The International Patent Classification IPC is hierarchically structured
On the first level are the 8 sections A to H. The classes and subclasses follow. The last level are main group (/00) and subgroups (z.B. /08).
The IPC G05B19/4093 is defined like this:
|Subclass||G05B||CONTROL OR REGULATING SYSTEMS IN GENERAL; FUNCTIONAL ELEMENTS OF SUCH SYSTEMS; MONITORING OR TESTING ARRANGEMENTS FOR SUCH SYSTEMS OR ELEMENTS|
|Main group||G05B0019/00||Programme-control systems|
|Subgroup (2)||G05B0019/18||Numerical control (NC), i.e. automatically operating machines, in particular machine tools, e.g. in a manufacturing environment, so as to execute positioning, movement or co-ordinated operations by means of programme data in numerical form|
|Subgroup (3)||G05B0019/4093||characterised by part programming, e.g. entry of geometrical information as taken from a technical drawing, combining this with machining and material information to obtain control information, named part programme, for the NC machine|
classifications have been adapted to 4 digits with leading zeroes. They are now searchable as G05B0019/4093.
This was done to unify with the CPC that has been formatted like this from the beginning.
Queries containing IPCs with main or subgroups (containing a / in the IPC symbol) have been adapted automatically.
Please check quieries containing truncation or shorter IPCs and correct them (IC=G05B019 will now be IC=G05B0019).
There is no distinction between Main or First IPC (Field MC) and All IPCs (IC) anymore in this format.
