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

U.S. Patent No. D650,534 - “Poultry Nesting Box,” issued December 13, 2011.

The Invention Explained

  • Problem Addressed: As a design patent, the ’534 Patent does not address a functional problem but instead seeks to protect a new, original, and ornamental design for an article of manufacture (Compl. ¶10; ’534 Patent, CLAIM).
  • The Patented Solution: The patent protects the specific visual appearance of a poultry nesting box. The claimed design features a generally rectangular housing with a sloped top surface, an arched front opening for poultry entry, a small perch extending from the bottom of the opening, and two parallel, horizontal, rib-like indentations on the side walls (’534 Patent, Figs. 1-4). The overall impression is of a clean, modern, and distinctively shaped container for its purpose.
  • Technical Importance: The design's importance lies in its aesthetic distinctiveness within the farm and ranch supply market, which Plaintiff alleges has become associated with its "LITTLE GIANT®" trademark and serves as a source identifier (Compl. ¶12).

Key Claims at a Glance

  • Design patents contain a single claim. The asserted claim is: "The ornamental design for a poultry nesting box, as shown and described" (’534 Patent, CLAIM).
  • The scope of this claim is defined by the six figures included in the patent, which depict the design from perspective, front, right, left, top, and bottom views (’534 Patent, DESCRIPTION).

III. The Accused Instrumentality

Product Identification

  • The "Accused Products" are chicken nesting boxes marketed and sold by Defendant under the "Wolltex" brand, including the "6 Pack of Large Chicken Nesting Boxes with 6 Nesting Pads and Screws" (Compl. ¶1, ¶18, Ex. 4).

Functionality and Market Context

  • The accused products are plastic nesting boxes for chickens, offered for sale on the Amazon.com marketplace (Compl. ¶14, ¶18). The complaint includes a screenshot of the Amazon product listing, showing a price of $159.99 for a six-pack and identifying "wolltex" as the brand (Compl. ¶18, Ex. 4). A shipping label from a purchased unit also identifies "WOLLTEX" as the shipper (Compl. ¶19, Ex. 5). The complaint alleges that Defendant sources these products from various manufacturers in China for sale to U.S. consumers (Compl. ¶22).

IV. Analysis of Infringement Allegations

The complaint does not contain a traditional textual claim chart. Instead, it bases its infringement allegation on a direct, side-by-side visual comparison of the patented design, the Plaintiff's commercial product, and the accused Wolltex product (Compl. ¶20, Ex. 6). The legal test for design patent infringement is whether an "ordinary observer," taking into account the prior art, would believe the accused design to be the same as the patented design.

The complaint alleges that "[a]ll design features of the Accused Product are substantially identical to the design of the Asserted Patent" (Compl. ¶20). This allegation is supported by a detailed photographic table presented as Exhibit 6. For example, the "Front Perspective View" comparison shows the Wolltex product next to the patent drawing, both depicting a similarly sloped top, an arched opening, a front perch, and side indentations (Compl. p. 7, Ex. 6). The complaint uses this and other views (e.g., "Front Elevation," "Right Side Elevation") to argue that the overall visual impression of the accused product is the same as the patented design (Compl. p. 7-8, Ex. 6).

  • Identified Points of Contention:
    • Scope Questions: The primary question in a design patent case is the scope of the visual impression. The dispute will center on whether the overall appearance of the accused Wolltex product is "substantially the same" as the design claimed in the ’534 Patent.
    • Technical Questions: The key factual question for the court will be whether any minor differences between the accused product and the patent drawings are sufficient to create a different overall visual impression for an ordinary observer. The defense may argue that subtle variations in curvature, proportions, or the specific shape of features like the perch or side ribs distinguish its product from the patented design.

V. Key Claim Terms for Construction

In design patent litigation, claim construction is typically not a central issue, as the claim's scope is defined by the drawings rather than by textual limitations. The single claim recites "the ornamental design for a poultry nesting box, as shown and described" (’534 Patent, CLAIM). The analysis focuses on the overall visual appearance conveyed by the patent figures. The dispute is not likely to involve the definition of any particular word but rather the holistic visual scope of the design itself. The court's analysis will likely proceed directly to comparing the accused product to the claimed design under the "ordinary observer" test.

VI. Other Allegations

  • Indirect Infringement: The complaint specifically alleges that Defendant induces infringement by causing foreign manufacturers to make and ship the accused products into the United States for sale on Amazon.com (Compl. ¶22, ¶26). To support this, the complaint names six distinct Chinese manufacturing companies, complete with addresses, that allegedly produce and offer for sale products "substantially identical" to the accused products (Compl. ¶22, ¶24).
  • Willful Infringement: Willfulness is alleged on the basis that Defendant's infringement "has been, and continues to be knowing, intentional, willful, wanton, and deliberate" (Compl. ¶27). The complaint supports this by presenting side-by-side visual evidence suggesting that the similarity between the products is not coincidental (Compl. ¶20, Ex. 6).

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

  • A central issue will be one of "visual identity": under the "ordinary observer" test, is the overall ornamental design of the accused Wolltex nesting box "substantially the same" as the design claimed in the ’534 Patent, or are there sufficient visual differences to distinguish them in the eyes of a consumer?
  • A key procedural question will be one of "personal liability": will the plaintiff's allegations that Wolltex, LLC is a "sham corporate shield" be sufficient to pierce the corporate veil and hold the individual defendant, Alejandro Canales, personally liable for the alleged infringement?
  • A critical evidentiary question will be the "proof of inducement": can the plaintiff demonstrate that the defendant took affirmative steps to encourage the named Chinese manufacturers to supply infringing products for importation into and sale within the United States, as required to establish a claim for induced infringement?
