Patent counterclaims and appeals
Holmes Group v. Vornado Air Circulation Systems
In brief
A patent counterclaim alone could not give the Federal Circuit authority to hear this appeal; the Court wiped out its ruling and sent the case back.
- Where it stands
- Decided
Decided 9-0 · June 3, 2002 · Opinion by Justice Scalia
- What it’s about
- The Supreme Court ruled that the Court of Appeals for the Federal Circuit lacks jurisdiction over a case where the only patent law issues appear in a defendant's counterclaim rather than the plaintiff's original complaint.
- Who it affects
- The Federal Circuit cannot hear an appeal when the complaint alleges no patent claim and patent law appears only in the defendant's counterclaim.
Summary: written with AI from the case record.
What it's about
The decision reinforced the "well-pleaded complaint rule," establishing that federal patent jurisdiction depends solely on the claims asserted by the plaintiff.
The dispute turned on whether the plaintiff's original complaint or the defendant's later counterclaim determined which appeals court could hear the case.
Question presented
Does the Court of Appeals for the Federal Circuit have appellate jurisdiction over a case in which the complaint does not allege a claim arising under federal patent law, but the answer contains a patent-law counterclaim?
What the Court decided
Holding
The Federal Circuit cannot assert jurisdiction over a case in which the complaint does not allege a patent-law claim, but the answer contains a patent-law counterclaim. 961, vacated and remanded.
- Result
- Vacated
The Court's reasoning
The Court said the Federal Circuit's power to hear the appeal depends on whether the plaintiff's complaint raises a patent claim; a patent counterclaim in the answer is not enough.
