Samsung products have been banned after a lawsuit found that the South Korean firm had infringed two Apple patents.
The US International Trade Commission (ITC) has banned the sale and import of some products manufactured by Samsung after the finding, but dismissed four other claims made by the iPhone maker.
Both Samsung devices cited by the commission in its ruling were 2010 models which include the Continuum SCH-1400 and the Transform SPHM920.
An ITC spokesperson said: "The commission has determined that the appropriate remedy is a limited exclusion order prohibiting Samsung from importing certain electronic digital media devices that infringe one or more of Apple’s patents."
An Apple spokesperson told the Financial Times: "With today’s decision, the ITC has joined courts around the world in Japan, Korea, Germany, Netherlands and California by standing up for innovation and rejecting Samsung’s blatant copying of Apple’s products. Protecting real innovation is what the patent system should be about."
Samsung spokesman Adam Yates said the company was disappointed by the court’s ruling.
Yates added: "Apple has been stopped from trying to use its overbroad design patents to achieve a monopoly on rectangles and rounded corners."
