• Case Identification: 1:24-cv-07244, N.D. Ill., 08/14/2024
• Venue Allegations: Venue is alleged to be proper because the defendants target business activities toward consumers in the United States and Illinois through interactive e-commerce stores operating under specified seller aliases.
• Core Dispute: Plaintiff alleges that Defendants’ unauthorized battery packs, sold through various online marketplaces, infringe a U.S. design patent covering the ornamental design of a battery pack.

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

U.S. Design Patent No. D710,299 - "Battery Pack"

• Patent Identification: U.S. Design Patent No. D710,299, "Battery Pack", issued August 5, 2014.

The Invention Explained

• Problem Addressed: Design patents protect ornamentation rather than function. As such, the D710,299 patent does not articulate a technical problem but instead claims protection for a "new, original, and ornamental design for" an article of manufacture, which is a battery pack (D’299 Patent, Title; 35 U.S.C. § 171).
• The Patented Solution: The patent protects the specific visual appearance of a battery pack as depicted in its seven figures (D’299 Patent, CLAIM). The claimed design consists of a main rectangular body with rounded ends, featuring elongated recessed slots on its top surface, and a distinct, upward-projecting connector piece with a complex, multi-faceted geometry. The description clarifies that elements shown in broken lines, such as internal components visible through openings, illustrate "environmental structure and form no part of the claimed design" (D’299 Patent, DESCRIPTION). The complaint includes a perspective view of this design (Compl. p. 4, FIG. 1).
• Technical Importance: The complaint alleges that Dyson products are known for their "distinctive patented designs" that are "broadly recognized by consumers," suggesting the commercial value of the protected aesthetic in the marketplace (Compl. ¶8).

Key Claims at a Glance

• As is typical for a design patent, there is only one claim.
• The single claim covers: "The ornamental design for a battery pack, as shown and described." (D’299 Patent, CLAIM).
• The elements of the claim are the visual characteristics of the battery pack as depicted in solid lines in Figures 1-7 of the patent (D’299 Patent, DESCRIPTION).

III. The Accused Instrumentality

Product Identification

• The accused instrumentalities are "unauthorized and unlicensed" battery packs, referred to as the "Infringing Products" (Compl. ¶3).

Functionality and Market Context

• The complaint alleges that the accused products are sold by numerous e-commerce store operators through online marketplace platforms including Amazon, eBay, AliExpress, and Walmart (Compl. ¶12). These stores are allegedly operated under multiple "Seller Aliases" to conceal the operators' true identities and create the false impression of being authorized retailers (Compl. ¶¶11, 15). The complaint asserts that these sellers target consumers in the United States, including Illinois, and that the products are manufactured by or come from a common source (Compl. ¶¶2, 18).

IV. Analysis of Infringement Allegations

The standard 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 the accused products create a visual impression that is substantially the same as the patented design. The complaint provides a perspective view of the patented design from the patent itself to establish the design at issue (Compl. p. 4, FIG. 1).

D710,299 Infringement Allegations

Claim Element (from the Single Claim)	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, and/or importing into the United States "Infringing Products that infringe directly and/or indirectly the ornamental design claimed in the Dyson Design."	¶25	CLAIM

• Identified Points of Contention:
  • Evidentiary Question: The complaint does not contain images of the accused products, referring only to an unattached "Exhibit 1" (Compl. ¶3). A central question will be what evidence Plaintiff presents to demonstrate that the specific ornamental designs of the various accused products are substantially the same as the claimed design from the perspective of an ordinary observer.
  • Scope Questions: The analysis will depend on a comparison between the accused products and the claimed features shown in solid lines in the patent figures. A potential dispute may arise if the accused products differ in ways that an ordinary observer would notice, or if their resemblance is limited to features corresponding to the unclaimed "environmental structure" shown in broken lines in the ’299 Patent (D’299 Patent, DESCRIPTION).

V. Key Claim Terms for Construction

In design patent cases, claim construction is typically a process of describing the claimed design in words rather than construing specific text-based terms. The controlling "claim" is the visual depiction in the drawings.

• The Term: "The ornamental design... as shown and described"
• Context and Importance: This phrase constitutes the entire claim. Its scope is defined by the solid-line drawings in the patent. The court's verbal description of these drawings will set the boundaries for the infringement analysis. Practitioners may focus on this "construction" process because it will determine which specific visual features are protected and must be compared against the accused products.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: A party might argue for a construction that focuses on the overall visual impression and general configuration of the battery pack—the combination of a rectangular base with a complex vertical connector—as shown across Figures 1-7 (D’299 Patent, Figs. 1-7).
  • Evidence for a Narrower Interpretation: A party could argue for a construction that emphasizes the specific, fine details of the design, such as the exact curvature of the ends, the precise shape and placement of the recessed slots, and the particular angles and facets of the connector piece. The patent’s express disclaimer of the broken-line content as "environmental structure" necessarily narrows the scope of protection to only the features shown in solid lines (D’299 Patent, DESCRIPTION).

VI. Other Allegations

• Indirect Infringement: The complaint alleges that the defendants are "working in active concert" and requests an injunction against "aiding, abetting, contributing to, or otherwise assisting anyone" in making or selling the infringing products (Compl. ¶21; Prayer for Relief ¶1(b)). The factual basis for this appears to be the allegation that the various e-commerce storefronts are interrelated, use common tactics, and sell products from a common source (Compl. ¶¶18-19).
• Willful Infringement: The complaint alleges that the infringement was willful (Compl. ¶22). This allegation is based on the assertion that defendants are part of a network of infringers who knowingly and intentionally use tactics like fictitious aliases and fraudulent registration information to conceal their identities and evade enforcement efforts (Compl. ¶¶11, 16-17, 21).

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

1. The Evidentiary Hurdle: With infringement hinging entirely on a visual comparison and the complaint lacking images of the accused products, a threshold question is: What evidence will Dyson adduce to prove that the products sold by the anonymous defendants under various aliases are, in fact, substantially the same in ornamental design as the D'299 patent in the view of an ordinary observer?
2. The "John Doe" Problem: The case is brought against a schedule of unknown partnerships and associations. A key procedural and substantive challenge will be for the court to determine whether Dyson can successfully establish the identities of the defendants and prove the alleged "logical relationship" and "active concert" among the disparate online seller aliases to hold them jointly responsible for the infringement.
3. Proving Willfulness: Assuming Dyson proves infringement, a central question for damages will be whether it can meet the high bar for willfulness. This will likely depend on uncovering evidence that demonstrates the anonymous defendants had knowledge of the patent or engaged in conduct so egregious as to constitute willful blindness, a difficult task in litigation against unidentified foreign entities.
