Short Summary
Nicholson Manufacturing has petitioned the PTAB to cancel all 18 claims of BID Group Technologies' AI‑enabled log debarking patent, asserting obviousness, lack of patent‑eligible subject matter, and indefiniteness.
Detailed Summary
In a Post‑Grant Review petition (PGR2025‑00081), Nicholson Manufacturing Ltd., together with Kadant Inc., challenges U.S. Patent No. 12,163,947 owned by BID Group Technologies Ltd. The petitioner seeks cancellation of claims 1‑18 on five grounds: three obviousness arguments under 35 U.S.C. §103 combining the prior‑art references Gagnon, Ido, Kambla, and Petruzella; a §101 abstract‑idea challenge asserting that the claims merely apply generic deep‑learning models to a known debarking process; and a §112(b) indefiniteness challenge to claims 7‑8. The petition is supported by a declaration from Dr. Michael Pazzani and cites extensive case law, including Alice and Recentive Analytics. No institution decision has been made yet.
