Apple has sued Samsung in the U.K. courts, further expanding the myriad countries in which it has taken legal action against the Korean manufacturer over its Android products.
The suit was filed on Monday, Samsung told ZDNet UK, explaining that it was a countersuit against action Samsung filed with the High Court in June. Details of both suits remain sketchy, as the patents in question have not been identified in these cases.
Apple's U.K. action against Samsung takes to at least 20 the total number of patent suits between the two companies that are currently under way. Apple says Samsung's Android smartphones and tablets infringe on Apple patents, while Samsung says Apple's products, such as the iPhone, infringe on Samsung's patents.
