SIPO and the European Patent Office (EPO) decided to renew the MOU on beefing up patent classification cooperation for another 6 years.

According to the MOU, SIPO would classify all invention patent applications in technology field via CPC since January this year, and share the relevant classification data with EPO. EPO continues to provide specific CPC classification training for SIPO. Both SIPO and EPO would hold regular work group meeting to discuss topics on quality assurance, information technology and training exchange.

Under the original MOU, SIPO has tried to classify 470,000 newly published patent documents via CPC classification.
