• Case Identification: 1:23-cv-01721, N.D. Ill., 03/20/2023
• Venue Allegations: Venue is alleged to be proper based on Defendants targeting business activities, including sales, toward consumers in Illinois through interactive e-commerce stores.
• Core Dispute: Plaintiff alleges that Defendants’ unauthorized hair dryers, sold through various online marketplaces, infringe a U.S. design patent covering the ornamental appearance of Plaintiff's hair dryer.
• Technical Context: The dispute centers on the unique and non-functional ornamental design of a high-end hair care appliance in the consumer electronics market.
• Key Procedural History: The complaint is structured as a "Schedule A" action against numerous unidentified e-commerce operators. This procedural posture is often used to combat widespread online sale of allegedly counterfeit or infringing goods by difficult-to-identify foreign entities, with the complaint alleging that Defendants use fictitious aliases and offshore accounts to conceal their identities and evade enforcement.

Case Timeline

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

U.S. Design Patent No. D715,996 - "HAIR DRYER"

• Patent Identification: U.S. Design Patent No. D715,996, "HAIR DRYER," issued October 21, 2014.

The Invention Explained

• Problem Addressed: Design patents protect the novel, ornamental, and non-functional aspects of an article of manufacture rather than a technical problem. The complaint asserts that Dyson developed a "unique and innovative design" intended to be "instantly recognizable" to consumers (Compl. ¶5).
• The Patented Solution: The patent claims the specific ornamental design for a hair dryer. The visual appearance is characterized by a short, wide cylindrical head mounted perpendicularly atop a long, slender cylindrical handle. Key features of the claimed design include the open-ring structure of the nozzle and a distinct textured cap at the base of the handle where an air filter is typically located ('996 Patent, FIGS. 1-7). The complaint refers to this as the "Dyson Design" (Compl. ¶8).
• Technical Importance: The complaint alleges that this distinctive design has become "iconic" and is associated by the public with the "quality and innovation" of Dyson's products (Compl. ¶¶5, 8).

Key Claims at a Glance

• The patent contains a single claim for "the ornamental design for a hair dryer, as shown and described" ('996 Patent, Claim). The scope of this claim is defined by the visual representations in the patent's seven figures.
• The essential ornamental elements depicted in the figures include:
  • The overall T-shaped configuration of a cylindrical head and a perpendicular cylindrical handle.
  • The specific proportions of the head relative to the handle.
  • An open-ring front nozzle.
  • A rear view showing the back of the cylindrical head.
  • A textured portion at the base of the handle.
• The complaint asserts that Defendants directly and/or indirectly infringe this design (Compl. ¶25).

III. The Accused Instrumentality

Product Identification

• The accused instrumentalities are "unauthorized and unlicensed" hair dryers, referred to collectively as the "Infringing Products," which are allegedly sold by Defendants (Compl. ¶3).

Functionality and Market Context

• The complaint alleges that Defendants make, use, offer for sale, sell, and/or import these hair dryers through numerous interactive e-commerce stores operating under various "Seller Aliases" on platforms such as Amazon, eBay, AliExpress, and others (Compl. ¶¶3, 12). These stores are alleged to target consumers in the United States, including Illinois (Compl. ¶14). The complaint alleges these products are designed to appear as genuine Dyson products to "unknowing consumers" (Compl. ¶15). The complaint provides images from the '996 patent to illustrate the design that the "Infringing Products" are alleged to copy (Compl. p. 4, FIGS. 1-2).

IV. Analysis of Infringement Allegations

The standard for infringement of a design patent is the "ordinary observer" test, which asks 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 does not contain a formal claim chart. Instead, it asserts that the "Infringing Products" infringe the ornamental design claimed in the '996 patent because they are visually substantially the same (Compl. ¶25). This image from the complaint shows a perspective view of the patented design which Plaintiff alleges is infringed (Compl. p. 4, Fig. 2).

• Identified Points of Contention:
  • Factual Question: The central question for infringement will be a factual comparison: does the overall ornamental appearance of the accused hair dryers create substantially the same visual impression as the design claimed in the '996 patent in the eye of an ordinary observer?
  • Procedural Question: As the accused products are alleged to be unauthorized copies sold by concealed entities, a significant issue may not be a nuanced comparison of slightly different designs, but rather establishing that the products sold by each named Defendant are, in fact, the near-identical copies alleged in the complaint.

V. Key Claim Terms for Construction

In design patent litigation, the claim is defined by the drawings, and formal construction of textual terms is rare. The central analysis is a comparison of the accused design to the patented design as depicted in the patent's figures. The scope of the '996 patent's claim is defined by the solid lines in Figures 1-7, and the dispute will likely focus on the visual comparison rather than the interpretation of any specific term.

VI. Other Allegations

• Indirect Infringement: The complaint makes a conclusory allegation of indirect infringement (Compl. ¶25) and requests an injunction against "aiding, abetting, contributing to, or otherwise assisting anyone" in infringing (Compl. p. 11, ¶1(b)). The factual allegations, however, focus primarily on Defendants' own direct acts of making, offering to sell, selling, and importing the accused products.
• Willful Infringement: The complaint alleges that Defendants' infringement was willful (Compl. ¶22). This allegation is supported by claims that Defendants are "working in active concert to knowingly and willfully manufacture, import, distribute, offer for sale, and sell Infringing Products" (Compl. ¶21) and that they employ tactics like using false identities and multiple storefronts to conceal their activities (Compl. ¶¶11, 16-17).

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

• A primary issue will be one of visual comparison: are the hair dryers sold by the Defendants "substantially the same" as the ornamental design claimed in the '996 patent from the perspective of an ordinary observer, such that the observer would be deceived?
• A significant practical challenge will be procedural and evidentiary: given the allegation that Defendants are a diffuse and concealed network of foreign online sellers, can the Plaintiff effectively identify the specific infringing products sold by each Defendant and ultimately enforce any resulting judgment against them?
