Question in terms of IPC classification on Patstat
Posted: Wed Jul 13, 2016 11:57 am
Hello,
I'm using an offline version of Patstat 2015. I wanted to know, if there is a posibility to get some kind of main IPC class of an EP-patent. I know that in Patstat is a table called tls209_appln_ipc with the column ipc_position. I think it exhibits the place of naming for the IPC class in an patent specification.
At the USPTO or in german patent data you can find a main class which the patent is assigned to.
