Patent lawyers help clients protect their inventions, by preparing and filing patent applications with the United States Patent Office to obtain the exclusive rights to practice the invention, and further engage in litigation to protect those rights.

Preparation for filing for a patent includes conducting preliminary patent searches to ensure your invention is novel enough to meet Patent Office standards. To obtain a patent, they draft the patent application which includes a technical description of your invention and the claims that define the parameters of your invention and file for a patent and then navigate the patent examination process to obtain the issuance of your patent. They also handle patent disputes, licensing agreements, and infringement cases in the courts.
