Backfile data is being added continuously backwards during the year 2000. English abstracts are added to French and German language applications within several weeks of their addition to the database.
Titles are available in all three languages in general.
Coverage includes all granted utility patents, defensive publications, design patents, reissue patents, statutory invention registrations, and plant patents. Complete Chemical Abstracts indexing for one equivalent U.S. chemical patent may also be included in a record. Abstracts and indexing for preprints appear in CAplus, CA, and associated CAS databases. In October 1999 we started with the loading of the backlog data. Now we have reached week 50 of 1992.
