Types of search<br />
The IPC field holds the classification codes and catchwords of the current edition of the IPC (edition 8). To access<br />
earlier editions the number of the desired edition must be appended to the field code, e.g. /IPC5. Catchwords are<br />
<strong>available</strong> from edition 5.<br />
These Relationship Codes can be used for SEARCH and EXPAND:<br />
Full class title (+INDEX).<br />
Full class title and IPC edition (+ED)<br />
Full class title and broader terms (+TI)<br />
Narrower terms (+NT), Related terms (+RT), Broader terms (+BT) or Hierarchy (+HIE)<br />
Browse (+BRO) the full class; (+BRO5) 5 Broader and 5 Narrower terms; browse forward and backward<br />
(+NEXT (n), +PREV (n))<br />
Keyword terms (+KT)<br />
All related terms (+ALL)<br />
All Advanced Level (+ADV)<br />
All correspond<strong>in</strong>g Core Level (+COR)<br />
Here are some applications:<br />
Hierarchical search of the IPC at all hierarchy levels<br />
Simple query of def<strong>in</strong>ed IPC ranges<br />
Correlation of Advanced Level and Core Level codes is displayed <strong>in</strong> the IPC8 thesaurus<br />
Identification of suitable IPC codes through a catchword search<br />
The ma<strong>in</strong> on-l<strong>in</strong>e aids are: HELP THESAURUS (Thesaurus contents) and HELP RCODES (mean<strong>in</strong>g and application of<br />
Relationship Codes).<br />
18.3.3.1 Limit<strong>in</strong>g to <strong>in</strong>vention <strong>in</strong>formation<br />
One important limit<strong>in</strong>g option is to search by IPC for <strong>in</strong>vention <strong>in</strong>formation. For old IPC codes (editions 1 to 7) the<br />
attributes ICM and ICS are <strong>available</strong> and for new IPC 8 codes INVENTION or I, all <strong>in</strong> the IPC.KW field:<br />
=> FIL INPADOCDB<br />
=> S G02C0005-08/IPC(S)(I OR ICM OR ICS)/IPC.KW<br />

17720910 ICS/IPC.KW<br />
L7 467 G02C0005-08/IPC(S)(I OR ICM OR ICS)/IPC.KW<br />
The search query may be limited to the IPC8 attribute for the SDI search profile:<br />
=> S G02C0005-08/IPC(S)(I)/IPC.KW<br />
467 G02C0005-08/IPC<br />
46889478 (I)/IPC.KW<br />
L8 416 G02C0005-08/IPC(S)(I)/IPC.KW<br />
18.3.3.2 Limit<strong>in</strong>g to Ma<strong>in</strong> IPC codes<br />
In the old IPC system all patent publications had one Ma<strong>in</strong> IPC code. In the new IPC system there is no Ma<strong>in</strong> IPC code<br />
any longer; however, the patent offices have the option to assign either a FIRST or a LATER attribute to each<br />
<strong>in</strong>vention IPC code. Use and actual mean<strong>in</strong>g of FIRST depends on the <strong>in</strong>dividual patent office and is only roughly<br />
comparable to that of a Ma<strong>in</strong> IPC code.<br />
