Chemical Abstracts Service.
The CASREACT file on STN International was expanded to include organic chemical reactions from patents published since January 1991. The file is produced by Chemical Abstracts Service. In early 1992, STN will expand with the addition of the PATOS series of patent databases from Bertelsmann Information Service and WilaVerlag. The three databases in the series - PATOSDE, PATOSEP and PATOSWO - contain more than two million patents from the German Patent Office, the European Patent Office and the World Intellectual Property Organization, respectively.
