Is there a way I could get application date before 1974?

 

Hello,

 

I just downloaded application.tsv file.

And it looks like there is a discontinuity between 1973 and 1974 (the number of patents increased from 8,396 to 38,522).

So I was wondering if there is any way I could get some application information before 1974. Or is this just because the original patent data doesn't have much information before 1974?

 

Thanks in advance.

source bulk data

Hi m.mark,

The patent office's bulk xml files starts with 2001 for applied patents (all applications, not just the ones that were granted).  The granted bulk files start with 1976.  The patentsview database is built from these files, both sets are listed on https://bulkdata.uspto.gov/  I think the pre-1976 data in application.tsv would have come from the granted patents from 1976 on (where the application was from the previous two or three years).  application.tsv  wouldn't have applications from 1973 and 1974 that didn't become patents or the 1973-74 ones that became granted patents before 1976.  As far as I know there isn't a bulk source of earlier data.  Here's a page showing statistics going back to 1963 if that helps any https://www.uspto.gov/web/offices/ac/ido/oeip/taf/us_stat.htm
