This morning the Federal Circuit issued a precedential opinion in a patent case appealed from the Western District of Texas. The opinion reversed a finding of invalidity. The court also issued four nonprecedential opinions in patent cases appealed from the Patent Trial and Appeal Board. Notably, in the fourth case, Judge Prost wrote a concurring opinion to explain that had a patentability challenge been preserved it likely would have succeeded. Finally, the court issued three nonprecedential orders concerning, respectively, a dismissal for failure to prosecute and two voluntary dismissals. Here are the introductions to the opinions and orders.
