On 31 March 2014, the State Intellectual Property Office of China (SIPO) launched a new online system (CE-PCT) for filing international applications with SIPO as receiving office. According to an official announcement (Chinese only), the system includes various functions relating to the submission of new applications and intermediate documents, search and preliminary examination, enquiries, receipt of notifications and online fee payment.
WIPO's PCT-SAFE electronic filing software, used at SIPO for online submission of PCT applications prior to the launch of the new system, will continue to exist in parallel. However, when the PCT-SAFE system is used for filing an international application, the applicant will have to submit the relevant intermediate documents in printed form. Further information can also be found in this notice (Chinese only).
