X-Patent
On July 31, 1790 inventor Samuel Hopkins of Pittsford, Vermont became the first person to be issued a patent in the United States. His patented invention was an improvement in the "making of Pot Ash by a new apparatus & process." The earliest patent law required that a working model of each invention be produced in miniature.
History of Connecticut industry
The "'history of Connecticut Industry" is a major part of the history of Connecticut. Between the birth of the U.S. patent system in 1790 and 1930, Connecticut had more patents issued per capita than any other state; in the 19th century, when the U.S. as a whole was issued one patent per three thousand population, Connecticut inventors were issued one patent for every 700–1000 residents. Connecticut's first recorded invention was a lapidary machine, by Abel Buell of Killingworth, in 1765.
