Case Timeline

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: In an age of "Big Data," users are faced with information overload from sources like social network feeds, emails, and large collections of personal files, making it difficult to discern valuable information from irrelevant data (ʼ131 Patent, col. 1:19-42).
• The Patented Solution: The invention provides a computer-implemented method where a user can specify or the system can determine a "relevance criterion" and an associated "importance value" for electronic objects (e.g., files, contacts). The system receives this user-defined, non-binary importance value and then determines a display position for the object based directly on that value, allowing for a granular sorting of information beyond simple binary (important/not important) marking ('131 Patent, Abstract; col. 8:7-13; col. 17:36-40). The system can then display objects with different relevance in distinct, concurrently visible areas or with different visual effects ('131 Patent, col. 9:1-8).
• Technical Importance: The technical approach allows for a more nuanced, user-driven method of organizing large sets of data by moving beyond simple alphabetical or chronological sorting to a granular, value-based ranking system.

Key Claims at a Glance

• The complaint asserts infringement of one or more of claims 1-20 (Compl. ¶8). Independent claims are 1, 9, and 18.
• Independent Claim 1 (Method):
  • obtaining a plurality of electronic objects (e.g., existing files, folders, or contacts);
  • displaying the electronic objects in a user interface;
  • receiving an importance value associated with at least one object, where the value is a numerical value entered by a user, transformed from a user's text specification, or transformed from a user's selection of a UI object;
  • determining a position to place the object in the user interface directly from the importance value; and
  • placing the object in that determined position.
• The complaint reserves the right to assert all claims from 1-20, which would include dependent claims (Compl. ¶8, ¶10).

III. The Accused Instrumentality

Product Identification

The complaint does not name any specific L'Oreal product, service, or system (Compl. ¶8). It generally accuses "systems that facilitate organizing and structuring an unstructured collection of electronic objects" that L'Oreal "maintains, operates, and administers" (Compl. ¶8).

Functionality and Market Context

The complaint alleges that the accused systems perform methods of "organizing unstructured data sets by priority" (Compl. ¶10, ¶11). No further details regarding the specific functionality, operation, or market context of the accused instrumentalities are provided in the complaint.

No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint references an "Exhibit B" for detailed support of its infringement allegations but does not attach it (Compl. ¶9). The complaint’s narrative theory is that L'Oreal's systems for organizing electronic objects infringe the ’131 Patent (Compl. ¶8). It alleges that these systems organize "unstructured data sets by priority" (Compl. ¶10, ¶11). Without the specific allegations from Exhibit B or identification of an accused product, a detailed element-by-element analysis is not possible based on the complaint alone.

Identified Points of Contention

• Factual Question: A primary question will be a factual one: what specific L'Oreal systems are being accused, and what is their precise functionality? The complaint’s generalized description of "organizing and structuring an unstructured collection of electronic objects" provides little basis to assess infringement without more detail.
• Technical Question: Does any L'Oreal system actually "receiv[e] an importance value associated with at least one of the electronic objects" where that value is a non-binary, user-entered numerical value used "directly" to determine display position, as required by claim 1? The defense may argue that any sorting functionality in its systems (e.g., by date, price, or pre-set category) does not meet this specific limitation.

V. Key Claim Terms for Construction

The Term

"importance value"

Context and Importance

This term is central to every independent claim. Its construction will determine whether the patent covers only systems with explicit, granular, user-defined numerical rankings, or whether it can be read more broadly to cover other forms of sorting and prioritization common in e-commerce or data management systems. Practitioners may focus on this term to distinguish the claimed invention from conventional sorting methods.

Intrinsic Evidence for Interpretation

• Evidence for a Broader Interpretation: The specification suggests the value can be "transformed from a text specified by a user" (e.g., "medium" importance) or from selecting a UI object, which could support an argument that it is not strictly limited to direct numerical entry ('131 Patent, col. 17:49-56).
• Evidence for a Narrower Interpretation: Claim 1 requires the importance value to be, in part, a "non-binary numerical value" ('131 Patent, col. 18:14). The specification repeatedly provides examples of a user specifying a number on a scale (e.g., "8 on a scale of 1 to 10") or a specific numerical value (e.g., 0.8), suggesting the term requires a granular, quantitative input that is more specific than a simple categorical sort ('131 Patent, col. 11:40-44; col. 14:10-14).

VI. Other Allegations

Indirect Infringement

The complaint alleges both induced and contributory infringement. For inducement, it alleges L'Oreal "actively encouraged or instructed others (e.g., its customers...)" on how to use its products to perform infringing actions, such as "organizing unstructured data sets by priority" (Compl. ¶10). The contributory infringement allegation is substantively identical (Compl. ¶11).

Willful Infringement

The complaint alleges that L'Oreal has known of the ’131 Patent and the underlying technology "from at least the filing date of the lawsuit" (Compl. ¶10, ¶11). This appears to be a post-suit willfulness allegation, as no pre-suit knowledge is alleged.

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

1. A Threshold Evidentiary Question: The immediate issue is one of specificity. The complaint's failure to identify any accused L'Oreal product or provide the referenced infringement contentions in Exhibit B leaves the core of the dispute undefined. The first major hurdle for the plaintiff will be to articulate precisely which L'Oreal system infringes and how.
2. A Core Claim Scope Question: The case will likely turn on the definition of "importance value". Can this term, as defined and used in the patent, be construed to read on the functionality of commercial off-the-shelf or custom e-commerce and data management systems? The court's interpretation will determine whether standard sorting features (e.g., "sort by relevance" in a product search) fall within the scope of the claims, or if the claims are limited to specialized interfaces that allow users to assign specific, non-binary numerical weights to data objects.
3. A Functional Mismatch Question: A key factual dispute will be whether L'Oreal's systems "functionally match" the claims. The defense will likely argue that their systems do not "determin[e] a position... directly from the importance value" as claimed, but rather use complex, multi-factor algorithms for which a user's preference is only one of many inputs, thereby breaking the direct link required by the patent.
