strued against him. Reflectolyte Co. v. Luminous Unit Co., 8 Cir., 20 F.2d 607. Plaintiff can not successfully urge that his patent is broad enough to cover silicon carbide as an abrasive. Holland Furniture Co. v. Perkins Glue Co., 277 U.S. 245, 48 S.Ct. 474, 72 L.Ed. 868; General Electric Co. v. Wabash Appliance Co., 304 U.S. 364, 58 S.Ct. 899, 82 L.Ed. 1402; Schriber-Schroth Co. v. Cleveland Trust Co., 305 U.S. 47, 59 S.Ct. 8, 83 L.Ed. 34.
In Holland Furniture Co. v. Perkins Glue Co., supra, the court said [277 U.S. 245, 48 S.Ct. 479, 72 L.Ed. 868]: “But an inventor may not describe a particular starch glue which will perform the function of animal glue and then claim all starch glues which have those functions, or even all starch glues made with- three parts of water and alkali, since starch glues may be made with three parts of water and alkali that do not have those properties. * * That the patentee may not by claiming a patent on the result or function of a machine extend his patent to devices or mechanisms not described in the patent ,is well understood.”
In General Electric Company v. Wabash Appliance Co., supra, the court said [304 U.S. 364, 58 S.Ct. 903, 82 L.Ed. 1402]: “But the vice of a functional claim exists not only when a claim is ‘wholly’ functional, if that is ever true, but also when the inventor is painstaking when he recites what has already been seen, and then uses conveniently functional language at the exact point of novelty.”
The clause describing the abrasive as one which is “in normal use incapable of scratching or impairing the skin” does not designate the abrasive, but only how it is supposed to function. Such a claim may not be invoked to preempt products outside the scope of the disclosure of the patent.
As defendants’ product does not infringe upon the teaching of plaintiff’s patent, we need not concern ourselves as to its validity. .
We have put aside as unnecessary for the decision of this case the fact, of which we may take judicial notice, that the plaintiff has stipulated with the Federal Trades Commission that its commercial product, alleged to conform to its patent, shall not be sold in interstate commerce under representations that its product “does not irritate the skin.”
Confessedly, defendants’ product is not of a character that is “in normal use incapable of scratching or impairing the skin.” Their device is not so clearly in conflict with the teaching of plaintiff’s patent as to warrant a finding of infringement. The novelty obtaining in the device or product described in the patent is not found in defendants’ product.
The decrees appealed from are therefore reversed and the cause remanded with directions to enter decrees dismissing plaintiff’s bills of complaint on their merits. 1
