A Royal Commission on Awards to Inventors is a periodic Royal Commission of the United Kingdom used to hear patent disputes.
On October 6, 1919 a Royal Commission on Awards to Inventors was convened to hear 11 claims for the invention of the tank; one of the eleven "claimants" was a team of two (thus there were 12 individuals involved).
A Royal Commission on Awards to Inventors was established in 1946 to hear claims of inventors who "allege that their inventions, drawings or processes have been used by Government Departments and Allied Governments during the War".
