IV. Analysis of Infringement Allegations

The complaint references, but does not include, claim chart exhibits for its infringement allegations Compl. ¶32 Compl. ¶40 The narrative infringement theory is summarized below. No probative visual evidence provided in complaint.

[D749,997](https://ai-lab.exparte.com/patent/D749997) Infringement Allegations

The complaint alleges that Part No. GM1103180DSC directly infringes the ’997 Patent Compl. ¶32 The core of the allegation rests on the legal standard for design patent infringement, known as the "ordinary observer" test Compl. ¶22 Plaintiff asserts that, in the eye of an ordinary observer, the design of the accused rear bumper is "substantially the same as" the design claimed in the ’997 Patent, and that the resemblance is close enough to deceive an observer into purchasing the accused product Compl. ¶22; Compl. ¶32

[D792,815](https://ai-lab.exparte.com/patent/D792815) Infringement Allegations

Similarly, the complaint alleges that Part No. GM1002861DSC directly infringes the ’815 Patent under the "ordinary observer" test Compl. ¶40 Plaintiff contends that the overall ornamental appearance of the accused front bumper is "substantially similar" to the patented design, such that an ordinary purchaser would be deceived by the resemblance Compl. ¶22; Compl. ¶40

Identified Points of Contention

• Scope Questions: A central question for the court will be the application of the "ordinary observer" test to each accused part. This analysis will involve comparing the patented design to the accused product and assessing whether alleged differences are minor enough that the overall visual impression remains substantially the same.
• Technical Questions: A common defense in design patent cases involving replacement parts is that the design is dictated by its function—namely, to fit and match the vehicle for which it is a replacement. This raises the question of whether the features claimed in Plaintiff's patents are primarily ornamental, as required for design patent protection, or primarily functional, which would render the patents invalid or not infringed. The complaint does not provide sufficient detail for analysis of this potential point of contention.

V. Key Claim Terms for Construction

For design patents, claim construction focuses on the scope of the claimed design as a whole, rather than on discrete textual terms.

• The Term: "as shown and described"
• Context and Importance: This phrase, part of every design patent claim, defines the scope of protection. Its construction is critical because it ties the legal protection directly and exclusively to the ornamental features depicted in the patent's drawings. Practitioners may focus on this "term" to argue about what specific visual elements are, or are not, part of the claimed design.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: A party might argue for a broader scope by focusing on the overall visual impression and general configuration of the design, suggesting that minor variations in surface detail do not escape infringement so long as the overall aesthetic is copied.
  • Evidence for a Narrower Interpretation: A party might argue for a narrower scope by emphasizing the precise contours and details shown in solid lines. Furthermore, the use of broken lines to disclaim portions of the article (e.g., ’997 Patent, description; ’815 Patent, description) explicitly limits the claimed design. Arguments for a narrower interpretation will likely focus on these disclaimed elements and any subtle differences in the details that are claimed.

VI. Other Allegations

Indirect Infringement

• The complaint alleges both induced infringement under 35 U.S.C. § 271(b) and contributory infringement under § 271(c) Compl. ¶¶21, 23-25
  • The inducement claim is based on allegations that Defendant's software platform connects repair shops with distributors of infringing parts, thereby actively encouraging the importation, use, and sale of those parts Compl. ¶23
  • The contributory infringement claim is based on allegations that Defendant is involved in selling or offering to sell components of the accused products, knows them to be "especially made and especially adapted for use in each claimed design," and knows there is "no substantial non-infringing use" for them Compl. ¶25

Willful Infringement

• The complaint alleges willful infringement based on Defendant’s alleged pre-suit knowledge of the asserted patents Compl. ¶33 Compl. ¶41 This knowledge is predicated on Plaintiff's compliance with patent marking provisions, which includes listing the patents on a public website Compl. ¶17 The complaint alleges Defendant "disregarded an objectively high likelihood of infringement" Compl. ¶33

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

This case appears poised to revolve around three central questions for the court's determination:

1. Liability for Platform-Based Sales: A primary legal issue will be one of third-party liability: does Defendant's operation of a software platform that connects independent sellers and buyers of allegedly infringing "copy parts" constitute direct, induced, or contributory patent infringement?
2. The Scope of Ornamental Design: A key factual question will be the application of the ordinary observer test to each accused part. The outcome will depend on whether the court finds the accused products "substantially the same" as the patented designs, a determination that is highly dependent on visual comparison.
3. The Functionality Doctrine: A likely point of contention will be the distinction between ornamental and functional features. The case may turn on whether the designs of the asserted patents are primarily dictated by their function as vehicle replacement parts, which could present a significant challenge to Plaintiff's infringement claims.
