Hi, it seems that the pypatent can only handle the patent issued after 1976.
When I want to search the patent issued before 1975, and specify ISD/1/$/1975, it always return error.
I noticed that in the USPTO website, user can manually chooose the after 1976 database or the 1790 full datebase.
Can we manually choose the full database in the pypatent?
