Now Louboutin has gone to court to protect its trademark red soles against YSL, which is also marketing high-fashion shoes featuring red soles.
The legal battle is far from over. Last week, the judge refused to stop YSL from selling its red-soled shoes. As reported in The Independent, the judge was particularly concerned about the ability to trademark a colour:
'[The judge] went on to argue that any restriction of colour was potentially detrimental both creatively and commercially. It would be like Pablo Picasso trying to sue Claude Monet for using an indigo too close to the "colour of melancholy" that defined the former's Blue Period, [the judge] suggested."'
