Detailed Summary
In Petition IPR2025‑01199, Arla Foods amba challenges U.S. Patent No. 11,825,860, which claims methods for making denatured whey protein compositions with specific protein, GMP, and particle‑size parameters. The petitioner alleges that the claims are anticipated by Nielsen785 (which incorporates Bertelsen) and obvious in view of combinations of Bertelsen, Nielsen785, Nielsen450, Ozturk, Kawasaki, and LeanCreme. Arla also seeks a claim construction defining “native GMP” as “non‑hydrolyzed GMP.” The petition requests cancellation of claims 8‑9, 11‑13, and 15‑20 under §§102 and 103.
