2:20-cv-09255
Playology LLC v. CB Worldwide Inc
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Playology, LLC (Delaware)
- Defendant: C.B. Worldwide, Inc., dba Mammoth Pet Products (California)
- Plaintiff’s Counsel: Stris & Maher LLP
- Case Identification: 2:20-cv-09255, C.D. Cal., 10/08/2020
- Venue Allegations: Plaintiff alleges venue is proper in the Central District of California because a substantial part of the events giving rise to the claim occurred there, including correspondence from Defendant’s counsel located in the district, and because Defendant is subject to personal jurisdiction in the district.
- Core Dispute: Plaintiff Playology, the accused infringer, seeks a declaratory judgment that it does not infringe three of Defendant Mammoth's design patents for rope-based pet toys and that the patents are invalid.
- Technical Context: The dispute concerns the ornamental designs of braided rope dog toys, a segment of the pet products market where visual appearance can be a significant factor in consumer choice.
- Key Procedural History: The complaint was filed after a series of communications between the parties. Defendant sent a cease-and-desist letter to Plaintiff in October 2019, followed by another to one of Plaintiff’s customers in December 2019. These letters, which alleged infringement and threatened legal action, created the "immediate, real, and justiciable controversy" that forms the legal basis for this declaratory judgment action.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Design Patent No. D743,638 - "Double Knotted Braided Rope Pet Toy"
The Invention Explained
- Problem Addressed: Design patents do not contain a "problem/solution" narrative like utility patents. The filing of the application itself suggests a perceived need for a new and original ornamental design for a pet toy.
- The Patented Solution: The patent claims the specific ornamental appearance of a pet toy made from braided rope (Compl. ¶ 20). The design consists of a central braided rope shaft with a large, spherical knot at each end, terminating in frayed rope ends (’638 Patent, FIG. 1). The visual character is defined by the overall bone-like shape, the texture of the braided rope, and the configuration of the knots.
- Technical Importance: The patent seeks to protect a specific aesthetic for a common article, suggesting that the particular combination of knot style, rope texture, and overall shape was considered a novel visual presentation in the pet toy market at the time of filing ('638 Patent, Claim).
Key Claims at a Glance
- The patent contains a single claim for "The ornamental design for a double knotted braided rope pet toy, as shown and described" (Compl. ¶ 20).
- As a design patent, the claim's scope is defined by the drawings. The essential visual elements are:
- A braided rope structure.
- A generally linear central portion.
- Two terminal, substantially spherical knots.
- Frayed ends extending from the knots.
U.S. Design Patent No. D744,175 - "Triple Knotted Braided Rope Pet Toy"
The Invention Explained
- Problem Addressed: Similar to the '638 Patent, this design patent addresses the need for a new ornamental design in the pet toy field.
- The Patented Solution: The patent claims the ornamental design for a braided rope toy characterized by three spherical knots spaced along a central rope shaft (’175 Patent, FIG. 1). The design features a knot at each end and one in the middle, with all knots appearing substantially similar in size and construction, and the toy terminating in frayed rope ends (Compl. ¶ 27).
- Technical Importance: This patent protects a variation on the braided rope toy theme, distinguishing itself from other designs through the specific number and arrangement of its knots, which creates a distinct visual impression ('175 Patent, Claim).
Key Claims at a Glance
- The patent contains a single claim for "The ornamental design for a triple knotted braided rope pet toy, as shown and described" (Compl. ¶ 27).
- The essential visual elements defined by the drawings are:
- A braided rope structure.
- Two terminal knots and one central knot.
- Substantially uniform spacing between the knots.
- Frayed ends extending from the terminal knots.
U.S. Design Patent No. D778,002 - "Rope Ball Pet Toy with Pull"
The Invention Explained
- Technology Synopsis: The patent claims the ornamental design for a pet toy consisting of a single, large spherical knot, often referred to as a "monkey's fist" knot, with a braided rope loop extending from it to serve as a handle (’002 Patent, FIG. 1). The design's appearance is defined by the combination of the complex, woven ball and the simple, attached loop handle.
- Accused Features: Plaintiff's "Dri-Tech Rope and Dri-Tech Knot" toys are accused of infringing the '002 Patent (Compl. ¶¶ 18, 19).
Key Claims at a Glance
- Asserted Claims: The patent asserts a single claim for "The ornamental design for a rope ball pet toy with pull, as shown and described" (Compl. ¶ 34).
III. The Accused Instrumentality
Product Identification
Plaintiff's "Dri-Tech Rope and Dri-Tech Knot dog toys" (Compl. ¶ 4).
Functionality and Market Context
The complaint alleges that Plaintiff's products are rope-based dog toys (Compl. ¶ 5). The primary technical distinction raised by the Plaintiff is that its products utilize a "basket" weave pattern (Compl. ¶ 15). Plaintiff contrasts this with what it characterizes as a "chevron" weave in the patented designs, alleging this difference is substantial (Compl. ¶ 15). The complaint does not provide further details on the market context of the accused products but notes that Defendant sent a cease-and-desist letter to one of Plaintiff's customers, suggesting the products are in commercial distribution (Compl. ¶ 13).
IV. Analysis of Infringement Allegations
As this is a declaratory judgment action, the "allegations" are Plaintiff's assertions of non-infringement. The analysis is based on the infringement standard for design patents, which asks whether an "ordinary observer," familiar with the prior art, would be deceived into purchasing the accused product believing it to be the patented design.
