Short Summary
The PTAB denied Pharaoh Energy Services' petition to institute IPR proceedings against Flex-Chem for patent 9944843, citing a lack of compelling merits. The Board found that the cumulative weight of Fintiv factors and insufficient technical basis in the petitioner’s evidence led to the denial.
Detailed Summary
The Patent Trial and Appeal Board denied Pharaoh Energy Services' petition to institute IPR proceedings against Flex-Chem Holding Company and Flex-Chem Services Corporation regarding patent 9944843. Although the petitioner asserted grounds of anticipation (102) and obviousness (103) over prior art references Frenier and Reyes, the Board determined that the merits were not compelling enough to warrant institution under 35 U.S.C. § 314(a). The decision heavily relied on an analysis of the Fintiv factors, where the proximity of trial date and overlap with parallel district court litigation strongly favored denial. Furthermore, the Board found Petitioner's reliance on expert declarations was inadequate because they lacked technical depth regarding key limitations like 'nano-darcy shale formation.'
Practitioner Note
