Microsoft Corp. (MSFT) said Wednesday it has filed a competition complaint with the European Commission against Motorola Mobility Inc (MMI) and its soon-to-be owner Google inc. (GOOG) in connection with Motorola's handling of patents it holds that form part of industry-wide standards for Internet connectivity.

The patents in question involve wireless access to the Internet and online video streaming and affects products like Microsoft's laptops and Xbox games consoles.

Microsoft charges that Motorola's high charges for the use of its patents are in breach of an industry agreement to make patents in industry standards available to all manufacturers at a minimum cost.

It also complains that Motorola is seeking to block sales of products using these patents if the payments aren't made.

"In legal proceedings on both sides of the Atlantic, Motorola is demanding that Microsoft take its products off the market, or else remove their standards-based ability to play video and connect wirelessly," Dave Heiner said on the Microsoft blog. Heiner is Vice President & Deputy General Counsel, Corporate Standards & Antitrust Group at Microsoft.

"The only basis for these actions is that these products implement industry standards, on which Motorola claims patents," Heiner said.

A spokesman for the EU commission confirmed receipt of Microsoft's complaint, and said the commission will examine it.

Apple Inc. (APPL) has also recently filed a suit in California aimed at warding off any injunctions from Motorola Mobility on one of Apple's iPhones and last week made a similar complaint to the European Commission.

Motorola has accused Apple of patent violation in the iPhone 4S, but Apple claims it is protected under a license agreement from Qualcomm Inc. (QCOM)

Last week, antitrust authorities in the U.S. and European Union approved Google Inc.'s (GOOG) $12.5 billion acquisition of Motorola Mobility.

"Google as its new owner doesn't seem to be willing to change course," Microsoft said.
