Summary
The Supreme Court held that 28 U.S.C. § 1338(a) does not deprive state courts of subject-matter jurisdiction over a state-law legal malpractice claim arising from patent litigation. Although resolving the malpractice claim required deciding a disputed patent-law issue, that issue was not sufficiently substantial to the federal system, and state-court adjudication would not disrupt the federal-state balance. The Court reversed and remanded the judgment of the Supreme Court of Texas.
Questions Presented
- Whether 28 U.S.C. § 1338(a) gives federal courts exclusive jurisdiction over a state-law legal malpractice claim whose resolution requires deciding a hypothetical federal patent issue.
- Whether Minton's malpractice claim satisfies the four-part Grable test for federal arising-under jurisdiction.
Holdings
- Section 1338(a) does not deprive state courts of subject-matter jurisdiction over a state-law legal malpractice claim merely because resolving the claim requires determination of a hypothetical patent-law issue.
- Minton's malpractice claim necessarily raised an actually disputed federal patent issue because causation required a case-within-a-case determination of whether a timely experimental-use argument would have changed the outcome of the prior patent litigation.

Factual background
Minton developed a computer program and telecommunications network for securities trading and leased the system to a brokerage more than one year before applying for a patent based substantially on the system. In Minton's subsequent federal patent infringement action, the district court invalidated the patent under the on-sale bar. Minton's attorneys did not timely raise an experimental-use argument, and Minton later alleged that this omission caused the loss of his patent case. The Texas trial court rejected the malpractice claim on summary judgment, finding less than a scintilla of proof that the lease was experimental.
Procedural history
Minton's patent infringement action in federal district court resulted in summary judgment declaring his patent invalid under the on-sale bar. The Federal Circuit affirmed the denial of Minton's motion for reconsideration, which raised an experimental-use argument for the first time. Minton then sued his attorneys for malpractice in Texas state court. The trial court granted summary judgment to the attorneys, and the Texas Court of Appeals affirmed on the merits and rejected Minton's jurisdictional argument. The Texas Supreme Court reversed, concluding that exclusive federal patent jurisdiction applied. The United States Supreme Court reversed and remanded.
Remand instructions
Remanded to the Supreme Court of Texas for further proceedings not inconsistent with the opinion.
