Canadian Solar, Inc. v. Maxeon Solar Pte. Ltd.
Patent Trial and Appeal Board
Holding
The Federal Circuit dismissed the appeal as moot because Maxeon’s unilateral covenant not to sue eliminated the live controversy. Because mootness resulted from the unilateral action of the party that prevailed before the Board, the court vacated the final written decision as to claim 12.
Why It Matters
A patent owner’s post-Board covenant not to sue can moot an IPR appeal, but if the patent owner prevailed below, the Federal Circuit may vacate the adverse-to-petitioner Board ruling rather than leave it intact.
