Microsoft Files Complaint Against Motorola in Europe

NYT - BRUSSELS — Microsoft filed a complaint Wednesday with European Union antitrust authorities accusing Google and Motorola Mobility, a smartphone company the Internet search giant plans to buy, of charging too much for use of its patents, marking a new stage in a long-running feud between Microsoft and Google.

“We have taken this step because Motorola is attempting to block sales of Windows PCs, our Xbox game console and other products,” David A. Heiner, a senior Microsoft lawyer, wrote in a blog post Wednesday.

The move ratchets up pressure on Google, which reached agreement last year to acquire Motorola Mobility for $12.5 billion in its largest deal to date. Google already is under investigation by the E.U. authorities for possible abuses of a dominant position in online search and advertising, and Microsoft is among the complainants in that case, too.
