This decision related to a motion brought by the Defendant, uniQure BioPharma B.V., where the main action (the “Action”), brought by Pfizer Canada ULC and Pfizer Inc. (collectively, “Pfizer”), was to impeach uniQure’s Canadian Patent No. 2,737,094. The motion was for a stay of the proceeding on the basis that the 094 Patent was being re-examined at uniQure’s request, and in that process the scope of the claims and the issues in the proceeding may be narrowed.
