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: The complaint suggests the patent addresses the need to create a unique and innovative ornamental design for a hair styling product that is "instantly recognizable" to consumers in the marketplace (Compl. ¶5).
  • The Patented Solution: The patent protects the specific, non-functional visual appearance of a hair styling apparatus. The claimed design is characterized by a slender, cylindrical body that tapers to a working end with longitudinal grooves, a specific arrangement of recessed circular buttons on the main body, and a textured band at the base where the power cord attaches (D’642 Patent, FIGS. 1-7).
  • Technical Importance: The complaint alleges that this distinctive design is "iconic" and has become a symbol of quality and innovation that consumers associate with the Dyson brand (Compl. ¶5).

Key Claims at a Glance

  • The patent contains a single claim for "the ornamental design for a hair styling and hair care apparatus, as shown and described" (D’642 Patent, Claim). The scope of this claim is defined by the seven figures included in the patent.

U.S. Design Patent No. D852,415 - “Hair styling and hair care apparatus,” issued June 25, 2019

The Invention Explained

  • Problem Addressed: As with the '642 Patent, this design patent seeks to protect a distinctive aesthetic for a hair care appliance to distinguish it from other products (Compl. ¶8).
  • The Patented Solution: The patent protects the ornamental design for what appears to be the handle portion of a hair styling apparatus. The design features a generally cylindrical body, a specific layout of two circular buttons, a textured grip section at the base, and a perforated front face, as depicted in the patent's figures (D’415 Patent, FIGS. 1-7).
  • Technical Importance: The complaint alleges that this design is one of the "distinctive patented designs" for which Dyson products are known and which are associated with the quality and innovation expected from the brand (Compl. ¶8).

Key Claims at a Glance

  • The patent contains a single claim for "the ornamental design for a hair styling and hair care apparatus, as shown and described" (D’415 Patent, Claim). The scope is defined by the patent's seven figures.

III. The Accused Instrumentality

  • Product Identification: The accused products are identified as "hair styling and hair care apparatus" sold by Defendants and referred to as the "Infringing Products" (Compl. ¶3).
  • Functionality and Market Context: The complaint alleges that Defendants sell these products through numerous e-commerce stores operating under various "Seller Aliases" on platforms such as Amazon, eBay, AliExpress, and Temu (Compl. ¶12). It is alleged that these online stores are designed to appear as authorized retailers and that the products themselves bear designs that are confusingly similar to Dyson's patented designs, making it difficult for consumers to distinguish them from genuine Dyson products (Compl. ¶15). A representative image of the patented design claimed in the '642 patent is included in the complaint. (Compl. p. 4, FIG. 1).

IV. Analysis of Infringement Allegations

For design patents, infringement is determined not by a textual element-by-element comparison but by a visual comparison under the "ordinary observer" test. The complaint does not contain a formal claim chart.

  • Narrative Summary of Infringement: The complaint alleges that the "Infringing Products" sold by the Defendants embody ornamental designs that are substantially the same as those claimed in the '642 and '415 patents (Compl. ¶¶ 3, 25). The core of the allegation is that an ordinary observer would be deceived by the similarity in appearance, leading them to purchase an accused product under the belief that it is one of Dyson's products (Compl. ¶15). The complaint presents figures from the asserted patents, such as the perspective view of the design claimed in the '415 patent, as the "Dyson Designs" that are being infringed (Compl. p. 6, FIG. 1).
  • Identified Points of Contention:
    • Visual Similarity: A central question for the court will be whether an ordinary observer, giving such attention as a purchaser usually gives, would find the accused products' overall designs to be substantially the same as the designs claimed in the '642 and '415 patents. This analysis will involve comparing the overall visual impression created by the products with the patented designs.
    • Scope of Protection: The infringement analysis will require distinguishing between the overall protected ornamental appearance and any purely functional elements of the design, which are not protected by a design patent. The court may need to consider the scope of the claimed designs in view of the prior art to determine the breath of protection.

V. Key Claim Terms for Construction

In design patent litigation, the claim is defined by the drawings rather than textual limitations. The primary analysis focuses on a visual comparison between the claimed design and the accused product. Therefore, claim construction of specific terms is not a central issue as it is in utility patent cases.

VI. Other Allegations

  • Indirect Infringement: The complaint includes a prayer for relief enjoining "aiding, abetting, contributing to, or otherwise assisting anyone" in infringing (Prayer ¶1(b)). The factual basis for this appears to be the act of importing and selling the products through online marketplaces, thereby placing them into the stream of commerce (Compl. ¶25).
  • Willful Infringement: The complaint alleges that Defendants' infringement was "knowingly and willfully" committed (Compl. ¶¶ 21, 22). This allegation is supported by claims that Defendants operate as a coordinated network using fictitious aliases, frequently changing storefronts, and employing other tactics to conceal their identities and evade enforcement, which suggests knowledge of the infringing nature of their conduct (Compl. ¶¶ 11, 17-19).

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

  • A core issue will be one of visual identity: will an ordinary observer, comparing the accused products with the drawings in the '642 and '415 patents, find the overall ornamental appearances to be substantially the same, thereby supporting a finding of infringement?
  • A primary practical challenge will be one of enforcement and attribution: can the plaintiff successfully demonstrate that the various "Seller Aliases" constitute an interrelated network of infringers, and can effective relief be fashioned against defendants who are alleged to be foreign, unidentified, and actively using tactics to evade jurisdiction?
  • A key damages question will be one of profit disgorgement: should infringement be found, can Dyson prove the total profit realized by the Defendants from the sale of the infringing products, a remedy available for design patent infringement under 35 U.S.C. § 289, particularly given the allegation that Defendants move funds to offshore accounts to avoid payment (Compl. ¶20)?
