For perspective, the 5 millionth patent was granted in 1991.The United States Patent and Trademark Office (USPTO) issued U.S. patent number 10 million on June 19, 2018. More than just a number, patent 10 million embodies the rich history and strength of the American intellectual property system dating back to the first U.S. patent, signed 228 years ago by George Washington on July 31, 1790, and issued to Samuel Hopkins for a process of making potash, an ingredient used in fertilizer.
The milestone was enshrined during an afternoon ceremony at the White House in which President Donald J. Trump, Secretary of Commerce Wilbur Ross, and USPTO Director Andrei Iancu all signed the patent. The last president to sign a patent was Gerald Ford in 1976 to commemorate the U.S. bicentennial. All early presidents up to John Quincy Adams signed patent documents.
