"On the flip side, these and other recent decision

"On the flip side, these and other recent decisions establish that challengers must do far more than argue that the claimed idea was long known or analogous to some other real-world solution. Indeed, the Federal Circuit stated in Data Engine, “It is not enough . . . to merely trace the invention to some real-world analogy.” Instead, defendants should attack the intrinsic record’s failure to disclose a specific solution to a specific problem. Kaavo, Inc. v. Amazon.com Inc., 323 F. Supp. 3d 630 (D. Del. 2018) provides a successful example of this approach in the District of Delaware, with Chief Judge Leonard P. Stark finding that the specification didn’t “discuss any technological problems in the field nor explain how the claimed invention provides an unconventional technological solution.” But if that argument can’t credibly be advanced, a defendant can still succeed by showing that the claim-at-issue isn’t limited to the disclosed solution. The Federal Circuit in Data Engine found that other claims were ineligible for this very reason."

UH OH OUR ANCIENT GREEK BS AIN'T GONNA BE ENOUGH!
