Dyson Technology Ltd v. Partnerships Unincorp Associations
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Dyson Technology Limited (United Kingdom)
- Defendant: The Partnerships and Unincorporated Associations identified on Schedule “A”
- Plaintiff’s Counsel: Greer, Burns & Crain, Ltd.
- Case Identification: 1:23-cv-04401, N.D. Ill., 07/07/2023
- Venue Allegations: Venue is based on allegations that Defendants operate interactive e-commerce stores that target and make sales to consumers in Illinois.
- Core Dispute: Plaintiff alleges that Defendants’ sale of unauthorized battery packs via online marketplaces infringes a U.S. design patent for a battery pack.
- Technical Context: The dispute is in the consumer electronics accessories market, specifically for battery packs used in products like cordless vacuums, where unique ornamental design serves as a key brand identifier.
- Key Procedural History: The complaint is structured as an action against a group of difficult-to-identify foreign e-commerce operators, alleging they act in concert to sell infringing goods while using aliases and other tactics to conceal their identities and evade enforcement. This is a common litigation model for combating online counterfeit sales.

II. Technology and Patent(s)-in-Suit Analysis
- Patent Identification: U.S. Design Patent No. D710,299, “Battery pack,” issued August 5, 2014 (’299 Patent).
U.S. Design Patent No. D710,299 - “Battery pack”
The Invention Explained
- Problem Addressed: Design patents do not solve technical problems but instead protect the novel, non-functional, ornamental appearance of an article of manufacture. The goal is to protect a product's unique aesthetic, which the complaint alleges has become "iconic" and "instantly recognizable" to the public (Compl. ¶5).
- The Patented Solution: The ’299 Patent claims the specific ornamental design for a battery pack, as depicted in its seven figures (’299 Patent, Claim). The claimed design consists of the visual features shown in solid lines, including a main rectangular body with rounded edges, which supports an upwardly-projecting connector structure. This connector has a distinct profile, with an angled forward face and a series of stepped surfaces and cutouts (’299 Patent, FIG. 1, 4). The patent explicitly states that elements shown in broken lines, which depict environmental structure, are not part of the claimed design (’299 Patent, Description).
- Technical Importance: The complaint asserts that the distinctive designs of Dyson products are a core part of their brand identity and are broadly recognized by consumers as an indicator of quality and innovation (Compl. ¶8).
Key Claims at a Glance
- The single claim asserted is for "the ornamental design for a battery pack, as shown and described" (’299 Patent, Claim; Compl. ¶25).
- The essential visual features comprising this design include:
- The overall configuration and proportions of the battery pack housing and its connector element.
- The specific profile shape of the connector element as viewed from the side.
- The arrangement of surface details, cutouts, and contours on the connector element.
- The top-down and bottom-up appearance of the assembly.
III. The Accused Instrumentality
Product Identification
- The accused products are "unauthorized and unlicensed" battery packs, which the complaint collectively terms the "Infringing Products" (Compl. ¶3).
Functionality and Market Context
- The complaint alleges that Defendants make, use, offer for sale, and sell these battery packs through various e-commerce stores operating under aliases on platforms such as Amazon, eBay, AliExpress, and others (Compl. ¶12). These stores are allegedly designed to appear as authorized retailers to consumers (Compl. ¶15). The complaint includes a perspective view from the ’299 patent to represent the patented design that the accused products allegedly copy (Compl. p. 4, FIG. 1).
IV. Analysis of Infringement Allegations
The standard for design patent infringement is whether, in the eye of an ordinary observer, the two designs are substantially the same, such that the observer would be induced to purchase one supposing it to be the other. The complaint alleges that the accused "Infringing Products" meet this standard.
D710,299 Infringement Allegations
| Claim Element (from Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| The ornamental design for a battery pack, as shown and described. | Defendants are making, using, offering for sale, selling, and/or importing into the United States products that directly and/or indirectly infringe the ornamental design claimed in the '299 Patent. The complaint alleges the accused products feature a design that is the same as or substantially similar to the patented design. | ¶3, ¶25 | Claim; FIG. 1-7 |
- Identified Points of Contention:
- Visual Comparison: The central issue will be a direct visual comparison between the accused products (which are not pictured in the complaint) and the claimed design as depicted in the '299 Patent's figures. The case will depend on whether the overall visual impression of the accused products is substantially the same as the patented design.
- Scope Questions: A potential dispute may arise over which features of the patented design are most significant to its overall appearance. The analysis must properly exclude any consideration of the unclaimed environmental structure shown in broken lines in the patent drawings.
V. Key Claim Terms for Construction
In design patent cases, "claim construction" is a process of defining the scope of the claimed design as a whole, rather than construing individual text-based terms.
- The Term: "The ornamental design for a battery pack, as shown and described."
- Context and Importance: The entire infringement analysis hinges on the scope of this claim. The court's understanding of what visual elements are included in the "design" and the level of similarity required for infringement will be dispositive. Practitioners may focus on ensuring the comparison is made between the accused product and the claimed design as a whole, not by comparing isolated features.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A broader interpretation would focus on the overall visual impression and configuration of the design, arguing that minor differences in detail do not alter the substantial similarity of the whole. The seven figures in the patent, showing the design from multiple viewpoints, collectively define this overall impression (’299 Patent, FIG. 1-7).
- Evidence for a Narrower Interpretation: The patent itself provides a key limitation by explicitly disclaiming certain subject matter. The description states: "The broken lines shown in the drawings are included for the purpose of illustrating environmental structure and form no part of the claimed design" (’299 Patent, Description). This statement definitively narrows the scope of the claim to only the elements depicted in solid lines.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that Defendants have "jointly and severally, knowingly and willfully offered for sale, sold, and/or imported" products that infringe "directly and/or indirectly" the Dyson design (Compl. ¶21). The prayer for relief also seeks to enjoin aiding and abetting (Prayer for Relief ¶1(b)). The factual basis for this is the allegation that Defendants operate as an interrelated group, using common tactics and communication channels (Compl. ¶18, ¶19).
- Willful Infringement: Willfulness is explicitly pleaded (Compl. ¶22). The complaint supports this by alleging that Defendants operate in "active concert" and use "fictitious aliases" and other "common tactics" to conceal their identities and evade enforcement, which may suggest knowledge of the infringing nature of their activities (Compl. ¶17, ¶18, ¶21).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of visual identity: applying the "ordinary observer" test, is the overall ornamental appearance of the accused battery packs substantially the same as the design claimed in the '299 Patent, limited to the features shown in solid lines in the patent's drawings?
- A key evidentiary question will be one of collective liability: can the Plaintiff produce sufficient evidence to demonstrate that the numerous e-commerce storefronts, operating under different aliases, are in fact a single, interrelated enterprise acting in concert, making them jointly and severally liable for the alleged infringement?
