Amgen’s suit against Apotex

Aug 7, 2018

Amgen files third suit against Apotex based on aBLAs for biosimilars of Neupogen® (filgrastim) and Neulasta® (pegfilgrastim).  The patent under scrutiny, US Patent No. 9,856,287 was issued on 2 January this year and therefore was not included in earlier ‘patent dances’ claiming priority to the original ‘138 patent.  With three additional pending patent applications claiming priority to the ‘138 patent, it is likely that further litigation will result.
