Derwent World Patents Index has been enhanced with Japanese Patent Classification Data

22. December 2008

Japanese Patent Classifications (FI-Terms) and FTERMs have been introduced in the Derwent WPI database (files WPINDEX/WPIDS/WPIX) in December 2008. About 5.25 million Japanese patents in about 4.5 million Derwent WPI documents have been equipped with current Japanese Classification data for 1966 to 2007.

 The 2008 data will be added in January 2009, and during February 2009, regular updates will start to include the Japanese classification data. For more details refer to HELP JPC at an arrow prompt when in the database, or to the Featured Highlights section at
