Count number of patent applications
Posted: Mon Aug 19, 2019 2:03 pm
Dear PATSTAT community,
I am currently writing a research paper on the influence of open innovation on the innovation output of Unilever. The number of patents of Unilever is therefore necessary to my research. I would like to obtain the number of patents that Unilever filed or applied (not granted) per year from 2002 to 2019. Is it possible to write a query which would provide me with the information I need?
I have tried the EP full-text search database but failed. If there is better database for such patent data, please kindly inform me. Besides, since I am new to both PATSTAT and SQL every help is highly appreciated.
Best regards,
Karvey
