This morning the Federal Circuit issued three precedential opinions. The first two come in related patent cases appealed from the Eastern District of Texas and address claim construction, infringement, and definiteness. The third comes in another patent case appealed from the District of Columbia and replaces an earlier opinion, issued by the Federal Circuit in August, regarding the shifting of attorney and expert witness fees in civil actions to obtain patents. The Federal Circuit also issued two nonprecedential opinions appealed respectively from the Court of Appeals for Veterans Claims and the Trademark Trial and Appeal Board. Finally, the Federal Circuit issued four Rule 36 judgments. Here are the introductions to the opinions and links to the Rule 36 judgments.
