MAR 2, 2018, Phoebe French: The Drinks Business discusses the choice to trademark the colour of beer, and the effect it will have on the sharing nature of the industry.
“Owner Stephen Wools quipped: “Maybe Heineken, VB or XXX Gold will have to tweak the colour of their liquid to avoid any trademark infringements. They might own the taps pouring the beer but we own the colour of beer”.
Quite how serious the application actually is, remains to be seen. Companies such as Cadbury and BP have both previously tried to trademark the colours used in their branding, but without success.”
