    Patent Opposition and the Constitution: Before or After?

    by

    Date: April 2007

    Abstract: “The opposition procedure in Australian patent law is an effective tool for improving the quality of granted patents. The current, pre-grant, process is, however, open to abuse by opponents who merely wish to delay the grant of a patent. Received wisdom has it that a post-grant procedure would be contrary to the Australian Constitution – that is, for a delegate of the Commissioner of Patents to decide an opposition post-grant would be an improper exercise of judicial power. This article details the various tests for judicial power to assess the veracity of this wisdom. The conclusion, after a review of the High Court precedents and commentary, is that a post-grant opposition procedure, assuming it is substantially similar to the current pre-grant process, would not offend the Constitution.”
