According to The Daily Mail, courtiers are planning to warn businesses that they risk infringing copyright and trademark rules if they use her full name.
A royal aide told the paper: “It is highly unlikely that we would have any objection if a company wanted to call a dress ‘the Kate dress’. ‘Kate’ isn’t specific to Catherine Middleton. It may, however, be a different scenario if it was called the ‘Catherine/ Kate Middleton dress’ as that impacts… on personal copyright. Or indeed if a company was suggesting a dress was officially endorsed by Catherine.”
Brand Kate has become a major money-spinner since she announced her engagement to Prince William in November.
The royal blue Issa dress she wore for the announcement sold out within a day, and copycat versions by high street stores Tesco and Peacocks flew off the shelves.
More recently the £159 Reiss Nanette gown which she wore for the couple’s Mario Testino-shot engagement photos appeared on ebay for £370. The store is now planning to re-issue the sold-out dress.
