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.
