This morning the Federal Circuit released two precedential opinions, one nonprecedential opinion, and two nonprecedential dismissals. One of the precedential opinions addresses an appeal from five final written decisions of the Patent Trial and Appeal Board. The other precedential opinion addresses an appeal from a grant of summary judgment of noninfringement in a patent infringement case. The nonprecedential opinion affirms an arbitrator’s decision in a dispute over removal from a role with the United States Marshals Service. Here are the introductions to the opinions and links to the orders.
