10,000,000+ U.S. Patents Issued – Look How Far We've Come


June 19, 2018 – the epic day U.S. Patent No. 10,000,000 was issued. The U.S. government has now issued more than 10 million patents, and it's time we reflect on how far we've come. We all enjoy the countless benefits of patented inventions every day, often without realizing it. As we honor this exciting time in U.S. patent history, we can't help but think about all the passion, grit, and dedication it took inventors and their counselors to get here.   

For those of you not familiar with how patents came to be, here's a brief history lesson: On June 21, 1788, the Constitution of the United States was ratified by the last of the necessary states in order for it to take effect. This Constitution included a provision authorizing Congress "to promote the Progress of Science and useful Arts by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries." Consequently, Congress adopted and President George Washington signed the first U.S. Patent Act, which went into effect on April 10, 1790. This Act empowered any two of the Secretary of State, the Secretary of War, and the Attorney General to grant patents to U.S. citizens for a term of up to 14 years for inventions that were deemed to be "sufficiently useful and important." 

The first U.S. patent was issued on July 31, 1790, to Samuel Hopkins for "An Improvement In The Making Of Potash And Pearl Ash." The patent application filed by Hopkins was reviewed by Thomas Jefferson, Secretary of State, and Henry Knox, Secretary of War, who both signed the patent document along with President George Washington. 

Within the first three years, Secretary Jefferson examined the applications for 55 patents that were granted. However, by 1793, the duties of presidential cabinet members left little time to devote to patent matters. Consequently, the original Patent Act was repealed and replaced by an Act that omitted the requirement that an invention be "sufficiently useful and important," and transferred responsibility for the handling of patent applications to a clerk in the State Department. This eliminated the "examination system" for patent applications and put a "registration system" in place.
