This morning, the Federal Circuit released three nonprecedential opinions and one nonprecedential order. One opinion addresses an argument that the Patent Trial and Appeal Board adopted erroneous constructions of claim terms. Another opinion addresses an appeal from a summary judgment holding claims invalid for lack of eligibility. The final opinion, also from a patent case, addresses the enforceability of an arbitration agreement and a finding of indefiniteness. The nonprecedential order grants a voluntary dismissal. Here are the introductions to the opinions and a link to the dismissal.
