Microsoft, Google at it again: Microsoft and Google are still fighting, this time a bit more officially than through competing statements and blog posts. Microsoft announced Wednesday that it had filed a complaint against Motorola Mobility and Google.

Microsoft’s complaint, filed with the European Commission, states that Motorola is trying to block sales of Windows PCs, Xbox consoles and other products because the devices use the Internet to view video on the Web.

“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,” wrote Dave Heiner, deputy general counsel for Microsoft’s corporate standards and antitrust group in a blog post. He goes on to say that Google — through Motorola Mobility — is trying to force Android competitors off the market using these patents.

Google did not respond to a request for comment on the complaint.

FCC chairman calls for cybersecurity protection: Federal Communications Commission Chairman Julius Genachowski delivered remarks Wednesday urging the technology and telecommunications industry to adopt standards to protect consumers from cyber attacks.

In a speech delivered at the Bipartisan Policy Center, Genachowski called for all broadband providers to begin implementing secure procedures such as DNSSEC and said that it must be implemented with privacy in mind.

But preserving the Internet’s openness, he said, must be a top priority. “Preserving the openness of the Internet is not a concern to be balanced with security risks, it is a guiding principle to be honored as we seek to address security challenges.”

ACTA up for review in European court: On Wednesday, the European Union decided to have its highest court review the Anti-Counterfeiting Trade Agreement and determine whether the treaty violates freedom of expression. Opposition to the proposal has sparked protest across Europe from those who take exception to the treaty’s attempts to police online piracy.

The BBC reported that the European Commission has decided to ask the Court of Justice to clarify whether the treaty signed by 22 EU member states adequately protects freedom of expression and freedom of the Internet. The United States signed the measure last year through an executive agreement.
