Why was Filippo Brunelleschi's 1421 patent historically significant?

Filippo Brunelleschi’s 1421 grant is historically significant because it is recognized as the first recorded patent for an industrial invention.

Granted in Florence, this privilege provided the architect and engineer with a three-year monopoly on the manufacture of a specialized barge equipped with hoisting gear, which was designed to transport marble. This act is considered a foundational moment in the history of intellectual-property law, as it established the precedent of a government granting an inventor the exclusive right to exclude others from making, using, or selling their invention for a limited period. Following this grant, the practice of issuing such privileges to inventors spread from Italy to other European nations over the next two centuries, eventually evolving into the modern, standardized patent systems used globally today.1
