How can I find out the inventor's name of a particular patent?

Users can access searchable databases containing full-text patent information for U.S. patents granted since 1976 and full-page images since 1790 on the U.S. Patent and Trademark Office (USPTO) web site at

A search may also be conducted at a Patent and Trademark Depository Library (PTDL) established throughout the United States. These libraries have copies of patents in multiple formats arranged in numerical order. They also have classification search tools, automated search aids, and photocopy facilities available to the public. For additional information on the nearest PTDL, you may visit our web site at:

The UPTO Public Search Facility staff will conduct an inventor search and provide a list of patent numbers found. This information may be obtained upon request by submitting the inventor's name and approximate date of patent grant and payment of $40 for one hour or fraction thereof, which usually encompasses a 10 year span.

For the current schedule of fees, see the USPTO web site at or you may request that USPTO mail a fee schedule to you. Please note: Fees are subject to change in (usually) October of each year and should therefore be verified before submission to the USPTO. Checks or money orders should be payable to the Commissioner for Patents and sent to:
