Read more for required docs and patent fee schedule.
How much does a patent cost in China?
The cost of obtaining a patent in China, including government fees and professional fees, depends on the type of patent (invention, utility model, or design), the complexity of the application, and the service (e.g., filing, examination, registration, maintenance) you need.
Is it mandotory to register a copyright?
No, it isn’t. In China, copyright protection is automatic upon creating a work. However, registering your copyright with the Copyright Protection Center of China (CPCC) offers significant advantages, especially when addressing ownership disputes or infringement issues, notably with entities like China Customs or e-commerce platforms such as Alibaba.
How to initiate an IP infringement litigation?
Besides sharing case details and evidence with a Chinese registered lawyer, foreign IP owners should also notarize, legalize, and translate ID proof, board resolutions, POA, and evidence in advance for litigation before a court in China.
