Community Designs - RT*M

It has been many years now since OHIM published their Guidelines on Invalidation cases.  However, more recent and comprehensive (though less authoritative) guidance on design invalidity, both as to substance and procedure, can be found in their relatively new "Manual concerning the Examination of Design Invalidity Applications".  This features, amongst other things, guidance on functional designs based on the Lindner Chaff cutters decision R 690/2007-3 discussed here.  Well worth a read before attempting to prepare an application to invalidate.
