Dispute Summary
Air Products’ IPR petition against Evonik’s 10,471,380 B2 membrane‑gas‑separation patent is met with a detailed preliminary response. Evonik argues the petitioner has not shown a reasonable likelihood of unpatentability, misinterprets the claims, and that the cited references teach away. The Owner seeks denial of institution.
