In a recent decision, Flatwork Technologies LLC v Brierley (2020 FC 997), the Federal Court granted summary judgment in favour of the Plaintiff, Flatwork Technologies, LLC ( Flatwork), in respect of its patent impeachment action. A motion for summary judgment is a streamlined and expeditious procedure whereby a party seeks to have the Court adjudicate some or all of the issues in an action based entirely on a paper record. Unlike a full trial which requires the parties to put forward live witnesses, in a motion for summary judgment all of the evidence is submitted by way of affidavits followed by cross-examinations on those affidavits. A motion for summary judgment may be brought at any time after the defendant has filed a defence but before the time and place for trial have been fixed.
