Patent Claim
The portion of a patent that establishes the legal boundaries of the invention -- that is, the exclusive rights of the owner. Patent claims are written in a formal style and precise terminology, and they serve as the basis for any determination of patent infringement. During the application process, patent claims are often the subject of intense negotiation between the applicant and the U.S. Patent and Trademark Office (USPTO).
