The court dismissed 7 (5.47%) of the cases 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 a case, 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 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 a case moot.

An important tool that helps the Federal Circuit manage its growing docket of PTAB appeals is the Rule 36 affirmance, whereby the court affirms the PTAB without rendering a full, written opinion. Of the 128 PTAB appeals it has considered thus far, the Federal Circuit has issued Rule 36 affirmances in 69 (53.91%) of cases. The court issued written opinions, including affirmances, reversals, and mixed decisions, in 59 (46.09%) of its cases.
