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 <strong>to</strong> the field code, e.g. /IPC5. Catchwords are<br />
available 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 corresponding Core Level (+COR)<br />
Here are some applications:<br />
Hierarchical search of the IPC at all hierarchy levels<br />
Simple query of defined IPC ranges<br />
Correlation of Advanced Level and Core Level codes is displayed in the IPC8 thesaurus<br />
Identification of suitable IPC codes through a catchword search<br />
The main on-line aids are: HELP THESAURUS (Thesaurus contents) and HELP RCODES (meaning and application of<br />
Relationship Codes).<br />
18.3.3.1 Limiting <strong>to</strong> invention information<br />
One important limiting option is <strong>to</strong> search by IPC for invention information. For old IPC codes (editions 1 <strong>to</strong> 7) the<br />
attributes ICM and ICS are available and for new IPC 8 codes INVENTION or I, all in the IPC.KW field:<br />
=> FIL INPADOCDB<br />
=> S G02C0005-08/IPC(S)(I OR ICM OR ICS)/IPC.KW<br />
467 G02C0005-08/IPC<br />
46889478 I/IPC.KW<br />
37020372 ICM/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 <strong>to</strong> 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 Limiting <strong>to</strong> Main IPC codes<br />
In the old IPC system all patent publications had one Main IPC code. In the new IPC system there is no Main IPC code<br />
any longer; however, the patent offices have the option <strong>to</strong> assign either a FIRST or a LATER attribute <strong>to</strong> each<br />
invention IPC code. Use and actual meaning of FIRST depends on the individual patent office and is only roughly<br />
comparable <strong>to</strong> that of a Main IPC code.<br />
