B. F. Goodrich Co. v. United States Rubber Co‪.‬

This is an appeal from a judgment for defendant in an action brought by the B. F. Goodrich Company against the United States Rubber Company for infringement of U.S. Patent No. 2,587,470 relating to a tubeless tire for automobiles. The patent was issued to one Herzegh, an employee of Goodrich, in 1952 on an application filed in 1946. The District Judge has filed a comprehensive opinion in which the facts are carefully and correctly set forth and analyzed and the prior art is reviewed at length. He held that the patent was invalid for lack of invention over the prior art, that its claims were void for indefiniteness and that, even if valid, it was not infringed. B. F. Goodrich Co. v. United States Rubber Co., D.C.Md., 147 F.Supp. 40. As we are of opinion that he was correct in holding the patent invalid for lack of invention over the prior art, we shall confine our discussion to that point.
