In Japanese patent law, F-term is a system for classifying Japanese patent documents according to the technical features of the inventions described in them. It is not a replacement for the International Patent Classification (IPC) or other patent classifications, but complements other systems by providing a means for searching documents from different viewpoints.^{[citation needed]} A symbol attached to a patent document, indicating that the invention disclosed in the document has a particular technical feature, is also called an F-term.^{[citation needed]}

-In [[Japanese patent law]], '''F-term''' is a system for [[classification|classifying]] [[Japan]]ese [[patent]] documents according to the technical features of the [[invention]]s described in them.  It complements the [[International Patent Classification]] (IPC) system by providing a means for searching documents from a different viewpoint than that provided by the IPC system.

-The F-term system was developed in [[1987]] by the [[Japan Patent Office]] (JPO) and it is maintained by the same body.  A symbol attached to a patent document, indicating that the invention disclosed in the document has a particular technical feature, is also called F-term.
-The F-term classification system consists of '''themes''' and '''terms'''.
-The coverage area of the IPC is divided into approximately 2900 categories, each of which is called a theme, and each theme spans a range of IPC subgroups.  A theme identified by the title describing the range or the '''theme-code''' which consists of five digits allocated uniquely to each theme; for example, a theme spanning IPC range A01K 87/00--87/06 is identified by its title "[[Fishing rod]]s" and its theme-code "2B019".
-Each theme has a number of viewpoints and each document is classified repeatedly for each viewpoint in the respective theme.  For example, Theme 2B019 "Fishing rods" has the following twelve viewpoints: structures, [[raw material]]s, surface processing and patterns, illumination, accessory implements, protective covers, plugs, fishing line guides, top guides, mounting cylinders, plate configurations and pipe elements.
-From each viewpoint, documents are classified into several groups and labeled with a four-digit code called the "term" or "F-term".  For example, from viewpoint "structures", all fishing rod documents are classified into fourteen groups such as AA01 "Cross-sectional configurations", AA03 "Built-in reels at the bottom of the rod", etc.; from viewpoint "raw materials", all fishing rod documents are classified into 23 groups such as AB01 "Rods of fiber-reinforced plastic (FRP)", AB41 "Natural materials combined with fiber-reinforced plastic (FRP)", etc.
-All terms concerning a theme are put into a tabular form called an "F-term list", which are available online, e.g., [http://www5.ipdl.ncipi.go.jp/pmgs1/pmgs1/!frame_E?hs=1&gb=2&dep=3&sec=2B&cls=019&scls=&mgrp=&idx=&sgrp=&sf=&bs=&dt=&wrd=&nm= 2B019].  (Some descriptions of F-terms may seem strange because of incorrect translation from the original [[Japanese language|Japanese]])
-== A fictional example ==
-Below is a, fictional, example of classifying a patent application within the F-term system.  The fictional example of a cooking recipe database will be used as this avoids the need for any subject-specific knowledge.
-The (Fictional) IPC-style classification of recipes may be as follows:
- X99Y 1/00  Dishes
- X99Y 1/02  . Meat dishes
- X99Y 1/04  . . comprising beef
- X99Y 1/06  . . comprising pork
- X99Y 1/08  . . comprising lamb
- X99Y 1/10  . comprising seafood
- X99Y 1/12  . comprising vegetables
-This classification of recipes is based on a single viewpoint - the main ingredient of the dishes.  Hence we can browse all recipes of meat dishes by selecting recipes labeled "X99Y 1/02", "X99Y 1/04" and "X99Y 1/06", and likewise we can browse all recipes of beef dishes by selecting recipes labeled "X99Y 1/04".
-However, the system does not allow the user to find all Chinese recipes, or all [[halaal]] lamb recipes, because the system is based on a single viewpoint.  This is solved by the F-term system by the use of multiple viewpoints.
-A fictional ''F-term'' classification of recipes may be as follows:
-Z999  Dishes (X99Y 1/00--1/12)
- AA    INGREDIENTS
- AA11  Meat
- AA12  . Beef
- AA13  . Pork
- AA14  . Lamb
- AA21  Seafood
- AA22  . Fish
- AA31  Vegetable
- BB    CUISINE
- BB41  Asian
- BB42  . Chinese
- BB43  . . Cantonese
- BB44  . Turkey
- BB51  European
- BB52  . French
- BB53  . Italian
- CC    COOKING
- CC11  Boiled
- CC21  Fried
- CC31  Roasted
- CC41  Steamed
- DD    SPECIAL
- DD11  Haraal
- DD12  Vegetalian
-"9Z999" identifies an F-term sheet, or '''theme'''.  "X99Y 1/00--1/12" in the parentheses indicates that the sheet covers the IPC range X99Y 1/00--1/12.  "AA", "BB", or "CC" identify the different viewpoint of the '''theme''' and the combination of two letters and two numbers "AA11" etc. identifies features viewed from a specific viewpoint.  This 4-symbol construction is known as an ''F-term''.  We can therefore find all Chinese recipes by selecting recipes having an F-term of "BB42".
-Since all applicable ''F-terms'' are applied to a given document a boolean-logic search can be used to find combinations of features - for example to find ''Halaal Lamb'' recipes a search can be made for recipes having both "AA14" and "DD11" F-terms.
