Heading: The Alleged Infringement.

Text: The infringement relied upon is what is called contributory infringement. It is claimed by plaintiff that defendant has furnished to the trade kits of materials similar to those furnished by plaintiff, and has instructed the purchasers how to use those materials in applying a rubber patch to the inner tube of an automobile tire; that those instructions given by defendant are followed by the purchasers, and in so doing they infringe the process patent of plaintiff. The materials furnished by plaintiff to the trade for carrying out the patented process are not patented, and plaintiff makes no claim of infringement against defendant for furnishing such similar materials to purchasers. The alleged infringement of defendant consists solely in procuring others to infringe plaintiff's patented process; and this is done by instructions or directions to his customers. The instructions or directions complained of are to be found on the containers of the patching materials. The first set of directions used was as follows: No Cement USE No Heat No Gasoline
