3. Evidence of unsuccessful efforts upon the part of a few others, not familiar with the prior art, to attain the result achieved by the patented device, of acceptance of licenses by manufacturers not shown to have made wide or successful use of it, and evidence of its utility and commercial success held insufficient to establish novelty in this case.
