We affirm Judge Dooling’s finding that Tensitron’s tension meter was “obvious” within the meaning of 35 U.S.C. § 103 and therefore not patentable. His well reasoned opinion is reported at 260 F.Supp. 457 (1966). It is unnecessary, therefore, for us to pass upon his finding that Bromley’s device infringed claims 2, 3, 5, and 6 of Tensitron’s patent.
