This morning, the Federal Circuit released two opinions, one precedential and one nonprecedential, both in patent cases. The precedential opinion comes in an appeal of a post-grant review proceeding and addresses claim construction, written description, enablement, and motions to amend practice and procedure under the Administrative Procedure Act. The nonprecedential opinion comes in an appeal of an inter partes review and addresses claim construction and anticipation. Late yesterday and this morning, the court also released two nonprecedential orders, one denying a petition for a writ of mandamus that would order transfer, and one dismissing an appeal. Here are the introductions to the opinions and order and a link to the dismissal.
