Ryall's Patent, Re [1949] HCA 14

Ryall's Patent, Re [1949] HCA 14

The evidence established that the patentees suffered loss and damage by reason of the recent hostilities because commercial exploitation had not begun before the war, relevant development and manufacturing capacity was diverted to war work, and exploitation was prevented during the war. A substantial extension was justified, covering the period from 3rd September 1939 to the end of hostilities in August 1945 and a further period for transition from war to peace manufacture, making seven years an appropriate term. Because the patents had expired, the extension was to be by re-grant subject to protective conditions.
