- Parties & Counsel:
- Plaintiff: Lexidine, LLC (Oklahoma)
- Defendant: Vision Tech America, Inc. (California)
- Plaintiff’s Counsel: Law Offices of Marc Libarle; Rozier Hardt McDonough PLLC
- Case Identification: 2:23-cv-01099, C.D. Cal., 02/14/2023
- Venue Allegations: Plaintiff alleges venue is proper in the Central District of California because Defendant is a California corporation with its principal place of business in the district, conducts substantial business in the district, and has committed the alleged acts of infringement there.
- Core Dispute: Plaintiff alleges that Defendant’s "BOYO" brand brake light cameras infringe a patent related to vehicle cameras integrated within vehicle light housings.
- Technical Context: The technology involves embedding cameras into aftermarket vehicle light assemblies, such as third brake lights, to provide drivers with visibility of blind spots in a manner that is aesthetically integrated and easier to retrofit than standalone cameras.
- Key Procedural History: The patent-in-suit, U.S. Patent No. 7,609,961, underwent an ex parte reexamination, resulting in a certificate issued on August 22, 2022. This proceeding amended the asserted independent claim (Claim 1) by adding several new limitations. The confirmation of the patent’s validity by the USPTO post-reexamination, albeit in an amended form, may be presented by the Plaintiff as evidence of the patent's strength.

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 describes prior art aftermarket vehicle cameras as being visually "obtrusive," which makes them a likely target for theft and detracts from the vehicle's original styling. Furthermore, installing these cameras often requires drilling holes into the vehicle body, complicating the retrofitting process. (’961 Patent, col. 1:36-44).
- The Patented Solution: The invention solves this by integrating a camera assembly directly into the housing of a standard vehicle light, such as a side marker or brake light. The camera is positioned inside the vehicle light’s lens, with its viewing axis pointing out through an opening. This allows the camera to be concealed within a functional, stock-appearing part, simplifying installation by replacing an existing light assembly rather than modifying the vehicle body. (’961 Patent, Abstract; col. 2:58-64; Fig. 3).
- Technical Importance: This approach provides a discreet and integrated method for retrofitting vehicles with cameras, which was an improvement over bulky, conspicuous add-on units of the time. (’961 Patent, col. 1:53-55).
Key Claims at a Glance
- The complaint asserts at least independent claim 1. As a result of reexamination, this claim was amended and is now narrower than the original.
- The essential elements of the amended independent claim 1 include:
- A vehicle lens for an external vehicle light, which has an "internal reflector surface," a "translucent area of a predetermined color," and an "opening" in the translucent area.
- The vehicle lens also has a "slanted surface in close proximity to the opening."
- A "camera body" located "within the vehicle lens" with a viewing axis through the opening.
- A "base" attached to the vehicle lens.
- The camera's "viewing axis is at an angle between about 15 to 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, where at least a portion of the assembly is "outside the opening," and the assembly is "fixed in position."
(’961 Patent, Reexam. Cert., col. 2:24-44).
III. The Accused Instrumentality
Product Identification
- The complaint accuses certain "brake light cameras" sold under Defendant's "BOYO" brand. Representative products identified include the BOYO VTS20, VTS40, and VTS50. (Compl. ¶¶17, 19).
Functionality and Market Context
- The accused products are aftermarket camera systems designed to replace a vehicle's factory third brake light housing. They integrate a camera into the brake light assembly itself to provide a rear view for the driver. (Compl. ¶27). The complaint provides visual evidence from the Defendant's website. For example, Exhibit G provides a product image of the BOYO VTS20, showing a red, translucent third brake light assembly with a small camera lens integrated into the housing. (Compl. Ex. G, p. 84).
