Appeal from the United States Patent and Trademark Office, Patent Trial and Appeal Board in No. IPR2018- 00063. ______________________

Before CHEN, HUGHES, and STOLL, Circuit Judges. CHEN, Circuit Judge. ORDER Nanya Technology Corporation, Nanya Technology Corporation Delaware, and Nanya Technology Corporation U.S.A. (collectively, Nanya) petitioned for inter partes re- view of claims 1, 3, 4, 11, 13, and 14 of U.S. Patent No. 6,097,061 (the ’061 patent) owned by Lone Star Silicon In- novations, LLC (Lone Star). In its Final Written Decision, Case: 19-2152 Document: 45 Page: 2 Filed: 05/14/2020

the Patent Trial and Appeal Board (Board) held that all the challenged claims are unpatentable under both Nanya’s and Lone Star’s proposed claim constructions for the phrase “a channel region formed in the semiconductor sub- strate.” Nanya Tech. Corp. v. Lone Star Silicon Innova- tions LLC, No. IPR2018-00063 (P.T.A.B. May 15, 2019). Lone Star appeals the Board’s decision. In a decision issued today in an appeal from a separate IPR on the same patent, we affirmed the Board’s decision holding claims 1, 3–6, 11, and 13–16 of the ’061 patent un- patentable. Lone Star Silicon Innovations LLC v. Iancu, No. 19-1556, — F. App’x — (Fed. Cir. May 14, 2020). Thus, this appeal is moot in light of that decision. Cisco Sys., Inc. v. TQ Delta, LLC, 928 F.3d 1359, 1361 (Fed. Cir. 2019).

IT IS ORDERED THAT: Accordingly, this appeal is dismissed as moot in light of our affirmance in Lone Star Silicon Innovations LLC v. Iancu, No. 19-1556, — F. App’x — (Fed. Cir. May 14, 2020), which invalidated all of the claims at issue in this appeal.

Each party shall bear its own costs.
