Detailed explanation-1: -Edison continued trying to improve this design and on November 4, 1879, filed for U.S. patent 223, 898 (granted on January 27, 1880) for an electric lamp using “a carbon filament or strip coiled and connected to platina contact wires".
Detailed explanation-2: -(Historical footnote: One can’t talk about the history of the light bulb without mentioning William Sawyer and Albon Man, who received a U.S. patent for the incandescent lamp, and Joseph Swan, who patented his light bulb in England.
Detailed explanation-3: -Even the U.S. Patent Office decided in 1883 that Edison’s patent was invalid, as it also duplicated the work of another American inventor. As it happens, Swan and Edison worked from bulb designs that had been in use since the early 1800s.
