On September 16, 2020, the Patent Trial and Appeal Board (PTAB) denied institution of Mylan Labs Ltd.’s petition for IPR of U.S. Patent No. 9,439,906 (“the ’906 patent”) in IPR2020-00440. In doing so, the PTAB exercised discretion to deny institution based on the six factors set forth in its precedential order in Apple Inc. v Fintiv Inc. For Hatch-Waxman Defendants interested in challenging the validity of Orange Book-listed patents at the PTAB, IPR petitions should be filed as early as possible in order to avoid this same result.
