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 in a single page.

It currently includes data from the Trilateral offices: the EPO, the JPO and the USPTO.
