With a focus on patent litigation, he represents clients in a broad range of sectors with a focus on the pharmaceutical, oil and gas, and telecommunication sectors. He appears frequently in the Federal Court and Federal Court of Appeal, primarily in patent disputes.

As Co-Lead of McCarthy Tétrault’s Oil and Gas Patent Litigation practice, Steven has led successful and significant oil and gas patent litigation mandates.  A selection of Steven’s recent mandates in this sector includes:

  • MEG Energy: This patent infringement action involved a patent that allegedly claimed an improved method of practicing SAGD to recover bitumen from oil sands. The Plaintiffs claimed over a billion dollars in the action and sought an injunction. Steven helped lead MEG Energy’s defence, which resulted in the Federal Court invalidating every asserted claim and issue a declaration that MEG Energy had not infringed any asserted claims. Steven helped lead MEG Energy’s appeal which resulted in a complete dismissal and costs to MEG Energy in excess of half a million dollars [2021 FC 10 and 2022 FCA 118]
  • Aux Sable: This patent impeachment action involved a patent that allegedly claimed an improved method of transporting natural gas by pipeline. Steven helped lead Aux Sable’s claim and obtained an order invalidating the key claims of JL Energy’s patent [2019 FC 581] 
  • Enbridge: The Plaintiff brought an action for patent infringement and various other forms of relief relating to monitoring systems. Steven successfully led Enbridge’s defence, which resulted in the action being struck before Enbridge was required to plead in response [2019 FC 504] 

Steven also led patent infringement mandates relating to proppant technology for Preferred Sands (T-668-17), environmental waste cleanup for Clean Harbors (T-568-15), efficient heaters for Astro Thermal Tec (T-135-18) and downhole tools for Pulse Directional Technologies (T-1668-13).

Additionally, Steven has led or helped lead numerous actions and applications for innovative pharmaceutical companies. A selection of Steven’s mandates in this sector includes:

  • Allergan: This patent infringement action involved patents to crystal forms and formulations containing the medicine silodosin (RAPAFLO®) for the treatment of BPH. Steven helped lead Allergan’s action which resulted in the Federal Court upholding the validity of Allergan’s 002 Patent [2020 FC 1189]
  • Sunovion: Steven helped lead patent infringement actions against Pharmascience [T-315-20], JAMP [T-891-20] and Taro [T-671-20] relating to multiple patents to Sunovion’s drug LATUDA®, which treats schizophrenia and bipolar disorder.
