Google has acquired Quickoffice, which produces mobile office productivity applications for Android, Apple iOS and Symbian handsets.

Quickoffice enables users to access Microsoft Office documents and update them from a mobile device.

Microsoft has revealed a new application that’ll bring entertainment from its Xbox gaming console to other devices. Xbox SmartGlass will launch later this year for Windows 8 devices and Windows Phone handsets.

For example, it’ll be possible to browse the web on your Xbox while using your mobile device as a remote control. Similarly, bonus features from TV shows could appear on your smartphone or tablet while you’re watching your television.

Three months ago Microsoft took advantage of Mobile World Congress to announce the public ‘preview’ version of Windows 8. It’s now moved beyond this beta version to announce the availability of the Windows 8 Release Preview, which is the final development phase before the OS goes into commercial production.

The new tablet and computer operating system can be downloaded by customers who are currently using Windows XP, Vista, Windows 7 or the previous Windows 8 preview, depending on their equipment specifications.

A court in Germany has ruled that Motorola Mobility mobile phones have infringed a Microsoft patent. It’s the first defeat for Motorola Mobility since its acquisition by Google was completed earlier this week.

The patent allowed mobile phones to send text messages that were longer than a network would normally permit by breaking them up and then reassembling them.

The United States International Trade Commission has ordered an import ban for certain Android-based Motorola Mobility devices.

It follows a ruling that a number of Motorola mobile devices infringe a Microsoft patent for ‘generating meeting requests and group scheduling from a mobile device’. Nine patents were listed in the original complaint from October 2010.
