The lastest round of fighting between Apple and Samsung goes to the Cupertino Kid. A Japanese court ruled favorably for Apple in a suit filed by Samsung alleging that Apple had misused 3G wireless patents in several versions of the iPhone.
As noted by Apple Insider, Samsung's lawsuit in this case goes back to April of 2011, when the Korean electronics giant sought an injunction against the iPhone for unauthorized use of specific data transmission patents. A ruling today found that Samsung doesn't have the right to assert those 3G patents in court.
Samsung had also recently made a request to a California federal court seeking documents from the Apple v. Samsung patent trial, hoping to use those documents in discovery for a similar case in Japan. The move was seen by Apple as an attempt by Samsung to sneak around the usual Japanese court procedures, and the US court agreed with the company.
