Apple and HTC are exchanging blows in a London court case over claims the Taiwanese manufacturer infringes on four Apple patents, says a Bloomberg report. These patents cover various multi-touch gestures, photo zooming and scrolling, slide-to-unlock and the use of a multilingual alphabet when sending text messages.

HTC argues that it does not infringe on these patents because "We are dealing with extremely simple implementations of commonly known techniques." This is one of several lawsuits between the two companies, and a win over Apple in the UK could help HTC in these other cases.
