The court dismissed 10 (4.46%) appeals without rendering a decision on the merits. Dismissals may occur, for example, where the Federal Circuit determines that it does not have jurisdiction to hear an appeal, such as in an appeal from a PTAB institution decision. As the Supreme Court established in Cuozzo Speed Techs., LLC v. Lee, the Federal Circuit is barred from considering appeals from at least certain aspects of institution decisions under 35 U.S.C. § 314(d). Dismissals may also result from settlements among the parties to the appeal, or where the court determines that a prior decision renders an appeal moot.

Of the 224 PTAB appeals it has considered thus far, the Federal Circuit has issued Rule 36 affirmances in 110 (49.11%) cases. The court issued written opinions, including affirmances, reversals, dismissals, and mixed decisions, in 114 (50.89%) cases.
