II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,409,599 - Interactive Virtual Reality Performance Theater Entertainment System
The Invention Explained
- Problem Addressed: The patent identifies a gap in prior art virtual reality (VR) systems, which focused on a user’s interaction with computer-generated objects rather than with live human performers. It also notes that traditional entertainment with live performers lacked the immersive qualities of VR and the ability for robust, multi-way communication among the audience and performers ('599 Patent, col. 1:57-2:54).
- The Patented Solution: The invention proposes a "three-way immersive interactive communication" system that connects participants, live (or pre-recorded) performers, and a shared VR environment ('599 Patent, col. 3:10-17). The system achieves this by capturing a video representation of the performer and superimposing it within the graphical VR world that participants view, enabling them to interact with both the environment and the live performer using input devices and audio communication ('599 Patent, Abstract; col. 4:5-12). The system architecture, illustrated in Figure 1, shows the flow of voice, video, and graphics data between actors, participants, and the VR environment.
- Technical Importance: The technology aimed to create a new category of shared experience by merging the real-time spontaneity of live performance with the interactive and immersive nature of virtual reality ('599 Patent, col. 3:5-9).
Key Claims at a Glance
- The complaint asserts only independent method claim 9 (Compl. ¶43).
- The essential steps of claim 9 include:
- Providing an "immersive virtual reality environment."
- Providing input and output devices for at least one "performer" and at least one "participant."
- Having a "live performer" interact with a "participant" by including a video image of the performer and audio communication within the VR environment.
- Having the participant interact with the live performer and the environment, resulting in an experience that is "in part controlled by" the participant via their input device.
III. The Accused Instrumentality
Product Identification
The complaint identifies the "Safran remote collaboration virtual reality" system and method as the accused instrumentality (Compl. ¶19, ¶40).
Functionality and Market Context
The complaint alleges that the accused instrumentality is a method for providing interactive communications between participants and performers within an immersive virtual reality environment (Compl. ¶41). It provides a link to a publicly available video as evidence of the accused method's operation. A video on YouTube, titled "Safran remote collaboration virtual reality," is cited as demonstrating the accused method (Compl. ¶40). The complaint does not provide detail regarding the product's commercial importance or market positioning.

| (g) having at least one participant interact with the live performer and the immersive virtual reality environment, resulting in an experience which is in part controlled by the participant and the participant input device. | The accused method allegedly has the participant interact with the live performer and the environment, creating an experience controlled in part by the participant's input device. | ¶41 | col. 16:6-12 |
Identified Points of Contention
- Scope Questions: The patent is titled and primarily describes an "Entertainment System." A potential issue is whether its claims, using terms like "performer" and "participant," can be construed to cover a professional "remote collaboration" tool, or if the claim scope is limited by the entertainment-focused context of the specification.
- Technical Questions: The complaint alleges the provision of an "immersive virtual reality environment" but does not provide facts demonstrating how the accused system meets the patent's specific quantitative definition for "immersive" (i.e., a display with a ">25 degree diagonal field of view" viewed from "no more than 10 feet") ('599 Patent, col. 4:61-64). The evidence needed to prove this claim element may become a central technical question.
V. Key Claim Terms for Construction
The Term: "immersive virtual reality environment"
Context and Importance
This term appears in the preamble and first step of the asserted claim and is a prerequisite for infringement. Its construction will be critical, as a narrow definition could place the accused professional collaboration tool outside the claim's scope.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: The patent offers a general, qualitative description, defining it as an environment where "a participant is 'immersed' ... so as to provide to the user a sensation of being physically located within the graphical environment" ('599 Patent, col. 1:39-43).
- Evidence for a Narrower Interpretation: The specification provides a specific, quantitative definition: "an 'immersive' display as one which has greater than a 25 degree diagonal field of view with a distance of no more than 10 feet from the viewer" ('599 Patent, col. 6:40-43). Parties may dispute whether this specific embodiment limits the general term.
The Term: "live performer"
Context and Importance
The infringement reading requires mapping users of the Safran system to the roles of "live performer" and "participant." Practitioners may focus on this term because the patent’s context of "entertainment" and "theater" may not align with the context of the accused "remote collaboration" tool.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: The specification suggests the term can encompass a "live host" who "interacts with participants" in various non-theatrical settings, such as registering them for the experience ('599 Patent, col. 7:7-12).
- Evidence for a Narrower Interpretation: The patent’s title, abstract, and background are heavily focused on "performance theater," "stand-up comedy," and "dramatic presentations," which could support an argument that a "performer" is limited to an entertainer in a more traditional sense ('599 Patent, Title; col. 5:21-24).
VI. Other Allegations
Indirect Infringement
The complaint alleges direct infringement under 35 U.S.C. § 271(a) (Compl. ¶40). It does not contain specific factual allegations required to plead induced or contributory infringement, such as knowledge of the patent and specific intent to encourage infringement.
Willful Infringement
The complaint does not contain an explicit allegation of willful infringement or a request for enhanced damages under 35 U.S.C. § 284. It does request a declaration that the case is "exceptional" for the purpose of recovering attorneys' fees under 35 U.S.C. § 285, but it does not allege pre-suit knowledge of the patent or other facts typically asserted to support a finding of willfulness (Compl. ¶C, p. 10).
VII. Analyst’s Conclusion: Key Questions for the Case
The resolution of this dispute may turn on the following central questions:
- A core issue will be one of definitional scope: can the term "immersive virtual reality environment", which the patent specification defines with specific quantitative metrics (e.g., a >25 degree field of view from <10 feet), be met by the accused collaboration tool? The complaint does not allege facts to satisfy this specific definition, making it a likely point of failure if the definition is adopted during claim construction.
- A second key issue will be one of contextual limitation: will the patent’s pervasive framing around "entertainment," "theater," and "performance" limit the scope of terms like "live performer" to an entertainment context? This raises the question of whether a professional presenter in a corporate collaboration setting can be considered a "performer" as that term is used in the patent.
