SAN CARLOS, Calif., April 29, 2025--(BUSINESS WIRE)--BeiGene, Ltd. (NASDAQ: ONC; HKEX: 06160; SSE: 688235), a global oncology company that intends to change its name to BeOne Medicines Ltd., today announced that the U.S. Patent and Trademark Office (USPTO) rendered a Final Written Decision invalidating all claims of Pharmacyclics LLC’s (Pharmacyclics) U.S. Patent No. 11,672,803 (the ‘803 patent) that were challenged by BeiGene in a post-grant review (PGR) proceeding.
On November 1, 2023, BeiGene filed a PGR petition with the USPTO challenging the validity of certain claims of the ‘803 patent, in response to a patent infringement lawsuit Pharmacyclics brought against BeiGene concerning BRUKINSA® (zanubrutinib). On May 1, 2024, the USPTO granted BeiGene’s petition to institute the PGR. The USPTO’s Final Written Decision is appealable by Pharmacyclics.
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."
About BRUKINSA® (zanubrutinib)
BRUKINSA is an orally available, small molecule inhibitor of Bruton’s tyrosine kinase (BTK) designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared with other approved BTK inhibitors, BRUKINSA has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease-relevant tissues.
BRUKINSA has the broadest label globally of any BTK inhibitor and is the only BTK inhibitor to provide the flexibility of once or twice daily dosing. The global BRUKINSA clinical development program includes about 7,100 patients enrolled in 30 countries and regions across more than 35 trials. BRUKINSA is approved in more than 70 markets, and more than 180,000 patients have been treated globally.
