4:20-cv-11829
Lexidine LLC v. Brandmotion LLC
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Lexidine, LLC (Oklahoma)
- Defendant: Brandmotion, LLC (Michigan)
- Plaintiff’s Counsel: Grewal Law PLLC; Heninger Garrison Davis, LLC
- Case Identification: 2:20-cv-11829, E.D. Mich., 07/06/2020
- Venue Allegations: Venue is alleged to be proper in the Eastern District of Michigan because Defendant is organized in the district, maintains a regular and established place of business there, and has allegedly committed acts of infringement in the district.
- Core Dispute: Plaintiff alleges that Defendant’s aftermarket third brake light camera systems infringe a patent related to vehicle cameras integrated into vehicle light housings.
- Technical Context: The technology involves concealing a camera within a standard vehicle lighting assembly, such as a marker or brake light, to provide a less obtrusive and more integrated aftermarket safety solution.
- Key Procedural History: The complaint notes the patent-in-suit was subject to several assignments between the inventor and the plaintiff entity. More significantly, after the complaint was filed, the USPTO issued an Ex Parte Reexamination Certificate for the patent-in-suit, which canceled several claims, confirmed others, and amended the sole independent claim (Claim 1) asserted in the complaint. This amendment, which added limitations to the claim, will be central to the dispute.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,609,961 - "VEHICLE CAMERA"
- Patent Identification: U.S. Patent No. 7,609,961, "VEHICLE CAMERA", issued October 27, 2009.
The Invention Explained
- Problem Addressed: The patent’s background section describes prior art vehicle cameras as being "obtrusive in appearance," easily identifiable as cameras (making them "more probable" targets for theft), and often requiring the drilling of holes in the vehicle body for retrofitting (’961 Patent, col. 1:37-44).
- The Patented Solution: The invention integrates a camera assembly directly within the housing of a standard vehicle light, such as a marker or brake light. The camera body is concealed inside the colored vehicle lens, and its viewing axis is oriented at an angle through an opening in that lens (’961 Patent, col. 2:60-67; Fig. 2). This design is intended to be "unobtrusive in appearance" and allow for easier retrofitting by replacing an existing light assembly without significant modification to the vehicle body (’961 Patent, col. 1:52-55).
- Technical Importance: This approach provides a method for adding aftermarket safety cameras that are aesthetically integrated with the vehicle's original styling and are less conspicuous than externally mounted camera systems (’961 Patent, col. 1:37-44).
Key Claims at a Glance
- The complaint asserts infringement of "at least Claim 1" of the ’961 Patent (Compl. ¶25).
- Claim 1 was amended during a 2022 ex parte reexamination. The legally operative claim now includes several additional limitations.
- Essential elements of Amended Independent Claim 1:
- A vehicle lens of an external vehicle light, having an "internal reflector surface," a "translucent area," and an "opening in the translucent area."
- The vehicle lens has a "slanted surface in close proximity to the opening."
- A camera body is located "within the vehicle lens" with a viewing axis through the opening.
- A base is attached to the lens.
- The viewing axis is at an angle between 15 and 75 degrees relative to the plane of the base.
- A "camera assembly" that includes the camera body, a camera lens, and a transparent camera lens cover.
- The complaint reserves the right to assert additional claims (Compl. ¶25).
III. The Accused Instrumentality
Product Identification
- The accused products are Defendant’s "OEM Fit 3rd Brake Light Cameras," including, but not limited to, model numbers FLTW-7620, 9002-7607, and 9002-7608 (Compl. ¶8, ¶17).
Functionality and Market Context
- The complaint alleges these are vehicle camera systems designed to be integrated into the housing of an "external third brake light" (Compl. ¶25). The products are marketed and sold through Defendant’s website as aftermarket safety solutions (Compl. ¶16). The complaint includes a visual from a publicly available website, which shows a complete third brake light assembly with a red lens and a centrally located, integrated camera module (Compl. ¶17, Ex. B). The complaint alleges these products are commercially significant, as they are a "source of revenue and business focus" for the Defendant (Compl. ¶26).
