This morning the Federal Circuit released related precedential and nonprecedential opinions addressing parallel appeals from judgments of a district court and the Patent Trial and Appeal Board related to the same patents. In the precedential opinion, the Federal Circuit vacates a district court’s judgment of willful infringement and remands with instructions to dismiss the case as moot given the Federal Circuit’s holding in the related nonprecedential opinion affirming final written decisions of the Patent Trial and Appeal Board finding all of the asserted claims invalid. The Federal Circuit also released another precedential opinion reversing a district court’s finding of lack of personal jurisdiction in another patent infringement dispute. Finally, the Federal Circuit released a second nonprecedential opinion, this one in a separate appeal from another final written decision of the Patent Trial and Appeal Board in an inter partes review proceeding. Here are the introductions to the opinions.
