The Gilded Age & Industrial Era Unit Exam

A patent gives an inventor the sole legal right to make or sell an invention for a specified period of time. The federal government began issuing patents in 1790. By 1860, only 36,000 had been granted. Between 1860 and 1900, the number skyrocketed to more than 600,000. Edison holds the record for patents issued to one person, with 1,093 in all. ................
