Text: 19 CORRECTLY HELD INVALID BY THE DISTRICT COURT UNDER 20 35 U.S.C. § 103. 21 In Robintech, Inc. v. Chemidus Wavin, Ltd., supra at 834, the District Court concluded, as a matter of law, that claims 3-6 of the Sands-Broome patent were invalid for obviousness under 35 U.S.C. § 103. Chemidus also relied on claims 7 and 10 below, and these two were held invalid, but the appeal is apparently limited to 3-6. For the reasons set forth in that opinion, which we adopt as ours, we affirm the District Court's conclusion of patent invalidity. Chemidus attacks the District Judge's reliance on absence of synergism, urging that synergism has been criticized as a test of validity of a combination patent. The Supreme Court, however, uses it in the recent case, Sakraida v. Ag Pro, Inc., 425 U.S. 273, 282, 96 S.Ct. 1532, 1537, 47 L.Ed.2d 784 (1976), which the District Judge relies on. He shows so much else in support of his decision, in his findings of fact and conclusions of law, that we could treat the synergism test as irrelevant and reach the same result. 22
