It's a happy day for Aussie pirates: The Hollywood studio behind the film Dallas Buyers Club has abandoned its fight to extract huge sums of cash from alleged copyright infringers.

Dallas Buyers Club LLC had until midday Thursday to lodge a second appeal against an August Federal Court decision which effectively prevented it from engaging in so-called "speculative invoicing" in Australia.

Michael Bradley of Marque Lawyers, who represented the studio in the case, confirmed to Fairfax Media the studio had not appealed the decision by the deadline.

He said while his client was disappointed by the final outcome of the case, it was not the end of the war against piracy in Australia.
