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"

• Issued: March 19, 2013

The Invention Explained

• Problem Addressed: The patent describes prior art video and chat systems as being too constrictive and inadequate for the complex interactions required by modern "social networks" and "communities" (e.g., "MySpace" or "StudiVZ") (’099 Patent, col. 2:3-11, 50-53). These earlier systems lacked the flexibility for users to define their online identity and control their interactions in a nuanced way ('099 Patent, col. 2:44-53).
• The Patented Solution: The invention is a process where a user generates a "virtual subscriber profile" on a server or peer-to-peer network ('099 Patent, Abstract). This profile is more than a simple login; it allows the user to define a "subscriber selection mode" (e.g., random connection, searching, or calling from a friends list), the communication type, and the number of communication links ('099 Patent, col. 2:22-31). The system uses these profiles to group users into "sub-pools," enabling complex, user-defined interactions like one-to-one chats, one-to-many broadcasts ("places"), and group conferences ('099 Patent, col. 8:3-15, Fig. 2).
• Technical Importance: The described approach aims to replicate the complexity of real-world social interactions in an online environment, moving beyond simple one-to-one chat to support dynamic, community-based communication structures ('099 Patent, col. 2:54-60).

Key Claims at a Glance

• The complaint does not identify specific claims, but reserves the right to assert one or more claims of the '099 patent (Compl. ¶10). Independent claim 1 is a representative method claim.
• Independent Claim 1 (Method):
  • Executing a multimedia communication between terminals on a network.
  • At least one subscriber generates a personalized user account as a "virtual subscriber profile" on a server or peer-to-peer network.
  • Setting up the virtual subscriber profile establishes the multimedia communication at each terminal.
  • The profile is used to freely define a "mode of a subscriber selection," a communication type, a number of links, or a type of data transmission.
  • The subscriber selection mode includes a "random process" for linking to a random subscriber profile.
  • The subscriber selection mode also includes a "call procedure" for linking to a subscriber profile from a "selection list."
  • These subscribers in the call procedure form at least one "open and a closed subscriber sub-pool," where all subscribers are classified by entries in their profiles and contacts, forming subsets of a larger subscriber pool.

III. The Accused Instrumentality

Product Identification

• The complaint does not identify any specific accused product, method, or service by name (Compl. ¶¶ 2, 10). It refers generally to "products and services" sold by Defendant that allegedly "perform infringing methods or processes" for "conducting electronic communication" (Compl. ¶¶ 2, 8).

Functionality and Market Context

• The complaint does not provide any description of the functionality of the accused instrumentalities. It alleges that Defendant introduces these unspecified products and services into the stream of commerce, knowing they would be sold in the district (Compl. ¶2). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint references a claim chart in "Exhibit B" but does not attach it (Compl. ¶9). Therefore, the specific theory of infringement is not detailed. The complaint makes general allegations that Defendant "has caused and will continue to cause Plaintiff damage by direct and indirect infringement of (including inducing infringement of) the claims of the '099 patent" (Compl. ¶11).

• Identified Points of Contention:
  • Technical Questions: A primary question will be whether Plaintiff can produce evidence that Defendant’s unspecified "products and services" actually perform the specific steps of the asserted claims. For example, what evidence demonstrates that Defendant's systems implement a "random process" for connecting users or a "call procedure" that organizes users into "sub-pools" as claimed ('099 Patent, col. 22:42-59)?
  • Scope Questions: Given the patent's focus on "social networks" and rich multimedia chat ('099 Patent, col. 2:48-53), a central dispute may arise over whether the claims can be read to cover the features of what is presumably a conventional retail e-commerce platform.

V. Key Claim Terms for Construction

• The Term: "virtual subscriber profile"

• Context and Importance: This term appears in all independent claims. The infringement analysis will depend heavily on whether a standard user account on an e-commerce website constitutes a "virtual subscriber profile." Practitioners may focus on this term because the patent's specification appears to describe a more complex entity than a typical retail account.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent states that the profile is a form of a "personalized user account" ('099 Patent, col. 2:23-24) and can include basic information like "login data, contacts, the profile, switching and management-relevant data" ('099 Patent, col. 2:45-48).
  • Evidence for a Narrower Interpretation: The specification repeatedly describes the profile as a tool for "self-portrayal" within a social network, allowing a user to define "preferences and basic parameters" for communication, including how and with whom they wish to interact ('099 Patent, col. 2:40-44, 54-60). It is also described as containing "like tags," "dislike tags," and "WhoAmI tags" to facilitate matching with other users ('099 Patent, col. 11:24-27).

• The Term: "subscriber sub-pool"

• Context and Importance: This term is critical to the structure of claim 1 and defines how users are grouped. Infringement will turn on whether any user grouping on the accused platform (e.g., marketing segments) meets the definition of a "sub-pool."

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: A sub-pool is a "defined subset of the main pool" where subscribers are "logically grouped according to specific criteria" ('099 Patent, col. 8:9-11; col. 20:47-48).
  • Evidence for a Narrower Interpretation: The specification provides specific examples of sub-pools, such as a "friends" list, a "blacklist," users in a multi-connect "place" (i.e., a virtual stage), and an "audience" for a stream ('099 Patent, col. 8:11-24, Fig. 2). These examples are rooted in active, user-driven social communication rather than passive commercial categorization.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement by asserting that Defendant "actively encouraged or instructed others (e.g., its customers...)" on how to use its products and services in an infringing manner (Compl. ¶10).
• Willful Infringement: Willfulness is alleged based on Defendant’s knowledge of the '099 patent "from at least the filing date of the lawsuit" (Compl. ¶10). The complaint also includes a conditional request for a willfulness finding should discovery reveal pre-suit knowledge (Compl. p. 4, ¶e).

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

• A core issue will be one of definitional scope: can terms like "virtual subscriber profile" and "subscriber sub-pool", which the patent repeatedly describes in the context of rich social networking and multimedia chat platforms, be construed to cover the features of a conventional e-commerce system?
• A key threshold question will be one of factual particularity: can the plaintiff amend its complaint or otherwise provide sufficient factual evidence to identify the specific accused products and map their functionalities to the detailed limitations of the asserted claims, overcoming the high level of generality in the initial pleading?
