Samsung Electronics began its attack on patents Apple has asserted in a $2 billion case by trying to convince jurors that the iPhone maker exaggerated claims about inventions allegedly copied by the Galaxy maker.

Samsung, trying to avoid a repeat of two years ago when jurors found infringement and awarded Apple $1billion in damages, is calling on witnesses with smartphone technology expertise, including engineers from Google, to argue that some of Apple's technology is so obvious it shouldn't have been patented.
