Definition - Claim

By

Definition: A claim (or claims) is a written statement(s). In a utility patent, claims are the part of the patent application where the inventor specifically states what their invention is and what it can do. Claims define the legal scope of a patent and define what can be protected by patent law. You could say that claims define the invention, what it is and what it does.

The "specification" part of a patent application must end with a claim or claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention or discovery. The claim or claims must conform to the invention as set forth in the remainder of the specification and the terms and phrases used in the claims must find clear support or antecedent basis in the description so that the meaning of the terms in the claims may be ascertainable by reference to the description.

Design Patents - A Single Claim

A design patent application may only include a single claim. The claim defines the design which applicant wishes to patent, in terms of the article in which it is embodied or applied.
