Harper Beckham's teen beauty brand is like 'Chanel for acne' as first details are revealed amid parents David and Victoria's trademark battle in US

Her mother’s beauty empire is worth a fortune, selling an eyeliner every 30 seconds.

And now Harper Beckham is creating her own skincare line to help her fellow teenagers manage of of the main blights of adolescence: spots.

The Beckhams are selling the 'Harlo by Harper' range as being like ‘Chanel for acne’.

Lady Beckham, who also runs a fashion label, previously revealed how Harper came to her ‘two or three years ago and she was really struggling with her skin’.

She told entrepreneur Emma Grede: ‘She used to have beautiful skin, but then, like all young girls, she was enticed by certain beauty brands and she was putting a lot of product on her face that wasn’t suitable for her skin.’

Harper then came to her with the idea of her own products, telling her mother: ‘I really want to create a brand because I know what I want, what I can’t find, and I don’t want other people to have to go through what I have been through.’

But teenage fans over the pond keen to try the new products will have to wait, as a battle rages in the US over the label's trademark.

The 15-year-old’s range has not been rubber-stamped in the US due to similarities with an American dietary supplements firm.

A Las Vegas company, Drink Harlo LL,C already sells nutritional goods under the name HARLO in the US. 

Now lawyers for Sir David, 51, and Lady Beckham, 52, have fought back against the US Patent and Trademark Office with a robust 122-page argument after their trademark application was refused.

They claim that Harper’s new company will be concentrating on cosmetics, specifically for teenagers dealing with acne.

One of the main classifications of the brand lists ‘acne medications; Acne treatment preparations; Medicated facial cleansers’.

It was successfully registered in the UK on October 9 and in the EU last summer, but it is still pending in the US and Canada. Sources say it’s important for the trademark to be registered in the US due to the size of its market.

The US examiner refused the bid last month claiming that Harper’s products could be construed as 'a new or additional product line' from Drink Harlo LLC.

But Harper’s lawyers insist the two can never be mixed up, saying: 'A consumer who purchases a lipstick, a shampoo, or a body wash is purchasing a product to be applied to the exterior of the body for cosmetic or hygienic purposes.

'A consumer who purchases a vitamin or herbal supplement is purchasing a product to be swallowed for nutritional purposes.

'These products are neither competitive nor complementary; one cannot be substituted for the other, and neither is used with or in support of the other.'

Their legal team added that supplements 'are commonly associated with diet, nutrition, and fitness, whereas Applicant’s goods speak to beauty, grooming, and personal care.’

They even defend the name 'Harlo by Harper' saying it’s 'an alliterative, five-syllable phrase in which the shared ‘Har’ opening of Harlo and Harper binds the two halves into a rhythmic, unitary whole that resists dissection, both audibly and conceptually'.

It was also pointed out that Chanel has registered its famous ‘CC' for 'perfumery, cosmetics, and toiletries' – while an entirely separate owner Angelice Alexander Martin holds ‘CC' for 'vitamin supplements’.

'The USPTO’s [US Patent and Trademark Office] own register confirms that consumers do not expect cosmetics and personal care products, on the one hand, and dietary supplements, on the other, to emanate from a single source,’ the filing states.

'The Office has repeatedly permitted identical and nearly identical marks to coexist on the Principal Register, under separate ownership, for these respective goods.'
