A QUESTION OF PATENT RIGHTS.
[BY TELEGRAPH.—PRESS ASSOCIATION.] Wellington, Friday. In the Supreme Court to-day the Chief Justice, with whom the Hon. E. Richardson was sitting as assessor, gave judgment in a patent case heard last month. The case was one in which an application was made on behalf of Charles Robertson, of New South Wales, for the revision of.the decision of the patent officer in favour of an invention by Charles Campbell, of Otngo. The patent in dispute was for shifting and dredging auriferous gravel, the power used being an admixture of air and water. The Registrar granted a patent to Campbell, and a case was brought in the Supreme Court to set it aside, on the ground that the principle had already been patented by Robertson. The question which the Court was asked to decide was, How far an applicant can copy a patent of a previous invention. The Court held that it was not bound to try the question of infringement now, but left the parties to litigate in a subsequent action. The letters patent were granted at the risk of the applicant (Campbell), and the appeal was dismissed, with £12 12s cost*. .
