What is the Common Citation Document (CCD) application?
The Common Citation Document (CCD) application is a tool that provides a single point of access to citation data for the patent applications of the IP5 Offices. According to MPEP 901.07:
“The Common Citation Document (CCD) application allows users to see, in a single location, the prior art cited by the IP5 Offices for the family members of a patent application.”
This tool is particularly useful for patent examiners and applicants to efficiently review and compare citation data across multiple patent offices.
