Durack, Michael James & ors v Associated Pool Builders Pty Ltd [1983] FCA 384

Durack, Michael James & ors v Associated Pool Builders Pty Ltd [1983] FCA 384

The appeal was dismissed because the evidence raised a serious question to be tried regarding the validity of the petty patent (anticipation/obviousness). The balance of convenience strongly favoured the respondent, who faced greater hardship from threatened legal action, and the appellants were protected by undertakings as to damages. On this basis, the interlocutory injunction restraining threats was properly granted under s.121 of the Patents Act 1952.
