The first patent

The first patent in history was issued in 1421 by the city government of Florence in the name of Filippo Brunelleschi (1377-1446). The famous architect, sculptor, scientist, one of the creators of the Renaissance architecture and the theory of linear perspective, invented... a ship's rotary crane. Extremely concerned about the slowness of loading marble slabs for his workshop, he invented and installed a wooden structure on the barge, with which help it was possible to speed up the rigging. And since the mechanism turned out to be extremely successful, Brunelleschi decided to protect his authorship officially - he issued the first patent in the city government of the city. And, as it turned out, he acted very sensibly: soon the German trade union Hansa bought from him the first license to use this invention.

The first patent of England was issued on April 3, 1449 to the Flemish master John Utnam for the production of stained glass windows for 20 years. The first patent signed by President George Washington in the United States was issued on July 31, 1790 to Samuel Hopkins, Philadelphia, Pennsylvania.

Recall that the patent (from the Latin patens - open, clear) - a security document certifying the exclusive right, authorship and priority of the invention, utility model or industrial design. Its validity period depends on the country of patenting, the object of patenting and is from 5 to 25 years.

The legal protection that the patent provides protects the solution, not the task. For example, James Watt, in order to solve the problem of transforming the reciprocating motion into a rotary one and bypassing the patent for a crank mechanism, applied a planetary gear instead of a crank.
