This morning the Federal Circuit released a precedential opinion in a patent case appealed from the Western District of Texas. In the opinion, the Federal Circuit explains why it affirms a judgment of invalidity for indefiniteness. The court also released two nonprecedential opinions, one in a patent case appealed from the Patent Trial and Appeal Board and one in a patent case appealed from the Northern District of California. In the case appealed from the Northern District of California, the Federal Circuit affirms a judgment of invalidity for lack of eligibility. The court also released a nonprecedential order dismissing an appeal. Here are the introductions to the opinions and a link to the dismissal.
