3:26-cv-00526
VDPP LLC v. CoStar Tech Inc
I. Executive Summary and Procedural Information
Parties & Counsel:
- Plaintiff: VDPP, LLC (Oregon)
- Defendant: COSTAR TECHNOLOGIES, INC., d/b/a COSTAR VIDEO SYSTEMS, LLC (Delaware)
- Plaintiff’s Counsel: Ramey LLP
Case Identification: 3:26-cv-00526, N.D. Tex., 02/18/2026
Venue Allegations: Plaintiff alleges venue is proper in the Northern District of Texas because Defendant maintains a regular and established place of business in Coppell, Texas, and has committed alleged acts of infringement in the district.
Core Dispute: Plaintiff alleges that Defendant’s systems, products, and services related to image capture and streaming infringe a patent concerning electronically controlled spectacles for creating a 3D visual effect.
Technical Context: The patent-in-suit addresses methods for improving the performance of variable-tint eyewear used to generate a 3D illusion (the Pulfrich effect) from standard 2D video content by enabling faster transitions between light and dark lens states.
Key Procedural History: U.S. Patent No. 9,699,444 was the subject of an ex parte reexamination, which concluded with the issuance of a Reexamination Certificate on December 11, 2024, cancelling claims 26-27. The complaint, filed after the certificate issued, asserts claims 1-27, including the cancelled claims. The complaint also preemptively addresses patent marking requirements under 35 U.S.C. § 287(a), arguing that prior settlement licenses did not involve the production of a patented article and thus did not trigger a duty to mark.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,699,444 - Faster state transitioning for continuous adjustable 3deeps filter spectacles using multi-layered variable tint materials
- Patent Identification: U.S. Patent No. 9,699,444, issued July 4, 2017.
The Invention Explained
Problem Addressed: The patent addresses performance limitations in electronically controlled spectacles designed to create a 3D visual effect from 2D motion pictures via the Pulfrich illusion Compl. ¶7 The background section identifies two key technical problems: the "slow transition time" of variable tint materials when changing between different optical densities, and the limited "cycle life" (the number of clear-dark cycles before failure) of some of these materials '444 Patent, col. 2:28-40 '444 Patent, col. 2:61-64
The Patented Solution: The invention proposes using spectacles with lenses fabricated from "multiple layers" of electronically controlled variable tint materials '444 Patent, col. 2:52-57 According to the specification, this multi-layer structure allows for faster transitions between optical states, as the combined effect of several layers changing slightly can achieve a target density more quickly than a single layer making a large change '444 Patent, col. 2:52-60 The patent's abstract describes the core system as a spectacle with left and right "optoelectronic lenses" whose states are controlled independently by a control unit housed in the frame '444 Patent, abstract '444 Patent, Fig. 1
Technical Importance: This approach suggests a way to improve the responsiveness and durability of active eyewear synchronized with video content, potentially making the 3D effect more convincing and reliable, especially during rapid on-screen action or scene changes '444 Patent, col. 2:40-52
Key Claims at a Glance
The complaint asserts infringement of claims 1-27 Compl. ¶8 The independent claims not cancelled by the subsequent reexamination are Claims 1 and 15.
Independent Claim 1:
- An electrically controlled spectacle for viewing a video, comprising:
- a spectacle frame;
- optoelectronic lenses housed in the frame, comprising a left lens and a right lens, each having a plurality of states;
- wherein the state of the left lens is independent of the state of the right lens; and
- a control unit housed in the frame, adapted to control the state of each lens independently.
Independent Claim 15:
- A method for viewing a video, comprising:
- providing an electrically controlled spectacle for a user to wear, the spectacle comprising a frame, independently controllable left and right optoelectronic lenses, and a control unit; and
- showing the user a video having dissimilar bridge frames and similar image frames.
III. The Accused Instrumentality
Product Identification
The complaint does not identify any specific accused product, method, or service by name Compl. ¶¶8-10 It broadly accuses "systems, products, and services in the field of image image capture, streaming, modification and displaying" Compl. ¶8
Functionality and Market Context
The complaint does not provide any description of the relevant features, technical functionality, or market positioning of any accused instrumentality.
