In a recent post-grant review decision, the PTAB sided with the patentee and denied institution of a PGR challenge to U.S. Patent No. 11,696,545 (“the ‘545 patent”), which claims an inbred maize variety designated PH4CYJ. Inari Agriculture, Inc. v. Pioneer Hi-Bred International, Inc., PGR2024-00023, Paper 15 (P.T.A.B. Oct. 15, 2024). The case is interesting for several reasons — most notably because it upholds a utility patent covering a plant line developed through simple cross breeding. In my post, I point to two deficiencies in the Board’s decision (1) its lack of reasoning for a determinative claim construction; and (2) its conclusion that a parent-line of maize used in the cross breeding was not prior art because it was not publicly available at the time.
