The Verdict & Legal Analysis
Outcome
The Federal Circuit dismissed the appeal pursuant to Rule 42(b)(2) of the Federal Rules of Appellate Procedure, following mutual motions from both parties. The court’s order explicitly stated: “Each side shall bear its own costs.” No damages were awarded, and no injunctive relief was granted or denied on the merits, indicating a negotiated resolution.
Key Legal Issues
The verdict cause was patentability, with the underlying action classified as an invalidity/cancellation action related to U.S. Patent No. 8,072,968 B2. The mutual nature of the dismissal means the patent’s validity remains formally intact at the appellate level, and no new precedential ruling on session management technology patentability was issued by the Federal Circuit.

The dispute involved U.S. Patent No. 8,072,968 B2, covering a “Method and apparatus for supporting multiple active sessions on a per user basis”.
Both parties filed motions — IBM to withdraw and Ebates to voluntarily dismiss — which the court granted under Rule 42(b)(2). Each side bore its own costs, suggesting a negotiated resolution.
Because the court issued no merits ruling, there is no new precedent. However, the case highlights ongoing validity challenges facing software method patents and the strategic value of early appellate resolution.
