In China, patents can be obtained except for the following provisions that cannot be granted:

Which inventions can't be patented

Inventions and creations that violate national laws, social morality or hinder public interests will not be protected by patents in any country.

Scientific discoveries, methods and laws of intellectual activities, methods of diagnosis and treatment of diseases, species of animals and plants, substances obtained by nuclear transformation, etc. All belong to the category explicitly prohibited by China's patent law.

In addition, inventions that cannot be implemented, such as perpetual motion machines, cannot be licensed. Literature, artistic works, musical works and film and television works are not protected by patents, but they can be protected by copyright. Trademark, logo, slogan and other characteristic signs that distinguish the source, place of origin and manufacturer of goods can be protected by trademark law and generally do not need to apply for a patent.
