Apple and Samsung, the world's largest consumer electronics corporations, are waging legal war in several countries, accusing each other of patent violations as they vie for supremacy in the market for mobile devices.

Friday's decision, by US District Court judge Lucy Koh, in San Jose, California, was made days after she slapped a pre-trial ban on sales of Samsung's Galaxy Tab 10.1, a tablet computer that runs on Google's Android operating system and goes toe-to-toe with the iPad.

The back-to-back triumphs - significant because pre-trial injunctions are rarely granted - meant Apple had a better week in court than on the previous week, when Chicago Federal Court judge Richard Posner ruled that it could not pursue an injunction against Google's Motorola Mobility, effectively ending that case.

"Apple has made a clear showing that, in the absence of a preliminary injunction, it is likely to lose substantial market share in the smartphone market and to lose substantial downstream sales of future smartphone purchases and tag-along products," Judge Koh said in Friday's ruling.

She scheduled a hearing today to consider putting the Galaxy Nexus injunction on hold pending appeal.

Apple has waged an international patent war since 2010 to limit the growth of Google's Android system, the world's most-used operating system for mobile devices. Apple opponents say it is using patents too aggressively to stamp out competition.

As a condition of the injunction, Apple was ordered to post a bond of more than $95-million to secure payment of damages sustained by Samsung should the injunction be deemed a wrongful decision later. The order will become effective upon posting of the bond.
