  • Defendant: The Partnerships and Unincorporated Associations Identified on Schedule “A” (Alleged to operate from the People's Republic of China or other foreign jurisdictions)
  • Plaintiff’s Counsel: Greer, Burns & Crain, Ltd.
• Case Identification: 1:23-cv-01592, N.D. Ill., 03/14/2023
• Venue Allegations: Venue is based on allegations that Defendants operate interactive e-commerce stores that directly target and make sales to consumers in the United States, including Illinois.
• Core Dispute: Plaintiff alleges that numerous unidentified e-commerce operators are making, using, selling, and importing hair styling products that infringe its U.S. design patent.
• Technical Context: The lawsuit concerns the high-end personal care appliance market, where unique and recognizable ornamental product design is a significant driver of brand value and market differentiation.
• Key Procedural History: The complaint is structured as an action against a group of unidentified defendants operating online storefronts. This procedural posture is common in anti-counterfeiting enforcement and suggests a primary objective may be to obtain injunctive relief to disable the accused e-commerce operations.

Case Timeline

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

U.S. Design Patent No. D853,642 - "HAIR STYLING AND HAIR CARE APPARATUS," issued July 9, 2019

The Invention Explained

• Problem Addressed: In the market for consumer appliances, establishing a distinct and recognizable product appearance is a key commercial challenge. The complaint asserts that Dyson products are known for their "unique and innovative design" which has become "enormously popular and even iconic" (Compl. ¶5).
• The Patented Solution: The patent does not protect a function, but rather the specific ornamental appearance of a hair styling apparatus. The claimed design is defined by the visual characteristics shown in the patent's drawings, including the device's overall elongated cylindrical form, the proportions of its handle and styling head, the specific fluted or vented appearance of the tip, the placement of controls, and the textured grip pattern near the power cord (D'642 Patent, FIGS. 1-7).
• Technical Importance: A distinctive ornamental design can serve as a strong source identifier for consumers, associating the product's appearance with the quality and innovation of a specific brand (Compl. ¶8).

Key Claims at a Glance

• The patent contains a single claim: "The ornamental design for a hair styling and hair care apparatus, as shown and described" (D'642 Patent, Claim).
• The complaint asserts this claim against the Defendants (Compl. ¶25).

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are "hair styling and hair care apparatus" that are sold by Defendants through various e-commerce storefronts and referred to in the complaint as the "Infringing Products" (Compl. ¶3).

Functionality and Market Context

The complaint alleges the accused products are "unauthorized and unlicensed" (Compl. ¶3). They are sold via e-commerce stores on platforms such as Amazon, eBay, AliExpress, and others, which are allegedly designed to appear to consumers as authorized retailers (Compl. ¶¶12, 15). The complaint alleges these products are the "same" as those embodying Dyson's patented design, thereby trading on Dyson's reputation and goodwill (Compl. ¶3). A perspective view of the patented design is shown in the complaint as FIG. 1 (Compl. p. 4).

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 to be the patented design. The complaint alleges that the accused products create a visual impression that is substantially the same as the patented design.

D'642 Patent Infringement Allegations

Identified Points of Contention

• Evidentiary Question: The central question for infringement will be a factual one: are the accused products sold by the Defendants visually, substantially the same as the claimed design from the perspective of an ordinary observer? The complaint does not contain side-by-side photographic comparisons of an actual accused product with the patent's figures, which would be necessary to resolve this question.
• Scope Questions: The scope of a design patent is defined by the solid lines in its drawings. A defense against infringement could arise if the accused products contain sufficient visual differences from the precise details depicted in the '642 patent's figures, such that an ordinary observer would not be deceived.

V. Key Claim Terms for Construction

In design patent litigation, the claim is typically construed by reference to the figures. The court does not construe claim terms in the same way as in utility patent cases, but rather describes the overall visual impression of the patented design.

• The Term: "The ornamental design for a hair styling and hair care apparatus, as shown and described."
• Context and Importance: This phrase constitutes the entirety of the claim, and its scope is defined by the patent's drawings. The construction of the design as a whole is the core of the case, as it will determine what features an ordinary observer would consider part of the protected design when comparing it to an accused product.
• Intrinsic Evidence for Interpretation: The intrinsic evidence consists solely of the seven figures in the patent.
  • Evidence for a Broader Interpretation: A party arguing for a broader interpretation would contend that the overall visual impression of the design as a whole is what is protected. This interpretation would focus on the general shape, proportions, and arrangement of major features, suggesting that minor variations in an accused product would not defeat an infringement claim (D'642 Patent, FIGS. 1-7).
  • Evidence for a Narrower Interpretation: A party arguing for a narrower interpretation would emphasize that the design is limited to the exact visual details shown in solid lines in the drawings. Any noticeable deviation in an accused product's proportions, surface ornamentation, or feature placement could be argued to place it outside the scope of the claim (D'642 Patent, FIGS. 1-7).

VI. Other Allegations

• Indirect Infringement: The complaint alleges that Defendants infringe "directly and/or indirectly" and are "working in active concert" (Compl. ¶¶ 21, 25). The prayer for relief seeks to enjoin aiding and abetting (Prayer ¶1(b)). These allegations suggest a potential theory that the network of unidentified sellers jointly infringes or that some entities within the network induce or contribute to the infringement of others.
• Willful Infringement: The complaint alleges that Defendants' infringement was willful (Compl. ¶22). This allegation is supported by claims that the Defendants operate "knowingly and willfully" and use tactics like multiple aliases and offshore accounts to conceal their identities and "continue operation in spite of Dyson's enforcement" (Compl. ¶¶ 20, 21).

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

• A central issue will be one of visual identity: Do the products actually sold by the Defendants possess an overall ornamental appearance that is substantially the same as the design claimed in the '642 patent? The resolution will depend on a factual comparison from the perspective of an ordinary observer, for which direct visual evidence of the accused products will be dispositive.
• The case also presents a significant procedural and enforcement challenge: Can the Plaintiff successfully identify the anonymous foreign operators behind the "Seller Aliases," establish personal jurisdiction, and effectively enforce any resulting judgment against entities that allegedly use tactics to evade legal accountability?
