Detailed Summary

Inari Agriculture, Inc. petitioned the PTAB for a post‑grant review of Pioneer Hi‑Bred International’s U.S. Patent No. 11,659,803, which claims an inbred maize variety (1PFLQ21). The petition challenges claims 1‑20 on five grounds: three obviousness grounds under 35 U.S.C. §103 based on the Chifflet, Smalley, and Gadlage patents; a lack‑of‑utility ground under 35 U.S.C. §101; and a novel‑question ground under §101 concerning whether plant utility claims must disclose a specific benefit. The petitioner argues that the claimed variety is indistinguishable from prior‑art varieties, provides no specific utility, and that the Board should address the unsettled legal question. No discretionary denial issues are identified, and the petition seeks institution of the review.