The complaint includes a perspective view of the patented design from the '638 patent, which shows a braided rope toy with two knots and frayed ends (Compl. ¶ 21, FIG. 1).
'638 Patent Infringement Allegations
| Claim Element (from the single design claim) | Alleged Non-Infringing Feature | Complaint Citation | Patent Citation |
|---|---|---|---|
| The ornamental design for a double knotted braided rope pet toy, as shown and described. | Plaintiff alleges its accused products do not infringe because they use a "basket" weave pattern, which creates a different overall visual impression from the design shown in the patent's figures. | ¶22, ¶26 | '638 Patent, FIGS. 1-7 |
The complaint provides a perspective view of the '175 patent's design, illustrating a rope toy with three knots and frayed ends (Compl. ¶ 28, FIG. 1).
'175 Patent Infringement Allegations
| Claim Element (from the single design claim) | Alleged Non-Infringing Feature | Complaint Citation | Patent Citation |
|---|---|---|---|
| The ornamental design for a triple knotted braided rope pet toy, as shown and described. | Plaintiff alleges its accused products do not infringe because their "basket" weave pattern distinguishes them visually from the patented design. | ¶29 | '175 Patent, FIGS. 1-7 |
- Identified Points of Contention:
- Scope Questions: The central question for infringement is whether the claimed "ornamental design" is limited to the specific "chevron" style of braid depicted in the patent figures, or if it is broad enough to cover other braiding styles, like the alleged "basket" weave, when used in the same general configuration of knots and rope.
- Technical Questions: A factual dispute will likely arise over the visual significance of the different weave patterns. The court will need to determine whether an ordinary observer would perceive the difference between the "chevron" weave in the patent figures and the alleged "basket" weave of the accused products, and whether that difference is substantial enough to avoid confusion as to the source of the product.
V. Key Claim Terms for Construction
In design patent cases, analysis focuses less on textual definition and more on the visual scope of the claim as illustrated in the drawings. The key visual feature in dispute is the rope braid itself.
- The Term: The "Braided Rope" texture/pattern as shown in the patent figures.
- Context and Importance: Plaintiff’s non-infringement argument is founded entirely on the assertion that its products use a different "basket" weave, as opposed to the "chevron" weave it attributes to the patented designs (Compl. ¶ 15). Therefore, the visual scope of the claimed braid pattern will be dispositive for the infringement analysis.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party could argue that the claim covers the overall visual impression, where the general shape (e.g., two knots on a rope) is the dominant feature and the specific micro-texture of the braid is a minor detail an ordinary observer might overlook. The patent claims the "ornamental design... as shown," which encompasses the entire configuration ('638 Patent, Claim).
- Evidence for a Narrower Interpretation: The patent drawings for the '638 and '175 Patents consistently and clearly depict a specific, repeating V-shaped or "chevron" pattern across all surfaces of the rope and knots ('638 Patent, FIGS. 1-7). A party could argue that this highly detailed and consistently rendered pattern is an integral part of the claimed design, and that any other pattern, such as a "basket" weave, would create a different overall visual impression.
VI. Other Allegations
- Invalidity: Plaintiff seeks a declaration that all three Patents-in-Suit are invalid under 35 U.S.C. §§ 102, 103, and/or 171 (Compl. ¶¶ 42, 46, 50). The complaint alleges invalidity based on two primary grounds:
- Anticipation/Obviousness: The design is allegedly anticipated or rendered obvious by prior art, including references provided by Plaintiff to Defendant during pre-suit correspondence (Compl. ¶¶ 42, 46, 50).
- Functionality: Plaintiff alleges the claimed designs are "purely functional" (Compl. ¶¶ 42, 46, 50). A design dictated solely by function, rather than ornamental considerations, is not eligible for design patent protection. This raises the question of whether the shape, knots, and braid are driven by utilitarian concerns (e.g., durability, grip for a dog) rather than aesthetics.
- Indirect Infringement: Plaintiff seeks a declaratory judgment that it does not induce or contribute to the infringement of any of the patents by its customers (Compl., Prayer for Relief ¶¶ A, C, E).
- Willful Infringement: As a declaratory judgment plaintiff, Playology makes no allegation of willfulness. However, the complaint confirms that Defendant provided Plaintiff with actual notice of the patents and its infringement allegations on October 31, 2019 (Compl. ¶ 11). These facts could form the basis for a future counterclaim of willful infringement by Defendant.
VII. Analyst’s Conclusion: Key Questions for the Case
This declaratory judgment action appears to center on fundamental questions of design patent scope and validity. The resolution of the case will likely depend on the court's findings on the following key issues:
Infringement—The "Ordinary Observer" Test: The dispositive infringement question will be a factual one of visual perception: does the alleged "basket" weave of the Plaintiff's products create an overall ornamental appearance that is "plainly dissimilar" to the designs shown in the patents, or would an ordinary observer be deceived into believing the products are the same?
Validity—The Functionality Doctrine: A core validity issue will be whether the patented designs are "purely functional." The court will have to determine if the designs—including the number and placement of knots and the choice of a braided rope—are dictated by utilitarian purposes (e.g., making the toy durable or easy for a dog to chew) or if they possess a non-functional, ornamental character protected by law.
Validity—Obviousness over Prior Art: An evidentiary question will be whether the patented designs would have been obvious to a designer of ordinary skill in the art of pet toys at the time of invention. This will depend on the specific prior art designs that Plaintiff can produce, which are referenced but not detailed in the complaint.
