Use the links above or do an advanced search in ppubs for:
(534/550.ccls. or 534/551.ccls. or 534/552.ccls. or 534/553.ccls. or 534/554.ccls. or 534/555.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.
