Case Timeline

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

U.S. Patent No. 8,402,099 - "Method For Carrying Out A Multimedia Communication Based On A Network Protocol Particularly TCP/IP And/Or UDP"

• Patent Identification: U.S. Patent No. 8,402,099, "Method For Carrying Out A Multimedia Communication Based On A Network Protocol Particularly TCP/IP And/Or UDP," issued March 19, 2013.

The Invention Explained

• Problem Addressed: The patent asserts that prior art video and chat systems were too "constrictive" and failed to adequately support the complex, differentiated communication requirements of emerging "social networks" and "communities" ('099 Patent, col. 1:42-53).
• The Patented Solution: The invention proposes a process where a user first generates a "virtual subscriber profile" on a server or peer-to-peer network. This profile is not merely an identity, but a mechanism to pre-define communication parameters, such as the mode for selecting other users (e.g., random, search-based, friends list), the type of communication, and the number of links. This profile setup establishes and governs how subsequent multimedia communications will occur ('099 Patent, col. 2:21-31). The system architecture is described as a hierarchical structure of layers, including a database layer, a link layer, a subscriber layer, and a front-end layer, to manage these interactions ('099 Patent, Fig. 1; col. 6:62-68).
• Technical Importance: This approach sought to provide a more flexible and robust framework for online interactions, moving beyond simple point-to-point connections to enable more nuanced, community-based communications ('099 Patent, col. 2:6-11).

Key Claims at a Glance

• The complaint asserts claims 1-20 of the '099 patent (Compl. ¶8). Independent claim 1 is central.
• Independent Claim 1 Elements:
  • A method for executing a multimedia communication between a totality of terminals in a network.
  • At least one subscriber generates a personalized user account in the form of a virtual subscriber profile on a server or in a peer-to-peer network.
  • By setting up the virtual subscriber profile, the multimedia communication is established at each of the terminals.
  • The subscriber profile is used to freely define a mode of subscriber selection, a communication type, a number of communication links, or a type of data transmission.
  • The subscriber selection mode includes a random process for connecting to a random subscriber profile.
  • The subscriber selection mode also includes an activatable call procedure for connecting to a subscriber profile stored in a selection list.
  • The subscribers in the selection list form a plurality of "at least one of an open and a closed subscriber sub-pool."
• The complaint does not explicitly reserve the right to assert dependent claims, but the general assertion of claims 1-20 implies they are at issue (Compl. ¶8).

III. The Accused Instrumentality

Product Identification

• The complaint broadly identifies the accused instrumentalities as "systems, products, and services that facilitate multimedia communication, in particular video, audio, and/or text chat between terminals" operated by Defendant Lamps Plus (Compl. ¶8).

Functionality and Market Context

• The complaint does not describe the specific functionality of the accused systems beyond the general allegation that they facilitate multimedia chat (Compl. ¶8). It does not identify specific products by name (e.g., a website chat feature) or provide details on their operation or market context.

IV. Analysis of Infringement Allegations

The complaint states that support for its infringement allegations is found in an attached Exhibit B (Compl. ¶9). However, no exhibit is attached to the publicly filed document. The complaint itself provides only a conclusory allegation that Defendant's chat systems infringe claims 1-20 of the '099 patent (Compl. ¶8). Without the claim chart exhibit or more detailed factual allegations, a direct comparison of claim elements to accused functionality is not possible based on the provided document.

No probative visual evidence provided in complaint.

• Identified Points of Contention: Based on the high-level allegations and the patent's specific requirements, the dispute may focus on several key questions:
  • Technical Questions: What evidence demonstrates that the accused "systems" perform the specific steps of claim 1? For instance, does the accused chat functionality generate a "virtual subscriber profile" that actively defines future communication modes, or is it a more conventional, state-less chat initiation?
  • Scope Questions: Does a standard e-commerce customer support chat feature, if that is the accused instrumentality, meet the claimed limitation of a "subscriber selection mode" that includes both a "random process" and a "call procedure" for a "selection list"?
  • Structural Questions: Can the plaintiff show that users of the accused system form "subscriber sub-pools" as that term is described in the patent, which appears to contemplate a more complex social networking structure than a typical customer-to-agent chat system?

V. Key Claim Terms for Construction

• The Term: "virtual subscriber profile"

• Context and Importance: This term appears in the preamble of claim 1 and is foundational to the invention. The infringement analysis will depend on whether this term is construed broadly to mean any user account, or narrowly to require an account that includes the specific, pre-communication setup functions described in the patent. Practitioners may focus on this term because its construction could be dispositive; a standard chat system may not have a "profile" that "freely define[s]" the various communication parameters as required.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The complaint does not point to specific evidence for a broad interpretation. A party might argue that any account holding user data and preferences qualifies.
  • Evidence for a Narrower Interpretation: The specification states that through the profile, "a mode of a subscriber selection preceding the communication, a communication type and/or a number of communication links...are freely defined" ('099 Patent, col. 2:27-31). It is also described as a platform for "self-portrayal" and inputting "connection preferences" ('099 Patent, col. 11:31-36), suggesting more than a simple login.

• The Term: "subscriber sub-pool"

• Context and Importance: Claim 1 requires that subscribers on a "selection list" form "a plurality of at least one of an open and a closed subscriber sub-pool." This structural limitation appears to require a specific method of user grouping. The viability of the infringement claim may depend on whether any grouping of users in the accused system (e.g., all available customer service agents) can be considered a "sub-pool."

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent states that "subscribers are logically grouped according to specific criteria" ('099 Patent, col. 8:9-10), which a party could argue applies to any logical grouping.
  • Evidence for a Narrower Interpretation: The specification provides specific examples of sub-pools, such as a "single-connect" group (11a), a "multi-connect" group with an "actor" (11b), nested groups (11c, 11d), and a "blacklist" of isolated users (11e) ('099 Patent, Fig. 2; col. 8:9-24). This suggests "sub-pool" is a term of art within the patent that requires these specific, defined structures.

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement. Inducement is based on allegations that Defendant "actively encouraged or instructed" its customers on how to use its services in an infringing manner (Compl. ¶10). Contributory infringement is based on the same allegations, coupled with the assertion that there are "no substantial noninfringing uses" for the services (Compl. ¶11).
• Willful Infringement: The complaint alleges that Defendant knew of the '099 patent "from at least the filing date of the lawsuit" (Compl. ¶10, ¶11). The prayer for relief requests a finding of willfulness and treble damages if discovery reveals pre-suit knowledge (Compl. ¶ VI.e).

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

• A central issue will be one of applicability: Can the plaintiff plausibly map the patent’s intricate social-networking architecture, which centers on a user-defined "virtual subscriber profile" and structured "sub-pools," onto what is presumably a more conventional e-commerce customer service chat system?
• A key question of claim scope will be whether the term "subscriber selection mode", which claim 1 requires to include both a "random process" and a "call procedure," can be read to cover the process by which a customer connects to a service agent.
• The case will likely present a significant evidentiary challenge for the plaintiff, who must move beyond the complaint's conclusory allegations to present concrete evidence showing that the accused systems perform each specific function and embody each structural limitation of the asserted claims.
