China – Agreement To Adopt New International Patent Classification System.
25 July, 2013

 

On June 4th  2013, the China State Intellectual Property Office (“SIPO”) agreed to start using Cooperative Patent Classification (CPC) to classify newly published invention patent applications. The changes will bring China in line with the standard used by USPTO and EPO, meaning 70 to 80 percent of all patent applications worldwide will be classified with the same system. At the moment 45 patent offices around the globe also use CPC.

 

Beginning January 2014, SIPO will classify newly published invention patent applications in selected technical fields and by January 2016 newly published invention patent applications from all technical fields will be classified by using CPC. 

 

CPC, which is based on the former European Classification (ECLA), is currently the most comprehensive classification system with 250,000 subclasses compared to ECLA’s 130,000 subclasses. A more comprehensive and detailed classification system will help patent examiners conduct more efficient prior art searches and reduce the number of unmerited patent applications. It is also beneficial to applicants because a unified system helps them reduce costs.
