PCI has been loaded as a replacement for DPCI on February 17, 2008
19. Februar 2008
Patents Citation Index(tm) (PCI) is a unique database of examiner citations, both patent and literature from 1973 to date. Coverage has been enhanced over time and currently covers 10 major patenting authorities, i.e. Belgium, European Patent Office, France, Germany, Japan, Netherlands, Spain, United Kingdom United States, World/PCT. Prior to May 1997, examiner and author citations were provided for 16 patent-issuing authorities.
PCI provides access to 98 million patent and 11 million literature citations found in more than 8 million patent families.
PCI contains bibliographic patent family data from the Derwent World Patents Index and all patents and literature cited by examiners, as well as references to citing patents. Coverage includes all patent-relevant areas of science and technology.
DPCI, which is replaced by PCI will continue to be available for another four weeks as a static file. During this period existing procedures can be adjusted to the new, enhanced file environment.
The new features:
- extended coverage
- stopwords are no longer used
- additional priority application numbers
- additional Thomson Scientific standard application numbers (/APTS and /PRTS)
- more focused data content
