Headnotes

  1. Federal Courts & Jurisdiction — Exclusive Jurisdiction over Patent Cases The federal courts have exclusive jurisdiction of all cases arising under the patent laws, but not of all questions in which a patent may be the subject-matter of the controversy. 223 U.S. at 478
  2. Federal Courts & Jurisdiction — State Jurisdiction over Patent Questions State courts may try questions of title to patents and may construe and enforce contracts relating to patents. 223 U.S. at 478
  3. Remedies — Specific Performance A suit to compel the assignment of a patent, on the ground that the patent is an improvement on an earlier one and is included in a covenant to convey all such improvements, is based on general principles of equity jurisprudence and does not present a case arising under the patent law; the state court has jurisdiction to determine ownership and to enter a decree requiring the patentee and a subsequent assignee holding with notice to make an assignment in due form. 223 U.S. at 478–479
  4. Remedies — State Court Jurisdiction Where an injunction restraining the manufacture and sale of articles covered by a patent is only an incident to a decree for specific performance of a contract to convey the patent as an improvement of an earlier one, and the bill does not involve any construction of the patent or charge infringement, the relief is appropriate and is within the jurisdiction of the state courts. 223 U.S. at 479–480
