Case Timeline

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

U.S. Design Patent No. D853,642

• Patent Identification: U.S. Patent No. D853,642, “Hair styling and hair care apparatus,” issued July 9, 2019. (Compl. ¶8).
• The Invention Explained:
  • Problem Addressed: The complaint does not describe a technical problem but instead focuses on the aesthetic and branding aspects of product design, alleging that Dyson is known for "distinctive patented designs" that are "broadly recognized by consumers." (Compl. ¶8).
  • The Patented Solution: The patent claims the specific ornamental design for a hair styling apparatus. The design, shown in solid lines in the patent's figures, consists of a main cylindrical body, a tapered front end, a specific configuration of circular and ovular control buttons, and a textured band at the rear where the power cord connects. (D'642 Patent, Figs. 1-7; DESCRIPTION, col. 1:53-68). The broken lines in the drawings, such as for the power cord, indicate features that are not part of the claimed design. (D'642 Patent, DESCRIPTION, col. 1:64-68).
  • Technical Importance: The complaint alleges that hair styling products with these designs are associated with the "quality and innovation that the public has come to expect from Dyson Products." (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'642 Patent, CLAIM, col. 1:50-52).
  • The essential visual elements of this claim are defined by the features shown in solid lines in Figures 1-7 of the patent, including:
    • The overall elongated, cylindrical shape of the apparatus body.
    • The specific arrangement of control buttons on the handle.
    • A tapered front portion.
    • A distinct textured grip section near the rear of the apparatus.
  • The complaint asserts infringement of the "Dyson Designs" generally, which includes this patent. (Compl. ¶25).

U.S. Design Patent No. D852,415

• Patent Identification: U.S. Patent No. D852,415, “Hair styling and hair care apparatus,” issued June 25, 2019. (Compl. ¶8).
• The Invention Explained:
  • Problem Addressed: As with the D'642 patent, the focus is on creating a unique ornamental design that consumers associate with the Dyson brand. (Compl. ¶8).
  • The Patented Solution: This patent claims a similar, yet distinct, ornamental design for a hair styling apparatus. Key features shown in the patent's drawings include a cylindrical body, a specific button layout, a perforated end cap, and a textured grip at the rear. (D'415 Patent, Figs. 1-7; DESCRIPTION, col. 1:53-68). Visual comparison of the patent figures suggests minor differences from the D'642 patent, such as the design of the end cap and details of the rear housing.
  • Technical Importance: The complaint groups this patent with the ’642 patent as one of the "Dyson Designs" that are "instantly recognizable" and "symbolize high quality." (Compl. ¶5, ¶8).
• 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'415 Patent, CLAIM, col. 1:50-52).
  • The scope of the claim is defined by the visual features depicted in solid lines in the patent's figures, including the overall shape, button configuration, and surface textures.
  • The complaint asserts infringement of the "Dyson Designs" generally, which includes this patent. (Compl. ¶25).

III. The Accused Instrumentality

Product Identification

The accused instrumentalities are "unauthorized and unlicensed" hair styling and hair care apparatus, collectively referred to as the "Infringing Products." (Compl. ¶3).

Functionality and Market Context

The complaint alleges that the Defendants are e-commerce store operators who make, use, offer for sale, sell, and/or import these products through online marketplace platforms such as Amazon, eBay, AliExpress, TikTok, and Temu. (Compl. ¶3, ¶12). It is alleged that Defendants create storefronts that are designed to appear as if they are "authorized online retailers, outlet stores, or wholesalers" to target unknowing consumers in the United States, including in Illinois. (Compl. ¶14-15). The complaint provides an image from the D'853,642 patent to represent the design of the infringing products. (Compl. p. 4, FIG. 1).

IV. Analysis of Infringement Allegations

The complaint alleges that the Infringing Products "infringe directly and/or indirectly the ornamental designs claimed in the Dyson Designs." (Compl. ¶25). For design patents, infringement is determined by 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 is the patented design. The analysis turns on the similarity of the overall ornamental appearance. The complaint's allegations are summarized below.

D'853,642 Infringement Allegations

D'852,415 Infringement Allegations

• Identified Points of Contention:
  • Visual Similarity: The central question will be whether the overall ornamental appearance of the Defendants' actual products is substantially the same as the designs claimed in the ’642 and ’415 patents from the perspective of an ordinary observer. The court's analysis will involve a side-by-side comparison of the accused products with the patent figures.
  • Evidentiary Challenge: A significant procedural hurdle will be the identification and acquisition of the specific "Infringing Products" sold by the unidentified Defendants for the purposes of comparison, as the complaint itself does not contain photographs of the accused products, relying instead on patent figures and a reference to an unattached "Exhibit 1." (Compl. ¶3).

V. Key Claim Terms for Construction

In design patent litigation, claim construction is typically not a focal point, as the claim is understood to be for the ornamental design as depicted in the patent drawings.

• The Term: The ornamental design for a "hair styling and hair care apparatus."
• Context and Importance: The scope of protection is defined by the visual appearance of the article shown in the drawings. A key aspect of interpreting this scope is distinguishing between the elements claimed (solid lines) and those disclaimed (broken lines). Practitioners may focus on this distinction because it defines the precise boundaries of the intellectual property.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The infringement test considers the "overall ornamental design," suggesting that the impression of the whole is more important than a feature-by-feature comparison. The claim is for the design "as shown and described," incorporating all solid-line features into a single, unitary visual impression. (D'642 Patent, CLAIM, col. 1:50-52).
  • Evidence for a Narrower Interpretation: The patents explicitly state that "The broken lines shown in the drawings illustrate portions of a hair styling and hair care apparatus that form no part of the claimed design." (D'415 Patent, DESCRIPTION, col. 1:64-68). This acts as a clear disclaimer, limiting the scope of the claim to only the elements shown in solid lines and preventing the patentee from claiming infringement based on features shown in broken lines, such as the power cord.

VI. Other Allegations

• Indirect Infringement: The complaint makes a passing allegation of direct "and/or" indirect infringement and requests an injunction against those who "aid" or "abet" infringement. (Compl. ¶25; Prayer for Relief ¶1(b)). However, the body of the complaint does not plead specific facts to support a claim for either induced or contributory infringement, focusing instead on the Defendants' own acts of making, using, and selling the accused products.
• Willful Infringement: Willfulness is explicitly alleged. (Compl. ¶22). The complaint supports this by alleging that Defendants are part of a network of infringers who engage in tactics to evade detection and litigation, such as using fictitious aliases and communicating in online forums about how to continue their operations despite enforcement efforts. (Compl. ¶11, ¶18-19). These allegations suggest that the infringement was knowing and intentional.

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

1. Visual Infringement: The central substantive issue will be one of visual similarity: when viewed by an ordinary observer, is the overall ornamental appearance of the accused products sold by the Defendants substantially the same as the designs claimed in the ’642 and ’415 patents?
2. Procedural Efficacy: A critical procedural question will be the identification of parties and evidence: can the Plaintiff successfully identify the anonymous Defendants and procure exemplars of the specific "Infringing Products" they sold to conduct the necessary infringement comparison and enforce a potential judgment?
3. Damages and Enforcement: Assuming infringement is found, a key challenge will be the quantification and collection of damages. The viability of recovering Defendants' total profits under 35 U.S.C. § 289 will depend on the ability to trace sales and assets of entities that are alleged to operate from foreign jurisdictions with the express purpose of concealing their financial activities. (Compl. ¶20).
