The Federal Court today handed down judgment in the matter of ACCC v Pfizer Australia Pty Ltd (Pfizer). Justice Flick also found that the ACCC had failed to establish that Pfizer had pursued its conduct for the proscribed purpose of deterring or preventing competitors from engaging in competitive conduct or for the purpose of substantially lessening competition. The ACCC brought this case because it raised important public interest issues regarding the conduct of a patent holder nearing the expiry of that patent and what constitutes permissible competitive conduct.
