Question: What is this law that originally comprised seven articles that entrench the doctrine of the separation of powers in the United States, whose clause was reaffirmed by the decision from Lambert v. Yellowley?
Sentence (from "Ethyl Gasoline Corp. v. United States"): Ethyl Gasoline Corp. v. United States, 309 U.S. 436 (1940), was a decision of the United States Supreme Court that limited the doctrine of the Court's 1938 decision in "General Talking Pictures Corp. v. Western Electric Co." Beginning with the 1926 decision in "United States v. General Electric Co.", the Supreme Court made a sharp distinction between (i) post-sale restraints that a patentee imposed on purchasers of a patented product and (ii) restrictions (limitations) that a patentee imposed on a licensee to manufacture a patented product: the former being illegal and unenforceable under the exhaustion doctrine while the latter were generally permissible under a lenient "rule of reason."
Relevant evidence: No
