Use the links above or do an advanced search in ppubs for:
(378/45.ccls. or 378/46.ccls. or 378/47.ccls. or 378/48.ccls. or 378/49.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.
