1Opinion of the Court

DUNIWAY, Circuit Judge:

Proler Steel Corporation, Inc., plaintiff, appeals from a summary judgment for defendants in a patent infringement suit. The patent is the Proler reissue patent, Re. 25,034. Claim 9 is the only claim that is involved. It is conceded that defendants do not infringe claims 1 through 8 or claim 10. The trial court held that claim 9 is invalid on a number of grounds, and that defendants do not infringe it, assuming that it is valid. We hold that claim 9 is invalid as a matter of law, for want of invention, and we therefore do not pass upon any of the other questions…
