1Opinion of the Court
NATHANIEL R. JONES, Circuit Judge.
These consolidated appeals involve two patents, in the field of bonded magnets, owned by Minnesota Mining and Manufacturing Company (3M). Walter S. Blume and the Electrodyne Company (defendants) appeal from judgments holding that Blume infringed 3M’s U. S. Patent No. 2,999,275 (275 patent) and thereby also breached an agreement not to compete (described by the-district court as the “noncompete agreement”). 3M appeals from a judgment hold ing its U. S. Patent No. 3,235,675 (675 patent) invalid for obviousness. 1 We affirm the judgments.
