Dispute Summary
Berkshire Hathaway Energy and affiliated utilities have filed an IPR petition challenging U.S. Patent 10,343,114, which covers a mercury‑removal method for coal‑fired power plants. The petition argues the claims are obvious over earlier conference papers and patents, and that the patent lacks priority support for its bromine‑related limitations.
