The new and enhanced DPCI file on STN has been released

24. January 2011

The enhanced DPCI database has been released on STN on January 23, 2011.

The coverage is substantially increased. It now provides patent citation information from 23 sources including Asian sources like Korea. Inventor, opposition, post-grant and third-party citations have been added as well.
In order to improve the support for current awareness searches, additional update codes are being provided.
The DPCI replaces the previous PCI file. It is backward compatible yet existing procedures like scripts may require adjusting in order to fully exploit the new features provided.
