Case Timeline

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

U.S. Patent No. 8,792,874 - "System, Methods, Circuits And Associated Software For Augmenting Contact Details Stored On A Communication Device With Data Relating To The Contact Contained On Social Networking Sites"

• Issued: July 29, 2014

The Invention Explained

• Problem Addressed: The patent describes a technical environment where mobile social networking applications operate independently from a mobile device’s other communication functions, failing to leverage data from social networks to "improve the other communication functions performed by the mobile device" (’874 Patent, col. 2:65-68). This separation makes accessing value-added services "difficult and cumbersome" (’874 Patent, col. 2:53-54).
• The Patented Solution: The invention proposes a system on a mobile device featuring a "synchronization engine" that links a user’s local contacts with their corresponding profiles on social networking sites (SNS) (’874 Patent, Abstract). This engine, through "SNS adapters," retrieves data from various social networks, correlates it to contacts stored locally on the phone, and a "presentation and operation module" then displays this SNS-derived data in conjunction with the local contact information (’874 Patent, col. 10:50-65; Fig. 9A).
• Technical Importance: The described technology aims to provide deeper integration of social media data into the core user experience of a mobile phone, moving beyond siloed, stand-alone applications.

Key Claims at a Glance

• The complaint asserts claims 1-20 (Compl. ¶9). The independent claims are 1 (a mobile phone system) and 11 (a method).
• Independent Claim 1 (System): The key elements are:
  • A local memory for storing contacts
  • A "synchronization engine" adapted to correlate a local contact with an SNS profile, retrieve data from that profile, and associate the retrieved data with the local contact
  • A "presentation and operation module" adapted to display the retrieved data in association with the first contact on the mobile phone's user interface
• Independent Claim 11 (Method): The key steps are:
  • Correlating a first SNS profile with a first contact stored in local memory
  • Retrieving data from the SNS profile
  • Associating the retrieved data with the first contact
  • Displaying the retrieved data in association with the first contact on the mobile phone's user interface
• The complaint reserves the right to assert the remaining dependent claims (Compl. ¶9).

III. The Accused Instrumentality

Product Identification

The accused instrumentality is the WeChat application and its associated systems and services (Compl. ¶Intro).

Functionality and Market Context

The complaint alleges that WeChat provides services for "augmenting contact details stored on a mobile device" (Compl. ¶9). It does not, however, provide specific technical details about how the WeChat application performs this function, such as whether it interacts with the native phonebook or operates exclusively within its own application environment.

IV. Analysis of Infringement Allegations

The complaint states that support for the infringement allegations is found in a chart attached as Exhibit B (Compl. ¶10). This exhibit was not filed with the complaint and is not publicly available. Therefore, a claim chart summary cannot be constructed.

The complaint’s narrative infringement theory is that Defendant "maintains, operates, and administers systems, products, and services of augmenting contact details stored on a mobile device that infringe, directly and indirectly...one or more claims of the ‘874 patent" (Compl. ¶9). No probative visual evidence provided in complaint.

Identified Points of Contention

• Technical Questions: A primary question will be evidentiary: what proof will Plaintiff provide to demonstrate that the WeChat application’s software architecture performs the specific steps of "correlating," "retrieving," "associating," and "displaying" data as recited in the claims? The complaint does not offer specific facts on the operational mechanism of the accused product.
• Scope Questions: The analysis may focus on whether functionality contained entirely within the WeChat application—as opposed to integration with the phone’s native contact list or call screen—falls within the scope of the claims. The patent’s stated purpose of improving "the other communication functions performed by the mobile device" raises the question of whether such integration is a required element (’874 Patent, col. 2:67-68).

V. Key Claim Terms for Construction

Term: "synchronization engine"

• Context and Importance: This term recites the core functional component of the claimed invention. Its construction will be critical for determining what type of software architecture can be found to infringe, as the dispute will likely involve whether WeChat's architecture includes a component that meets this definition.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification describes the engine as software "adapted to reside on the operating memory of a communication device" that collects, displays, and integrates data, which could be argued to encompass any software module performing these functions, regardless of its specific implementation (’874 Patent, col. 10:58-68).
  • Evidence for a Narrower Interpretation: Figure 9A depicts the "Synchronization Engine" as a discrete software block that communicates with other specific modules like "SNS Adapters" and the "Communication Device Database." This could support a narrower construction requiring a specific modular architecture (’874 Patent, Fig. 9A).

Term: "in association with the first contact"

• Context and Importance: This phrase defines the required relationship between the retrieved SNS data and the contact stored in the phone's local memory. Practitioners may focus on this term because its interpretation will determine whether infringement requires displaying data on the phone's native contact screen or if a display within the accused app's own contact list is sufficient.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The language itself could be argued to require only a logical connection, where the SNS data is displayed at the same time and on the same screen as the contact's name, regardless of the underlying application.
  • Evidence for a Narrower Interpretation: The patent’s objective to "improve the other communication functions performed by the mobile device" and its description of displaying data "when the contact details are displayed" could be argued to imply an integration with the phone's native systems, not just a display within a self-contained third-party application (’874 Patent, col. 2:67-68, col. 11:10-12).

VI. Other Allegations

Indirect Infringement

The complaint alleges both induced and contributory infringement, stating that Defendant "actively encouraged or instructed others" to use its products in an infringing manner (Compl. ¶¶ 11-12). These allegations are conclusory and are not supported by specific factual assertions, such as citations to user manuals or marketing materials.

Willful Infringement

The complaint alleges that Defendant has known of the ’874 patent "from the date of issuance of the patent" and seeks treble damages (Compl. ¶¶ 11-12, Prayer for Relief ¶e). The complaint does not provide a specific factual basis for this allegation of pre-suit knowledge.

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

1. A central issue will be one of claim scope and technical implementation: Can the phrase "in association with the first contact," when read in light of the patent's specification, be construed to cover a scenario where social media data is displayed only within the confines of the third-party WeChat application, or does it require integration with the mobile device’s native contact list or other core communication functions?

2. The case will also turn on a key evidentiary question: Given the high-level nature of the complaint, what specific evidence will Plaintiff present to map the elements of the asserted claims—particularly the "synchronization engine" and its functions of "correlating," "retrieving," and "associating"—onto the actual architecture and operation of the WeChat application?
