Rubber Company v. Goodyear Rubber Company v. Goodyear Rubber Co. v. Goodyear, 76 U.S. (9 Wall.) 788 (1869), is an early decision of the United States Supreme Court recognizing the right of a patent owner to license another person to practice the invention only in a limited field, and holding that such a licensee committed patent infringement when it made and sold products of the invention outside that field. Charles Goodyear invented a process for "vulcanizing" rubber by heating it to a high temperature in the presence of sulfur and lead carbonate or another chemical, so that it was converted from a soft, sticky,
Sulfur disagreeable odor. Hydrogen sulfide quickly deadens the sense of smell and a victim may breathe increasing quantities without noticing the increase until severe symptoms cause death. Dissolved sulfide and hydrosulfide salts are toxic by the same mechanism. Sulfur Sulfur or sulphur is a chemical element with symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S. Elemental sulfur is a bright yellow crystalline solid at room temperature. Chemically, sulfur reacts with all elements except for gold, platinum, iridium, tellurium, and the noble gases. Sulfur
