United Kingdom

While as of yet, the United Kingdom does not officially recognize an Inventor's Day, in 2014 BT made a public appeal to celebrate "the first" National Inventor's Day on 2 December 2014. While many countries celebrate inventiveness on a significant day relating to one of that country's inventors, 2 December does not appear to have such a relationship. However, the day was also the release of a study by BT of the inventiveness of UK residents. As of 9 November 2016 there has not been any announcement of a second or subsequent National Inventor's Day in the United Kingdom.
