Can language and written works be patented? For example, how to apply advertising language? Hope to have a professional answer! ! !

1. Patents are only inventions, utility models and designs, and languages are not patent objects, so they can only be protected by copyright law, and they cannot apply for patents. 2. Because the advertising language is short and you don't apply for naturally generated copyright, the degree of protection is relatively low, unless people are really like you. 3. Trademark law can be used for protection, but strictly speaking, the trademark law does not allow the registration of advertising words, but if the advertising words are not exaggerated, they can apply.
