The fashion world had been abuzz in 2012 and 2013 about footwear designer Christian Louboutin's claim of exclusivity to the use of the colour red on the sole of footwear. Battles over claims of rights in particular colours did not, however, end with the resolution of the Louboutin case and have extended beyond just the fashion industry. The issue of ownership of colour trade marks recently raised its head again in a precedential decision issued by the USPTO's Trademark Trial and Appeal Board (TTAB) addressing a petition for partial cancellation or restriction of registration filed by Covidien LP against a trade mark registration owned by Masimo Corporation.
