  • Plaintiff’s Counsel: Greer, Burns & Crain, Ltd.
• Case Identification: 1:23-cv-04379, N.D. Ill., 07/07/2023
• Venue Allegations: Venue is based on allegations that Defendants target and conduct business with consumers in Illinois through interactive e-commerce stores, offer shipping to the state, and accept payment in U.S. currency.
• Core Dispute: Plaintiff alleges that Defendants’ unauthorized battery packs, sold through online marketplaces, infringe a U.S. design patent covering the ornamental design of a battery pack.
• Technical Context: The dispute is in the consumer electronics accessories market, where the aesthetic and ornamental design of components like battery packs can be a significant driver of brand recognition and consumer trust.
• Key Procedural History: The complaint is filed against a group of unidentified defendants, listed in a sealed "Schedule A," who are alleged to be a network of e-commerce operators. The complaint describes tactics allegedly used by such operators, including using multiple aliases and offshore accounts to evade enforcement, but does not mention prior litigation or IPR proceedings involving the asserted patent.

Case Timeline

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

U.S. Design Patent No. D710,299 - "Battery Pack"

The Invention Explained

• Problem Addressed: The complaint suggests that in the market for high-end consumer appliances, a distinctive product design is a key asset that consumers associate with quality and innovation (Compl. ¶¶ 5, 8). The challenge is to create an ornamental design for a functional component, such as a battery pack, that is instantly recognizable and reinforces the brand's aesthetic identity (Compl. ¶8).
• The Patented Solution: The patent protects the specific ornamental appearance of a battery pack (D’299 Patent, Claim). The design consists of a generally rectangular base with rounded ends, from which a complex, multi-tiered connector structure rises at an angle (D’299 Patent, FIG. 1, FIG. 4). The design includes specific visual features such as parallel recessed lines on the sides of the base, the particular shape of the connector housing, and the arrangement of surfaces on the top of the base (D’299 Patent, FIG. 6).
• Technical Importance: The complaint alleges that such distinctive designs are broadly recognized by consumers and are associated with the quality and innovation expected from the Dyson brand (Compl. ¶8).

Key Claims at a Glance

• The complaint asserts the single claim of the D'299 Patent.
• The claim is for "the ornamental design for a battery pack, as shown and described" (D’299 Patent, col. 1:40-41). The essential elements are the visual features depicted in the patent's drawings, including:
  • The overall configuration of a base unit and an angled, raised connector structure.
  • A rectangular base with rounded ends and parallel, horizontal indented lines on its longer sides.
  • A multi-faceted central connector tower with a specific arrangement of angled and vertical surfaces.
  • The top-down profile showing the relationship between the base and the connector structure.

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are "unauthorized and unlicensed" battery packs, referred to as the "Infringing Products" (Compl. ¶3).

Functionality and Market Context

The complaint alleges these are replacement battery packs for products such as Dyson vacuums (Compl. ¶5). They are sold by the defendant entities through various e-commerce marketplaces, including Amazon, eBay, AliExpress, and others (Compl. ¶12). The complaint alleges these online stores are designed to appear as authorized retailers to consumers, using content and images that make it difficult to distinguish them from genuine channels (Compl. ¶15). The complaint includes a perspective drawing from the patent, FIG. 1, to illustrate the "Dyson Design" allegedly embodied by the Infringing Products (Compl. p. 4, FIG. 1).

IV. Analysis of Infringement Allegations

The infringement test for a design patent is 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 alleges the Infringing Products are "the same product that infringes directly and/or indirectly the Dyson Design" (Compl. ¶21).

D'299 Patent Infringement Allegations

• Identified Points of Contention:
  • Factual Question: A primary issue will be an evidentiary one: demonstrating that the specific products sold by the unidentified "Schedule A" defendants are, in fact, substantially the same in appearance as the design claimed in the D'299 Patent. The standard is whether the resemblance is sufficient to deceive an ordinary observer.
  • Scope Question: A potential dispute may arise over whether certain elements of the battery pack's design are dictated by function rather than ornament. A defendant could argue that features like the shape of the connector or the placement of vents are functional and should therefore be disregarded or given less weight in the infringement analysis, potentially narrowing the scope of the protected design.

V. Key Claim Terms for Construction

In design patent litigation, formal claim construction is rare. The analysis centers on the scope of the design as a whole, as depicted in the drawings.

• The Term: "The ornamental design ... as shown"
• Context and Importance: The central issue in a design patent case is the scope of the claimed design. Practitioners may focus on this concept because the ultimate infringement question depends on a comparison between the patented design as a whole and the accused product. A key aspect of defining this scope is determining what is claimed versus what is disclaimed or purely functional.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent claims the design "as shown and described" (D’299 Patent, col. 1:40-41). The figures use solid lines for all features, and the specification explicitly states that only features in broken lines are disclaimed (D’299 Patent, col. 1:57-60). Since no broken lines are used, this suggests the entire visual appearance of the depicted battery pack is part of the claimed ornamental design.
  • Evidence for a Narrower Interpretation: A party could argue that some features are dictated by their function (e.g., the shape of the part that slides into the vacuum cleaner, the position of electrical contacts). While the patent does not disclaim these features, a court could potentially consider arguments that the scope of protection for functional elements is thin, focusing the "ordinary observer" test on the more purely aesthetic aspects of the design.

VI. Other Allegations

• Indirect Infringement: The complaint alleges Defendants are "working in active concert" and "jointly and severally" infringing the patent (Compl. ¶21). The prayer for relief also seeks to enjoin Defendants from "aiding, abetting, contributing to, or otherwise assisting" in infringement, which lays the groundwork for a theory of indirect infringement (Compl. p. 13, ¶1(b)).
• Willful Infringement: Willfulness is explicitly alleged (Compl. ¶22). The factual basis is the allegation that Defendants are part of a sophisticated network of infringers who knowingly and intentionally use tactics like multiple aliases and participation in online forums to evade detection and enforcement by rights holders (Compl. ¶¶17, 19, 21).

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

• A core issue will be one of proof and identity: Can the Plaintiff successfully link the anonymous "Schedule A" defendants to the sale of specific accused products and then demonstrate, through visual evidence, that those products are substantially the same as the patented design from the perspective of an ordinary observer?
• A second key question will be one of design scope: Will the court consider potential arguments that certain features of the claimed design are primarily functional, thereby narrowing the scope of protection and requiring a closer identity between the purely ornamental features of the patented design and the accused products?
• Finally, the case presents a significant remedial challenge: Given the alleged nature of the defendants as a diffuse network of foreign e-commerce operators, a central question will be the practical enforceability of any injunction and the effectiveness of extending that relief to the third-party online marketplace platforms where the products are sold.
