Pre-grant application missing

Dear Patentsview Team,

I hope you are doing well.

I was looking at the pregrant_published_application data and found that there are obvious missing data in that dataset. Attached is a summary table of number of applications in each year. It would be of great help to know why are there missing values before 2001 (there are probably missing after 2001 too). Thank you very much!

Best,

Luman

Hello Luman! We do not have…

Hello Luman! We do not have have pre-grant published application data before the year 2001. We source our data from the USPTO and they began releasing bulk XML data files for PG-Pubs in 2001. Please let us know what older pg_pubs data you find - we would be curious to check it out too!

Thank you,
PVTeam
