A campaign to hunt out unscrupulous dealers who sell fake Mercedes-Benz parts has been launched by Mercedes-Benz in the UK. Legal action is being taken against 20 firms who Mercedes-Benz claims have infringed their intellectual property rights. Mercedes-Benz estimates it is losing up to £5-million a year to bogus traders. The company has taken legal action in the past, but now it is mounting a determined campaign to stamp out the illegal traders.
