Edison's U.S. Patents, 991,433-1,908,830
This list contains the patents Edison received after January 1911. 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.
