May v Higgins

This case concerned an appeal to the High Court of Australia from a decision of the Commissioner of Patents. The appeal was brought by John May, the opponent, against Matthew John Higgins, the applicant for a patent for an "improved starting device for distance handicap races." May had opposed the grant of the patent on several grounds, including that the invention had been obtained from him, was previously patented, lacked novelty, and had been described in prior publications. The Commissioner had dismissed May's opposition and granted the patent, leading to this appeal.

The central legal issue before the High Court was whether Higgins was entitled to a patent for the entire combination of his improved starting device. Specifically, the court had to determine if an improvement to a single component of an existing combination, which did not render the combination substantially a new thing, could form the basis of a patent for the entire combination. The court also considered whether such an improvement, if novel and meritorious, could be patented separately.

The High Court, in allowing the appeal, reasoned that the applicant's device, while potentially containing a novel and valuable improvement in the means of releasing the tensional barriers, did not constitute a substantially new combination. The court found that the core of the invention was an alteration to one integer of an old machine, rather than the creation of a new integer or a combination that resulted in a fundamentally different machine. Applying established patent law principles, the court held that an inventor is entitled to a patent for an improvement to a component, but not for the entire combination if the combination itself is not substantially new.

Consequently, the High Court reversed the Commissioner's decision. It declared that the patent grant should not be made unless Higgins sought leave to amend his specification within four months to claim only the improved element. The time for sealing the patent was extended accordingly, and Higgins was ordered to pay the costs of the opposition and the appeal.
