This morning, the Federal Circuit issued a precedential opinion in a patent case, finding that the Patent Trial and Appeal Board erred by invalidating a claim for anticipation when the relevant petition asserted only obviousness. The court also issued a nonprecedential opinion in another patent case affirming PTAB findings of obviousness. Finally, the court issued two Rule 36 judgments. Here are the introductions to the opinions and links to the Rule 36 judgments.
