MARPAT Backfile Expansion Update

19. October 2012

In March 2012, CAS announced that the MARPAT database would be enhanced with English-, German- and Japanese-language patents from 1987. The addition of English- and German-language patents for 1987 is now complete. Processing of English- and German-language patents from 1985 and 1986 and Japanese-language patents from 1987 is continuing. We are pleased to report that Markush information from over 2,600 patent publications has been added to date.
