There is some evidence that some form of patent rights was recognized in Ancient Greece. In 500 BCE, in the Greek city of Sybaris (located in what is now southern Italy), "encouragement was held out to all who should discover any new refinement in luxury, the profits arising from which were secured to the inventor by patent for the space of a year."[2] Athenaeus, writing in the third century CE, cites Phylarchus in saying that in Sybaris exclusive rights were granted for one year to creators of unique culinary dishes.[3]
In England, grants in the form of letters patent were issued by the sovereign to inventors who petitioned and were approved: a grant of 1331 to John Kempe and his Company is the earliest authenticated instance of a royal grant made with the avowed purpose of instructing the English in a new industry.[4][5] These letters patent provided the recipient with a monopoly to produce particular goods or provide particular services. Another early example of such letters patent was a grant by Henry VI in 1449 to John of Utynam, a Flemish man, for a twenty-year monopoly for his invention.[5]
The first Italian patent was awarded by the Republic of Florence in 1421.[6][7] The Florentine architect Filippo Brunelleschi received a three-year patent for a barge with hoisting gear, that carried marble along the Arno River in 1421.
