Any patent was moot on this formulation, The RAF were not allowed to
manufacture it. They developed it but the RAF was government funded
and therefore the formulations were Government owned, the manufacture
was done by various paint suppliers, by tender. 
By 1917 both the RFC and the RNAS were being ordered to use PC10
whenever possible to aide in consistency of supplies and supply
chain. Prior to that the RNAS had there own methods of doping...
Thats why the RNAS  were slow to use PC10.
