The concept of patenting reaches back to ancient times, though there is some dispute over which innovator succeeded as the first intellectual-property pioneer. As early as 600 B.C., according to British intellectual property expert Robin Jacob, a patent was documented for “some kind of newfangled loaf” of bread.

Here’s a look at some historical milestones in the long history of patents:


Some historians date the first industrial patent filing back to 1421, attributing it to Filippo Brunelleschi, a Florence architect who developed a crane system for shipping and transporting marble from the Carrara mountains.

John of Utynam, a Flemish glassmaker, is considered the first person on record to have been awarded an English patent in 1449. Granted by King Henry VI, the exclusive rights gave John a 20-year monopoly on producing stained glass — a technique that was until that point unknown in England.


By 1474, the Venetian Senate set up the first patent law articulating the concept of intellectual property and enshrining the importance of protecting inventors’ rights. The Venetian Act is cited as the foundation for modern international patent statutes and was a “huge breakthrough in Renaissance Venice,” said Craig Nard, director of the Intellectual Property Center at Ohio’s Case Western Reserve University.

“Everything we hold dear as sort of fundamental principles in today’s patent system can be found in that Venetian statute,” he said.


During the reign of Queen Elizabeth I and her successor, King James I, the royal court bestowed patents on well-established techniques or commodities (vinegar and playing cards, for instance) to favored courtiers, Nard said. This patronage raised some civil unrest, and administration of patents was transferred to common law courts.

“In 1624, parliament had enough of this abuse of practice,” he said. “So they enacted this Statute of Monopolies in Section 6 that said we’re OK with patents, but you have to grant them on inventions that are actually novel.”

The rollback of the Crown’s powers governed English patent law for more than two centuries and forms the foundation of the modern British patent system, as well as a model for U.S. Patent Law.


The 1787 U.S. Constitution laid the groundwork for granting patent rights to inventors in Article One, section 8, clause 8.

“Our founders actually contemplated intellectual property, patents and copyrights, which I think was remarkable,” Nard said.

A year after the constitution was ratified came America’s first Patent Act, on April 10, 1790.

More major reform came with the Patent Act of 1952, which further strengthened the patent system by introducing “non-obviousness” of procedure or product as a requirement for obtaining a patent.

“The 1952 act provided a greater menu of vehicles to show infringement,” said Nard, who described the revised act as the “backbone” of modern patent laws.


The 1980 decision in the case of Diamond v. Chakrabarty answers the question of whether living organisms could be patented, a ruling that Nard credited for launching the biotech industry.

The dispute arose when microbiologist Anand Chakrabarty, who was working for General Electric, filed a patent application for a genetically engineered bacterium capable of breaking down crude oil.

“It was controversial because the patent examiner denied the bacteria under the patent code because he said life is not patentable,” Nard explained.

The case was appealed and reversed, and then brought to the Supreme Court, where Chief Justice Warren Burger held that Chakrabarty’s bacteria was indeed patentable.

“For the Chief Justice, the issue was not living or non-living. The issue was whether Dr. Chakrabarty’s invention did indeed have markedly different characteristics than that which occurred naturally. And indeed, it was not something you would find in nature,” Nard said. “Right there, the court gave a huge boost, as you can imagine, to the biotech industry.”


Some 1.98 million patent applications were filed in 2012 at the world’s five largest patent offices, with China filing 526,412 applications, surpassing the U.S.’s 503,582 patents.

China’s State Intellectual Property Office overtook the U.S. Patent and Trademark Office as the largest patent office in the world, an outcome forecast in 2005 by Thomson Reuters researchers.
