Samsung loses Galaxy Tab 10.1 sales ban appeal and faces Apple patent trial.

Korean consumer electronics giant Samsung has lost its bid to overturn last week's ban on US sales of its Galaxy Tab 10.1, setting the scene for a tense patent trial with Apple, commencing 30 July.

US District Judge, Lucy Koh, who also barred the Galaxy Nexus smartphone from US shelves on Friday at Apple's behest, yesterday dismissed Samsung's appeal against the pre-trial sales injunction instigated on 26 June in relation to the tablet.

"Samsung is disappointed with the court's decision that denied our motion to stay. We believe today's ruling will ultimately reduce the availability of superior technological features to consumers in the United States," the Seoul-based firm said in a statement.

Apple and Samsung are currently locked in legal conflict across a range of countries as they attempt to gain the upper hand in the competitive global market for mobile smart devices.

Apple has seized the initiative on its home soil by obtaining the rare pre-trial sales embargos against the Nexus and the Tab 10.1, with the patents being contested relating to everything from Siri-like voice-activated user assistance functions to cosmetic design features.

Samsung has also launched a separate appeal against last week's Galaxy Nexus ban, which is expected to be heard later this week.

Demand for Samsung's latest smartphone, the Galaxy S3, continues to soar as Apple readies its 'iPhone 5' for an expected autumn release.
