Did the ancients attach importance to patent rights?

The ancients were very generous and didn't charge royalties, so they couldn't. But sometimes it is also out of the overall awareness of rights protection, such as paper, silk, porcelain and tea, which used to be made in China. So China made a lot of money from foreigners. No one will tell foreigners about these things, and officials and people will not take foreigners to places like paper mills, brick kilns and tea mountains, so we have sold these things for thousands of years. Copyright was emphasized in ancient times. Authors sell their works to publishers (bookstores). Generally speaking, bookstores do not copy from each other, but are more ethical.
