Welcome to PatCit

Building a comprehensive dataset of patent citations

Patents are at the crossroads of many innovation nodes: science, industry, products, competition, etc. Such interactions can be identified through citations in a broad sense.

It is now common to use front-page patent citations to study some aspects of the innovation system. Good news, there is much more buried in the front-page Non Patent Literature (NPL) citations and in the patent text itself1. patCit extracts and structures these citations.
