The U.S. Department of Justice (DOJ) has given its approval to Microsoft's pending acquisition of Nokia's mobile devices and services business.

The transaction got the DOJ nod on November 29, according to the Federal Trade Commission's Bureau of Competition notification on December 2.

"We look forward to the date when our partners at Nokia will become members of the Microsoft family, and are pleased that the Department of Justice has cleared the deal unconditionally," said a Microsoft spokesperson in a prepared statement.

Last month, Nokia shareholders gave their approval to the deal during an extraordinary general meeting in Helsinki. Indian authorities gave their approval to the Microsoft-Nokia deal earlier this fall.

The next hurdle for the deal will be the European Union. Antitrust regulators there are on tap to decide whether or not Microsoft's bid breaches the EU's competition rules. Reuters reported in October that the European Commission would decide by December 4 whether or not to clear the acquisition. (It can extend the review by an additional 10 business days if needed to weigh possible concessions by Microsoft if there are any concerns.)

Microsoft went public with plans to buy Nokia's devices and services business , plus license a number of its patents, for $7.2 billion in September. Microsoft officials have said they expect the transaction to be completed around the first quarter of 2014.
