I want to know the answer to the following question:
What year did the "discoveries are property" concept appear in French law?
All the background I'm provided with is that "Section 1 of the French law of 1791 stated, "All new discoveries are the property of the author; to assure the inventor the property and temporary enjoyment of his discovery, there shall be delivered to him a patent for five, ten or fifteen years."". Is that enough to answer the question?