IV. Analysis of Infringement Allegations
The complaint alleges that Defendant's unspecified products and services infringe claims 1-27 of the '444 Patent Compl. ¶8 It states that "[s]upport for the allegations of infringement may be found in the preliminary exemplary table attached as Exhibit B" Compl. ¶9 However, this Exhibit B was not provided with the complaint document, and no further detail mapping accused functionalities to claim elements is present in the pleading.
No probative visual evidence provided in complaint.
- Identified Points of Contention:
- Pleading Sufficiency: A primary legal question is whether the complaint's failure to identify a single accused product or provide any factual allegations detailing how an accused product operates is sufficient to state a plausible claim for relief under the Twombly/Iqbal pleading standard.
- Technical Mismatch: A foundational technical question arises from the apparent disconnect between the claimed invention—a physical "spectacle" with "lenses"—and the accused field of "image capture, streaming, modification and displaying" Compl. ¶8 The case may turn on whether Plaintiff can identify an accused instrumentality that falls within the scope of a "spectacle."
V. Key Claim Terms for Construction
The complaint does not provide sufficient detail for a full analysis of claim construction disputes. However, based on the mismatch between the patent's subject matter and the broadly accused field, the following terms may become central to the dispute if and when an accused product is identified.
The Term: "spectacle"
Context and Importance: This term appears in independent claim 1 and defines the overall apparatus. The patent consistently depicts and describes a physical piece of eyewear '444 Patent, Fig. 1 '444 Patent, abstract '444 Patent, col. 5:46-56 Practitioners may focus on this term because its construction will determine whether the claims can read on non-eyewear products, such as software or server-side systems, which may be implicated by the complaint's vague reference to "image capture" and "streaming" systems Compl. ¶8
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The complaint does not provide a basis to analyze this.
- Evidence for a Narrower Interpretation: The patent specification describes the invention as "spectacles for viewing 2D movies as 3D movies" '444 Patent, col. 2:60-61 The abstract and all corresponding figures depict a physical frame with lenses worn by a user '444 Patent, abstract '444 Patent, Fig. 1 '444 Patent, Fig. 5
The Term: "optoelectronic lenses"
Context and Importance: This term from claim 1 defines the core functional component that modulates light. Its definition is critical to determining what technology infringes. If the accused instrumentality is software-based, a key dispute will be whether a digital image manipulation process can be construed as an "optoelectronic lens."
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The complaint does not provide a basis to analyze this.
- Evidence for a Narrower Interpretation: The specification explicitly identifies the types of physical materials contemplated, including "electrochromic devices, suspended particle devices, and polymer dispersed liquid crystal devices" '444 Patent, col. 2:1-4 These examples suggest the term refers to physical hardware components that control the transmission of light '444 Patent, col. 19:26-34
VI. Other Allegations
- Indirect Infringement: The complaint does not contain specific counts for indirect or contributory infringement, nor does it allege facts to support the requisite knowledge or intent for such claims.
- Willful Infringement: The complaint does not allege that Defendant had pre-suit knowledge of the '444 Patent. Instead, it includes a conditional prayer for enhanced damages and a finding of willfulness "provided discovery reveals" pre-suit knowledge and subsequent infringement Compl. p. 6, ¶e
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of pleading sufficiency: does the complaint’s failure to identify any accused product or provide factual allegations of its operation meet the plausibility standard required to survive a motion to dismiss for failure to state a claim?
- A key threshold question will be one of technical applicability: can an invention claimed as a physical "spectacle" with "optoelectronic lenses" be plausibly asserted against "systems, products, and services" in the field of digital image streaming and modification, or is there a fundamental mismatch in technology?
- A significant procedural question will be the effect of the reexamination: how will the court address the plaintiff's assertion of claims 26 and 27, which were cancelled by the USPTO in a reexamination that concluded more than a year before the complaint was filed?
