Samsung has lost its UK patent battle with Apple, days after announcing it would seek further cuts to the damages awarded to Apple in a US patent case.
The setback also comes just a week after the South Korean smartphone maker failed to win an iPhone ban in Japan, according to the BBC.
Samsung is fighting claims against Apple in several courts around the world, including France, Germany, the Netherlands, Italy, South Korea, Japan and the UK, but has lost more than it has won.
In the latest UK case, Samsung said Apple had infringed three of its patents with technology that iPhones use to send and receive data over 3G networks.
Samsung said in a statement that 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," the statement said.

Last October, Apple lost an appeal against the UK court ruling which said Samsung is innocent of any copyright infringement relating to the Galaxy Tab.
The iPad manufacturer claimed that since 2010 Samsung had copied a number of its designs for its own Galaxy Tab to compete in the market.
In July 2012, Judge Colin Birss ruled in July that the Samsung tablet was not “cool” enough to be confused with Apple’s market-leading iPad, and ordered that the Cupertino-based company ran adverts to publicise the ruling to consumers.
Apple was given 21 days to appeal the ruling, but the judges presiding over the case have upheld their ruling again and insisted the company run the adverts as “the acknowledgment must come from the horse's mouth”.
The rival smartphone and tablet makers have been locked in legal battles since 2011, when Apple first sued Samsung in the US for alleged intellectual property infringements.
