Detailed Summary

Inari Agriculture challenged 20 claims covering maize varieties based on obviousness (§103), lack of utility (§101), written description (§112(a)), and enablement (§112(a)). The Patent Owner, Pioneer Hi-Bred International, defended the patent by emphasizing that the claims are directed to a specific genotype (PH4CYJ) not fully addressed by the Petitioner's phenotypic challenges. The Board ultimately denied institution, concluding that Inari failed to meet the likelihood standard for unpatentability because it did not adequately provide evidence regarding PH4CYJ’s unique genetic makeup and its derivation from specific parental lines. Furthermore, the Board rejected the statutory grounds of §101, §112(a) (written description/enablement), finding the patent disclosed specific uses and provided sufficient detail.
