Dispute Summary
PacifiCorp and its affiliates have petitioned the PTAB to invalidate U.S. Patent 10,926,218, which covers mercury removal from coal‑fired power plant flue gas. The petition alleges anticipation and obviousness over several prior‑art references and argues lack of written‑description support for key claim limitations. The Board has yet to decide whether to institute the IPR.
