MARPAT Backfile Expansion Update

22. February 2013

CAS continues to expand backfile content in MARPAT with unique information. MARPAT now includes French-language patents from 1985 to 1987. This is in addition to the previously announced English- and German-language patents from that period. We continue processing Japanese-language patents from 1987. To date, Markush information has been added from over 4,200 patent publications.
