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

U.S. Patent No. 9,430,131 - "System, Methods, And User Interface For Organizing Unstructured Data Objects"

• Patent Identification: U.S. Patent No. 9,430,131, "System, Methods, And User Interface For Organizing Unstructured Data Objects," issued August 30, 2016.

The Invention Explained

• Problem Addressed: The patent addresses the problem of "information overload" where users are presented with large, unstructured lists of data (e.g., social network feeds, search results, files, contacts) and find it difficult to discern relevant from irrelevant information. (’131 Patent, col. 1:19-35).
• The Patented Solution: The invention provides a method and system where users can assign a non-binary "importance value" to electronic objects. This value, which can be a number or transformed from a user interface selection, is then used to organize and display the objects, for instance by sorting them or placing them in different display areas to distinguish more important items from less important ones. (’131 Patent, col. 1:51-64; col. 2:5-15). The system is designed to go beyond simple binary "important/not important" flags to allow for more granular control. (’131 Patent, col. 14:26-39).
• Technical Importance: This approach aims to make information feeds and large data collections more manageable by allowing a user's subjective or contextual sense of relevance to directly influence the visual presentation of the data. (’131 Patent, col. 9:11-24).

Key Claims at a Glance

• The complaint asserts claims 1-20. (Compl. ¶9). Independent claim 1 is a method claim.
• Independent Claim 1:
  • obtaining a plurality of electronic objects (comprising existing files, folders, or contacts);
  • displaying the electronic objects or their names/icons in a user interface;
  • receiving an importance value associated with at least one object, where the value is entered by a user and can be a numerical value, or transformed from a text specification or a UI object selection;
  • determining a position to place the object in the user interface directly from the importance value; and
  • placing the electronic object or its name/icon in the determined position.
• The complaint reserves the right to assert all claims 1-20. (Compl. ¶9).

III. The Accused Instrumentality

Product Identification

• The complaint accuses unspecified "systems, products, and services that facilitate organizing and structing an unstructured collection of electronic objects." (Compl. ¶9).

Functionality and Market Context

• The complaint does not specify any particular product, website feature, or mobile application. It alleges in general terms that Defendant "maintains, operates, and administered systems" that perform infringing methods. (Compl. ¶9). The complaint's infringement theory appears to target Defendant's electronic commerce platforms more broadly. (Compl. ¶8). The complaint does not provide sufficient detail for analysis of the specific functionality of any accused instrumentality.

IV. Analysis of Infringement Allegations

The complaint references an "exemplary table included as Exhibit A" to support its infringement allegations but does not attach the exhibit. (Compl. ¶10). The complaint's narrative allegations are general, stating that Defendant's systems "facilitate organizing and structing an unstructured collection of electronic objects" in a way that infringes the ’131 patent. (Compl. ¶9). Without the specific mappings of claim elements to accused functionalities that would be contained in Exhibit A, a detailed infringement analysis is not possible from the pleading alone.

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

• The Term: "importance value"
• Context and Importance: This term is the core of the invention. Its scope will be critical to determining infringement, as the dispute will likely center on whether features in the accused systems (e.g., sorting by "relevance," "best-selling," or "top-rated") constitute a user-entered "importance value" as claimed. Practitioners may focus on this term because its definition dictates whether a wide range of common e-commerce sorting and filtering functions fall within the patent's scope.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The claim language itself is broad, defining the value as something "entered by a user" that can be "a numerical value directly entered by a user, a numerical value transformed from a text specified by a user, [or] a numerical value transformed from a selection of a user interface object indicated by a user." (’131 Patent, col. 23:39-44). This suggests any user action that results in a ranked or prioritized display could be construed as providing an "importance value."
  • Evidence for a Narrower Interpretation: The specification repeatedly provides examples where the user explicitly assigns a granular, numerical score (e.g., "on a 0 to 1 scale" or from a list of values) to a specific criterion or object. (’131 Patent, col. 11:36-40, Fig. 2A, Fig. 9). This may support a narrower construction requiring a more direct and explicit assignment of a specific value by the user, rather than merely selecting a pre-defined sorting option like "sort by popularity."

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement. For inducement, it alleges Defendant encourages and instructs customers on how to use its services (e.g., "organizing unstructured data sets by priority") to cause infringement. (Compl. ¶11). For contributory infringement, it makes a conclusory allegation that there are no substantial non-infringing uses for the accused products and services. (Compl. ¶12).
• Willful Infringement: The complaint does not plead pre-suit knowledge. It alleges Defendant has known of the ’131 patent "from at least the filing date of the lawsuit," which would support a claim for post-filing willfulness only. (Compl. ¶11-12). The complaint reserves the right to amend if discovery reveals an earlier date of knowledge. (Compl. p. 4, n.1-2).

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

1. Evidentiary Sufficiency: The primary initial question is one of pleading adequacy. Can the plaintiff's highly general allegations survive a motion to dismiss, given the absence of specific accused product identification and the failure to include the referenced "Exhibit A" claim chart?
2. Definitional Scope: A core substantive issue will be one of claim construction. Can the term "receiving an importance value...entered by a user" be construed to cover standard e-commerce sorting options (e.g., "sort by price," "sort by rating"), or does it require a more specific, user-defined, granular input as depicted in the patent's detailed embodiments?
3. Obviousness and Prior Art: The case may also raise a significant validity question. Given the patent's 2013 priority date, a key issue will be whether the claimed method of organizing data based on user-defined importance was obvious in light of the numerous sorting, filtering, and personalization features prevalent in web applications and search engines at the time.
