The First U.S patent

Samuel Hopkins petitioned for a patent on an improvement “in the making of Pot ash and Pearl ash by a new apparatus and process. The U.S. patent statute did not create a Patent Office. A committee of the Secretary of State, Secretary of War and the Attorney General were authorized to make a decision on the merit of a properly documented petition.
The first patent was signed by George Washington, Edmund Randolph, and Thomas Jefferson. The first Canadian patent was also granted to Samuel Hopkins, Angus MacDonnel and a Scottish soldier in 1791.
