A decision by the Supreme Court over the assignor estoppel doctrine could have far-reaching implications for patent law, argue Jeffrey D Morton, Zachary Schroeder and Ryan D Ricks of Snell & Wilmer.

On January 8, 2021, the US Supreme Court agreed to hear Minerva Surgical v Hologic to consider whether an inventor or those in privity with the inventor may assert patent invalidity as a defence against a patent infringement suit for the inventor’s patent.

The doctrine at issue is known as “assignor estoppel” and provides protection to assignees in patent transactions.
