could reveal evidence supporting the claim. Accordingly, it denied Comcast's motion to dismiss the direct infringement claim relating to the ’444 patent.

Prosecution history. Further, Comcast contended that Tir's infringement allegations conflicted with statements made during prosecution of the ’444 patent. During prosecution, the applicant distinguished prior art by explaining that the claimed invention stored only an initial pre-fetch portion of a media file locally before streaming the remaining portions from an origin server. Comcast contended that Tir's claim charts instead described local storage of multiple media segments, thereby recapturing subject matter surrendered during prosecution.

The court declined to dismiss the claim on that basis. Reading the complaint in the light most favorable to Tir, it concluded that the claim charts could reasonably be interpreted as referring to initial portions of different media files rather than multiple segments of a single file. Because the allegations did not clearly contradict the prosecution history, the court held that dismissal was inappropriate before discovery.

Induced and willful infringement. Tir agreed to withdraw its induced infringement claim relating to the ’444 patent, and the court dismissed that claim without prejudice. The court also dismissed Tir's willful infringement claim against Comcast. Although an original complaint can provide sufficient notice to support a post-suit willfulness claim, the court found that Tir's original pleading failed to adequately explain how Comcast's accused products infringed the ’444 patent. Consequently, Comcast lacked sufficient notice that its conduct allegedly constituted infringement. Nevertheless, because the direct infringement claim survived, the court granted Tir leave to amend its willful infringement allegations relating to the ’444 patent.

The Case is No. 1:25-cv-00885-JCG.
