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

U.S. Patent No. 10,021,380 - "Faster State Transitioning for Continuous Adjustable 3Deeps Filter Spectacles Using Multi-Layered Variable Tint Materials" (Issued July 10, 2018)

The Invention Explained

• Problem Addressed: The patent addresses the technical challenge of creating 3D visual effects from 2D motion pictures using variable-tint spectacles. A key problem identified is the "slow transition time" of the tinting materials, which prevents the spectacles from adjusting their optical density quickly enough to synchronize with rapid changes in on-screen motion, thereby diminishing the 3D effect (’380 Patent, col. 3:24-42). A related problem is the limited "cycle life" of some tinting materials, which can be exhausted by frequent changes in electrical potential (’380 Patent, col. 3:57-64).
• The Patented Solution: The invention proposes using "multiple layers" of electronically controlled variable tint material to construct the spectacle lenses (’380 Patent, col. 4:1-5). This multi-layer structure, illustrated in Figure 6b, is designed to achieve faster transitions between different levels of tint (optical density) because the required electrical potential can be applied for a shorter duration to achieve the target state (’380 Patent, col. 3:48-56).
• Technical Importance: This approach sought to improve the viability of creating dynamic 3D effects from conventional 2D content by overcoming the inherent physical latency of the variable-tint materials used in active eyewear (’380 Patent, col. 3:13-23).

Key Claims at a Glance

• The complaint does not identify specific claims of the ’380 Patent but alleges infringement of "one or more claims" (Compl. ¶9). Independent method claim 1 is representative:
  • Acquiring a source video with a sequence of image frames.
  • Identifying first and second image frames at different chronological positions.
  • "Expanding" the first image frame to generate a "modified first image frame."
  • "Expanding" the second image frame to generate a "modified second image frame."
  • "Combining" the two modified image frames to generate a "modified combined image frame."
  • Displaying the modified combined image frame.
• The complaint reserves the right to assert additional claims (Compl. ¶11).

U.S. Patent No. 9,426,452 - "Faster State Transitioning for Continuous Adjustable 3Deeps Filter Spectacles Using Multi-Layered Variable Tint Materials" (Issued August 23, 2016)

The Invention Explained

• Problem Addressed: As a member of the same patent family, the ’452 Patent addresses the same core problem as the ’380 Patent: the "slow transition time" of variable tint lenses, which hinders their ability to optimally synchronize with on-screen motion to produce a convincing 3D effect via the Pulfrich illusion (’452 Patent, col. 2:25-33).
• The Patented Solution: The invention is an apparatus, specifically an "electrically controlled spectacle" that includes a frame, a control unit, and optoelectronic lenses for the left and right eyes. The key feature is that the state of each lens (e.g., its tint level) is controlled "independently" by the control unit, and the lenses are constructed from multiple layers of variable tint material to enable faster state transitions (’452 Patent, Abstract; col. 2:48-56).
• Technical Importance: The invention describes a hardware system designed to make the real-time generation of 3D effects from 2D video more robust and effective by improving the responsiveness of the viewing eyewear.

Key Claims at a Glance

• The complaint asserts claims 1-4 of the ’452 patent (Compl. ¶15). Claim 1 is the sole independent claim.
  • A system comprising an apparatus (with storage and a processor) and an "electrically controlled spectacle."
  • The spectacle includes a frame, a control unit, and left and right optoelectronic lenses.
  • The state of the left lens is "independent of the state of the right lens."
  • The control unit is "adapted to control the state of each of the lenses independently."
  • Each lens has a "dark state and a light state."
  • The control unit places both lenses in a dark state when viewing the video.
• The complaint explicitly asserts dependent claims 2-4 (Compl. ¶15).

III. The Accused Instrumentality

Product Identification

The complaint does not identify any specific accused products, methods, or services by name (Compl. ¶9, ¶15). It refers generally to Defendant’s "systems, products, and services in the field of motion pictures" (Compl. ¶9).

Functionality and Market Context

The complaint does not provide sufficient detail for analysis of the functionality of any accused instrumentality. It makes only conclusory allegations that Defendant "maintains, operates, and administers" systems that perform the infringing methods or processes, without describing how those systems operate (Compl. ¶9, ¶15).

No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint references preliminary claim charts in Exhibits B and D but does not attach them, instead stating the allegations are preliminary (Compl. ¶10, ¶16). It provides a narrative theory that is conclusory, alleging that Defendant’s unspecified "systems, products, and services" infringe the patents-in-suit (Compl. ¶9, ¶15). Without identified products or claim charts, a detailed infringement analysis based on the complaint is not possible.

