Neff Instrument Corporation v. Cohu

This is an appeal and a cross-appeal from an action brought in the United States District Court by plaintiff for infringement of United States Letters Patent No. 2,832,848 by defendant. In a prior appeal this court reversed the entry of a summary judgment by the district court. After a supplemental complaint had been filed and answered, the case was tried and the district court entered a judgment holding the patent valid but not infringed. No issues here involved were present in the prior appeal. Plaintiff appeals from the district courts holding that the patent was not infringed. Defendant appeals from the district courts holding that the patent was valid in law.
