  • Plaintiff: Dyson Technology Limited (United Kingdom)
  • Defendant: [REDACTED] and The Individuals and Entities Operating [REDACTED] (People's Republic of China or other foreign jurisdictions)
  • Plaintiff’s Counsel: Greer, Burns & Crain, Ltd.
• Case Identification: 1:23-cv-02912, N.D. Ill., 05/11/2023
• 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 residents of Illinois.
• Core Dispute: Plaintiff alleges that numerous e-commerce operators are selling unauthorized hair styling appliances that infringe the ornamental design of Plaintiff's patented product.
• Technical Context: The lawsuit concerns the high-end personal hair care appliance market, where unique and recognizable product design is a significant aspect of brand identity and market value.
• Key Procedural History: The filing is an Amended Complaint against a collective of unidentified e-commerce sellers operating under various aliases.

Case Timeline

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

U.S. Design Patent No. D853,642 - Hair Styling and Hair Care Apparatus

The Invention Explained

• Problem Addressed: As a design patent, the '642 Patent addresses the ornamental, rather than functional, aspects of a product. The complaint frames the issue in commercial terms, asserting that Dyson products are known for "distinctive patented designs" which are "broadly recognized by consumers" and associated with "quality and innovation." (Compl. ¶8).
• The Patented Solution: The patent protects the specific visual appearance of a hair styling apparatus. The claimed ornamental design is characterized by an overall elongated, wand-like shape with a sleek cylindrical body, a tapered working end featuring multiple curved, longitudinal slots, a main body with two circular control buttons, and a distinct handle portion with a textured grip near the cord entry. (D’642 Patent, Figs. 1-7). The specific proportions and arrangement of these features constitute the patented design.
• Technical Importance: The complaint alleges that the unique and innovative design of Dyson products has made them "enormously popular and even iconic," serving to symbolize high quality to the purchasing public. (Compl. ¶5).

Key Claims at a Glance

• The patent asserts a single claim for "the ornamental design for a hair styling and hair care apparatus, as shown and described." (D’642 Patent, Claim).
• As a design patent, the claim is defined by the drawings. The core ornamental features comprising the claimed design include:
  • The overall elongated, cylindrical, wand-like form factor.
  • A tapered working end with multiple longitudinally-arranged, curved slots.
  • A central body section featuring two distinct, spaced-apart circular control buttons.
  • A handle section adjacent to the power cord entry with a knurled or textured grip pattern.
  • The specific proportional relationships between the tapered end, central body, and handle.

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are "unauthorized and unlicensed" products, namely a "hair styling and hair care apparatus," which the complaint collectively terms the "Infringing Products." (Compl. ¶3).

Functionality and Market Context

The complaint alleges that Defendants operate numerous e-commerce stores under various "Seller Aliases" on platforms such as Amazon, eBay, AliExpress, and DHgate. (Compl. ¶12). These stores are allegedly designed to appear as authorized retailers to "unknowing consumers" and sell products that copy the patented "Dyson Design." (Compl. ¶¶ 3, 15). The complaint includes a perspective view of the patented design, which the Infringing Products are alleged to copy. (Compl. p. 4, FIG. 1).

IV. Analysis of Infringement Allegations

The complaint does not contain a detailed claim chart. Instead, it asserts that the Infringing Products are visually so similar to the patented design that they infringe. The legal test for design patent infringement is whether an "ordinary observer," giving such attention as a purchaser usually gives, would be deceived into purchasing the accused product, believing it to be the patented design.

The complaint alleges that Defendants make, use, sell, and import "the same unauthorized and unlicensed product" that infringes the '642 Patent. (Compl. ¶3). The complaint presents several views of the patented design, including a side view and end views, to establish the specific ornamental features at issue. (Compl. p. 5, FIG. 3; Compl. p. 6, FIGS. 4-5). The core of the infringement allegation is that the accused products embody an ornamental design that is substantially the same as the one depicted in these figures. (Compl. ¶25).

Identified Points of Contention

• Visual Comparison: The central issue for the court will be a direct visual comparison between the accused products and the drawings in the '642 Patent. The question is whether the designs are "substantially the same" from the perspective of an ordinary observer familiar with the prior art.
• Scope Questions: A potential issue in design patent cases is whether certain features of the design are primarily functional rather than ornamental. If a feature is dictated by its function, it is not protected by the design patent. The complaint does not raise this issue, but it could become a point of contention regarding elements like the shape and placement of the air vents on the apparatus head.

V. Key Claim Terms for Construction

In design patent litigation, the claim is understood to be the visual design embodied in the patent's drawings, and traditional claim construction of textual terms is rare. The analysis focuses on the overall visual impression of the design on an ordinary observer.

• The Term: "Hair Styling and Hair Care Apparatus"
• Context and Importance: This phrase from the patent's title and claim defines the article of manufacture to which the ornamental design is applied. Its construction defines the category of products to which the patent applies. For infringement to be found, an accused product must be a type of hair styling or hair care apparatus that incorporates the patented design.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The complaint does not provide evidence to support a particularly broad interpretation beyond the common understanding of the term.
  • Evidence for a Narrower Interpretation: The figures in the patent consistently show a wand-style apparatus, which could suggest the scope is limited to devices with this specific form factor. (D'642 Patent, Figs. 1-7). The complaint's allegations are directed at products that appear to share this same form factor. (Compl. ¶3; Compl. p. 4, FIG. 1).

VI. Other Allegations

Indirect Infringement

The complaint alleges that Defendants are "working in active concert" to infringe. (Compl. ¶21). The prayer for relief also seeks to enjoin "aiding, abetting, contributing to, or otherwise assisting anyone" in the infringing acts, which is language associated with claims for induced infringement. (Prayer for Relief ¶1(b)).

Willful Infringement

Willfulness is explicitly alleged. (Compl. ¶22). This allegation is supported by claims that Defendants intentionally copy an "iconic" design and engage in evasive tactics, such as operating under multiple aliases and communicating in online forums about evading detection and litigation, suggesting knowledge of Dyson's rights and an intent to infringe. (Compl. ¶¶ 5, 17-19).

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

• A core issue will be one of visual identity: Does a side-by-side comparison of the accused products and the '642 Patent drawings reveal a design that is "substantially the same" in the eyes of an ordinary observer? The outcome of the case will depend almost entirely on this factual, visual determination.
• A central challenge will be procedural and evidentiary: Given that the defendants are alleged to be a large, shifting collective of foreign-based online sellers, key questions will be whether the Plaintiff can successfully serve process, obtain jurisdiction, and ultimately enforce any judgment for damages or injunctive relief against these entities.
• A key question for damages will be the calculation of profits: The complaint seeks the defendants' total profits from infringement under 35 U.S.C. § 289. A significant evidentiary hurdle will be for the Plaintiff to prove the total profits attributable to the infringing sales made by a diffuse and allegedly evasive network of sellers.