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 of a predetermined color... and having an opening in the translucent area... | The accused products are a "vehicle camera that includes a vehicle lens for an external third brake light that has a translucent red vehicle lens that allows light transmission" and has "an opening in the vehicle lens." | ¶27 | col. 4:42-50 |
| the vehicle lens having a slanted surface in close proximity to the opening in the vehicle lens | The complaint does not specifically address this limitation, alleging more generally that the products infringe the patent claims. | ¶27 | 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." | ¶27 | col. 3:6-9 |
| 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." | ¶27 | col. 4:65-5:8 |
| a camera assembly that includes at least the camera body... wherein at least a portion of the camera assembly is outside the opening in the vehicle lens | The accused products have a camera lens that may "protrude through the vehicle lens or be placed outside the vehicle lens." | ¶27 | col. 2:58-62; col. 3:19-21 |
Identified Points of Contention
- Scope Questions: The infringement allegations in the complaint are general and appear to map to the original, broader version of Claim 1. A primary point of contention will be whether the accused products meet the specific limitations added during reexamination, such as the "internal reflector surface" and the "slanted surface in close proximity to the opening." The complaint does not provide specific facts to support infringement of these new, narrower limitations.
- Technical Questions: What evidence does the complaint provide that the viewing axis of the accused cameras is angled "between about 15 to 75 degrees" relative to the base? The complaint asserts this as a fact, but the basis for this specific angular range is not detailed, raising an evidentiary question that will likely be explored in discovery.
V. Key Claim Terms for Construction
The Term: "slanted surface in close proximity to the opening"
- Context and Importance: This phrase was added to Claim 1 during reexamination and was likely critical to overcoming a prior art rejection. Its interpretation will be central to the infringement analysis. Practitioners may focus on this term because the complaint's allegations do not specifically address it, suggesting it may be a point of non-infringement for the defense.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent specification does not provide an explicit definition for "slanted" or "close proximity," which could support giving the terms their plain and ordinary meaning, allowing for some flexibility in shape and distance.
- Evidence for a Narrower Interpretation: The specification describes an embodiment with a "slanted top surface 221" that is adjacent to a "concave portion 222" containing the opening. A defendant may argue that the term should be limited to this specific configuration shown in Figures 4 and 5. (’961 Patent, col. 4:55-64).
The Term: "internal reflector surface"
- Context and Importance: This term was also added during reexamination to narrow the claim. The infringement case hinges on whether the accused products, which are primarily brake light housings, contain a structure that meets this definition.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification states that a lens "can also be a reflector by having an interior surface or surfaces of the vehicle lens 120 contoured to reflect ambient light." (’961 Patent, col. 3:15-19). This language could support an argument that any contoured internal surface that reflects light qualifies.
- Evidence for a Narrower Interpretation: A defendant may argue that "reflector surface" implies a surface specifically designed for reflection (e.g., with reflective facets or coating), not merely the smooth, colored plastic interior of a standard light housing that passively reflects some light.
VI. Other Allegations
- Indirect Infringement: The complaint alleges inducement, stating that Defendant instructs and encourages its customers to use the products in an infringing manner through its website, information brochures, and promotional materials. (Compl. ¶28).
- Willful Infringement: The complaint alleges willfulness based on two grounds: (1) post-suit knowledge, asserting Defendant was aware of the patent "at least as of the date when it was notified of the filing of this action" (Compl. ¶29); and (2) pre-suit willful blindness, alleging Defendant has a "policy or practice of not reviewing the patents of others" (Compl. ¶30).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of evidentiary proof: Can the Plaintiff demonstrate that the accused BOYO brake light cameras meet the specific, narrowing limitations added to Claim 1 during reexamination, particularly the "internal reflector surface" and the "slanted surface in close proximity to the opening," which are not explicitly described in the complaint's infringement allegations?
- A second key issue will be one of claim construction: The dispute will likely focus on the proper scope of the terms added during reexamination. Can the term "internal reflector surface" be construed to read on the inner wall of a standard plastic brake light housing, and what specific geometry and distance are required by a "slanted surface in close proximity to the opening"? The court’s interpretation of these phrases may be dispositive of infringement.
