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,
Polymer capacitor polymer e-caps in which a solid conductive polymer forms the electrolyte, this is much more difficult to achieve, because its conductivity comes by a chemical process of polymerization. However, the benefits of a solid polymer electrolyte, the significantly lower ESR of the capacitor and the low temperature dependence of the electrical parameters, in many cases justify the additional production steps as well as higher costs. Electrolytic capacitors with the charge transfer salt tetracyanoquinodimethane TCNQ as electrolyte, formerly produced by Sanyo with the trade name "OS-CON", in the true sense of the term "polymer" were not "polymer capacitors". TCNQ electrolytic capacitors
