II. Technology and Patent(s)-in-Suit Analysis
U.S. Design Patent No. D799,251 - "Table"
- Issued: October 10, 2017
The Invention Explained
- Problem Addressed: In the field of furniture design, the objective is to create a new, original, and ornamental appearance for an article of manufacture that distinguishes it from prior designs (Compl. ¶8).
- The Patented Solution: The patent protects the specific visual appearance of a table, characterized by the relationship between its primary components. The design creates the visual impression of a large, thick, rectangular tabletop that cantilevers or "floats" over a single, smaller, central pedestal base with inwardly tapered sides (’251 Patent, Fig. 1). The scope of the design is strictly defined by the solid lines in the patent figures; portions shown in broken lines, such as the underside structure, are explicitly disclaimed and form no part of the protected design (’251 Patent, Description). The complaint reproduces figures from the patent to illustrate this design (Compl. p. 3, Figs. 1, 7).
- Technical Importance: The claimed design provides a distinct and modern aesthetic for conference tables, which Plaintiff asserts is a result of its innovation in creating unique furniture designs (Compl. ¶8).
Key Claims at a Glance
- Design patents contain a single claim. The asserted claim is for: "The ornamental design for a table, substantially as shown and described." (’251 Patent, Claim).
- The protected design consists of the visual characteristics embodied in the solid-line drawings, including:
- The overall configuration of a large tabletop supported by a single, recessed central base.
- The specific proportions showing a base that is significantly narrower and shorter than the tabletop.
- The profile of the base featuring inwardly sloping sides.
- The visual effect of a floating or cantilevered top surface.
III. The Accused Instrumentality
Product Identification
Defendant’s "Carina Table" product (Compl. ¶15).
Functionality and Market Context
- The complaint identifies the Carina Table as conference room furniture (Compl. ¶17). Plaintiff alleges Defendant advertises the table on social media and has entered it into an industry design competition, suggesting an effort to position the product in the market for design-focused furniture (Compl. ¶¶16, 17).
- The complaint provides a photograph of the accused Carina Table, which shows a large, rectangular tabletop resting on a single, central base whose sides appear to taper inward (Compl. p. 5). The complaint alleges that the design of this table "copies the ornamental design claimed in the '251 patent" (Compl. ¶15).
IV. Analysis of Infringement Allegations
The infringement test for a design patent is 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 this standard is met (Compl. ¶¶20-21). The central evidence presented is a side-by-side visual comparison of the accused product and a patent figure (Compl. p. 5).
D799,251 Infringement Allegations
| Key Visual Feature of Claimed Design | Alleged Infringing Feature of Carina Table | Complaint Citation | Patent Citation |
|---|---|---|---|
| The overall ornamental appearance of a table as shown in the patent figures. | The complaint alleges the overall design of the Carina Table product copies the ornamental design claimed in the ’251 patent. | ¶15, ¶22 | ’251 Patent, Figs. 1-7 |
| A large, rectangular tabletop appearing to float over a smaller, recessed base. | The accused product is depicted with a large, rectangular tabletop over a central pedestal base that is narrower than the top. | ¶18, p. 5 | ’251 Patent, Fig. 1 |
| A single pedestal base with inwardly tapered side profiles. | The photograph of the accused product shows a base with inwardly sloped sides, creating a similar profile to the patented design. | ¶18, p. 5 | ’251 Patent, Fig. 4, Fig. 5 |
| The overall design being substantially similar in the eye of an ordinary observer. | The complaint alleges an ordinary observer would perceive the overall appearance of the patented design and the Carina Table design to be "substantially the same." | ¶20, ¶27 | ’251 Patent, Claim |
- Identified Points of Contention:
- Scope Questions: The primary dispute will concern the overall visual similarity. A key question is how the "ordinary observer" test applies to the specific designs at issue. The analysis will focus on whether the accused product's design is close enough to the patented design to cause deception. The patent's disclaimer of all elements shown in broken lines will be critical, as it focuses the infringement inquiry strictly on the shapes and contours shown in solid lines (’251 Patent, Description).
- Aesthetic Questions: A potential point of contention may be the effect of different surface materials and ornamentation on the overall visual impression. The accused Carina Table is depicted with a wood-grain top and a marble-patterned base (Compl. p. 5), whereas the patent claims a design via unadorned line drawings. This raises the question of whether these material differences are sufficient to create a distinct aesthetic impression in the eye of an ordinary observer, or if they are merely superficial variations on the same underlying patented design.
V. Key Claim Terms for Construction
In design patent litigation, there are no traditional "terms" to construe. Instead, the court construes the single claim by reference to the patent's figures. The central interpretive issue is the scope of the claimed design as a whole.
- The "Term": "The ornamental design for a table, substantially as shown and described."
- Context and Importance: The entire infringement analysis hinges on the scope of this claimed design. The court's interpretation of what the figures show, and the weight given to the overall configuration versus individual features, will determine the outcome. Practitioners may focus on whether the "substantially as shown" language permits minor variations or requires a near-identical copy.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party may argue that the claim covers the overall visual impression and gestalt of the design—a floating top on a tapered pedestal—and is not limited to the exact proportions or unadorned surfaces in the line drawings. The explicit disclaimer of the internal structure via broken lines supports this, suggesting the claim is focused on the external, ornamental shape (’251 Patent, Description).
- Evidence for a Narrower Interpretation: A party may argue that the claim is limited to the specific visual appearance depicted, including the precise proportions and the stark, unadorned surfaces implied by the line-art style. Under this view, the introduction of prominent patterns, like the marble finish on the accused product's base, could be argued to create a different overall visual impression that falls outside the scope of the claim.
VI. Other Allegations
- Indirect Infringement: The complaint does not allege indirect infringement (inducement or contributory infringement). The claims are for direct infringement based on Defendant’s alleged making, using, and selling of the Carina Table (Compl. ¶27).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of holistic comparison: applying the "ordinary observer" test, will a fact-finder conclude that the accused Carina Table is "substantially the same" as the ornamental design claimed in the '251 patent, or do the differences between the products create distinct overall visual impressions?
- A key evidentiary question will be one of aesthetic distinction: what legal weight will be given to the differences in surface materials and ornamentation (the accused product’s wood and marble finishes versus the unadorned design shown in the patent's line drawings)? The case may turn on whether these are seen as minor variations on the patented design or as creating a new and non-infringing aesthetic.
