The IPC Thesaurus and its applications<br />
Together with the IPC8, an IPC thesaurus for IPC versions 1-8 were included in all STN patent<br />
files. The IPC Thesaurus is a very helpful tool to search or display ranges from the IPC hierarchy.<br />
Possible applications for the IPC Thesaurus:<br />
� hierarchical IPC searches can be carried out on all hierarchy levels<br />
� defined ranges within the IPC can easily be searched for<br />
� the IPC8 Thesaurus display considers the correlation between Advanced and Core Level<br />
� the IPC Thesaurus includes the WIPO IPC keyword index; by using key words appropriate<br />
IPC codes can be identified<br />
Valuable online help is provided by HELP THESAURUS and HELP RCODES (information<br />
about the content of the thesaurus and on the meaning and usage of Relationship Codes).<br />
Example: Hierarchical search with the 2-dot subgroup G03F 7/027, all appropriate sub-groups<br />
should be included in the search<br />
Excerpts from the IPC8 hierarchy of class G03 - Photography<br />
G03F 7/027 ..non-macromolecular photopolymerisable compounds Core<br />
G03F 7/028 …with photosensitivity-increasing substances Core<br />
G03F 7/029 ....Inorganic compounds; Onium compounds Core<br />
G03F 7/031 ....Organic compounds not covered by group G03F 7/029 Core<br />
G03F 7/032 ...with binders Core<br />
G03F 7/033 ....the binders being polymers Core<br />
G03F 7/035 ....the binders being polyurethanes Advanced<br />
G03F 7/037 ....the binders being polyamides or polyimides Advanced<br />

1. An EXPAND on the IPC symbol<br />
shows if the symbol is part of the<br />
IPC thesaurus. The column AT hints<br />
to the IPC thesaurus.<br />
1= old entry IPC1-7<br />
2= IPC8<br />
2. The relationship code +NT displays<br />
=> E G03F0007-027+NT/IPC<br />
all „narrower terms“.<br />
E50 13917 --> G03F0007-027/IPC<br />
. . Non-macromolecular photopolymerisable compounds<br />
having carbon-to-carbon double bonds, e.g. ethylenic<br />
compounds (G03F0007-075 takes precedence)<br />
