Martin Engineering Company & Anor v Trison Holdings Pty Ltd & Anor [1988] FCA 377

Martin Engineering Company & Anor v Trison Holdings Pty Ltd & Anor [1988] FCA 377

There is a serious question to be tried on infringement of Claim 1 of Patent No. 512902 by manufacture and sale of the Dyna-Trac system, and on invalidity grounds. The strength of the applicants' case on infringement outweighs the respondents' case for invalidity. The balance of convenience favours granting interlocutory injunctive relief restraining the making and selling of the Dyna-Trac system, excluding sale of spare parts depicted in Exhibits Q and R for existing systems.
