III. The Accused Instrumentality

Product Identification

The complaint identifies the "AOSU Video Doorbell Ultra/Outdoor Doorbell Camera Wireless 5MP" as infringing the D'918 Patent and the "AOSU Solar Wall Light Cam Pro" as infringing the D'022 Patent Compl. ¶82 Compl. ¶83 These and similar devices are collectively referred to as "Infringing Products" Compl. ¶84

Functionality and Market Context

The accused products are smart home security devices, including video doorbells and security cameras, sold by Defendants under the "aosu" brand Compl. ¶9 Compl. ¶19 The complaint alleges these products are sold through numerous online and physical retail channels, including Amazon.com, Walmart.com, and Menards, placing them in direct competition with Anker's Eufy products Compl. ¶¶72-76 Anker alleges that Defendants have "systematically copied Anker's brand" Compl. ¶77 and "replicated the distinctive design and overall aesthetic" of its products Compl. ¶78 The complaint provides visual evidence of an Amazon.com order detail page for an infringing video doorbell sold to a customer in Cicero, Illinois, which is used to support allegations of sales within the district Compl. ¶11

IV. Analysis of Infringement Allegations

The complaint alleges infringement of design patents, for which the legal standard is the "ordinary observer" test. This test asks whether an ordinary observer, familiar with the prior art, would be deceived into purchasing the accused product believing it is the patented design. The complaint presents its infringement theory primarily through narrative and side-by-side visual comparisons rather than a traditional utility patent claim chart.

The complaint alleges that, to an ordinary observer, the accused products embody the patented designs or a "colorable imitation thereof" Compl. ¶117 Compl. ¶125 To support this, the complaint provides direct visual comparisons. For the D'918 Patent, a figure juxtaposes the patent drawing with a photograph of the accused AOSU Video Doorbell Ultra, inviting a comparison of their overall vertical form, rounded shape, and placement of the camera and button Compl. ¶82, p. 26 Similarly, for the D'022 Patent, a figure places the patent drawing next to a photograph of the accused AOSU Solar Wall Light Cam Pro, highlighting alleged similarities in the boxy, angled housing and the arrangement of the lens and light elements Compl. ¶83, p. 26 The complaint also presents extensive side-by-side comparisons of the parties' marketing materials, alleging that Defendants copied Anker's "highly original and creative product photography and promotional materials" to further associate the products in consumers' minds Compl. p. 24

Identified Points of Contention

  • Scope Questions: A central issue will be whether the overall visual impression of the accused products is "substantially the same" as the patented designs. The court's analysis will likely weigh the similarities in overall shape and feature arrangement against differences in surface ornamentation, branding (e.g., the "aosu" logo on the accused products), and proportions.
  • Technical Questions: While not a utility case, the factual inquiry will involve a detailed visual comparison. A question for the fact-finder may be whether the visual effect of the differences between the designs is significant enough to be noticed by an ordinary purchaser, or if those differences are minor variations that do not alter the substantially similar overall appearance.

V. Key Claim Terms for Construction

In design patent cases, there are no "terms" to construe in the traditional sense. Instead, the court construes the single claim ("The ornamental design for [the article] as shown and described") by describing the visual characteristics of the design depicted in the patent drawings. The scope of protection is a key issue for the court to determine as a matter of law.

The "Claim" (D'918 Patent - Doorbell)

The scope of the claim is the overall ornamental design of the doorbell shown in the patent's figures.

  • Context and Importance: The definition of the design's scope is critical. A broader interpretation focusing on the overall arrangement of a rectangular body with a top-mounted circular camera and a bottom-mounted circular button would make an infringement finding more likely. A narrower interpretation emphasizing the specific proportions, the curvature of the edges, and the precise details of the camera lens assembly would make it easier for the accused design to be found distinct.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: Parties arguing for a broader scope may point to the overall visual impression created by the combination and placement of the primary design elements as depicted in the perspective and front views D'918 Patent, FIG. 1 D'918 Patent, FIG. 2
    • Evidence for a Narrower Interpretation: Parties arguing for a narrower scope may focus on specific, detailed features shown in solid lines, such as the exact chamfer on the edges, the cross-sectional profile, and the visual texture suggested within the camera element, as limitations on the design's scope D'918 Patent, FIG. 8 D'918 Patent, FIG. 9

The "Claim" (D'022 Patent - Camera)

The scope of the claim is the overall ornamental design of the wall-mounted camera shown in the patent's figures.

  • Context and Importance: The infringement analysis will depend on the court's construction of the claimed design's scope. Practitioners may focus on whether the core of the design is the general combination of a boxy housing with a wedge profile and a front-facing lens/light combination, or if it is limited to the exact angles and proportions shown.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The overall impression created by the angled top, the recessed camera panel, and the separation of the camera and light elements could be argued to define a broader design scope D'022 Patent, FIG. 1 D'022 Patent, FIG. 3
    • Evidence for a Narrower Interpretation: The precise angle of the top surface, the specific shape of the side profile, and the relative scale of the components as shown in the drawings could be cited as evidence that the design is limited to the exact embodiment depicted D'022 Patent, FIG. 5 D'022 Patent, FIG. 7

VI. Other Allegations

Indirect Infringement

The complaint alleges that Defendants indirectly infringe the patents by actively inducing infringement. This is based on allegations that Defendants induce retailers to sell the infringing products and induce end-users to use the products through product instructions and the "aosu" mobile application Compl. ¶120 Compl. ¶128

Willful Infringement

The complaint alleges willful infringement, asserting that Defendants were aware of the Eufy patents and associated products "since before they began selling Infringing Products" Compl. ¶85 The claim is further supported by allegations that Plaintiff provided Defendants with explicit notice of infringement through cease and desist letters in December 2025 Compl. ¶87 and service of the original complaint Compl. ¶88 The complaint seeks enhanced damages as a result Prayer for Relief ¶7

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

This case presents several key questions for the court, blending design patent law with broader claims of unfair competition.

  • A core issue will be one of aesthetic perception: Applying the ordinary observer test, are the accused "aosu" doorbell and camera designs substantially the same as Anker's patented designs? The outcome will depend on whether a fact-finder perceives the overall visual similarities as outweighing any minor differences in proportion, branding, or surface detail.
  • A second key question relates to the scope of the design patents: How will the court construe the scope of the claimed ornamental designs? A construction that focuses on the overall visual gestalt may favor the plaintiff, while a construction that emphasizes specific, detailed features as limitations could create a path for the defendants to argue their designs are different enough to be non-infringing.
  • Finally, a broader question of intent and competitive conduct underlies the entire dispute. The complaint's heavy emphasis on alleged systematic copying of Anker's marketing, trade dress, and "HOMEBASE" trademark (Compl. ¶77; Compl. ¶78; Compl. ¶79) suggests that the patent infringement claims are part of a larger narrative of unfair competition. How the court views the evidence of alleged copying in the trademark and marketing context may influence its perspective on the design patent claims.
