David registered his name in 2000, VB in 2002 and all three boys, Brooklyn, Romeo and Cruz, are trademarked too.
This is published unedited from the IANS feed. Brand Beckham is spreading like a wildfire in the consumer market.
The application filed in December names Victoria Beckham as the holder of the rights as parent and guardian.
And of course Brand Beckham world domination doesn't just stopped at adorable Harper.
Intellectual property expert Oliver Bray told Daily Mail the trademark move for someone as young as Harper was unusual, but he also praised Victoria for being "savvy" and "looking to the future".
Harper was named by David and Victoria Beckham after renowned author Harper Lee, who penned Victoria's favorite book, To Kill A Mockingbird, which was adapted into a hit film in 1962.
This suggests that Harper could have the option of going into the music biz like her 42-year-old mum did back in her Spice Girls days if she wants to. Their sons Brooklyn, 18, Romeo, 14, and Cruz, 12, have their own trademarks, as well.
If ever there was a sign that you are a fully-fledged member of a showbiz dynasty, it's when you get your name trademarked for exclusive commercial use at five years old. Their names were officially registered to the UK's Intellectual Property Office and the EU-wide office.
Over the years, Brand Beckham has grown beyond a retired footballer and his family.
The Beckham empire is estimated to be worth over £500million in lucrative brand sponsorship and business enterprises.
Trademarks last for 10 years, so Harper will be covered until she turns 15.
The move means Victoria has the rights to use Harper's name on products such as aromatherapy oils and anti-wrinkle cream.
