BERLIN (AP) — A German court has dismissed Apple Inc.'s claim that Samsung Electronics and Google Inc.'s Motorola Mobility infringed patents used in touch-screen devices.

The Mannheim state court's ruling Friday follows similar decisions in Britain and the Netherlands.

The ruling can be appealed within 30 days.

Apple and its rivals are locked in a complex worldwide battle over patents and design rights covering the lucrative market for smartphones and tablet computers.

Last month a U.S. court ruled that Samsung phones and tablets infringe on Apple patents, and awarded the Cupertino, California, company $1.05 billion.

Meanwhile, Samsung is seeking royalties from Apple for sales of iPhones it says infringe on its patents.
