II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,046,143 - "Caliper Cover"
- Patent Identification: U.S. Patent No. 9,046,143, "Caliper Cover," issued June 2, 2015.
The Invention Explained
- Problem Addressed: The patent's background section describes issues with existing vehicle brake calipers, including the ejection of unsightly brake dust and the difficulty of installing prior art caliper covers, which could require gluing or complete removal of the caliper from its mount ('143 Patent, col. 1:24-41).
- The Patented Solution: The invention provides a caliper cover assembly with a mounting system that allows for easy installation without special tools or dismounting the caliper from the vehicle. The system uses a specially designed clip that attaches to the caliper body, and a separate cover piece, which includes a mounting member, that is then fastened to the clip ('143 Patent, col. 1:53-60; FIG. 2). This design is intended to provide an aesthetic enhancement while also potentially directing airflow to cool the caliper ('143 Patent, col. 2:11-22).
- Technical Importance: The patented design offered a solution for automotive enthusiasts to customize their vehicles' appearance easily, avoiding the labor-intensive and potentially risky process of removing and reinstalling a critical brake component ('143 Patent, col. 2:26-30).
Key Claims at a Glance
- The complaint specifically identifies independent Claim 2 as infringed and reserves the right to assert other claims (Compl. ¶¶ 32, 35).
- The essential elements of independent Claim 2 are:
- A U-shaped clip with upper and lower members, installed above a brake rotor.
- The upper clip member has a slot extending along its length.
- A cover with a generally planar interior surface and a cover member extending away from it.
- The length of the cover and the length of the cover member are oriented "substantially perpendicular" to each other.
- A mounting member projecting from the cover member, which is sized to slide into the clip's slot.
- The mounting member, when engaged, projects above the top surface of the upper clip member.
- A fastener to engage the mounting member and bias the cover member against the clip, securing the assembly.
III. The Accused Instrumentality
Product Identification
- The accused instrumentalities are various models of caliper covers sold by Defendant, identified by a list of over a dozen stock keeping units (SKUs), such as 71100A, 71106A, and 71108 (collectively, the "Accused Products") (Compl. ¶25).
Functionality and Market Context
- The complaint alleges the Accused Products are caliper covers that practice the patented technology (Compl. ¶24). They are promoted and sold to end-users through Defendant's commercial website (Compl. ¶8). The complaint further alleges that Defendant provides installation instructions that direct customers to install and use the Accused Products in an infringing manner (Compl. ¶26).
IV. Analysis of Infringement Allegations
The complaint alleges infringement of at least Claim 2 of the '143 Patent and incorporates by reference an exemplary claim chart (Exhibit 19) that was not included with the public filing (Compl. ¶¶ 32, 36). The infringement theory is that the Accused Products, when installed according to Defendant's instructions, contain all the structural elements recited in the claim. No probative visual evidence provided in complaint.

- Identified Points of Contention:
- Scope Questions: A potential dispute may arise over the meaning of "substantially perpendicular." The parties may contest the degree of angular deviation permitted by this term and whether the accused design falls within that scope.
- Technical Questions: A central factual question will be whether the components of the Accused Products and their method of assembly correspond to the specific structural limitations of the claim. The complaint's lack of detailed, public-facing technical evidence for infringement suggests that discovery will be necessary to determine the precise construction of the Defendant's products.
V. Key Claim Terms for Construction
The Term: "a clip"
Context and Importance: This term defines the primary component that interfaces with the vehicle's caliper. Its construction is central to the patent's claimed benefit of easy installation. Practitioners may focus on this term to determine if it is limited to the specific sheet-metal embodiment shown in the patent's figures or if it can read on a wider variety of fastening hardware.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claims describe the clip functionally by its "substantially a U-shape" and its installation location "above a brake rotor" ('143 Patent, col. 4:24-30), which could support an interpretation covering any component that meets these general structural and positional requirements.
- Evidence for a Narrower Interpretation: The detailed description explains that the clip "fits in-between the two opposing brake pads" ('143 Patent, col. 3:24-26). A defendant could argue this language limits the scope of "a clip" to only those designs that are installed in this specific manner, as depicted in FIG. 1.
The Term: "cover member"
Context and Importance: The claim requires a "cover" and a "cover member" that are oriented "substantially perpendicular" ('143 Patent, col. 4:40-42). The definition of "cover member" as distinct from the "cover" is critical to this structural limitation.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification describes the "cover member" (20) as that which "supports the caliper cover 22" ('143 Patent, col. 3:19-20). This functional language could be argued to apply to any structural element that serves as the mounting base for the visible cover plate.
- Evidence for a Narrower Interpretation: The figures consistently depict the "cover" (22) and "cover member" (part of 20) as distinct parts joined at a sharp angle ('143 Patent, FIG. 2). A defendant might argue this requires two discrete, planar components and does not read on a single, continuously curved or integrally formed piece of material.
VI. Other Allegations
- Indirect Infringement: The complaint alleges induced infringement, asserting that Defendant's "website, product documentation, [and] installation instructions" actively encourage and instruct customers to assemble the Accused Products in a way that infringes the '143 Patent (Compl. ¶¶ 26, 39). It also pleads contributory infringement, alleging the Accused Products are not staple articles of commerce suitable for substantial non-infringing use (Compl. ¶41).
- Willful Infringement: The willfulness claim is based on alleged pre-suit knowledge. The complaint alleges that Plaintiff provided Defendant with actual notice of the '143 Patent and the alleged infringement via a letter dated August 19, 2022, and that Defendant continued its accused activities thereafter (Compl. ¶¶ 27-29, 43).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim construction: Can the term "substantially perpendicular," which describes the orientation of the "cover" and "cover member," be construed broadly to cover designs that are not a strict right angle, or will it be limited by the embodiments depicted in the patent's figures?
- A second central issue will be one of structural correspondence: As a factual matter, do the components of the Accused Products, particularly their clip and cover assembly, contain every element as recited in Claim 2? The resolution will depend on evidence developed during discovery regarding the precise design and assembly of Defendant's products.
