U.S. patent law Edit

An experimental use of an invention is the applicant's use of the invention for testing or experimental purposes (rather than for public or commercial purposes). Such use is not considered when computing the one-year period. The experimentation must be to verify that the invention works for its intended purpose as distinguished from other factors such as marketing research.[1]
