Use the links above or do an advanced search in ppubs for:
(182/178.1.ccls. or 182/178.2.ccls. or 182/178.3.ccls. or 182/178.4.ccls. or 182/178.5.ccls. or 182/178.6.ccls.)
This will show what classes derive from the input. Ex: entering 43/42.24 shows the derived classes and the search that can be used to find patents or patent applications in those subclasses.
