Microsoft's smartphones can continued to be imported and sold in the US, according to a ruling this week by the U.S. International Trade Commission. Their decision overturned a previous ruling by a judge in April, who stated Microsoft had violated two patents owned by InterDigital.

The dispute over these patents, which concern optimising a cellphone's power to connect to a network, first started way back in 2007, when InterDigital sued Nokia, claiming that the company had infringed on their property by using them in their phones without the proper licence or payment. Microsoft acquired Nokia's Devices and Services business in 2014, which included the ongoing court battle with InterDigital.

According to Reuters:

"In April, the U.S. trade judge ruled that Microsoft used InterDigital's patents, considered standard in the industry, but refused to pay for a license to them. An import ban would have affected any Microsoft phone using 3G cellular technology, including its Lumia smartphones."

"After reviewing that ruling, the commission said on Friday that Microsoft did not violate the patents, but it did not address the issue of fair licensing for essential patents."

"Earlier this month, Microsoft sued InterDigital in Delaware federal court, claiming InterDigital violated U.S. antitrust law by breaking promises to offer licenses on reasonable terms."
