Thomas A. Edison, famed inventor of the first practical incandescent lamp, was granted U.S. Pat. 223,898<\/a> on January 27, 1880, which claimed \u201ca filament of carbon of high resistance.\u201d<\/p>\n\n\n\n

Months after filing his application, Edison discovered a carbonized filament from bamboo in Japan could burn 1,200 hours. His patent was invalidated by the Patent Office based on an earlier patent to Sawyer, U.S. Pat. 205,144<\/a>, but eventually upheld after six years of litigation.<\/p>\n\n\n\n

Westinghouse sued Edison’s company, General Electric, under the Sawyer patent in a case that went to the Supreme Court, The Incandescent Lamp Patent, 159 U.S. 465 (1895)<\/a>.<\/p>\n\n\n\n

The Court invalidated Sawyer’s patent noting that the materials described therein \u201cwere found to be so inferior to the bamboo, afterwards discovered by Edison, that the complainant was forced to abandon its patent in that particular, and take up with the material discovered by its rival.\u201d<\/p>\n\n\n\n

Edison’s famous quote \u201cI\u2019ve not failed. I\u2019ve just found ten thousand ways that don\u2019t work” reflects his work in finding a material suitable for an incandescent bulb.
