I want to know the answer to the following question:
When did Sybaris offer patents?
All the background I'm provided with is that "Jewish law includes several considerations whose effects are similar to those of modern intellectual property laws, though the notion of intellectual creations as property does not seem to exist – notably the principle of Hasagat Ge'vul (unfair encroachment) was used to justify limited-term publisher (but not author) copyright in the 16th century.". Is that enough to answer the question?
Answer: no
