Do I need a patent attorney or agent to file my patent application?
The U.S. Patent and Trademark Office (USPTO) strongly recommends that all prospective applicants retain the services of a registered patent attorney or patent agent to prepare and prosecute their applications. For information on registered patent attorneys and agents in your area, you may visit the USPTO's Office of Enrollment and Discipline Web site at http://www.uspto.gov/web/offices/dcom/gcounsel/oed.htm. Upon request, the USPTO will send informational materials providing a broad overview of the process of obtaining a United States patent. They will include general requirements and a listing of the Patent and Trademark Depository Libraries.
