Use the links above or do an advanced search in ppubs for:
(504/334.ccls. or 504/335.ccls. or 504/336.ccls. or 504/337.ccls. or 504/338.ccls. or 504/339.ccls. or 504/340.ccls. or 504/341.ccls. or 504/342.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.
