Ericsson has pounced on several vendors selling counterfeit versions of its products at the Cebit technology show in Hanover, Germany.
Ericsson issued 50 warning letters to over 20 manufacturers who were illegally using the Swedish company's logo, or infringing its design rights. Court injunctions were issued to prevent exhibitors displaying or selling fake goods.
A "substantial" haul of fake mobile phone batteries, front panels and cases were spotted by Ericsson's team of representatives at the show, the company said. Cebit, which attracts around 600,000 visitors, started last Thursday and ends tomorrow.
"At Cebit it is easy to identify companies who market counterfeit products or use our trademark in an illegal way," said Niclas Almgren, Ericsson's trademark and design protection manager.
Ericsson said fake products would give customers limited coverage and reduced talk and standby time. The company said customers can recognise fake batteries because its phones automatically charge them at half speed.
Following its Cebit observations, Ericsson said it must now determine whether or not to take legal action.
