Cooperative Patent Classification System

UPDATE


In September 2014, the USPTO and KIPO (Korean IP Office) inked an agreement to work together on the CPC. KIPO will fully CPC classify all new patent applications and utility models, but no mention of back-file data. The CPC system is gaining wide acceptance. It definitely has the detail needed to replace the US system, and then some. We're still studying and learning the details, and the USPTO decision for the two year overlap (CPC/USC) makes more sense to us (it gives us more time, too. 1 year down, 1 to go). The EPO seems to have completed most, if not all of the their ECLA to CPC translations and CPC assignments, and unlike the ECLA data, the EPO's CPC data have been added to DOCDB for all countries they handle. We think it's a wonderful addition to the data, and our compliments and thanks go to the EPO!
