Err Content IP LLC v. fuboTV Inc

I. Executive Summary and Procedural Information

• Parties & Counsel:
  • Plaintiff: ERR Content IP, LLC (Delaware)
  • Defendant: FuboTV, Inc. (Delaware)
  • Plaintiff's Counsel: David J. Hoffman
• Case Identification: 1:26-cv-02230, S.D.N.Y., 03/18/2026
• Venue Allegations: Plaintiff alleges venue is proper in the Southern District of New York because Defendant has a regular and established place of business in the district, including an office at 1290 Avenue of the Americas, and has committed acts of infringement there.
• Core Dispute: Plaintiff alleges that Defendant's FuboTV streaming application and related systems infringe a patent related to methods for providing a main content stream to a first device while providing corresponding, synchronized "extra content" to a second device.
• Technical Context: The technology at issue addresses the "second screen" phenomenon, where viewers use a secondary device like a smartphone or tablet to access supplemental information related to the primary content they are watching on a television.
• Key Procedural History: The complaint states that Plaintiff is a non-practicing entity and that it and its predecessors-in-interest have entered into settlement licenses with other entities, though it asserts none of these licenses were for the production of a patented article that would trigger marking requirements under 35 U.S.C. § 287.

Case Timeline

II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 10,721,542 - "Method and device for providing a main content and an extra content to a user through reference item"

• Patent Identification: U.S. Patent No. 10,721,542, "Method and device for providing a main content and an extra content to a user through reference item," issued July 21, 2020.

The Invention Explained

• Problem Addressed: The patent describes a limitation in then-current systems where a user who wants to access additional information related to a broadcast must "leave the main content" to do so, forcing a choice between the primary program and the supplemental data '542 Patent, col. 1:36-39
• The Patented Solution: The invention proposes a method where a first device (e.g., a TV) receives and displays a "main content" (e.g., a video stream) that is broadcast together with "metadata" from a first source '542 Patent, col. 2:22-38 This metadata is then forwarded to a second device (e.g., a smartphone), which uses the metadata to retrieve "extra content" from a different, second source and display it '542 Patent, col. 2:31-38 This allows the user to view the main content on the first device and simultaneously view related, synchronized extra content on the second device '542 Patent, abstract
• Technical Importance: This technological approach facilitates an interactive, multi-device viewing experience, often called a "second screen" experience, which became a significant feature in digital media consumption.

Key Claims at a Glance

• The complaint asserts at least independent claim 1 and reserves the right to assert additional claims Compl. ¶17 Compl. ¶¶23-24
• Essential elements of independent claim 1 include:
  • Receiving a specific main content and metadata from a first source and displaying the main content on a first device.
  • The metadata and main content are broadcast together from the first source, and the metadata links the main content with an extra content.
  • Forwarding the metadata to a second device.
  • The forwarding is executed by "scanning said metadata by said second device."
  • The second device receives the extra content from a second source.
  • The main content is displayed on the first device while the extra content is displayed on the second device.
  • The extra content changes in correspondence to a change of the specific main content.
  • The first and second sources are different.

III. The Accused Instrumentality

Product Identification

• The "FuboTV app system and related systems" Compl. ¶15

Functionality and Market Context

• The complaint identifies the accused functionality by referencing a FuboTV support article titled "How-do-I-cast-Fubo-using-Chromecast/" Compl. ¶15 Compl. ¶23 This suggests the accused method involves a user operating the FuboTV application on a device like a smartphone (the second device) to select and transmit a video stream (the main content) to a separate display device like a television connected to a Chromecast (the first device). While the main content plays on the television, the user can continue to interact with the FuboTV application on their smartphone, which may display related content.
• FuboTV is a live TV streaming service, positioning itself in the market as a "cable-TV replacement" with a focus on live sports.

IV. Analysis of Infringement Allegations

The complaint references a claim chart (Exhibit B) that was not publicly filed with the pleading Compl. ¶22 The infringement theory must therefore be inferred from the narrative allegations. The core allegation appears to be that the FuboTV system's "casting" feature meets the elements of claim 1. A user's phone running the FuboTV app acts as the "second device," while the television with a Chromecast acts as the "first device." The phone forwards instructions ("metadata") to the Chromecast to retrieve and play a video stream ("main content"). Simultaneously, the phone's app screen displays other information ("extra content").

No probative visual evidence provided in complaint.

Identified Points of Contention

• Scope Questions: A central dispute may arise over the meaning of "forwarding of said metadata is executed by scanning said metadata by said second device" '542 Patent, cl. 1 The complaint does not explain how initiating a "cast" from a software application constitutes "scanning." This raises the question of whether "scanning" is limited to the optical methods described in the patent's specification (e.g., QR codes) or can be interpreted to cover the electronic transmission of data initiated by a user interface command.
• Technical Questions: The complaint does not specify what constitutes the claimed "metadata" or the "extra content" in the FuboTV system. A key evidentiary question will be whether the accused system forwards metadata that explicitly "links said specific main content with an extra content," as the claim requires, or merely forwards a URL for the video stream. Further, it raises the question of what evidence shows that the "extra content" displayed on the FuboTV app changes "in correspondence to a change of the specific main content" being played on the television.

V. Key Claim Terms for Construction

• The Term: "scanning said metadata by said second device"
• Context and Importance: The viability of the infringement case may depend heavily on the construction of this term. Defendant will likely argue for a narrow construction limited to optical scanning, which the accused "casting" functionality may not perform. Plaintiff would need to argue for a broader construction that encompasses electronic data capture initiated by a user. Practitioners may focus on this term because it appears to be the element least obviously met by a standard video casting function.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language itself does not explicitly state "optical scanning." A party might argue that in the context of a computing device, "scanning" can refer to reading or processing any data source, not just a visual one.
  • Evidence for a Narrower Interpretation: The patent specification provides specific examples of scanning, such as using "QR-codes, bar codes or optical machine-readable data" '542 Patent, col. 3:58-64 The description of a separate embodiment where "said forwarding of said reference item is executed by scanning said reference item by means of said second device" further grounds the term in a physical or optical action '542 Patent, col. 5:40-44

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement Compl. ¶¶23-24 Inducement is based on allegations that FuboTV actively encourages and instructs its customers on how to use the accused casting features, citing a support article as evidence Compl. ¶23 Contributory infringement is alleged on the basis that there are "no substantial noninfringing uses" for the accused products and services Compl. ¶24
• Willful Infringement: Willfulness is based on alleged knowledge of the '542 Patent "from at least the filing date of the lawsuit" Compl. ¶23 Compl. ¶24 The complaint does not allege pre-suit knowledge.

VII. Analyst's Conclusion: Key Questions for the Case

• A core issue will be one of definitional scope: can the term "scanning," which the patent specification exemplifies with optical QR codes, be construed broadly enough to cover the electronic act of a user initiating a "cast" of a video stream from a software application?
• A second key issue will be one of evidentiary proof: what specific technical evidence will demonstrate that the FuboTV system uses "metadata" that links main and extra content, and that the "extra content" on the user's mobile device dynamically changes in direct correspondence with the video playing on the television, as required by the claim? The complaint's lack of detail on this point suggests it will be a central focus of discovery and expert analysis.
