Motorcyle group accuse designer of using trademark motif illegally.
Hells Angels are suing Alexander McQueen for trademark infringement.
The motorbike group is taking action against the fashion house over the use of a skull design used for its Hell’s Knuckle brass and silver knuckle duster rings.
The suit is also tackling a clutch bag, scarf and dress by the designer that feature a similar design.
Hells Angels are claiming that Alexander McQueen has used its patented skull and wing motif without permission. It is also suing US department store Saks and online retailer Zappos.com that sell the items at the centre of the dispute.
The motorcycle group registered patents for its motif in 1984 and has since authorised its use on clothing and jewellery for promotional purposes. It claims Alexander McQueen was not given such permission.
