Samsung is being hit with 278 claims of patent infringement across 10 devices in its Australian battle with Apple, including some models not yet sold in the country like the Galaxy Tab 7.0. The complaints now cover 22 patents, making this a massive expansion over the original three patents that Apple claims Samsung infringes with its Galaxy Tab 10.1, which was briefly the subject of a sales injunction last year. Samsung's lead barrister Neil Young SC told The Australian that Apple had "given only days notice" of its expanded claims, meaning that the trial could be pushed back from next month to mid-May to allow Samsung time to form a defense.

Despite only managing to lift the injunction against the Galaxy Tab 10.1 weeks before Christmas, Samsung has been using the case to generate publicity, marketing the Tab as "the tablet Apple tried to stop." For its part, Apple is preparing evidence in its defense against Samsung's claims that it infringes its patents covering 3G connectivity — a case that may not be heard until November of this year.
