Content Why FI/F-term? Overview of patent classification systems What is FI? What is F-term? Revision of FI/F-term Finding FI/F-term 2

Why FI/F-term? Annually about 350,000 patent applications in Japan (not including PCT applications) Totally about 20,000,000 documents About 75% of domestic applications have no patent families Huge amount of prior art! 450000 400000 350000 300000 250000 200000 150000 100000 50000 0 1974 1977 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 3

Why FI/F-term? 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 4

Content Why FI/F-term? Overview of patent classification systems What is FI? What is F-term? Revision of FI/F-term Finding FI/F-term 5

Overview of patent classification systems System Governance Number of Entries IPC IPC/CE (Committee of Experts); supervised by WIPO 70K Documentation coverage - almost all patent docs published worldwide FI/F-term JPO 190K/ 380K - JP docs CPC EPO/USPTO 250K (main trunk / 2000 series = 160K/ 80K) - the subset of "min-pct" documentation in one of the three EPO languages - patent docs classified by CPCNO 6

Relationship between IPC and FI/F-term IPC FI F-terms (Multi-dimensional viewpoints) View point 1 AA01, AA02, Theme View point 2 BB01, BB02, View point 3 CC01, CC02, 70,000 entries 190,000 entries 380,000 entries 7

Content Why FI/F-term? Overview of patent classification systems What is FI? What is F-term? Revision of FI/F-term Finding FI/F-term 8

What is FI? IPC FI (File Index) [Features] Subdivision of IPC Consists of IPC groups & IPC-based subdivisions Largely based on the latest version of IPC, but some are based on old version, e.g. IPC4 Uses a dot hierarchy like IPC Covers all the fields of IPC(A section to H section) 70,000 entries 190,000 entries Similar to CPC main trunk (160,000 entries) Biannual revision Backlog reclassification 9

FI - notation IPC symbol ex) G06F 9/00 IPC symbol + extension symbol ex) G06F 9/00, 320 IPC symbol + extension symbol + file discrimination symbol ex) G06F 9/00, 320 A IPC symbol + file discrimination symbol ex) B60G 17/015 A example of FI subdivisions for G06F9/00 (source: www.ipdl.inpit.go.jp/homepg_e.ipdl ) 10

FI Symbol (Extension symbol) Further subdivisions of IPC subgroups Indication with 3-digit numbers Hierarchical dots followed by IPC symbols Example: A01D HARVESTING; MOWING 34/ 00 Mowers; Mowing apparatus of harvest 34/ 24 Lifting devices for the cutter-bar 101 Co-operating of the machine 103 Actuating by sensing fields or stumps 104 Mechanism for preventing hunting 11

FI Symbol (File Discrimination Symbol) Further subdivisions under IPC subgroups or extension symbols Indication with a letter from A to Z Creation of symbol Z (others) is necessary No dot means 1 dot below IPC subgroups et al. Dot number means a hierarchical level within file discrimination symbols Example A01C PLANTING; SOWING; FERTILISING 1/ 00 Apparatus, or methods of use A Preparation for adjusting growth B Chemical treatment Z Others 12

Content Why FI/F-term? Overview of patent classification systems What is FI? What is F-term? Revision of FI/F-term Finding FI/F-term 14

What is F-term? Increasing number of patent documents Limits of subdivision of of IPC (FI) Inadequate segmentation --> FI is subdivided from only Subdivision the viewpoint of single of IPC viewpoint Need for efficient search Development of complex or combined technologies Invention of F-term as computer-based multi aspect search indexes 15

Relationship between IPC and FI/F-term IPC FI F-terms (Multi-dimensional viewpoints) View point 1 AA01, AA02, Theme View point 2 BB01, BB02, View point 3 CC01, CC02, 70,000 entries 190,000 entries 380,000 entries 16

What is F-term? Indications comprised of 2 letters selected from A to Z (called Viewpoint ) and 2 numerals selected from 00 to 99 Around 380,000 entries (total of all themes) Similar to CPC 2000 series (80,000 entries) F-terms (Multi-dimensional viewpoints) View point 1 AA01, AA02, View point 2 BB01, BB02, View point 3 CC01, CC02, Revised annually Backlog reclassification 17

Concept of theme A certain technical area (Total 2,600 Themes) Around 1,800 themes out of 2,600 have F-terms A theme has a certain FI coverage A theme consists of a theme code and a subject of the theme corresponding the FI coverage A theme code is expressed as 5-digits consisting of alphanumeric characters Example: Theme code: 3E003 FI coverage: B65B 5/00-5/12 Subject of the theme: Container packaging and wrapping operation 18

F-terms - notation Example: 3E067 AB01 theme code view point figure theme code: represents a technical field view point: analyses the theme (material, purpose, operation, manufacturing, etc.) figure: subdivides the viewpoint 19

F-terms - notation Example: 3E067 AB01. A theme code view point figure additional code theme code: represents a technical field view point: analyses the theme (material, purpose, operation, manufacturing, etc.) figure: subdivides the viewpoint additional code: subdivides each term code 20

F-terms - notation Example: 3E067 AB01 theme code view point figure 2 = Residual technology (2B, 2C, 2D,...) 3 = Mechanics (3B, 3C, 3D, 3E,...) 4 = Chemistry (4B, 4C, 4D, 4E, 4F...) 5 = Electricity (5B, 5C, 5D, 5E,...) 21
