For a search of U.S. patents, go to www.uspto.gov/patft/

Unfortunately, when searching for a location for British patents, I could find none on-line. Maybe someone can offer a clue as to their availability.

I have done a lot of research into U.S. patents on different subjects over the years. It used to be that you had to find a Patent Depository Library, and then look up on microfilm. Having them available on-line is terrific.

Happy searching!
