In Virtek Vision Int’l. ULC v. Assembly Guidance Systems, Inc. the Federal Circuit reversed in part the PTAB’s final written decision in an IPR petition filed by Assembly Guidance, on the basis that the petition failed to identify a motivation to combine elements present in the prior art, stating that: “A reason for combining must exist.” Virtek Vision Int’l ULC v. Assembly Guidance Sys., Inc., 97 F.4th 882, 888 (Fed. Cir. 2024).
