INPADOC Databases Enhanced with Japanese Patent Classifications, Current U.S. Classification and Japanese Legal Status

February  1st,   2012

The coverage of major patent classifications in INPADOC has significantly been enhanced with the addition of the Japanese patent classifications (FI-terms and F-terms), providing a considerable value to Japanese patent and utility model publications. At the same time the current US patent classification codes have been included into INPADOC, complementing the set of issued US classification codes. Prior art searching is now much more reliable for Japanese and US patent documents. 

The Japanese Patent Office (JPO) applies two completely independent national classification systems to classify Japanese patents and utility models: the IPC-based FI classification and the F-term classification. Both Japanese patent classifications became available in INPADOC on STN, providing an extremely useful tool to access Japanese patent literature. The Japanese patent classifications are available for 15 million Japanese patents and utility models back to 1965.

The coverage of the US national patent classification in INPADOC has been extended to include the current US classification codes for 9,3 million US applications. These codes are available for the complete backfile of US patent documents back to 1836.

For further details and search examples see the INPADOC News 2012/02: http://www.stn-international.com/inpadoc_news_201202.html

The European Patent Office has just started to provide legal status data for Japanese patents and utility models back to April 2011. We expect more than 90 different legal status events for Japanese publications. Use EXPAND JP/LSC to see a list of all Japanese legal status codes currently available in INPADOC.
