Case Timeline

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

U.S. Patent No. 9,092,428: “System, methods and user interface for discovering and presenting information in text content” (Issued Jul. 28, 2015)

The Invention Explained

• Problem Addressed: The patent addresses the problem of "information overload," where users struggle to find specific, relevant information within large volumes of unstructured text, such as numerous online hotel reviews or lengthy medical documents (Compl. ¶9; ’428 Patent, col. 1:13-21). For example, a user may want to find only the negative comments about a hotel's room service without reading hundreds of reviews (’428 Patent, col. 1:21-39).
• The Patented Solution: The invention is a computer-assisted system that analyzes text to associate "grammatical, semantic, and contextual attributes" with words or phrases (’428 Patent, col. 3:19-22). It then provides user interface objects that allow a user to select a specific attribute (e.g., "positive opinion") and an action (e.g., "highlight" or "extract"). The system then performs this action on the corresponding text, presenting the filtered information in formats like a list, topic tree, or word cloud (’428 Patent, col. 3:25-34, Fig. 1).
• Technical Importance: The technology aimed to provide users with more sophisticated tools than simple keyword searching, enabling them to digest and analyze large text corpuses based on meaning and context, rather than just word matching (’428 Patent, col. 1:55-64).

Key Claims at a Glance

• The complaint asserts infringement of one or more of claims 1-20 (Compl. ¶10). Independent claim 1 is central.
• Independent Claim 1 requires:
  • Obtaining a text content comprising words or phrases.
  • Displaying a user interface for a user to select from a "first semantic attribute" and a "second semantic attribute".
  • Identifying words or phrases in the text associated with the selected attribute.
  • Displaying an "actionable user interface object" associated with a label representing the attribute.
  • Allowing the user to select the attribute via the interface object.
  • Performing an action (extracting, displaying, storing, showing, hiding, highlighting, or un-highlighting) on the identified words or phrases.
• The complaint reserves the right to assert dependent claims (Compl. ¶10).

III. The Accused Instrumentality

Product Identification

• The complaint does not identify a specific accused product or service by name. It accuses "a system with methods and user interface for discovering information in a text content and extracting and presenting the information" that Defendant "maintains, operates, and administers" (Compl. ¶10).

Functionality and Market Context

• The complaint alleges that Defendant, a watch company, puts into service "inventions claimed by the '428 Patent" (Compl. ¶10). However, it provides no details on how the accused system functions, what text it analyzes (e.g., customer reviews, product descriptions), or what user interface it presents. The complaint does not provide sufficient detail for analysis of the accused instrumentality's specific features or market context.

IV. Analysis of Infringement Allegations

The complaint references a "preliminary exemplary table attached as Exhibit B" to support its infringement allegations (Compl. ¶11). However, Exhibit B was not filed with the complaint. In its absence, the infringement theory must be inferred from the complaint's narrative allegations.

The core allegation is that Defendant operates a system that infringes claims 1-20 of the '428 patent by "discovering information in a text content and extracting and presenting the information" (Compl. ¶10, 12). This general statement mirrors the patent's overall purpose but lacks the specificity required to map system features to individual claim elements. The complaint does not describe what semantic attributes Defendant's system allegedly uses, what user interface objects it provides, or what specific actions it performs on text.

No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Instrumentality Identification: A primary issue will be identifying the specific system, service, or software operated by MVMT Watches, Inc. that is accused of infringement. The complaint's lack of specificity on this point raises a foundational question of notice and plausibility.
  • Technical Questions: Once an instrumentality is identified, a key question will be whether it actually performs the claimed functions. For example, does the accused system merely perform keyword filtering, or does it identify and act upon "semantic attributes" as required by the claims? What evidence demonstrates that the accused system associates attributes with text and provides distinct user interface objects for attribute selection and action, as claimed?

V. Key Claim Terms for Construction

• The Term: "semantic attribute"

• Context and Importance: This term is the core of the invention's filtering mechanism and appears in independent claim 1. Its construction will determine what types of information filtering fall within the patent's scope. The dispute will likely center on whether this term is limited to the specific examples in the patent (e.g., sentiment, topics) or covers any abstract data tag.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent describes attributes as potentially being "grammatical, semantic, contextual, or topical, etc." (’428 Patent, col. 6:8-9), suggesting a wide range of possible meanings beyond the specific examples.
  • Evidence for a Narrower Interpretation: The specification's detailed examples focus heavily on a specific type of semantic attribute: user "opinion" (e.g., positive, negative, or neutral) in product reviews (’428 Patent, col. 9:1-5). An argument could be made that the invention is directed at sentiment analysis, and the term should be construed in light of these prominent embodiments. The patent also provides other specific examples, such as "over-the-counter drug names" (’428 Patent, Fig. 2).

• The Term: "actionable user interface object"

• Context and Importance: This term from claim 1 defines the mechanism through which a user initiates the claimed action. Its construction is critical to determining what user interactions constitute infringement. Practitioners may focus on this term because the patent appears to distinguish between an object for selecting an attribute and an object for triggering an action.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The term "object" could be read broadly to encompass any interactive element on a screen, such as a hyperlink, a text field, or a selectable image.
  • Evidence for a Narrower Interpretation: The patent figures consistently depict discrete, labeled interface elements like buttons (e.g., "Extract Top 10 Important Terms," Fig. 3, 320) or dropdown menus (Fig. 7) as the actionable objects. The specification also describes an "attribute selector 160" and an "action selector 170" as distinct components, which could support an argument that the "actionable user interface object" must be a specific type of control separate from the content itself (’428 Patent, col. 6:5-15).

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement. The inducement allegation is based on the claim that Defendant "actively encouraged or instructed others (e.g., its customers...)" on how to use its products and services in an infringing manner (Compl. ¶12).
• Willful Infringement: Willfulness allegations are based on knowledge of the '428 patent "from at least the filing date of the lawsuit" (Compl. ¶12, 13). Plaintiff explicitly reserves the right to amend its complaint if discovery reveals evidence of pre-suit knowledge (Compl. p. 5, fn. 1, 2).

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

1. Instrumentality Identification: The immediate and most significant question is which specific product, website feature, or internal system of a watch company is being accused of infringing a patent on semantic text analysis. The resolution of this ambiguity is a prerequisite for any meaningful analysis of the infringement claims.
2. Definitional Scope: The case will likely turn on the construction of "semantic attribute". The central legal question is whether this term can be broadly interpreted to cover any form of data tagging or filtering, or if it is limited by the patent’s examples to more complex contextual concepts like user sentiment or domain-specific topics.
3. Evidentiary Sufficiency: Assuming an accused instrumentality is identified, a key evidentiary hurdle for the Plaintiff will be demonstrating a functional match to the claims. The critical question will be whether the accused system performs the specific two-step process recited in claim 1—first, allowing a user to select a "semantic attribute", and second, providing an "actionable user interface object" to perform an action based on that attribute—or if it operates through a simpler, non-infringing mechanism.
