Edison's Light Bulbs go to Auction

A collection of twenty two light bulbs belonging to Thomas Edison have been auctioned in London.

The set, which were used in 1890 as evidence in a Patent infringement claim, has been reported as expected to have reached £300,000.

Thomas Edison was granted a US Patent for the light bulb in 1880. However an earlier Patent was awarded in the UK to Sir Joseph Swan dispelling the common held view that Edison was the inventor of the light bulb. Edison spent most of his life defending his Patent.

The sale took place on the 13 December 2006.
