Samsung also seeks to have the patents that Apple claims were infringed upon by Samsung's Galaxy series, revoked and invalidated. Apple started the battle, as we reported, by claiming back in April that Samsung copied the design for its Galaxy S line from Apple's iPhone and iPad. So far, in Germany and Australia, Apple has won injunctions against Samsung preventing the latter from selling its Samsung Galaxy Tab 10.1 in those countries. In the Netherlands, Samsung is barred from offering three smartphones including the Samsung Galaxy S II.
In announcing its lawsuit against Apple, Samsung pointed out its history of innovation in the mobile arena, stating that the company has continuosly invested in research, design and technology enabling them to produce "cutting-edge" mobile products.
