Short Summary
Sarepta has filed an IPR petition challenging Genzyme’s 7,704,721 AAV vector patent, asserting that the claims are obvious over prior‑art purification methods. The petition cites Auricchio, Konz, Potter and related references to support its grounds.
Detailed Summary
Sarepta Therapeutics filed Inter Partes Review Petition IPR2025‑01195 seeking cancellation of claims 1‑4, 6, 7 and 11 of U.S. Patent No. 7,704,721, which covers methods for preventing aggregation of recombinant adeno‑associated virus (rAAV) vectors. The petitioner argues that the claimed methods are obvious in view of the combination of prior‑art references—Auricchio with Konz and Potter with Konz—each teaching the individual steps and parameters recited in the claims. Detailed claim‑by‑claim analysis is provided, showing how each limitation is disclosed in the references, and the petitioner contends that secondary considerations such as commercial success are not sufficiently linked to the claims. The petition requests institution of the IPR and cancellation of the challenged claims.
