Case Timeline

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

U.S. Patent No. 7,899,479 - "METHOD, SYSTEM AND APPARATUSES FOR SHARING PRESENCE INFORMATION," issued March 1, 2011

The Invention Explained

• Problem Addressed: In conventional group communication systems, if a user wants to know the status (i.e., "presence information") of all other members in a group, that user must individually request the information for each member one by one. The patent describes this process as "lengthy and inconvenient" (’479 Patent, col. 2:1-4).
• The Patented Solution: The invention proposes a more efficient, centralized method. A system entity—such as a "group server," a "presence server," or a dedicated "presence information management apparatus"—is responsible for acquiring both static "basic group information" (e.g., the member list) and dynamic "presence information" (e.g., a member's online status) (’479 Patent, col. 4:1-20). This entity then combines these two data types into "group presence information" and sends the consolidated information to a group member, typically upon receiving a subscription request (’479 Patent, col. 4:46-58). Figure 5 of the patent illustrates a process flow where a group server subscribes to member presence information from a presence server (step 503), combines it with basic group data (step 505), and notifies a group member of the combined information (step 507).
• Technical Importance: This approach automates and centralizes the aggregation of presence data, intended to simplify the user experience and reduce network traffic compared to a system requiring numerous individual client-to-server requests for the same information (’479 Patent, col. 2:60-68).

Key Claims at a Glance

• Independent Claim Asserted: Claim 1 (Compl. ¶14).
• Essential Elements of Claim 1:
  • A method for sharing presence information, comprising:
  • acquiring, by one of a group server, a presence server and a presence information management apparatus connected to the group server and the presence server, group presence information;
  • the group presence information comprises basic group information and presence information of at least one group member in a group provided by the group server;
  • the basic group information is from the group server and comprises a group attribute, a group member list and a group member attribute;
  • the presence information of at least one group member is from the presence server; and
  • sending, by the one of the group server, the presence server and the presence information management apparatus, the group presence information to a group member.
• The complaint also asserts dependent claim 3 and reserves the right to assert additional claims as the case progresses (Compl. ¶¶16, 35).

III. The Accused Instrumentality

Product Identification

The "Alcatel-Lucent Rainbow Software" (the "Accused Instrumentality") (Compl. ¶17).

Functionality and Market Context

The complaint alleges the Accused Instrumentality is a software solution that "enables a method for sharing presence information" (Compl. ¶17). Its relevant functionality is described as including a "channel module" that stores group information like channel name and member lists, which the complaint equates to the claimed "group server" (Compl. ¶¶21-22). The software also allegedly gathers and stores "individual status information" (e.g., "available/away/do not disturb") in what the complaint considers a "presence server" (Compl. ¶¶20, 23). The complaint further alleges that the software combines this group and presence data to show the presence of channel members and sends this combined information to group members (Compl. ¶¶21, 24).

IV. Analysis of Infringement Allegations

The complaint references an exemplary claim chart in "Exhibit B" but does not attach it; the following analysis is based on the narrative allegations in the complaint body (Compl. ¶17). No probative visual evidence provided in complaint.

’479 Patent Infringement Allegations

Identified Points of Contention

• Architectural Questions: The complaint alleges that software modules within the Accused Instrumentality, such as a "channel module" and a server housing an "individual identity information database," correspond to the claimed "group server" and "presence server" (Compl. ¶¶20-22). A central point of contention may be whether these software components within a single product satisfy the claim limitations, which describe distinct entities. The defense may argue for a narrower interpretation requiring physically or logically separate servers as depicted in the patent's figures (e.g., ’479 Patent, Fig. 3).
• Functional Questions: The infringement theory rests on the allegation that the Accused Instrumentality performs a specific sequence of "acquiring" distinct types of information, "combining" them into "group presence information," and "sending" the result. A technical question will be whether discovery reveals that the accused software operates in this specific manner, or if its method for displaying presence status differs fundamentally from the claimed process.

V. Key Claim Terms for Construction

"group server" / "presence server"

Context and Importance: These terms are foundational to the patent's architecture. The infringement case hinges on whether components of the Accused Instrumentality can be properly characterized as a "group server" and a "presence server." Practitioners may focus on these terms because the complaint maps them to software modules within a single "Rainbow Software" product (Compl. ¶¶20-22), raising the question of whether the claims require distinct apparatuses or merely distinct functions.

Intrinsic Evidence for Interpretation:

• Evidence for a Broader (Functional) Interpretation: The claims themselves are directed to a "method" and refer to apparatuses like a "group server" functionally by what they do (e.g., providing "basic group information") (’479 Patent, col. 16:5-7). Claim 17, for example, claims a "group server" comprising a "subscription unit" and a "presence information transceiver unit," defining the server by its functional components.
• Evidence for a Narrower (Structural) Interpretation: The patent’s figures and detailed description consistently depict the "group server" and "presence server" as separate structural boxes connected by communication links (’479 Patent, Figs. 3, 4, 6-8). The specification describes a system where "the group server 301 sends the basic group information to the presence server 302" (’479 Patent, col. 7:37-38), language that suggests two distinct entities interacting.

"group presence information"

Context and Importance: This term is defined within Claim 1 itself as a combination of two other distinct types of information. The strength of the infringement allegation depends on showing that the data aggregated and sent by the accused software meets this specific composite definition.

Intrinsic Evidence for Interpretation:

• Evidence for a Broader Interpretation: The term is defined broadly in the claim as comprising "basic group information" and "presence information." The specification further notes that the information can be combined in various ways, such as in a "multipart/related format," suggesting flexibility (’479 Patent, col. 9:55-58).
• Evidence for a Narrower Interpretation: The claim requires that the constituent "basic group information" must itself comprise three specific sub-elements: "a group attribute, a group member list and a group member attribute" (’479 Patent, col. 16:6-8). An infringement read would have to demonstrate that the data from the accused "channel module" includes all three of these specific sub-types of information.

VI. Other Allegations

Willful Infringement

The complaint alleges that Defendant had knowledge of infringement "at least as of the service of the present Complaint" (Compl. ¶30). This allegation supports a claim for post-filing willfulness but does not plead any specific facts suggesting Defendant had pre-suit knowledge of the ’479 patent or its alleged infringement.

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

• A core issue will be one of architectural mapping: can the "channel module" and "individual identity information database" functions within the single, integrated "Alcatel-Lucent Rainbow Software" be construed to meet the "group server" and "presence server" limitations of the claims, which the patent specification often depicts as distinct interacting entities?
• A key evidentiary question will be one of functional specificity: does discovery evidence show that the accused software performs the precise sequence of acquiring separate "basic group information" and "presence information," combining them, and then sending the specific combined result, or does it utilize a different technical method to display user presence that falls outside the claim language?
• The viability of the willfulness claim will depend on whether pre-suit knowledge can be established during discovery, as the complaint currently lacks factual allegations to support it.
