A long-standing infringement dispute between Apple and Samsung took one step closer to resolution this week following a ruling from the U.S. International Trade Commission. The exclusion order calls for a limited sales ban on Apple mobile devices supported by AT&T networks across the country.

"The Commission has determined that the appropriate remedy is a limited exclusion order and a cease and desist order prohibiting Apple from importing into the United States or selling or distributing within the United States wireless communications devices, portable music and data processing devices and tablet computers that infringe [the asserted Samsung patents]," ITC officials stated in their final determination.

The injunction will affect the iPhone 3G, iPhone 3GS, iPhone 4, iPad 3G and iPad 2 3G. President Obama will now review the decision for up to 60 days, and the sales ban would go into effect barring his veto. However, Apple is planning to appeal the ITC ruling in federal appellate court.

While this may deal a blow to Apple's reputation as a primary innovator, analysts insist the commercial impact may be inconsequential. Maynard Um of Wells Fargo Securities told Apple Insider that he expects a new iPhone model to debut in September and limit any negative effects of the ITC order to a matter of weeks.
