Since January 2013, CPC (Cooperative Patent Classification) has been launched between the European Patent Office (EPO) and the United States Patent and Trademark Office (USPTO). Until now, the USPTO had been using the highly unique United States Patent Classification (USPC). With the start of the CPC, it can be said that the USPTO compromised to a classification system that follows the International Patent Classification (IPC). The EPO and USPTO hope to eliminate duplicated work and share information. Also, in understanding the classification system and determining the research classification, there should be a reduction in burden for the general user. In the future, it is suggested that there may be a certain influence on IPC reform. Here we give a general overview of the events leading to the CPC system, a summary of the classification system, browsing the classification table, a search strategy, etc.
