The Federal Circuit's nonprecedential decision in NimbeLink Corp. v. Digi International Inc., No. 2024-2292 (Fed. Cir. Feb. 23, 2026) has a split decision:
- Reversed a finding that the patent claims were invalid as indefinite;
- Affirmed the dismissal of NimbeLink's breach-of-contract claims arising from two non-disclosure agreements.
The patent issue turned on a familiar question: whether the claim preamble adds a substantive limitation.
