Re: Multiple companies

Hello Rutger, doing an analysis on a user-defined list of 3000 companies is not possible in PATSTAT Online because users can not upload their own list to our hosted data base. Options are: you purchase PATSTAT and install it on a local server. Or you find a "best common denominator in the patent dat...

Re: Patent count yearly per company

Hello Rutger, how would you calculate that indicator. For each application year ? Forward citations are available as a pre-aggregated attribute; one could make the sum and then normalise it over the number of applications - arriving at some kind of index that shows a "citation ratio". Or do you have...

Re: PATSTAT GLOBAL - REGISTER difference

Hello Mark, PATSTAT Global and PATSTAT Register do not contain the same data - but there is an overlap-. To have a good overview on the differences, I would recommend you to have a closer look at the data base model in the PATSTAT Global and PATSTAT Register data catalogs. You find them in the docum...

Re: Query Help for UK Patent Data

Hello Luca, kindly keep in mind that we do not have the resources to support individual researchers with drafting SQL queries for their research project.

(PSN_Sector quality)... inventors being flagged as applicants

Hello Tomas, The reason for the sudden dip (from application filing year 2012 to 2013) is the fact that inventors that were in previous years (appln_filing_year < 2013) also flagged as applicants started to be flagged as inventors only. Before 2013, its seem the default value was to flag all invento...
