Linking Patstat to Compustat and/or CRSP?
Do you have any insight on how I can link an extraction of Patstat data with Compustat and/or CRSP? I am trying to link a database to the Compustat or CRSP database systems.

By company name (`conm` or `conml` in Compustat). However, Compustat is consolidated, PATSTAT is not. In other words, Compustat only contains ultimate parents/mothers but there is nothing that says that subsidiaries/daughters can not apply for patents. In fact, some companies may even have a subsidiary specifically for doing R&D and applying for patents.
You could use NBER, but NBER only has information for Compustat North America, and only up to 2006.
