Steamboat patentIn 1809, Robert Fulton patented his steamboat for the first time in the U.S., although he had already made his first successful steamboat trip on the Clermont between New York City and Albany in 1807. He obtained a supplementary patent on 9 Feb 1811. Few inventions have been as important as the steamboat, which opened up American rivers to two-way travel. Obtaining the patent for which he applied on 1 Jan 1809 was routine. However, defending them against the lawsuits of competitors proved troublesome for years. He also had to be wary of the Superintendent of Patents, Dr. William Thornton, who had a conflict of interest from his association with John Fitch's Delaware steamboat. |
