The Common Citation Document (CCD) application aims to provide single point access to up-to-date citation data relating to the patent applications of the IP5 Offices. 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 visualized on a single page. The creation of the CCD application is part of an ongoing process of technical harmonization at international level aimed at establishing an appropriate infrastructure to facilitate greater integration of the global patent system. Here is a link to the CCD.
