1Opinion of the Court
SANBORN, Circuit Judge.
The important question for decision in these cases is whether the determination by the District Court that claims 1, 3, 5, 6, 16 17 and 24 of United States Letters Patent No. 1,949,098 issued to Albert W. Becker on February 27, 1934, for a “Windshield Clearing Device,” upon an application filed February 6, 1928, and claims 9, 13 and 14 of United States Letters Patent No. 2,206,-814, issued to Erwin C. Horton on July 2, 1940, for a “Windshield Clearing System,” upon an application filed August 12, 1935, are void for want of invention, is clearly erroneous.
