4:24-cv-00380
Pleminnyk Trading LLC v. Shenzhen Orange Ant Technology Co
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Pleminnyk Trading LLC (Delaware)
- Defendant: Shenzhen Orange Ant Technology Co. (China)
- Plaintiff’s Counsel: David Fink
- Case Identification: 4:24-cv-00380, S.D. Tex., 02/01/2024
- Venue Allegations: Plaintiff alleges venue is proper because Defendant, a foreign entity, targeted Plaintiff's sales in Houston, Texas, through Amazon.com's patent complaint system, thereby purposefully availing itself of the forum.
- Core Dispute: Plaintiff seeks a declaratory judgment that its egg storage rack products do not infringe Defendant's design patent and that the patent is invalid as being obvious and functional.
- Technical Context: The dispute concerns the ornamental design of a household kitchen product, specifically a spiral-shaped, gravity-fed rack for storing and dispensing eggs.
- Key Procedural History: The action arises from Defendant’s complaints to Amazon.com alleging that Plaintiff’s products infringe the patent-in-suit. These complaints reportedly led Amazon to remove Plaintiff’s product listings, creating a justiciable controversy for which Plaintiff now seeks declaratory relief.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Design Patent No. D902,631 - "Rack for Storage," issued November 24, 2020
The Invention Explained
- Problem Addressed: As a design patent, the '631 patent does not explicitly state a technical problem it aims to solve. The purpose of a design patent is to protect the novel, non-obvious, and ornamental appearance of an article of manufacture (D’631 Patent, Claim).
- The Patented Solution: The patent claims the specific ornamental design for a "Rack for Storage," which is depicted in the patent's figures. The design features a helical wire track supported by vertical struts and a central post, all situated on a tiered circular base (D’631 Patent, Figs. 1-7). The patent's sole claim protects the overall visual impression created by these elements as illustrated, not their mechanical or structural function (D’631 Patent, Claim).
- Technical Importance: The complaint alleges that the design's features are not primarily ornamental but are instead dictated by a utilitarian purpose, specifically to create a gravity-fed dispenser for eggs (Compl. ¶31).
Key Claims at a Glance
- The patent contains a single claim for "The ornamental design for a rack for storage, as shown and described" (D’631 Patent, Claim).
- The scope of a design patent claim is defined by its drawings. The essential elements are the visual characteristics of the rack, including:
- The overall shape and proportion of the helical structure.
- The configuration of the wire track.
- The arrangement of the vertical support struts.
- The appearance of the tiered circular base.
III. The Accused Instrumentality
Product Identification
The complaint identifies the relevant products as "Plaintiff's products" that are used for storing eggs and were sold on Amazon.com (Compl. ¶1, 11).
Functionality and Market Context
The products are described as being functional spiral egg racks, where removing an egg from the bottom causes another to roll down to take its place (Compl. ¶11). The complaint states that both Plaintiff and Defendant sell such products on Amazon.com (Compl. ¶8). The lawsuit was precipitated by Defendant's patent infringement complaints to Amazon, which resulted in Plaintiff's products being removed from the platform (Compl. ¶9, 18).
IV. Analysis of Infringement and Invalidity Allegations
The complaint seeks a declaratory judgment of both non-infringement and invalidity. While it asserts non-infringement, its detailed allegations focus on two specific grounds for why the '631 patent is invalid and therefore cannot be infringed.
Non-Infringement Allegations
The complaint seeks a declaration that Plaintiff is not liable for infringement but does not provide specific factual allegations or visual evidence, such as a side-by-side comparison of its own product with the patented design, to detail its non-infringement theory (Compl. ¶1).
Invalidity Allegation 1: Obviousness (35 U.S.C. § 103)
- The complaint alleges that the design claimed in the '631 patent would have been obvious to a designer of ordinary skill in view of a prior art utility patent, U.S. Patent No. 8,418,859 ("the '859 Patent") (Compl. ¶24, 27). The '859 patent, titled "Spiral Type Cap-Shaped Object Rack," was filed and issued years before the '631 patent was filed (Compl. ¶25). To support this, the complaint provides a side-by-side visual comparison of a figure from the '631 patent and a figure from the prior art '859 patent, arguing they are visually very similar (Compl. p. 6).
- Identified Point of Contention: The central question for this allegation is whether the differences between the prior art '859 patent's design and the '631 patent's claimed design are significant enough to render the '631 design non-obvious to an ordinary designer in the field.
Invalidity Allegation 2: Functionality (35 U.S.C. § 171)
- The complaint further alleges that the '631 patent is invalid because its design is dictated by function rather than being primarily ornamental (Compl. ¶31). Design patent protection does not extend to features of an article that are functional.
- To support this, the complaint cites the specification of the '859 utility patent, which describes the functional advantages of a spiral rack, such as its ability to carry a large number of objects and automatically dispense them in order through gravity (Compl. ¶30, citing '859 Patent, col. 2:26-40). The complaint argues that because the '631 patent depicts a similar design, it is merely an embodiment of these utilitarian principles and is therefore ineligible for design patent protection (Compl. ¶31).
- Identified Point of Contention: This raises the question of whether the overall appearance of the '631 patent design is "primarily functional." The court may need to determine if alternative designs exist that could perform the same egg-dispensing function, which would suggest the specific design of the '631 patent is a matter of ornamental choice rather than functional necessity.
V. Key Claim Terms for Construction
In a design patent case, traditional claim construction of specific text is generally not performed. The "claim" is the design itself, as depicted in the drawings. The central analysis will not be the definition of a word but the comparison of the overall visual appearance of the claimed design against the prior art and the accused product.
- The "Claim": "The ornamental design for a rack for storage, as shown and described" (D'631 Patent, Claim).
- Context and Importance: The dispositive issue is the scope of the design as a whole. The invalidity arguments hinge on comparing the overall visual appearance of the claimed design with the design shown in the '859 patent and assessing whether that appearance is dictated by utilitarian concerns.
- Intrinsic Evidence for Interpretation:
- Evidence for Broader Scope (favoring Patentee): The patentee would argue the claim covers the entire visual impression created by the unique combination of the specific helical pitch, the number and style of the vertical supports, and the precise shape of the base shown in its figures (D’631 Patent, Figs. 1-7).
- Evidence for Narrower Scope (favoring Accused Infringer): The plaintiff argues that the scope is effectively zero because the overall design is functional and/or obvious. The plaintiff cites the '859 patent's disclosure of a nearly identical structure for holding eggs as evidence that the design is functional and lacks ornamentality (Compl. ¶26, 30).
VI. Other Allegations
The complaint does not contain allegations of indirect or willful infringement, as it is a declaratory judgment action filed by the accused infringer.
VII. Analyst’s Conclusion: Key Questions for the Case
This case appears to center on two fundamental questions regarding the validity of a design patent.
A core issue will be one of design obviousness: Would a designer of ordinary skill in the art, viewing the spiral rack design disclosed in the prior art '859 patent, have found it obvious to arrive at the specific ornamental configuration claimed in the '631 patent?
A second dispositive question will be one of functionality: Is the overall visual appearance of the '631 patent's rack design "primarily ornamental," as required for protection, or is it dictated by the utilitarian need to create a gravity-fed dispenser, rendering it ineligible for design patent protection?
