Summary:
This case arose out of a claim for the infringement of a patent. The plaintiff claimed that the defendant infringed his patent with respect to a machine for obtaining uniform tension in electrical cable installations. The Trial Division of the Federal Court of Canada dismissed the plaintiff's action and declared the plaintiff's patent invalid. The judgment of the Trial Division is not reported in the series of reports.
On appeal to the Federal Court of Appeal the appeal was dismissed and the judgment of the Trial Division was affirmed. The Federal Court of Appeal referred to the plaintiff's specifications and claims and held that the plaintiff's claims claimed more than he invented and accordingly the patent was invalid.
