Match of PATSTAT data (2019 spring) and PatentsView (jan 2019) is discussed here, with focus on how this match can help to enrich PATSTAT data with information not contained in USPTO patents (and the other way round).

'statutory invention registration' missing
publishing patent applications on which they no longer felt they could get patents.
By publishing the patent applications, they helped ensure that the inventions were in the public domain
and no one else could subsequently get a patent on them
