Patent Litigation

  • Since the U.S. Supreme Court decided Mayo and Myriad, the Federal Circuit has expanded the holdings and invalidated more patents directed to biological discoveries.

  • Beginning on Nov. 13, 2018, the USPTO will cease to apply the broadest reasonable interpretation (BRI) standard for newly-filed IPR, PGR, and CBM trials under the America Invents Act (AIA).
