10. The YSL vs. Christian Louboutin “Red Soles” suit:
So this happened—famed shoe designer Christian Louboutin filed a lawsuit against YSL in April for trademark infringement, claiming that red-soled shoes are a signature that is associated with his brand name. Louboutin lost it when YSL’s Cruise 2011 collection showed four styles of shoes with red bottoms, and the designer wanted them to be discontinued immediately. Not shockingly, the court ruled that “the color red” on the soles of shoes could not be granted trademark protection, and when this case ran on national news outlets like Huffington Post, MSNBC, and CNN, the world shared a good laugh.
