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,
Silicone rubber cured by a platinum-catalyzed cure system, a condensation cure system, a peroxide cure system, or an oxime cure system. For the platinum-catalyzed cure system, the curing process can be accelerated by adding heat or pressure. In a platinum-based silicone cure system, also called an "addition" system (because the key reaction-building polymer is an "Addition reaction"), two different chemical groups (a silicone hydride and a vinyl) react in the presence of platinum (which serves as the catalyst). In this reaction, an ethyl group [C(H2)- C(H2)] is formed and there are no byproducts. Two separate components must be mixed to catalyze the
