Groups to file suit against AT&T: Public Knowledge and Free Press said Tuesday they will sue AT&T over the company’s decision to disallow iPhone users from using the FaceTime video chat service over cellular networks.

As The Washington Post reported, the groups say AT&T’s actions could be in violation of the Federal Communications Commission’s rules on net neutrality — a claim the carrier has vigorously rejected.

The groups say that disallowing FaceTime runs afoul of net neutrality rules that require carriers to allow apps that compete with its services. AT&T has said this rule only requires that consumers be able to download these apps and does not apply to pre-loaded programs.

The FCC’s rules, more generally, are also under fire from carriers including Verizon Wireless, who would like to see them overturned.

Google Books trial delayed: A federal appeals judge in New York agreed Monday to delay a lawsuit between Google and book authors over the company’s efforts to create a digital library.

The case will be delayed so the court can consider Google’s request to remove class status from the authors in the case. In May, a judge in New York granted the authors class status, saying it would be more effective for the authors to act as a group than to sue Google individually for similar grievances.

Authors say that Google’s project violates their rights to their material, while Google maintains that it’s acting within the limits of copyright law.

Judge denies motion to lift tablet ban: Judge Lucy Koh Monday denied Samsung’s motion to lift an injunction on its Galaxy Tab 10.1, imposed before the company’s high-profile California case with Apple.

Ars Technica reported that Koh denied Samsung’s motion “without prejudice” because the injunction is being appealed in a separate court, the Appeals Court. She did, however, say there is a “substantial issue”to be raised.

A jury found that Samsung did not infringe on the design patents for the iPad — which came as a surprise to many watching the case — prompting Samsung to ask for the sales ban to be dissolved immediately.

ITC taking up Motorola patent suit against Apple: The U.S. International Trade Commission will take up a complaint Motorola filed against Apple, the agency announced Tuesday, which covers Apple iPhones, iPods, iPads and Macs.

The complaint asks for an exclusion order and a cease and desist order, which would stop the import and sales of Apple products.

Motorola originally filed the complaint on Aug. 17. It is the company’s second complaint against Apple before the ITC. The panel remanded that decision to an administrative law judge after clearing Apple on three of four patent charges.
