- Core Dispute: Plaintiff alleges that Defendant’s "Copper Pro Square Pan" infringes a design patent that protects the ornamental appearance of Plaintiff's "COPPER CHEF" pan.
- Technical Context: This dispute concerns the ornamental design features of consumer cookware, specifically in the competitive market for square, non-stick frying pans.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Design Patent No. D772,641 - "PAN"
- Patent Identification: U.S. Design Patent No. D772,641, titled "PAN," issued November 29, 2016.
The Invention Explained
- Problem Addressed: As a design patent, the ’641 Patent does not purport to solve a technical or functional problem. Instead, it protects the novel, non-functional, ornamental appearance of the article of manufacture, in this case, a cooking pan (D772641 Patent, Claim).
- The Patented Solution: The patent claims the specific visual appearance of a pan as depicted in its figures. The claimed design consists of a deep, square-shaped pan body with rounded corners and a flat bottom featuring a circular induction plate. The design also includes a long, slightly curved primary handle attached to one side and a smaller, C-shaped helper handle on the opposite side (D772,641 Patent, Figs. 1, 6, 7).
- Technical Importance: The complaint alleges that the pan design protected by the patent is embodied in Plaintiff's "highly successful 'COPPER CHEF' square pan," which has "attained immense success in the marketplace," suggesting the design's commercial significance (Compl. ¶2).
Key Claims at a Glance
- The patent asserts a single claim: "The ornamental design for a pan, as shown and described." (D772,641 Patent, Claim).
III. The Accused Instrumentality
Product Identification
- The "Copper Pro Square Pan," also referred to as the "Copper Pro" (Compl. ¶4).
Functionality and Market Context
- The complaint identifies the Accused Product as a cooking pan sold by Defendant, a direct competitor to Plaintiff (Compl. ¶4). The central allegation is not about the pan's function but its appearance, which is described as a "direct knockoff" of the Plaintiff's product embodying the patented design (Compl. ¶4).
- The complaint provides a side-by-side visual comparison to support its allegation that the Accused Product has appropriated Tristar's protected design (Compl. ¶6). The complaint provides a three-panel image comparing the Plaintiff's product, the Defendant's product, and a figure from the patent, all showing a square, copper-colored pan with similar handle configurations (Compl. ¶6).
IV. Analysis of Infringement Allegations
Design patent infringement is assessed from the perspective of an "ordinary observer." Infringement is found if, in the eye of such an observer, the two designs are substantially the same, such that the observer would be induced to purchase one product supposing it to be the other. The complaint alleges infringement by presenting the Accused Product as visually indistinguishable from the patented design.
D772,641 Patent Infringement Allegations
| Claim Element (Visual Feature from the Claimed Design) | Alleged Infringing Functionality (Visual Feature of the Accused Product) | Complaint Citation | Patent Citation |
|---|---|---|---|
| The overall ornamental design for a pan, as shown and described. | The "Copper Pro" product is alleged to be a "direct knockoff" that infringes the ’641 Patent. | ¶4 | Claim |
| Overall square shape with rounded corners and deep sides. | The "Copper Pro" pan is depicted with a visually similar square body, rounded corners, and side wall height. | ¶6 | Figs. 1, 6 |
| An elongated, slightly curved primary handle. | The "Copper Pro" pan is depicted with a long primary handle of a similar shape and curvature. | ¶6 | Figs. 1, 4 |
| A smaller, C-shaped helper handle opposite the primary handle. | The "Copper Pro" pan is depicted with a C-shaped helper handle in the same position and of a similar shape. | ¶6 | Figs. 1, 2 |
- Identified Points of Contention:
- Overall Visual Impression: The primary question for the court is whether an ordinary observer, viewing the Accused Product and the patented design, would find their overall visual appearances to be substantially the same. The complaint's side-by-side comparison directly frames this as the central issue (Compl. ¶6).
- Effect of Minor Differences: A potential point of contention may be whether any minor, subtle differences in proportions, handle curvature, or material finish between the Accused Product and the patent figures are sufficient to alter the overall visual impression in the eye of an ordinary observer, or if those differences are trivial.
- Role of Prior Art: Though not addressed in the complaint, a key issue in design patent litigation is the context provided by prior art. The scope of the patent and the level of similarity required for infringement will be informed by whether the claimed design is a significant departure from prior art pans or a modest variation in a crowded field.
V. Key Claim Terms for Construction
In design patent cases, claim construction focuses less on textual definitions and more on the visual scope of the design as depicted in the drawings.
- The Term: The scope of the claimed design as defined by solid vs. broken lines in the patent figures.
- Context and Importance: Practitioners may focus on this distinction because it is the primary tool for defining the boundaries of a design patent claim. Features shown in solid lines are part of the claimed design, while features shown in broken lines are for illustrative or environmental purposes only and are explicitly disclaimed. This distinction is critical for determining what features are protected and can form the basis of an infringement claim.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The infringement test considers the "design as a whole," which could support an argument that the overall visual impression, rather than a checklist of individual features, should be the focus.
- Evidence for a Narrower Interpretation: The patent specification explicitly states: "The elements depicted in broken lines in the various figures are included for environmental purposes only, and form no part of the claimed design" (D772,641 Patent, Description). This language limits the claim scope strictly to the features of the pan itself (shown in solid lines) and disclaims, for example, the stove burner shown in broken lines in Figure 8.
VI. Other Allegations
- Indirect Infringement: The complaint alleges active inducement of infringement under 35 U.S.C. § 271(b), stating on information and belief that Novel Brands knowingly aided and abetted others to make, use, or sell infringing products (Compl. ¶¶14-15). The complaint does not plead specific facts detailing the alleged acts of inducement.
- Willful Infringement: The complaint seeks enhanced damages based on alleged "willful, wanton, and deliberate acts of infringement" (Compl. p. 4, ¶(d)). The factual basis for this allegation appears to be the assertion that the Accused Product is a "direct knockoff" of Plaintiff's product, which may suggest intentional copying (Compl. ¶4).
VII. Analyst’s Conclusion: Key Questions for the Case
- A Core Factual Question: The central issue for determination is a factual one: Applying the "ordinary observer" test, is the overall ornamental design of the accused "Copper Pro" pan substantially the same as the design claimed in the ’641 Patent? The resolution will depend on a comparison of the designs as a whole, as presented through evidence at trial.
- The Role of Prior Art: A key question that will shape the infringement analysis is the context of the prior art. The court will need to determine whether the relevant field of cookware design is crowded with similar square pans, which would narrow the scope of the patent’s protection to its precise details, or if the patented design is sufficiently distinct from prior art to be afforded a broader scope of protection.
- The Question of Willfulness: Should infringement be found, a critical question for damages will be whether Defendant's actions were willful. This inquiry will likely focus on evidence of whether Defendant copied the patented design, its knowledge of the ’641 Patent, and whether it had a good faith belief that its product was non-infringing.
