This morning the Federal Circuit released a precedential opinion in a patent case appealed from the Northern District of West Virginia. In the opinion, based on a changed claim construction the court vacated a judgment of noninfringement, but the court also affirmed a determination of nonobviousness. Judge Taranto dissented in part based on disagreement with the Federal Circuit’s claim construction. The court also released a nonprecedential opinion in a patent case appealed from the Patent Trial and Appeal Board and another nonprecedential opinion in a pro se case. Here are the introductions to the opinions.
