Courtaulds Ltd's Patent, Re [1952] HCA 53

Courtaulds Ltd's Patent, Re [1952] HCA 53

The applicant could not rely on its own alleged pre-acquisition business loss because it was not then the patentee or beneficially interested in the patent, and s. 84 (6) concerns loss suffered by the patentee as such. However, International Rayon Corporation, while patentee, was for at least four years prevented by specified hostilities from selling or otherwise exploiting its Australian patent, causing compensable delay, and the applicant as assignee could rely on that loss. The applicant also proved at least one further year of delay after 1945 caused directly by hostilities. The patent term was therefore extended for five years from 17th November 1952.

Procedural Posture

Originating Summons Under S. 84 (6) of the Patents Act 1903 1950 for Extension of the Term of Letters Patent / Written Judgment on Application

Legal Issues

  1. 1 ['Whether an assignee patentee can rely under s. 84 (6) on alleged business loss suffered before it became patentee or had a beneficial interest in the patent.' 'Whether International Rayon Corporation, the predecessor in title, suffered loss or damage as patentee by being prevented during hostilities from selling or otherwise exploiting the Australian patent.' 'Whether an assignee may found an application for extension on loss or damage sustained by the original patentee or predecessor in title.' 'Whether post-1945 circumstances arising directly out of hostilities delayed the applicant in establishing its undertaking in Australia and justified an additional extension.' 'What period of extension should be granted.']
