Samsung has suffered a setback in its ongoing legal battle with Apple over alleged patent violations after a Tokyo court rejected its request for injunction to stop iPhone sales in Japan, reports “The Asahi Shiumbun” (

The Tokyo District Court rejected the South Korean technology giant’s claims in September and October, saying there had been no patent infringement by the U.S. company’s Japanese unit. The patents in question involve the technology for downloading an app to add new functions to a smartphone and the so-called airplane mode, which suspends a phone’s communications without turning off the power during flight.

This is all part of the ongoing, global legal battle. Apple and Samsung have filed more than 30 lawsuits against each other across four continents. For example, Apple alleges that Samsung copied the slide-to-unlock technology of its iPhone and iPad devices.
