(REUTERS) - World No. 1 Internet search engine Google is seeking EU regulatory clearance of its planned purchase of handset maker Motorola Mobility Holdings, the European Commission said on its Web site on Monday.

Google unveiled the $12.5 billion deal to boost its patent portfolio in August, seen as a defensive move against rivals such as Apple Inc.

The Commission will decide by Jan. 10 whether to clear the deal, which was notified to the regulator last Friday, the Commission Web site showed.

The Department of Justice is now assessing the proposed takeover. The EU Commission is also investigating Google's business practices following complaints from smaller rivals.
