Use the links above or do an advanced search in ppubs for:
(375/286.ccls. or 375/287.ccls. or 375/288.ccls. or 375/289.ccls. or 375/290.ccls. or 375/291.ccls. or 375/292.ccls. or 375/293.ccls. or 375/294.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.
