Use the links above or do an advanced search in ppubs for:
(375/232.ccls. or 375/233.ccls. or 375/234.ccls. or 375/235.ccls. or 375/236.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.
