Dispute Summary
PacifiCorp and co‑petitioners have filed an IPR petition challenging U.S. Patent 10,926,218, which covers mercury‑removal methods for coal‑fired power plants. They contend the claims are obvious over a combination of four prior‑art references and that the claimed additive ratio lacks patentable weight.
