Dispute Summary
Topsoe petitions the PTAB to invalidate claims 1‑11 and 17‑19 of Casale’s ’168 patent covering ammonia synthesis from natural gas. The petition relies on anticipation and obviousness arguments using five prior‑art references. The Board has yet to decide whether to institute the review.
