Headnotes

  1. Civil Procedure — Binding Effect of Final Judgment Rights between litigants once established by the final judgment of a court of competent jurisdiction must be recognized in every way, and wherever the judgment is entitled to respect, by those who are bound by it. A judgment that a manufacturer's product does not infringe a patent conclusively determines, as between the patent owner and the manufacturer, the manufacturer's right to make, use, and sell the product free from interference by the patent owner under that patent, and the patent owner's corresponding duty to recognize and yield to that right. 206 U.S. at 289
  2. Patent Law — Infringement A patent owner who has lost a final judgment of non-infringement against a manufacturer violates the manufacturer's rights established by that judgment by bringing infringement suits against the manufacturer's customers for their use or sale of the same product, and a court of equity may restrain the patent owner from prosecuting such suits. 206 U.S. at 289-290
  3. Remedies — Inadequacy of Legal Remedy Where a patent owner's suits against a manufacturer's customers tend to diminish the manufacturer's sales and impose upon him the expense of defending numerous suits to maintain a right already established by judgment, and the extent of the resulting damage would be difficult to prove in an action at law, the legal remedy is inadequate and equity jurisdiction exists to restrain the prosecution of such suits. 206 U.S. at 290
  4. Remedies — Assumption of Defense as Bar A manufacturer's interposition for the defense in a suit brought by a patent owner against one of the manufacturer's customers does not bar the manufacturer from seeking equitable relief against the patent owner for interference with the manufacturer's business. 206 U.S. at 290
