Eleven Million Patents: Milestones in the History of Invention

The United States Patent and Trademark Office (USPTO) issued its 11 millionth patent today, May 11, 2021. America’s first (unnumbered) patent was issued in July of 1790, and patents were numbered consecutively starting in 1836. From there, the pace of patenting accelerated, with 100,000 patents issued by early 1870 and the 1 millionth issued in 1911. Since 2010, the USPTO has issued an average of over 300,000 new patents annually, as inventors and firms around the world have look to the United States as the premier global patent location.
