Google has announced that its acquisition of Motorola Mobility has finally closed.

The purchase of Motorola Mobility has come to completion for a total sum of $12.5bn (£7.9bn). Google said that together the firms will ' accelerate innovation and choice in mobile computing'.

Larry Page, CEO of Google said: "Motorola is a great American tech company that has driven the mobile revolution, with a track record of over 80 years of innovation, including the creation of the first cell phone."

"And as a company who made a big, early bet on Android, Motorola has become an incredibly valuable partner to Google."

The deal sees Google gain Motorola Mobility’s patent portfolio which will apparently "help protect the Android ecosystem". As well as patents the future looks promising for devices with Google promising "better phones at lower prices".

As part of the acquisition Sanjay Jha, CEO of Motorola Mobility, has stepped down to be replaced by Google's Dennis Woodside.

"I’m confident Dennis and the team at Motorola will be creating the next generation of mobile devices that will improve lives for years to come." added Page.