Identified Points of Contention

• Scope Questions: The central infringement question for the ’452 Patent is what, if any, Razer product constitutes an "electrically controlled spectacle" with independently controlled left and right lenses. For the ’380 Patent, a key question is what Razer product performs the claimed video modification method. The complaint’s failure to identify any accused product raises a fundamental question of how Plaintiff intends to map the claims, which are directed to viewing spectacles and video processing for 3D effects, onto Defendant's product lines.
• Technical Questions: A primary evidentiary challenge for Plaintiff will be to demonstrate that any accused Razer product actually performs the specific technical functions required by the claims. For instance, what evidence will be presented to show that a Razer product performs the "expanding" and "combining" of image frames as recited in claim 1 of the ’380 patent, or embodies a system with independently controllable lenses as required by claim 1 of the ’452 patent.

V. Key Claim Terms for Construction

The Term: "electrically controlled spectacle" (’452 Patent, Claim 1)

• Context and Importance: This term defines the core apparatus of the ’452 Patent. As Defendant Razer is primarily known for gaming peripherals and computers rather than eyewear, the construction of this term will be fundamental to determining whether any of its products could fall within the claim's scope.
• Intrinsic Evidence for a Broader Interpretation: The specification discusses various 3D viewing technologies, including shutter glasses and polarized systems, which could support an argument that "spectacle" is not limited to a conventional eyeglass form factor but could encompass other head-mounted or viewing devices (’452 Patent, col. 17:11-21, col. 32: Table 1).
• Intrinsic Evidence for a Narrower Interpretation: The patent's figures consistently depict a device with the form factor of traditional eyeglasses (’452 Patent, Fig. 1, 5, 11). The abstract and claims refer to a "spectacle frame" and "lenses housed in the frame," language that may support a narrower construction limited to devices resembling eyewear (’452 Patent, Abstract; Claim 1).

The Term: "expanding the first image frame to generate a modified first image frame" (’380 Patent, Claim 1)

• Context and Importance: This term describes a specific step in the claimed video modification method. Its construction will be critical for determining whether any video processing performed by a Razer product constitutes infringement, as Defendant will likely argue its technology does not perform this exact operation.
• Intrinsic Evidence for a Broader Interpretation: The specification describes numerous ways to alter frames, including creating the "appearance of the window moving and/or enlarging or shrinking in size" (’380 Patent, col. 10:21-23). Plaintiff may argue "expanding" should be interpreted broadly to cover various modification techniques that result in an altered or enlarged image portion.
• Intrinsic Evidence for a Narrower Interpretation: The claim uses the specific word "expanding." A defendant could argue this term should be given its plain meaning of a geometric scaling operation, as distinct from other modifications described elsewhere in the patent, such as blending, stitching, or shifting image elements (’380 Patent, col. 47:1-17).

VI. Other Allegations

Indirect Infringement

The complaint alleges direct and indirect infringement, including inducement, of the ’452 patent (Compl. ¶18). However, it does not plead specific facts to support the knowledge and intent elements of inducement, such as referencing user manuals or advertising that instruct users on an infringing use. For the ’380 patent, Plaintiff "reserves the right to add indirect infringement claims" pending discovery (Compl. ¶11).

Willful Infringement

The complaint does not allege pre-suit knowledge but includes a contingent request in its prayer for relief for a finding of willfulness and enhanced damages should discovery reveal that Defendant knew of the patents prior to the lawsuit (Compl. ¶e, p.5).

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

The Specificity Question

A threshold issue is whether the complaint’s failure to identify a single accused product or provide any factual detail on the mechanism of infringement meets the plausibility standard under Federal Rule of Civil Procedure 8, raising the question of whether it provides Defendant with fair notice of the claims against it.

The Definitional Mismatch Question

A central substantive issue will be one of scope and potential mismatch: can the term "electrically controlled spectacle," which is described and depicted in the context of variable-tint eyewear for viewing external screens, be plausibly construed to cover products from a gaming hardware and software company like Razer?

The Technical Equivalence Question

A key evidentiary challenge will focus on technical operation: assuming an accused product is identified, does its functionality align with the specific video processing steps of the ’380 patent, such as "expanding" and "combining" image frames, or is there a fundamental difference in the technical method employed?