IV. Analysis of Infringement Allegations
’961 Patent Infringement Allegations
| Claim Element (from Amended Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a vehicle lens of an external light for a vehicle light, the vehicle lens having a translucent area ... and having an opening in the translucent area of the vehicle lens | Defendant’s products provide "a vehicle lens for an external third brake light that has a translucent red vehicle lens" and "an opening in the vehicle lens." | ¶25 | col. 6:41-49 |
| the vehicle lens having a slanted surface in close proximity to the opening in the vehicle lens | The complaint does not provide sufficient detail for analysis of this element, as it was added to the claim after the complaint was filed. | N/A | col. 4:55-58 |
| a camera body within the vehicle lens having a viewing axis through the opening | The accused products have a "camera lens within the vehicle lens and having a viewing axis through the opening." | ¶25 | col. 6:49-50 |
| a base attached to the vehicle lens, wherein the viewing axis is at an angle between about 15 to 75 degrees with respect to a plane of the base | The accused products "include a base attached to the vehicle lens where the viewing axis is at an angle of between about 15 to 75 degrees with respect a plane of that base." | ¶25 | col. 6:50-54 |
- Identified Points of Contention:
- Scope Questions (Post-Reexamination): The complaint was filed before Claim 1 was amended. A central issue will be whether the accused products meet the new limitations added during reexamination, such as the "internal reflector surface" and the "slanted surface in close proximity to the opening." The complaint does not specifically allege the presence of these features.
- Technical Questions: What evidence will be presented to demonstrate that the accused camera assemblies are structurally equivalent to the claimed configuration? For instance, does the accused product's camera sit "completely within the vehicle lens," a feature emphasized in the patent's description (’961 Patent, col. 3:19-20), and how does that interact with the amended claim language?
V. Key Claim Terms for Construction
The Term: "slanted surface in close proximity to the opening"
Context and Importance: This limitation was added to amended Claim 1 during reexamination, presumably to distinguish the invention from prior art. Its construction will be critical for determining infringement, as the complaint does not contain allegations that map directly to this new element.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification describes various non-flat surfaces, including a "concave portion" (e.g., ’961 Patent, col. 3:20-21) and a "slanted top surface" (’961 Patent, col. 4:55-58), which could support an argument that the term encompasses a range of angled or curved surfaces near the camera opening.
- Evidence for a Narrower Interpretation: The figures depict specific geometries, such as the distinct angled top surface 221 in Figure 4. A party could argue the term should be limited to such explicit embodiments, rather than any surface that is merely non-parallel to the base.
The Term: "within the vehicle lens"
Context and Importance: This term defines the spatial relationship between the camera and the lens housing, which is core to the patent's goal of creating an "unobtrusive" device. The complaint alleges the accused camera is "within the vehicle lens" (Compl. ¶25).
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party might argue "within" simply means the camera body is located generally inside the outer bounds of the light housing.
- Evidence for a Narrower Interpretation: The specification states that in an embodiment, the "camera body 111 is completely within the vehicle lens 120" and "No part of the camera is outside of the vehicle lens 120" (’961 Patent, col. 3:19-20). This language could support a narrower construction requiring full enclosure, creating a potential point of dispute depending on the exact design of the accused products.
VI. Other Allegations
- Indirect Infringement: The complaint alleges induced infringement, stating that Defendant encourages and instructs its customers to use the accused products in an infringing manner through materials available on its websites, such as "information brochures" and "promotional material" (Compl. ¶26).
- Willful Infringement: The complaint does not allege pre-suit willfulness. It alleges that Defendant has knowledge of the patent "as early as the date of service of the Original Complaint" and that its continued infringement constitutes inducement (Compl. ¶26). This forms a basis for seeking enhanced damages for any post-filing infringement. The prayer for relief also requests a finding of an "exceptional case" to recover attorneys' fees (Compl. ¶31.E).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim scope following reexamination: Can Lexidine demonstrate that Brandmotion's products meet the new, more specific limitations added to Claim 1 during reexamination—particularly the "internal reflector surface" and "slanted surface"—which are not explicitly addressed in the original complaint?
- A key evidentiary question will be one of technical and structural proof: What evidence will be required to prove that the accused third brake light cameras, as sold and used, embody the specific angular relationships, component arrangements ("camera assembly"), and geometric features ("slanted surface") now required by the amended and legally operative patent claim?
