Edison's U.S. Patents, 90,646-242,901

This list contains the patents Edison received before June 1881. It is arranged in chronological order by issue date, the time at which the patent, having passed inspection and any legal challenges, was awarded. The execution date is the date on which Edison signed the application and the date in the patenting process that comes closest to the time of actual inventive activity; the application date is the date on which the Patent Office received and recorded the application. The number in the first column indicates the order of the patents' execution.
