A countdown to the 10 millionth Patent

Next Tuesday 19th June, the United States Patent and Trademark Office (USPTO) will issue their 10 millionth patent. In celebration, here are some key points in the USPTO’s history!

The first Patent Board was composed of Secretary of State Thomas Jefferson, Secretary of War Henry Knox, and Attorney General Edmund Randolph following the 1790 Patent Act. Patent Number 1, signed by President George Washington, was awarded to Samuel Hopkins for the improvements in making ‘pot ash and pearl ash’, otherwise known as a form of fertilizer. In 1802, Dr William Thornton became the first ‘Superintendent of Patents’ and served for 26 years. In 1975, the Patent Office was renamed to become the United States Patent and Trademark Office (USPTO) as we know it today and in 2003, the headquarters were moved from Washington D.C. to Alexandria, Virginia.

In the lead up to the 10 millionth patent there is great excitement as to who will be named the patent holder. Let’s look at the past millionth patent holders and their inventions:

1911: Francis H. Holton received US patent no. 1,000,000 for an improvement in vehicle tires.

1935: Joseph Ledwinka received US patent no. 2,000,000 for a pneumatic tire for rail cars.

1961: Kenneth Eldredge received US patent no. 3,000,000 for an automatic reading system that converts human language into machine language.
