By historical reasons the document codes used for the same kind of document
may differ from database to database
(e.g. a laid-open application in Canada (new law) is called CA-A in Derwent
WPI, but CA-AA in INPADOC and Chemical Abstracts).
As explained already by others, SK-B6 (INPADOC) means a Slovakian granted
patent.
