Types of protection

Invention Patent: An Invention Patent is for new technical solutions or improvements to a product or a process with practical applicability for a term of 20 years from the date of filing.

Utility Model Patent: A Utility Model Patent is similar to an invention patent but its protection is limited to products with new shape or structural physical features. The maximum term of protection is 10 years from the filing date.

Design Patent: A Design Patent cannot be published overseas or in China and cannot have been publicly used in China. If a company's products are sold in China before filing for registration, this will destroy the ‘novelty’ of the patent. Design patents are valid for 10 years.
