Samsung loses patent fight against Apple in the UK
South Korean phone-maker Samsung has lost another patent fight against rival Apple, in the UK High Court.
Samsung had said technology used in Apple products to allow phones to send and receive data over 3G networks infringed three of its patents.
The case comes a week after Galaxy smartphone manufacturer failed to secure an iPhone ban in Japan.
Samsung has pursued a number of claims against Apple in courts worldwide, but has won only a minority of the cases.
It said in a statement it was disappointed by the court's decision and would consider whether to file an appeal.
"For decades, we have heavily invested in pioneering the development of technological innovations in the mobile industry, which have been constantly reflected in our products," a spokeswoman said.
Apple declined to comment.
Legal battles between the two companies began in 2011, when Apple first sued Samsung in the US for alleged intellectual property infringements.
Other court cases have taken place in France, Germany, the UK, the Netherlands, Italy, South Korea and Japan.
