Palmer v Dunlop Perdriau Rubber Company Limited [1937] HCA 43

Palmer v Dunlop Perdriau Rubber Company Limited [1937] HCA 43

The High Court was equally divided. Latham C.J. and McTiernan J. held that the patent claim 1 was sufficiently clear, not excessively broad, and disclosed patentable subject matter by combining known elements in a way that produced a substantially new result (a machine-made vulcanized battery box); they would have found infringement. Rich and Dixon JJ. dissented, holding claim 1 was too wide and indefinite (functional and covering all means), such that it was invalid for want of subject matter; even if confined, the defendant’s machine would not infringe. By virtue of the equal division, the lower court's decision dismissing the suit was affirmed.

Ratio Decidendi

The High Court was equally divided. Latham C.J. and McTiernan J. held that the patent claim 1 was sufficiently clear, not excessively broad, and disclosed patentable subject matter by combining known elements in a way that produced a substantially new result (a machine-made vulcanized battery box); they would have found infringement. Rich and Dixon JJ. dissented, holding claim 1 was too wide and indefinite (functional and covering all means), such that it was invalid for want of subject matter; even if confined, the defendant’s machine would not infringe. By virtue of the equal division, the lower court's decision dismissing the suit was affirmed.
