CAplus enhanced with French and German abstracts

French- and German-language abstracts in basic patents from the European Patent Organization (EPO) are now included in CAplus. These abstracts are only included when an English-language abstract is not available.

In patents that are indexed by CAS, French- and German-language abstracts are replaced by English versions shortly after the record is added to CAplus. French- and German-language abstracts are searchable in Basic Index (BI) in their respective languages until replaced by the English versions. Records are added to CA only after indexing and the addition of English-language abstracts is complete.

Patents with selectively covered International Patent Classification (IPC) codes that are not indexed by CAS retain the original French- and German-language abstracts in CAplus. These records are not included in CA.
