• Core Dispute: Plaintiff alleges that Defendant’s unspecified products infringe a patent related to systems for communicating a user's status via a graphical avatar.
• Technical Context: The technology at issue involves using an attribute of a communication device, such as a phone number, to select and display a corresponding avatar that conveys information about the device user's current activity or status.
• Key Procedural History: The patent-in-suit claims priority back to a 2003 Australian application and is the result of a long chain of U.S. continuation applications. The complaint does not mention any other significant procedural events.

Case Timeline

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

• Patent Identification: U.S. Patent No. 10,182,157, "Systems and methods for communicating," issued January 15, 2019.

The Invention Explained

• Problem Addressed: The patent background describes a need for mobile phone users to determine what another user is doing (e.g., in a meeting, traveling) without having to speak with them directly, and notes the inefficiency of SMS messaging for this purpose (ʼ157 Patent, col. 1:38-53).
• The Patented Solution: The invention provides a system where an "attribute" of a communication device (e.g., its phone number from caller ID data) is used to identify a corresponding "avatar" ('157 Patent, Abstract). This avatar, described as an image like a digital photograph or animated icon, conveys information about the user's current activity (e.g., an avatar depicting a person in a business suit to indicate they are at work) and is communicated to the other device ('157 Patent, col. 2:6-17). The system also contemplates replacing avatars to reflect changes in activity and presenting them within a "virtual environment" such as a virtual office (ʼ157 Patent, col. 2:18-21; col. 3:3-14).
• Technical Importance: The described solution aims to improve the efficiency of communication by providing non-verbal, real-time status updates between users of communication devices ('157 Patent, col. 1:36-44).

Key Claims at a Glance

• The complaint does not identify any specific claims of the ’157 Patent asserted against the Defendant (Compl. ¶11, ¶13). It states that "Exemplary '157 Patent Claims" are identified in an Exhibit 2, which was not filed with the complaint (Compl. ¶13).

III. The Accused Instrumentality

Product Identification

• The complaint does not identify any accused products, methods, or services by name (Compl. ¶11). It refers generally to "Exemplary Defendant Products" that are purportedly identified in the missing Exhibit 2 (Compl. ¶11, ¶13).

Functionality and Market Context

• The complaint does not provide sufficient detail for analysis of the accused instrumentality's functionality or market context.

IV. Analysis of Infringement Allegations

The complaint alleges that Defendant directly infringed one or more claims of the ’157 Patent by "making, using, offering to sell, selling and/or importing" the unidentified "Exemplary Defendant Products" (Compl. ¶11). It further alleges that Defendant’s employees directly infringed by internally testing and using these products (Compl. ¶12). The complaint states that claim charts comparing the asserted claims to the accused products are contained in Exhibit 2; however, this exhibit was not provided with the complaint (Compl. ¶13). The complaint asserts narratively that the "Exemplary Defendant Products practice the technology claimed by the '157 Patent" and "satisfy all elements of the Exemplary '157 Patent Claims" (Compl. ¶13). No probative visual evidence provided in complaint.

Due to the absence of specific asserted claims and any description of the accused products in the complaint, an analysis of potential points of contention cannot be performed.

V. Key Claim Terms for Construction

The complaint does not identify specific asserted claims, precluding an analysis of key terms for construction.

VI. Other Allegations

• Indirect Infringement: The complaint makes no allegations of indirect infringement.
• Willful Infringement: The complaint makes no allegations of willful infringement. The prayer for relief requests a declaration that the case is "exceptional" for the purpose of awarding attorneys' fees under 35 U.S.C. § 285, but does not plead facts to support a claim for willfulness or enhanced damages under § 284 (Compl. p. 4).

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

Based on the initial pleading, the case appears to present several foundational questions before substantive technical disputes can be addressed.

• Pleading Sufficiency: A primary issue may be whether the complaint provides sufficient notice of the infringement allegations. The failure to identify any specific asserted claims or accused products in the body of the complaint, relying instead on a missing exhibit, raises a threshold question about whether the pleading meets the standards set forth by the Federal Rules of Civil Procedure.
• Definitional Scope: Assuming the claims and products are identified, a central dispute will likely concern the scope of key claim terms. For instance, the case may turn on whether a modern messaging application's status indicator or profile picture functionality can be construed to meet the patent's specific claim limitations for an "avatar" that is identified and communicated based on a "communication device identifier."
• Technical Implementation: An evidentiary question will likely be one of technical operation. The case may focus on whether the accused products perform the specific steps of the asserted claims, such as storing "activity information" in a "storage device" and allowing access "based on finding a match between the stored identifying information and identification data of the communication device," as recited in independent claim 1 of the patent.
