Who gave legal right to inventions?

Legal rights to inventions are typically granted through patents, which are government-issued protections that give inventors exclusive rights to their inventions for a specified period. The authority to grant these rights varies by country, with organizations such as the United States Patent and Trademark Office (USPTO) in the U.S. and the European Patent Office (EPO) in Europe responsible for the patenting process. Patents encourage innovation by ensuring that inventors can benefit commercially from their creations.
