On June 15, 1844, Charles Goodyear was granted a patent for the vulcanization of rubber, a process by which what element, represented by the symbol S, is added to rubber?
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,
Charles Goodyear Charles Goodyear Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844. Goodyear is credited with inventing the chemical process to create and manufacture pliable, waterproof, moldable rubber. However, the Mesoamericans used a more primitive stabilized rubber for balls and other objects as early as 1600 BC. Goodyear's discovery of the vulcanization process followed five years of searching for a more stable rubber and stumbling upon the effectiveness of heating after Thomas
