You may remember that last year Cadbury was blocked by rival Nestlé in its attempt to trademark the distinctive purple it had been using for its chocolates for more than 100 years (now defined as Pantone 2685C). Now it's Woolworth's turn to be the spoiler, via its objections that have led to the rejection of oil giant BP's twelve-year attempt to trademark the use of Pantone 348C, the green it employs for much of its branding. In this case the decision was made by the Australian intellectual property authorities, in contrast to BP's earlier victories in England and Europe.
This made us wonder how many firms have been successful in trademarking the use of color in their branding. We've rounded up some examples below — just point us to any notable examples we've missed and we'll add them.
