A prosecution brief and a defense brief are argued independently, then a neutral judge returns an HONEST verdict \u2014 SUPPORTED, NOT SUPPORTED, or INCONCLUSIVE \u2014 with element-by-element analysis and openable cited sources. Serves EITHER side (assertion or defense). A verdict reflects the openable record, not adjudicated infringement; similarity is never proof of claim practice.",
