  • Counsel for patentee Celanese in five inter partes review petitions filed by competitor Daicel challenging validity of Celanese patents related to industrial acetic acid production. The Patent Trial and Appeal Board initially ruled in favor of client Celanese, completely denying all five petitions, although requests for rehearing subsequently resulted in the institution of 3 of the 5 IPRs. In June of 2016, the PTAB issued final written decisions in the three IPRs, finding for patent owner Celanese and affirming all instituted claims as not unpatentable.
