Common Citation Document

The Common Citation Document (CCD) application is a patent information tool developed by the Trilateral Offices to provide single point access to citation data for their examined patent applications. It consolidates the prior art cited by all participating offices for the family members of a patent application, thus enabling the search results for the same invention produced by several offices to be visualised on a single page.

The creation of the CCD application is part of an ongoing process of technical harmonisation led by the Trilateral Offices aimed at establishing an appropriate infrastructure to facilitate greater integration of the global patent system.
