Hello Community!

I am looking for some archive files to replicate other researchers' work. 

Their work used "the persistent inventor ids ... from the `patent 20180528' from patentsview.org" and the inventor id in their files looks like a combination of the patent number and the sequence of the inventor (e.g. 3930273-1). 

My goal is to calculate the productivity of each inventor. To be specific, I am looking for one or multiple files in that version which include the patent number, the disambiguated inventor id and the grant year of the patent. Since the data dictionary in older versions might be different, I am not sure what files exactly I should request for. I am looking for files which include the listed variables above after merging. 

Thank you very much for your time!
