Berkshire Hathaway Energy Company et al. v.MES, Inc.
Berkshire Hathaway Energy and its affiliates challenge Birchtech's patent on mercury control, arguing the PTAB is the proper forum and that the Director’s review request should be denied. The petitioners contend there are no settled expectations, no time‑bar issues, and no undisclosed parties influencing the case.
Berkshire Hathaway Energy Company et al. v.MES, Inc.
Berkshire Hathaway Energy group petitions the PTAB to institute IPR of U.S. Patent 10,668,430 covering mercury removal methods, arguing obviousness and lack of priority support.
PacifiCorp et al. v.MES, Inc.
PacifiCorp challenges the Director’s referral of its IPR on a mercury‑control patent, arguing the PTAB is the appropriate forum and requesting denial of the Director Review. The response highlights prosecution misstatements, lack of settled expectations, and inefficiencies in the MDL.
PacifiCorp et al. v.MES, Inc.
PacifiCorp successfully challenged 26 claims of Birchtech Corp.'s patent (10926218) related to flue gas desulfurization, leading the PTAB to find a reasonable likelihood of prevailing on at least one claim. The Board concluded that combining prior art references was an obvious application of known techniques in mercury removal technology.
UNION ELECTRIC COMPANY et al. v.MES, Inc.
Union Electric seeks Director Review of the PTAB’s denial to institute an IPR against its mercury‑control patent. The patent owner argues the denial is final, the litigation history does not warrant reversal, and the petitioner’s procedural requests are untimely. The Board is urged to uphold the denial.
UNION ELECTRIC COMPANY et al. v.MES, Inc.
Union Electric seeks Director Review to overturn a discretionary denial and force an IPR on MES’s mercury‑control patent. The petition argues the patent is invalid in view of extensive prior art and prior Board findings. Settlement activity by the patent owner raises concerns of avoiding a merits decision.
PacifiCorp et al. v.MES, Inc.
PacifiCorp and affiliated utilities have filed an IPR petition seeking to invalidate MES’s 10,589,225 patent covering mercury‑removal methods in coal‑fired power plants.

PacifiCorp et al. v.MES, Inc.
PacifiCorp and its affiliates have filed a petition to institute an IPR against MES’s 10,933,370 patent covering mercury‑removal methods, arguing the claims are obvious over multiple prior‑art references and that the claimed additive‑to‑sorbent ratio lacks patentable weight.
