Keasbey & Mattison Co. v. H. W. Johns-Manville Co.

The same questions involved here, substantially, have recently been passed upon by the Circuit Court of Appeals, Third Circuit, in Keasbey & Mattison Co. v. American Magnesia & Covering Co., 143 Fed. 490. It is only necessary for this court to refer to the opinion of that court in that case. The views there expressed are adopted.

There will be a decree accordingly and for an accounting. The patent is valid. Keasbey was the inventor, and defendant infringes.
