Duchess of Cambridge trademarks name for use on clothing Kate Middleton's official title has been trademarked to allow use on clothing, footwear and headgear. The Duchess of Cambridge has applied to the Intellectual Property Office to trademark her royal title so that it can be used on "a wide range of goods and services" which could include clothing, footwear and headgear. But before Kate lovers get too excited at the prospect of owning a piece of Duchess-designed clothing, the mother-to-be's title is to be trademarked as part of the Royal Foundation of the Duke and Duchess of Cambridge and Prince Harry, and will be used purely to raise money for a wide variety of charities. IN PICTURES: Kate Middleton's fashion hits and misses "Since the name change of the foundation last year, we have been registering our new name and logo in different territories around the world," a spokesman told The Telegraph 's Richard Eden . As part of that process, we have to choose any categories under which we might conceivably operate in the future. This also protects the foundation against other people using its name illegally. We included clothing in case we choose, for example, to make T-shirts in years to come, for marathon runners, etc. So while a 'Duchess by Catherine' fashion line isn't in the works (and probably never will be), we're betting anything bearing her official moniker would be a hit. Plus, the Buckingham Palace shop does sell a range of jewellery inspired by pieces worn by the Queen and past monarchs so it's not entirely unfeasible that the Duchess's sartorial prowess could one day be used to raise funds.
