Damages were claimed for patent infringement, and met by conditional cross claims for revocation if infringement was found. The claim related to methods of lubricating petrol engines. An expert witness’s evidence was rejected as unreliable or biased.
Held: The evidence suggested that the amendment proposed was to be allowed, that the patent did disclose a new step, and was valid, and not infringing of any other patent.
