Authoritative analysis by a famous school teacher: Chapter 15 P175 patent term.

The Patent Law has the following views on the protection period of patent rights. The term of invention patent rights is 20 years, and the term of utility model patent rights and design patent rights is 10 years, both calculated from the date of application.

The validity period of a registered trademark is ten years, calculated from the date of approval. You can renew and pay the renewal fee six months before the expiration of the validity period. Each renewal is still valid for ten years. There is no limit to the number of renewals. If the application is not submitted within this period, a 6-month extension period may be granted. If the renewal of registration is not submitted within the extension period, the Trademark Office will cancel the registered trademark and make an announcement.
