Use the links above or do an advanced search in ppubs for:
(226/118.1.ccls. or 226/118.2.ccls. or 226/118.3.ccls. or 226/118.4.ccls. or 226/118.5.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.
