Samsung is going to have to stop importing some models of its smartphones and tablets into the U.S. after President Obama's administration upheld a ban won by Apple in a patent-infringement dispute, reports "Bloomberg" (http://tinyurl.com/mp7gq3l).

"After carefully weighing policy considerations, including the impact on consumers and competition, advice from agencies, and information from interested parties, I have decided to allow" the import ban to proceed, Obama’s designee, U.S. Trade Representative Michael Froman, said in a statement.

The import ban is on a limited number of products. The ITC said newer models by Suwon, South Korea-based Samsung had worked around two Apple patents, which covered a multitouch feature and one for a sensor for headphone jacks.
