According to Item 2, Paragraph 1, Article 25 of People's Republic of China (PRC) Patent Law, the rules and methods of intellectual activities cannot be patented. Intellectual activity is a mental thinking movement. It directly acts on people's thinking, which can only produce results through people's thinking activities, or indirectly acts on nature through people's thinking as a medium, producing effects without the help of natural forces. Therefore, this kind of activity does not have technical characteristics and does not belong to the invention-creation mentioned in the patent law, so it cannot be granted a patent right. ?
I suggest that you compile the word memorization method into a book to indirectly protect your method in the form of copyright. Because copyright only protects the expression of the book, not its ideas. )
So far, there seems to be no effective way to protect these methods.
