1Opinion of the Court
MURRAH, Circuit Judge.
This is an appeal from a judgment of the District Court of Kansas, holding invalid for lack of invention and for anticipation, appellant’s Patent 2,211,173 for improvement in pipe coupling, referred to as a tool joint. In so holding, the trial court did not reach or decide appellant’s claim that appellee Hughes Tool Company’s “Counter Bore Weld Tool Joints” infringed his patent.
