Catalogue of Differing Practices

The Catalogue of Differing Practices (CDP) is a tool aimed at identifying the differences in patent examination practice in the Trilateral Offices, as well as in the practice of KIPO (Korean Intellectual Property Office) and SIPO (State Intellectual Property Office of the People's Republic of China). It is also a first step towards a reference guide which allows the reader to quickly understand the practice in the other offices without requiring a detailed knowledge of the underlying legislative systems.

The CDP is part of an ongoing process intended to support work sharing and operational practice convergence between the participating offices.
