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 was proposed in 1920 by Hermann Staudinger, who spent the next decade finding experimental evidence for this hypothesis. Polymers are studied in the fields of biophysics and macromolecular science, and polymer science (which includes polymer chemistry and polymer physics). Historically, products arising from the linkage of repeating units by covalent chemical bonds have been the primary focus of polymer science; emerging important areas of the science now focus on non-covalent links. Polyisoprene of latex rubber is an example of a natural/biological polymer, and the polystyrene of styrofoam is an example of a synthetic polymer. In biological contexts, essentially all biological
