The Verdict & Legal Analysis
Outcome
The Federal Circuit ordered dismissal of the appeals based on the parties’ joint stipulation of voluntary dismissal under FRAP 42(b). Each side bears its own costs. No damages were awarded, no injunction was issued, and no merits ruling was rendered on validity or infringement. The case is closed.
Key Legal Issues
The appeal arose from a patentability-based invalidity or cancellation action. The voluntary dismissal means the underlying patent’s validity status remains unresolved by this court. This outcome preserves SB IP Holdings’ ability to assert the patent in other proceedings, while Vivion avoids a precedential ruling that could have strengthened the patent against future challenges.
