What is one unique feature of a Design Patent's claims?

A unique feature of a design patent's claims is that they describe the design as an "ornament" or as applied to an article of manufacture. This terminology emphasizes the aesthetic aspect of the design rather than its functional utility, which is a critical distinction between design patents and utility patents. A design patent protects the ornamental design of an object, and the claims revolve around the visual appearance that is perceived by the eye, making the term "ornament" particularly relevant.

This focus on the ornamental nature highlights the primary goal of a design patent, which is to protect the creative visual qualities of an item rather than how it operates or its utility. In contrast, the other options involve aspects that are either not characteristic of design patents or do not accurately reflect the unique nature of their claims. For instance, describing function pertains more to utility patents, multiple claims can occur in any patent type without being unique to designs, and design patents do not require extensive technical specifications since they center around artistic representation.
