¶ 15.47 Characteristic Feature Statement
A "characteristic features" statement describing a particular feature of novelty or nonobviousness in the claimed design may be permissible in the specification. Such a statement should be in terms such as "The characteristic feature of the design resides in [1]," or if combined with one of the Figure descriptions, in terms such as "the characteristic feature of which resides in [2]." While consideration of the claim goes to the total or overall appearance, the use of a "characteristic feature" statement may serve later to limit the claim (McGrady v. Aspenglas Corp., 487 F. Supp. 859, 208 USPQ 242 (S.D.N.Y. 1980)).
Examiner Note:
In brackets 1 and 2, insert brief but accurate description of the feature of novelty or nonobviousness of the claimed design.
