Case Timeline

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

U.S. Patent No. 11,290,428 - "Telecommunication method and system for simplifying communication such as conference calls," issued March 29, 2022

The Invention Explained

• Problem Addressed: The patent's background section identifies several problems with conventional teleconferencing systems, including the "colossal waste of valuable professional time" spent coordinating schedules, the difficulty of finding call-in details within numerous emails, and the potential for meetings to be derailed by technically unsophisticated attendees struggling with materials ('428 Patent, col. 1:29-57).
• The Patented Solution: The invention proposes a system where a host selects participants using their unique "electronic identifiers" (e.g., a phone number, Skype address, or website address) ('428 Patent, col. 7:8-11). The system then automatically establishes a "conference bridge" and, at a scheduled time, simultaneously initiates a call to all users, rather than requiring them to dial in ('428 Patent, col. 7:32-38). This process is designed to be largely passive for the attendees, enhance privacy by not exposing core contact details like phone numbers, and streamline the joining process ('428 Patent, col. 8:46-51).
• Technical Importance: The described approach seeks to shift the burden of connection from the end-user to a centralized system, thereby reducing friction and the potential for user error in joining multi-party communications ('428 Patent, col. 4:50-58).

Key Claims at a Glance

• The complaint asserts infringement of one or more claims, with specific claims identified in an unprovided exhibit (Compl. ¶11). Claim 1 is the sole independent claim of the patent.
• Independent Claim 1 elements:
  • A method of simplifying electronic communications between selected users, each having at least one electronic identifier.
  • Selecting a plurality of users for simultaneous contact at a predetermined time from a provided or determined identifier of each user.
  • Collating a respective identifier of all selected users.
  • Forming a conferencing bridge where the identifier of each selected user is on said bridge at the predetermined time in advance of contacting selected users without any action by said selected users.
  • Simultaneously contacting bridged identifiers of all selected users at said predetermined time absent any action by any selected user.
  • Enabling communication between all selected users.
  • Precluding contacted nonresponsive selected users from communication unless subsequently authorized.
• The complaint does not explicitly reserve the right to assert dependent claims, but refers generally to "one or more claims" (Compl. ¶11).

III. The Accused Instrumentality

Product Identification

The complaint does not name specific accused products in its main body, referring to them generally as the "Exemplary Defendant Products" (Compl. ¶11). It states these products are identified in charts incorporated as Exhibit 2, which was not filed with the complaint (Compl. ¶16).

Functionality and Market Context

The complaint alleges that the "Exemplary Defendant Products" practice the technology claimed by the '428 Patent (Compl. ¶16). Based on the nature of the patent and the Defendant's business, these are teleconferencing and remote communication software products. The complaint alleges that Defendant makes, uses, sells, and markets these products in the United States (Compl. ¶14). The complaint does not provide further detail on the specific technical operation or market positioning of the accused products.

IV. Analysis of Infringement Allegations

The complaint alleges that the "Exemplary Defendant Products" infringe the '428 Patent by practicing the claimed technology (Compl. ¶16). However, it relies on claim charts in "Exhibit 2" to detail its infringement theory, and this exhibit was not provided with the publicly filed complaint (Compl. ¶17). Therefore, a detailed element-by-element analysis based on the complaint's allegations is not possible.

The core narrative theory is that Defendant's products, when used as intended, perform the steps of the asserted claims, including selecting users, establishing a communication session, and connecting the users to that session (Compl. ¶11, ¶16).

No probative visual evidence provided in complaint.

• Identified Points of Contention:
  • Scope Questions: A central question will likely be the interpretation of the limitation "absent any action by any selected user" ('428 Patent, col. 14:3-4). The infringement analysis may turn on whether a user clicking a "Join" link or button in a software application constitutes an "action" that would place the accused functionality outside the scope of the claim.
  • Technical Questions: The complaint does not provide evidence demonstrating that the accused products perform the specific sequence of "forming a conferencing bridge where the identifier of each selected user is on said bridge... in advance of contacting selected users" ('428 Patent, col. 13:42-45). A key factual dispute may be whether the accused systems technically pre-load user identifiers onto a bridge before initiating contact, or if these events occur concurrently or in a different order.

V. Key Claim Terms for Construction

• The Term: "absent any action by any selected user"

  • Context and Importance: This phrase appears twice in independent claim 1 and is fundamental to the patent's purported novelty of creating a passive joining experience for users. Practitioners may focus on this term because most modern teleconferencing systems require an affirmative user action (e.g., clicking a link, entering a password, pressing a button in an app) to join a meeting. The viability of the infringement claim could depend entirely on whether such a click is considered an "action" under the claim.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: A party might argue "action" implies more significant steps, such as dialing a number and entering a code, which the patent sought to eliminate ('428 Patent, col. 7:38-44). The specification's focus on eliminating the need for users to "call the system with the additional requirement to input a code" could support an interpretation that simple, single-click interactions are not the "action" the claim precludes.
    • Evidence for a Narrower Interpretation: A party could argue that the plain and ordinary meaning of "any action" is absolute and includes any volitional step by the user, including clicking a button. The specification describes the system itself initiating the call to the users, which supports a view that the invention contemplates a process with zero user input at the moment of connection ('428 Patent, col. 7:35-38).

• The Term: "forming a conferencing bridge where the identifier of each selected user is on said bridge at the predetermined time in advance of contacting selected users"

  • Context and Importance: This limitation dictates a specific temporal sequence: the bridge must be formed and populated with identifiers before the system reaches out to the users. This sequence could be a critical point of distinction between the patented method and the operation of the accused products.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The term "in advance" might be interpreted flexibly to mean logically prior in the system's workflow, even if the time gap is milliseconds and functionally simultaneous to the user.
    • Evidence for a Narrower Interpretation: The explicit language "in advance of contacting" suggests a distinct, completed preparatory step. The patent's flow chart in Figure 2, showing "PREPARE MEETING AND THEN DIAL OUT" as two sequential high-level steps (84, 86), may be used to argue for a strict, temporally separated interpretation.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that since the filing of the complaint, Defendant has acted "knowingly, and intentionally" by selling its products to customers for infringing uses (Compl. ¶15). The basis for this allegation includes the distribution of "product literature and website materials" that allegedly instruct users on how to use the products in an infringing manner (Compl. ¶14).
• Willful Infringement: The complaint does not contain a separate count for willful infringement. However, it alleges that the service of the complaint provides Defendant with "Actual Knowledge of Infringement" (Compl. ¶13) and the prayer for relief requests enhanced damages pursuant to 35 U.S.C. § 284 (Compl. p. 5, ¶D), which is the statutory basis for willfulness. This suggests Plaintiff is pursuing a theory of post-filing willfulness.

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

1. A core issue will be one of definitional scope: can the phrase "absent any action by any selected user" be construed to read on a teleconferencing system where users must affirmatively click a software button or link to join a meeting? The answer will likely determine the viability of the infringement claim.
2. A central evidentiary question will be one of technical operation: does the accused TeamViewer software perform the specific, two-part sequence required by Claim 1 of first "forming a conferencing bridge... in advance" and then "simultaneously contacting" users, or is there a fundamental mismatch in its technical architecture and workflow? The complaint's lack of detail elevates this from a minor dispute to a primary hurdle for the Plaintiff.
