Federal Circuit Finds Regeneron Transgenic Mouse Patent Invalid For Inequitable Conduct With Intent Inferred From Litigation Misconduct

In a 38 page decision with a 19 page dissent by Judge Newman, the Federal Circuit determined that Regeneron’s transgenic mouse patent is unenforceable due to inequitable conduct. The decision was rendered in Regeneron Pharmaceuticals v. Merus N.V., where the requisite intent to deceive was inferred as a sanction for Regeneron’s “widespread litigation misconduct.” Chief Judge Prost and Judge Wallach agreed such a sanction was permissible, while Judge Newman urged otherwise.

Coherus Challenges One AbbVie Humira Patent In Four PTAB Proceedings

Does Amgen Have Viable State Law Claims Against Sandoz Arising From The Zarxio Biosimilar Patent Dispute?

In Sandoz Inc. v. Amgen Inc. (which you can read more about here), the Supreme Court held that 42 USC § 262(l)(9)(C) sets forth the exclusive federal remedy for failing to provide a copy of the biosimilar application to the reference product sponsor. Still, the Court directed the Federal Circuit to revisit Amgen’s state law claims to determine whether such conduct is “unlawful” under California’s unfair competition laws and/or whether the Biologics Price Competition and Innovation Act (BPCIA) preempts any remedies available under state law. Here, we consider how the Federal Circuit may address these issues.
