Dispute Summary
Apotex petitions the PTAB to review US 7,919,499, covering a long‑acting naltrexone formulation, asserting that the claims are anticipated or obvious over Comer, Nuwayser, Rubio and Wright. The petition cites a prior IPR that was instituted and later terminated, and argues that discretionary denial is unwarranted.
