(254/2r.ccls. or 254/3r.ccls. or 254/3b.ccls. or 254/3c.ccls. or 254/4r.ccls. or 254/4b.ccls. or 254/4c.ccls. or 254/5r.ccls. or 254/5b.ccls. or 254/5c.ccls. or 254/6r.ccls. or 254/6b.ccls. or 254/6c.ccls. or 254/7r.ccls. or 254/7b.ccls. or 254/7c.ccls. or 254/8r.ccls. or 254/9r.ccls. or 254/9b.ccls. or 254/9c.ccls. or 254/10r.ccls. or 254/10b.ccls. or 254/10c.ccls. or 254/8b.ccls. or 254/8c.ccls. or 254/2b.ccls. or 254/2c.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.
