- Venue Allegations: Venue is asserted based on Defendants allegedly operating interactive e-commerce stores that directly target and sell products to consumers in Illinois, constituting tortious acts within the district.
- Core Dispute: Plaintiff alleges that numerous e-commerce operators are selling water bottle caps that infringe a U.S. design patent for which Plaintiff is the assignee.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Design Patent No. D980,067 - "Water Bottle Cap" (issued March 7, 2023)
The Invention Explained
- Problem Addressed: Design patents protect the ornamental, non-functional appearance of an article of manufacture. The patent does not describe a technical problem but instead presents a new, original, and ornamental design for a water bottle cap.
- The Patented Solution: The patent claims the specific visual appearance of a water bottle cap as depicted in its figures ('067 Patent, Claim, FIGs. 1-8). The design features a generally cylindrical, two-tiered shape. The lower, wider tier has a vertically ribbed or knurled texture, while the upper, narrower tier is smooth. The cap also includes an integrated, offset inner plug element visible in a top-down perspective view ('067 Patent, FIG. 2). The overall aesthetic is defined by the combination and proportion of these elements.
- Technical Importance: The complaint alleges that the patented design is "distinctive" and "broadly recognized by consumers," associating it with the quality of Plaintiff's products (Compl. ¶13).
Key Claims at a Glance
- The patent asserts a single claim: "The ornamental design for a water bottle cap, as shown and described." ('067 Patent, Claim).
- This single claim protects the overall visual appearance of the article shown in the solid lines of the patent drawings.
III. The Accused Instrumentality
Product Identification
The "Infringing Products" are water bottle caps sold by the Defendants through their "Defendant Online Stores" identified in Schedule A of the complaint (Compl. ¶1, ¶15, Schedule A).
Functionality and Market Context
The accused products are alleged to be "unauthorized and unlicensed products which infringe Plaintiff's patented design" (Compl. ¶1). They are sold through commercial online marketplace accounts on platforms such as Amazon, Walmart, and eBay (Compl. ¶22, Schedule A). The complaint alleges that Defendants' online stores are designed to appear as if they are selling genuine or authorized products, using similar marketing strategies and product imagery to deceive consumers (Compl. ¶2, ¶24).
IV. Analysis of Infringement Allegations
Design patent infringement is determined by the "ordinary observer" test, which asks whether an ordinary observer, familiar with the prior art, would be deceived into believing the accused design is the same as the patented design. The complaint alleges that the Infringing Products are a "reproduction, copy or colorable imitation" of the patented design (Compl. ¶35; p. 10, ¶A(a)). A representative figure from the patent, attached as an exhibit to the complaint, shows the claimed design. For example, Compl. Ex. 1, FIG. 1, provides a perspective view of the ornamental design for the water bottle cap. The complaint does not contain images of the accused products for a side-by-side comparison.
’067 Patent Infringement Allegations
| Claim Element (from the single claim) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| The ornamental design for a water bottle cap, as shown and described. | Defendants are making, using, offering for sale, selling, and/or importing into the United States products that feature the ornamental design claimed in the '067 Patent. The complaint alleges these products are colorable imitations of the patented design. | ¶35 | '067 Patent, FIGs. 1-8 |
- Identified Points of Contention:
- Evidentiary Question: The central issue will be evidentiary. Since the complaint does not include images of the accused products, what proof will Plaintiff offer to demonstrate that the products sold by each of the numerous Defendants listed in Schedule A are "substantially the same" as the design claimed in the '067 patent?
- Scope Question: A potential dispute may arise over the scope of the claimed design. The infringement analysis will depend on the degree of similarity required between the accused products and the specific visual features depicted in the patent's figures, such as the proportions of the ribbed and smooth sections and the precise shape of the inner plug.
V. Key Claim Terms for Construction
In design patent litigation, the claim is typically not construed in the same manner as a utility patent. The design as a whole, depicted in the drawings, is what is claimed. The primary focus is on the overall visual impression.
- The Term: "The ornamental design ... as shown and described"
- Context and Importance: The scope of the patent's protection is defined by the solid lines in the drawings. Practitioners may focus on which specific features contribute most to the overall ornamental appearance, and which are disclaimed. The patent's use of broken lines to illustrate unclaimed portions and dot-dash lines to define the claim boundary is critical to this analysis.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party might argue that the claim covers the overall concept of a two-tiered cap with a textured lower band and a smooth upper band, allowing for minor variations in proportion or texture.
- Evidence for a Narrower Interpretation: A party could argue the claim is limited to the exact visual details shown, including the specific number and style of the vertical ribs, the precise ratio between the tiers, and the shape of the inner plug. The patent explicitly uses dot-dash lines in FIG. 8 to "represent the boundaries of the claim," which definitively excludes the bottom-most surface of the cap from the protected design ('067 Patent, Description).
VI. Other Allegations
- Indirect Infringement: The complaint makes a passing allegation of indirect infringement (Compl. ¶31, ¶35) and requests injunctive relief against "aiding, abetting, [or] contributing to" infringement (Compl. p. 10, ¶A(b)). However, it does not plead specific facts, beyond general concert of action, to support the elements of knowledge and intent required for a standalone claim of induced or contributory infringement.
- Willful Infringement: The complaint alleges that Defendants' infringement was willful (Compl. ¶32). This allegation is based on claims that Defendants are an "interrelated group of infringers working in active concert to knowingly and willfully" infringe (Compl. ¶31) and that they communicate via online forums about tactics for evading detection and litigation (Compl. ¶29).
VII. Analyst’s Conclusion: Key Questions for the Case
An Evidentiary Question of Identity: The case's primary hurdle appears to be evidentiary. Can the Plaintiff successfully link each of the dozens of anonymous online seller accounts listed in Schedule A to the sale of products that an ordinary observer would find "substantially the same" as the patented design, especially given the lack of side-by-side visual comparisons in the initial pleading?
A Question of Scope and Similarity: Should the case proceed to the merits, a key question will be the scope of the design patent. How much variation from the precise renderings in the '067 patent figures is permissible before an accused cap is no longer considered a "colorable imitation"? The resolution will depend on comparing the overall visual effect of the accused products with the claimed design.
A Procedural Question of Enforcement: A central practical issue is the effectiveness of the legal strategy itself. The case raises the question of whether a single lawsuit can be an efficient and enforceable mechanism for halting infringement by a large, diffuse, and potentially transient group of foreign-based online sellers.
