A couple weeks ago the Federal Circuit issued a short opinion in Hantz Software, LLC v. Sage Intacct, Inc., No. 2022-1390, 2023 WL 2569956 (Fed. Cir. Mar. 20, 2023) that I suspect may have an outsized affect on 101 practice in Delaware.
The complaint in Hantz, alleged that the defendant infringed "one or more" claims of the asserted patents and attached claim charts for 8 particular claims. Defendant filed a 12(b)(6) motion on 101 grounds which the court granted, finding all of the claims of the asserted patents unpatentable. Plaintiff appealed the ruling to the extent it invalidated claims other than those specifically charted in the complaint.
The Federal Circuit vacated judgment on the other claims, stating:
[W]e agree that the operative complaint asserted infringement of only claims 1 and 31–33 of each asserted patent, and because Sage did not file any counterclaim of its own (instead, it simply moved to dismiss Hantz’s complaint), we conclude that the ineligibility judgment should apply to only claims 1 and 31–33 of the asserted patents.
