Short Summary
Inari Agriculture challenges Pioneer’s corn‑seed patent, arguing that the PTAB’s denial of institution improperly rewards secrecy of parent lines. The petitioner seeks Director Review to overturn the decision and prevent a precedent that could undermine disclosure in plant‑breeding patents.
Detailed Summary
Inari Agriculture, Inc. filed a Petition for Director Review after the PTAB denied institution of its PGR challenging Pioneer Hi‑Bred International’s U.S. Patent No. 11,660,020 covering an inbred corn plant. Inari contends that the Board’s decision creates a loophole allowing plant breeders to obtain utility patents by keeping one parent line proprietary, thereby sidestepping obviousness analysis under §103. The petition cites USDA recommendations, prior‑art patents such as the “Smalley” line, and case law to argue that undisclosed parental information is material to patentability and should be disclosed during examination. Inari also raises a novel legal question under §324(b) about whether refusal to provide proprietary information precludes further examination. The Board treated the issue as a policy matter, prompting Inari to seek Director Review to correct what it views as a legal error with significant industry implications.
