It’s not just Apple that’s calling Samsung a patent-infringer. The US ITC said Thursday that it will investigate Samsung for possible trade violations at the request of Ericsson. At issue are mobile technology patents used in a number of the Korean manufacturer’s smartphones, tablets, and TVs. To many, the case will seem retaliatory, after Samsung accused Ericsson of its own violations last year. This is starting to sound like deja vu all over again. [Source: AlltThingsD]
