The Patent Re-examination Board (PRB) under the State Intellectual Property Office of China (SIPO) has now also launched an English website. This website gives a brief introduction to the structure and tasks of the PRB, which is mainly in charge of dealing with re-examination and invalidation cases.
The search interface which provides public access to the decisions taken in re-examination and invalidation cases is currently only available in Chinese language. A step-by-step search guide which shows in detail how to use this source without knowledge of the language is available on the EPO's virtual helpdesk on Asian patent information.
