Case Brief Summary & Legal Analysis
tl;dr: A state-law legal malpractice claim, even if it requires deciding a federal patent law issue, does not “arise under” federal law. Therefore, federal courts lack exclusive jurisdiction, and the case properly belongs in state court.
Legal Significance: This case clarifies the “substantial federal issue” prong of the Grable test for federal question jurisdiction, holding that the issue must be substantial to the federal system as a whole, not merely to the specific litigants in the case.

Case Facts & Court Holding
Key Facts & Case Background
Respondent Minton sued for patent infringement in federal court, but his patent was declared invalid under the “on-sale” bar. Minton’s attorneys, including petitioner Gunn, had failed to timely raise the “experimental use” exception to that bar. Minton then filed a legal malpractice suit against Gunn in Texas state court. To prove causation under Texas law, Minton had to establish a “case-within-a-case,” meaning he had to show he would have won the original patent suit if his attorneys had raised the experimental-use argument. This required the state court to analyze and apply federal patent law. Minton later argued that because his malpractice claim depended on resolving this federal patent issue, it “arose under” federal patent law, giving federal courts exclusive jurisdiction under 28 U.S.C. § 1338(a) and divesting the state court of jurisdiction. The Texas Supreme Court agreed, holding the embedded federal issue was substantial enough to confer federal jurisdiction. The U.S. Supreme Court granted certiorari to resolve the jurisdictional question.
