Use the links above or do an advanced search in ppubs for:
(378/125.ccls. or 378/126.ccls. or 378/127.ccls. or 378/128.ccls. or 378/129.ccls. or 378/130.ccls. or 378/131.ccls. or 378/132.ccls. or 378/133.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.
