(44/354.ccls. or 44/355.ccls. or 44/356.ccls. or 44/357.ccls. or 44/358.ccls. or 44/359.ccls. or 44/360.ccls. or 44/361.ccls. or 44/362.ccls. or 44/363.ccls. or 44/364.ccls. or 44/365.ccls. or 44/366.ccls. or 44/367.ccls. or 44/368.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.
