Score another win for pharma against investment funds-turned-IPR petitioners. On September 21, 2015, the PTAB denied institution of Ferrum Ferro Capital, LLC’s (“FFC”) petition for IPR of an Allergan patent claim related to its Combigan® eye-drop product for treating glaucoma. This dispute has attracted publicity for having bled into the courts, where Allergan has sued FFC for extortion, unfair competition, and malicious prosecution. The PTAB’s non-appealable denial of FFC’s petition is obviously a significant victory for Allergan, and follows the PTAB’s recent denials of two IPR petitions filed by the Coalition For Affordable Drugs.
