  • Defendant: Accele Electronics, Inc. (California)
  • Plaintiff’s Counsel: Insight, PLC
• Case Identification: 2:19-cv-09459, C.D. Cal., 11/04/2019
• Venue Allegations: Venue is alleged to be proper in the Central District of California because Defendant is incorporated in the district, maintains a regular and established place of business there, and has allegedly committed acts of infringement within the district.
• Core Dispute: Plaintiff alleges that Defendant’s aftermarket third brake light camera systems infringe a patent related to integrating a camera within a vehicle’s external light housing.
• Technical Context: The case concerns vehicle safety technology, specifically aftermarket camera systems designed to be retrofitted onto vehicles to provide a rearward view, addressing a significant consumer and commercial market for enhanced vehicle visibility.
• Key Procedural History: The complaint states that the patent-in-suit was invented by Mr. Eric Park, who owns 100% of Plaintiff Lexidine, LLC. The patent has been subject to several assignments between Mr. Park and Lexidine. Subsequent to the filing of this complaint, the patent underwent an ex parte re-examination, which concluded in 2022 with the issuance of a certificate confirming the patentability of amended claims. This proceeding narrowed the scope of the asserted independent claim, a factor that may be central to the litigation.

Case Timeline

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

• Patent Identification: U.S. Patent No. 7,609,961, "VEHICLE CAMERA", issued October 27, 2009.

The Invention Explained

• Problem Addressed: The patent's background describes conventional aftermarket vehicle cameras as being "obtrusive in appearance," obviously identifiable as cameras (which may encourage theft), and often requiring modifications to the vehicle like "drilling a hole" for installation (’961 Patent, col. 1:36-44).
• The Patented Solution: The invention solves these problems by integrating a camera assembly inside the housing of a standard vehicle light, such as a marker or brake light, to be both "unobtrusive in appearance" and "readily retrofitted" (’961 Patent, col. 1:52-55). The camera body is concealed within the light's colored, translucent lens, with its viewing axis angled to provide a useful field of view from the light's position on the vehicle (’961 Patent, Abstract; Fig. 3). This design aims to hide the camera from view while using the existing light fixture as a mounting point.
• Technical Importance: The technology provided a method for aesthetically integrating safety cameras into vehicles without altering the vehicle's original styling, a key consideration for aftermarket products (’961 Patent, col. 1:45-55).

Key Claims at a Glance

• The complaint asserts infringement of at least independent Claim 1 of the ’961 Patent (Compl. ¶21). It also reserves the right to assert other claims.
• The essential elements of the original Claim 1 asserted in the complaint are:
  • A vehicle lens of an external vehicle light, having a translucent area of a predetermined color and an opening in that translucent area.
  • A camera body located within the vehicle lens, having a viewing axis that passes 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 with respect to a plane of the base.

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 RVCEXP and RVCNV (the "Accused Products") (Compl. ¶¶8-9, 17).

Functionality and Market Context

• The Accused Products are described as aftermarket cameras integrated into the housing of a third brake light assembly (Compl. ¶¶8, 21). These products are designed to replace a vehicle's original third brake light, providing rear-view camera functionality without requiring separate installation of a standalone camera. The complaint includes images of the accused products, which appear to be complete third brake light assemblies with an integrated camera module, intended to replace original vehicle parts (Compl. ¶17, Ex. B-C).

IV. Analysis of Infringement Allegations

'961 Patent Infringement Allegations

Identified Points of Contention

• Impact of Re-examination: The complaint was filed in 2019, asserting the original version of Claim 1. However, a re-examination certificate issued in 2022 amended Claim 1, adding new limitations, including an "internal reflector surface" and a "slanted surface in close proximity to the opening" (’961 Re-exam Cert., col. 2:28-33). The central question for the case will be whether the Accused Products meet these new, narrower claim requirements, which were not part of the patent when the suit was initiated.
• Scope Questions: The complaint alleges that the camera lens may "protrude through the vehicle lens or be placed outside the vehicle lens" (Compl. ¶21). This raises a question of scope, as the patent specification emphasizes that the camera body is "completely within the vehicle lens" to "conceal the camera" (’961 Patent, col. 3:19-21). Whether a partially protruding camera infringes the claim term "camera body within the vehicle lens" will be a likely point of dispute.
• Technical Questions: The complaint makes a conclusory allegation that the viewing axis of the Accused Products meets the specific "15 to 75 degrees" angular limitation required by the claim (Compl. ¶21). A key evidentiary question is what proof exists to substantiate that the accused devices actually operate within this precise angular range.

V. Key Claim Terms for Construction

The Term: "camera body within the vehicle lens"

Context and Importance

This term is critical to the invention's core concept of being "unobtrusive" (’961 Patent, col. 1:54-55). Its construction will determine whether the claim requires the camera to be fully hidden or if some protrusion is permitted. Practitioners may focus on this term because the complaint's allegation of a protruding lens (Compl. ¶21) appears to conflict with the patent's repeated emphasis on concealment.

Intrinsic Evidence for Interpretation

• Evidence for a Broader Interpretation: A party might argue that the claim language itself does not include a modifier like "completely" or "entirely," and thus "within" could be construed more broadly to mean generally located inside the perimeter of the lens housing.
• Evidence for a Narrower Interpretation: The patent specification provides strong support for a narrower meaning, stating that "the camera body 111 is completely within the vehicle lens 120. No part of the camera is outside of the vehicle lens 120. Such a structure conceals the camera" (’961 Patent, col. 3:19-21). This language could be interpreted as a clear definition or a disavowal of claim scope.

The Term: "opening in the translucent area"

Context and Importance

This term defines the aperture through which the camera functions. Its construction is important, especially since the re-examination added a new limitation requiring a "slanted surface in close proximity to the opening" (’961 Re-exam Cert., col. 2:31-32). The definition of the "opening" is now directly linked to the geometry of its immediate surroundings.

Intrinsic Evidence for Interpretation

• Evidence for a Broader Interpretation: The original claim simply required an "opening," without specifying its shape, size, or surrounding features, which could support a broad interpretation covering any physical hole.
• Evidence for a Narrower Interpretation: The patent figures depict the opening as part of a "concave portion" of the lens housing (’961 Patent, Fig. 2, item 121). The addition of the "slanted surface" limitation during re-examination strongly suggests that the patentee intended to limit the claim to specific geometric configurations shown in the embodiments, narrowing the term's effective scope.

VI. Other Allegations

Indirect Infringement

• The complaint alleges induced infringement, stating that Defendant intentionally encourages and instructs its customers to use the Accused Products in an infringing manner through information available on its websites, brochures, and other promotional materials (Compl. ¶22).

Willful Infringement

• The complaint does not contain an explicit allegation of willful infringement or pre-suit knowledge of the patent. It alleges that Defendant's knowledge for the purpose of inducement began "as early as the date of service of the Original Complaint" (Compl. ¶22). However, the prayer for relief requests that the court declare the case "exceptional" and award attorneys' fees pursuant to 35 U.S.C. § 285 (Compl. ¶27.E).

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

• A dispositive issue will be the impact of the post-filing re-examination: Can the Plaintiff's infringement theory, developed for the original claims, survive against the amended and narrowed version of Claim 1? The case may turn on whether the accused products contain the specific "internal reflector surface" and "slanted surface" features added to the claim years after the complaint was filed.
• The case will also involve a fundamental question of definitional scope: How will the court construe the term "camera body within the vehicle lens"? The resolution of whether this term requires complete concealment, as suggested by the specification, or permits the partial protrusion alleged in the complaint, will be critical to the infringement analysis.
