The legal spat between Apple and Samsung that has stretched around the world took on additional weight this week, with a new claim lodged against Apple by Samsung in Australia.
Bloomberg reports that Samsung this week went ahead with plans to file a cross claim with a federal court in Australia that takes aim at Apple's iPhone and iPad for infringing on seven wireless patents it holds. The claim also aims to invalidate patents held by Apple that have been used against the company, Bloomberg said.
Last month Samsung announced it would be taking retaliatory action against Apple, which successfully kept Samsung from selling its Galaxy Tab 10.1 tablet in the country as part of a legal agreement. Apple had originally targeted Samsung's devices for infringing on its own intellectual property, with that agreement giving Samsung the option to come up with a special, non-infringing model for the Australian market.
The spat is just a part of a larger battle between the two companies in courts around the world. The dispute was kicked off with a U.S. lawsuit filed by Apple against Samsung in April that said Samsung was violating its intellectual property in the design of its mobile devices, specifically the Galaxy series smartphones and tablets. Samsung later countersued against Apple, saying the company was infringing on multiple patents.
