Talk:Joseph Swan

Check the Patent dates
Check: Swan’s and Edison’s patents for electric light bulb were both in 1979? Thomas Edison received his U.S. Patent on 27 January 1880 (https://www.archives.gov/milestone-documents/thomas-edisons-patent-application-for-the-light-bulb#:~:text=On%20January%2027%2C%201880%2C%20Edison,his%20electric%20lamp%20is%20223%2C898.), whereas Sir Joseph Swan received his U.K. Patent for the same on 27 November 1880 (https://en.wikipedia.org/wiki/Joseph_Swan). 125.235.239.244 (talk) 09:02, 3 June 2023 (UTC)
