Firth Industries Ltd v Polyglas Engineering Pty Ltd [1975] HCA 25

Firth Industries Ltd v Polyglas Engineering Pty Ltd [1975] HCA 25

The interlocutory injunction was refused because the defendants raised substantial issues as to the validity of the patent, the patent was not an old patent of long standing and no special circumstances justified departing from the general practice approved in Beecham. In any event, the evidence did not establish infringement of the method claims, and the defendants gave undertakings to pay ultimately recoverable damages and to keep accounts of compost bin sales and proceeds.
