Patents & Trademarks
How can I find out if my invention is already patented?
Inventors can perform a preliminary search of patents at the U.S. Patent and Trademark Office Public Patent Search Room, which contains U.S. patents arranged according to the U.S. Patent Classification System of over 460 classes and over 136,000 subclasses. The Patent Search Room is located at 2021 South Clark Place, Room 1A03, Crystal Plaza, Building 3, Arlington, Virginia 22202. It is open to the public from 8:00 am to 8:00 pm, Monday to Friday, except Federal holidays.
Users can access searchable database containing patent information for all U.S. patents granted since 1976 and all patent application publications (first published in March 2001), on the USPTO Web site at http://www.uspto.gov/go/pats.
You may retain a patent attorney or agent to conduct a complete search. For information on registered patent attorneys and agents in your area, you may visit the Office of Enrollment and Discipline Web site at http://www.uspto.gov/go/oed.
Inventors can also perform preliminary search of patents at one of the Patent and Trademark Depository Libraries (PTDLs) established throughout the United States. These libraries have copies of patents in microfilm and/or optical disc format arranged in numerical order. They have classification search tools, automated search aids, and photocopy facilities available to the public. For information on your nearest PTDL, you may visit PTDL Web site at http://www.uspto.gov/go/ptdl.
