II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 8,904,464 - "Method For Tagging An Electronic Media Work To Perform An Action"
- Patent Identification: U.S. Patent No. 8,904,464, issued December 2, 2014 (’464 Patent).
The Invention Explained
- Problem Addressed: The patent describes the difficulty in linking media works (e.g., television commercials) to interactive content (e.g., websites) using prior art methods. These older techniques required embedding an active signal, such as a watermark or code in the vertical blanking interval, directly into the media work. This process of modifying the original content was described as creating logistical, legal, and quality control problems ('464 Patent, col. 3:5-20). The patent identifies an unmet need for a method of identifying a work without altering the original signal ('464 Patent, col. 3:17-23).
- The Patented Solution: The invention solves this problem by analyzing the content of the media work itself. It proposes a system that extracts inherent features from a work to create a compact, unique representation (a "feature vector"). This feature vector acts as a fingerprint that can be compared against a database of known feature vectors to find a match and retrieve a corresponding "work identifier." This identifier is then used to look up associated information, such as a URL or instructions for an e-commerce transaction, which can be provided to the user ('464 Patent, Abstract; Fig. 1). The system does not require any modification to the original media work ('464 Patent, col. 5:26-30).
- Technical Importance: This passive, content-based identification approach enables automated linking of content to data at a massive scale without requiring the cooperation of content creators to embed proprietary signals into their works ('464 Patent, col. 1:53-61).
Key Claims at a Glance
- The complaint asserts "one or more claims of the ’464 patent, including but not limited to claim 18" (Compl. ¶28).
- Independent Claim 18 recites a computer-implemented method comprising the essential elements of:
- receiving associated information for an action to be performed in association with a media work identifier;
- receiving an electronic media work;
- correlating the media work with its identifier using a "non-exhaustive, near neighbor search";
- storing the resulting correlation information;
- generating a "tag" associated with the media work;
- providing the media work and the tag to a user's device;
- receiving a request from the user's device related to the tag;
- generating machine-readable instructions for the action based on the associated information; and
- providing those instructions to the user's device.
- The complaint’s reference to claims "including but not limited to" claim 18 suggests a reservation of the right to assert other claims, including dependent claims.
III. The Accused Instrumentality
Product Identification
- The accused instrumentalities are the "YouTube site" (referring to www.youtube.com and m.youtube.com) and the "Content ID system" operated by Defendants (Compl. ¶¶18, 27).
Functionality and Market Context
- The complaint alleges that the YouTube site allows users to upload electronic media works (video content) and delivers these works to other users (Compl. ¶19).
- The Content ID system is described as a system that maintains databases of "electronic media work identifiers" for more than 25 million reference files (Compl. ¶20). When a user uploads a video, the system is alleged to correlate it with a known identifier using a "non-exhaustive near neighbor search" (Compl. ¶21).
- Following this correlation, the system allegedly generates an associated "tag," provides the media work and tag to a user, and then processes user requests related to that tag to generate and provide instructions for performing an action (Compl. ¶22).
- The complaint asserts that the YouTube site is the "top online video content property on the Internet" and that its Content ID system is a key part of a business that has paid over $1 billion to rightsholders (Compl. ¶23).

Identified Points of Contention
- Technical Questions: A central evidentiary question is whether YouTube's Content ID system actually performs a "non-exhaustive, near neighbor search" as claimed. The complaint alleges this on "information and belief" (Compl. ¶21), and the specific nature of Google's proprietary matching algorithm will be a primary focus of discovery.
- Scope Questions: The complaint alleges the generation and provision of a "tag" (Compl. ¶22). A dispute may arise over what constitutes a "tag" under the patent's claims. The question will be whether any metadata, hyperlink, or other information provided on the YouTube page alongside a video meets the definition and function of the "tag" as recited in the claim, which is provided from the computer system to the user device along with the media work.
V. Key Claim Terms for Construction
The Term: "non-exhaustive, near neighbor search"
- Context and Importance: This term describes the core technical mechanism for matching content. The infringement case hinges on whether the algorithm used by Google's Content ID falls within this definition. Practitioners may focus on this term because it is not a generic term for "matching" but refers to a specific class of search algorithms known in computer science.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification describes this as a type of "sub-linear time search" and explicitly provides "an approximate nearest neighbor search" as an example, suggesting it is a category of algorithm rather than one specific method ('464 Patent, col. 4:3-9).
- Evidence for a Narrower Interpretation: The specification also references specific, technical examples of such search methods, including "kd-trees, vantage point trees and excluded middle vantage point forests" ('464 Patent, col. 8:60-63). A party could argue that the term's scope is limited by these examples, particularly if they were used to distinguish the invention from prior art.
The Term: "tag"
- Context and Importance: Claim 18 requires generating a "tag" and "providing" it with the media work to a user's device. The viability of the infringement theory depends on identifying a corresponding data element in the accused system that is provided to the end-user.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent's abstract describes a tag as being "associated with the media work having a media work identifier," which could be interpreted broadly to mean any data structure or metadata that links the content to its identifier for the purpose of enabling a future action ('464 Patent, Abstract).
- Evidence for a Narrower Interpretation: Claim 18 recites "providing... the first electronic media work and the tag" as if they are two distinct items being sent to the user device ('464 Patent, col. 26:3-5). This could support an argument that the "tag" must be a discrete data object, not merely information embedded in a webpage, and that it must be provided in the same transaction as the media work itself.
VI. Other Allegations
Indirect Infringement
- The complaint does not plead specific facts to support claims for indirect (induced or contributory) infringement, focusing instead on allegations of direct infringement by Defendants' systems (Compl. ¶28).
Willful Infringement
- The complaint does not use the word "willful" but requests "treble damages pursuant to 35 U.S.C. § 284" (Compl., Prayer for Relief ¶3). The factual basis for this request appears to be alleged pre-suit knowledge of the technology, based on the allegation that Defendants have cited the inventor's patents as prior art in their own patent applications (Compl. ¶17).
VII. Analyst’s Conclusion: Key Questions for the Case
A key evidentiary question will be one of technical implementation: Does the algorithm at the core of Google’s Content ID system meet the claim requirement of a “non-exhaustive, near neighbor search”? The outcome will depend on evidence obtained during discovery regarding the specific design and operation of Google’s proprietary technology.
A central legal issue will be one of definitional scope: How should the term "tag" be construed? The dispute will likely focus on whether it requires a discrete data element transmitted to the user's device alongside the media work, or if it can be interpreted more broadly to cover hyperlinks or other actionable information presented on the YouTube webpage.
The case will also present a question of procedural estoppel: Given that the asserted patent claims were confirmed as patentable in a CBM post-grant review proceeding that likely involved the Defendant, to what extent are Defendants now limited in their ability to raise invalidity defenses, particularly those based on prior art that was or could have been raised in that proceeding?
