Lexidine LLC v. Yantech LLC
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Lexidine, LLC (Oklahoma)
- Defendant: Yantech, LLC (New York)
- Plaintiff’s Counsel: HENINGER GARRISON DAVIS, LLC
- Case Identification: 1:19-cv-02945, E.D.N.Y., 05/17/2019
- Venue Allegations: Venue is alleged to be proper in the Eastern District of New York because Defendant Yantech is organized in the district and has allegedly committed acts of infringement there.
- Core Dispute: Plaintiff alleges that Defendant’s OEM Fit 3rd Brake Light Cameras infringe a patent related to vehicle cameras integrated into light assemblies.
- Technical Context: The technology involves concealing vehicle backup or side-view cameras within standard light fixtures, such as brake lights or marker lights, to provide a less obtrusive, retrofittable safety solution.
- Key Procedural History: The complaint was filed in May 2019. Subsequent to the filing, the asserted '961 Patent underwent ex parte reexamination, resulting in a certificate issued in August 2022. This proceeding significantly amended the sole asserted independent claim, Claim 1, by adding several limitations, which will narrow the scope of the infringement inquiry for the court.

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 addresses the aesthetic and practical drawbacks of conventional aftermarket vehicle cameras. It notes that such cameras are often "obtrusive in appearance," can make a vehicle a target for theft, and typically require "drilling a hole in the vehicle" for installation ('961 Patent, col. 2:36-44).
- The Patented Solution: The invention proposes integrating a camera assembly entirely within the housing of a standard external vehicle light, such as a marker light or third brake light ('961 Patent, Abstract; Fig. 2). By placing the camera body "completely within the vehicle lens," the device is concealed, preserving the vehicle's original appearance and simplifying installation by using the existing mounting points of the light fixture ('961 Patent, col. 4:18-20; col. 3:53-60).
- Technical Importance: This design offered a method for adding safety cameras to vehicles in a way that was both aesthetically integrated and easier to retrofit compared to prior art solutions ('961 Patent, col. 2:51-55).
Key Claims at a Glance
The complaint asserts "at least Claim 1" of the '961 Patent (Compl. ¶21). It is critical to note that Claim 1 was substantively amended during an ex parte reexamination that concluded after the complaint was filed. The infringement analysis will be governed by the amended claim language from the Reexamination Certificate ('961 C1 Patent).
- Independent Claim 1 (as amended):
- A vehicle lens of an external light for a vehicle, the lens having an "internal reflector surface" and a translucent area of a predetermined color, with an opening in the translucent area.
- The vehicle lens also 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 vehicle lens.
- The camera's viewing axis is at an angle between about 15 to 75 degrees relative to a plane of the base.
- The device includes a "camera assembly" (comprising at least the camera body, a camera lens, and a transparent camera lens cover) that is fixed in position, with at least a portion of the assembly being outside the opening.
III. The Accused Instrumentality
Product Identification
- The accused products are "OEM Fit 3rd Brake Light Cameras," including, but not limited to, model numbers CCDIJOON15, REAMX5A249, VS601, and BR-RVC07-PE (Compl. ¶8).
Functionality and Market Context
- The complaint alleges these products are vehicle cameras integrated into a third brake light assembly (Compl. ¶21). They are advertised and sold through various channels, including Defendant's website, www.yantechusa.com (Compl. ¶17). The complaint references visual evidence in exhibits, which are described as showing offers for sale of these camera models (Compl. ¶16). For example, the complaint identifies one accused product via an exhibit described as an "Offer for Sale of Yantech's BR-RVC07-PE – Peugot Expert Van 3rd Brake Light Rear View Backup Camera Model" (Compl. p. 10, Ex. F).
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 of the vehicle lens | The Accused 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." | ¶21 | col. 6:41-47 |
| the vehicle lens having an internal reflector surface | The complaint does not provide sufficient detail for analysis of this element. | col. 7:10-14 | |
| 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. | col. 7:10-14 | |

Identified Points of Contention
- Evidentiary Questions: The most significant issue arises from the post-filing reexamination. The complaint's allegations are directed to the original, broader version of Claim 1. A central question for the court will be whether Plaintiff can produce evidence that the Accused Products meet the specific structural limitations added during reexamination, such as the "internal reflector surface" and the "slanted surface in close proximity to the opening," as these elements are not addressed in the complaint's narrative.
- Scope Questions: The infringement analysis will depend heavily on the interpretation of the claim language added during reexamination. For example, does the general description of a camera in a brake light housing (Compl. ¶21) provide sufficient factual basis to plausibly allege infringement of the newly-added, more specific "camera assembly" limitation?
V. Key Claim Terms for Construction
The Term: "internal reflector surface"
- Context and Importance: This term was added to Claim 1 during reexamination and is not present in the original claim asserted in the complaint. Its construction will be critical to determining the scope of the amended patent. Practitioners may focus on this term because it appears to be a key feature distinguishing the invention from prior art examined by the USPTO.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The term itself is not explicitly defined, which might support an argument that any internal surface of the lens housing capable of reflecting light meets the limitation.
- Evidence for a Narrower Interpretation: The specification describes this feature as an "interior surface or surfaces of the vehicle lens 120 contoured to reflect ambient light as the specific color," suggesting a purpose-built, functional surface rather than an incidental one ('961 Patent, col. 3:15-18).
The Term: "slanted surface in close proximity to the opening"
- Context and Importance: This limitation was also added during reexamination and introduces specific geometric requirements for the vehicle lens. The definition of "slanted" and the degree of "close proximity" will be central to the infringement analysis.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent shows various embodiments, and a party could argue that any surface that is not parallel or perpendicular to the base near the opening could be considered "slanted."
- Evidence for a Narrower Interpretation: A party may argue the term must be construed in light of specific embodiments, such as the "slanted top surface 221" which is shown as a distinct, angled plane on the lens housing ('961 Patent, Fig. 4; col. 4:54-58).
VI. Other Allegations
Indirect Infringement
- The complaint alleges that Defendant induces infringement by providing materials on its websites, such as "information brochures" and "promotional material," that allegedly "encouraged, instructed, enabled, and otherwise caused" customers to use the Accused Products in an infringing manner (Compl. ¶22).
Willful Infringement
- The complaint does not allege pre-suit knowledge of the '961 Patent. However, it alleges that Defendant's infringement has continued despite knowledge of the patent "as early as the date of service of the Original Complaint," which may form a basis for post-filing willfulness (Compl. ¶22).
VII. Analyst’s Conclusion: Key Questions for the Case
A core issue will be one of procedural impact and evidence: The complaint was filed against the original claims of the '961 Patent. However, the patent was substantially narrowed in a subsequent ex parte reexamination. A key question for the court will be whether Plaintiff's initial allegations provide a plausible basis for infringement of the amended claims, and what evidence it can marshal to prove the Accused Products meet the specific limitations added during reexamination, such as the "internal reflector surface" and "slanted surface."
A second central issue will be one of claim construction: The case will likely turn on the court's interpretation of the terms added to Claim 1 during reexamination. Can the term "internal reflector surface," for example, be construed to cover any generic internal surface of the lens housing, or does the specification require a specifically "contoured" surface designed for light reflection? The resolution of these construction disputes will likely be determinative of infringement.
