The European Patent Office (EPO) has completed the INPADOC(PRS) and DOCDB harmonization project producing the new International Patent Documentation Database (INPADOCDB) on STN.

The new file offers a lot of new and enhanced content:

• About 63 million documents (old file: 49 million documents).
• Backfile back to 1836(US), 1879(DE), 1840(GB), 1900(FR), 1944(JP), etc.
• Many more abstracts, mostly in English.
• Cited references (patents and non-patent literature) for 12 offices. Citations from searches made at the EPO for BE, CH, EP, FR,GB, NL, TR and all WO are loaded as well as data from AU, DE, JP and US. 
• European classifications (ECLA, ICO, IDT).
• Improved Legal Status display.

Details on content enhancements, new search fields, new display formats, and major changes from INPADOC are available from the STN International website.
