Apple Inc. and Samsung Electronics Co., which sued each other in a German court over technology used in tablets and mobile phones, both face hurdles in showing the patents they assert cover the methods used, a judge said.

Samsung sued Apple over mathematical coding procedures in processors. Apple sued Samsung over features for unlocking touch screens. Each may have trouble showing the other is violating the patents, Presiding Judge Andreas Voss in Mannheim, Germany, said today at two hearings.
