Headnotes

  1. Patent Law — Licensee Estoppel A patent licensee sued for royalties under a licensing agreement containing a price-fixing covenant is not estopped to challenge the validity of the licensor's patent, where the licensee invokes federal law to contest the patent's validity, its alleged misuse, and the price-fixing covenant. 329 U.S. at 407
  2. Patent Law — Licensing A covenant to pay royalties is not severable from a covenant to sell patented articles at fixed prices, so the licensee's challenge to the price-fixing covenant reaches the royalty obligation. 329 U.S. at 407
  3. Patent Law — Federal Question — State Law Where a licensee invokes federal law to challenge the validity of a patent, the alleged misuse of the patent, and a price-fixing covenant, the contentions raise federal questions not governed by state rules of estoppel or contract severability. 329 U.S. at 407
  4. Patent Law — Price-Fixing — Antitrust If a patent is determined to be invalid, a price-fixing agreement in the license violates the antitrust laws. 329 U.S. at 407
