This morning the Federal Circuit released one precedential opinion, four nonprecedential opinions, two nonprecedential orders, and an erratum. The lone nonprecedential opinion comes in a patent case on appeal from the Patent Trial and Appeal Board. Of the nonprecedential opinions, all four also come in patent cases on appeal from the Patent Trial and Appeal Board. Of the nonprecedential orders, one denies a petition for writ of mandamus and one dismisses an appeal. Here are the introductions to the opinions and the order denying the petition for a writ of mandamus, as well as links to dismissal and erratum.
