Annually about 350,000 patent applications in Japan (not including PCT applications)Totally about 20,000,000 documentsAbout 75% of domestic applications have no patent families
Huge amount of prior art!

1977:Strasbourg Agreement entered in force in Japan
1978: IPC officially introduced at JPO– growing numbers of patent documents– JPO examiners subdivide files (using alphabetic letters A - Z)– start of "File Index" (FI) classification
1984: "paperless office" project– computerised search system– new search indexes: File Forming Terms (F-terms)– to improve search efficiency
Why FI/F-term?

Subdivision of IPC Consists of IPC groups & IPC-based subdivisionsLargely based on the latest version of IPC, but some are based on old version, e.g. IPC4Uses a dot hierarchy like IPCCovers all the fields of IPC(A section to H section)

Development of complex or combined technologies
Increasing numberof patent documents
•Limits of subdivision of IPC (FI)
· · · Inadequate segmentation
· · · Subdivision of single viewpoint
Invention of F-term as computer-based multi aspect search indexes
• Limits of subdivision of IPC (FI)
--> FI is subdivided from only the viewpoint of IPC
