Commenting on the ruling, BeiGene General Counsel Chan Lee said: “We are pleased that the USPTO invalidated all challenged claims of the ‘803 patent. Today’s decision reinforces our belief that Pharmacyclics’ ‘803 patent is overly broad and invalid. BeiGene is confident in the strength of our intellectual property supporting BRUKINSA, a clearly differentiated and independently developed medicine. With approvals in more than 70 countries and regions for the treatment of multiple B-cell malignancies, BRUKINSA continues to set a new standard of care for patients worldwide.”
