Federal Circuit Argues Over IPR Appeal Procedure
On March 23, 2018, a divided panel of the United States Court of Appeals for the Federal Circuit (CAFC) found that the Patent Trial and Appeal Board (PTAB) had not sufficiently explained its reasoning in a final written decision invalidating certain patent claims, and reversed the invalidity ruling. DSS Tech. Mgmt. v. Apple Inc., appeal nos. 2016-2523 and 2016-2524. One member of the panel (Newman, J.) dissented, both on the merits, and on whether the panel should have ordered remand instead of reversing.
