Patent laws have existed for a very long time in some from or another. The Venetian Patent Statute of 1474 is considered the first modern patent law. U.S. patent laws evolved from the Statute of Monopolies in England, from 1624, which had prevented the English Crown from granting “odious” monopolies over entire industries indefinitely. Instead, parliament allowed only “new manufactures” to be patented and only for 14 years. Similarly, the U.S. Constitution authorizes congress to enact patent laws, subject to certain limits, and patents have been available in the United States since 1790.

What modern patent laws have in common is the concept of a quid pro quo. In exchange for disclosing how to make and use an invention, a government will grant the inventor an exclusive right in that invention for a limited time. The idea is that this promotes progress in engineering and science—the “useful arts”. A patent is an incentive for inventors to disclose their inventions rather than keep them secret. And when the limited term of a patent expires, the public is then able to freely use the invention. These are the policies behind patent laws.
