Question: How important are the claims in a patent application?
Answer: Claims define the invention and are what are legally enforceable. They are extremely important.
Whether a patent will be granted is determined, in large measure, by the wording of the claims. Claims continue to be important once a patent is granted, because questions of patent validity and patent infringement are judged by the courts on the basis of the claims.
The fee required to be submitted with a non-provisional utility patent application is, in part, determined by the number of claims and type of claims.
