The case was filed in United States District Court for the District of Massachusetts on behalf of purchasers of Microsoft stock between April 18, 2013 and July 18, 2013 (the “Class Period”). The firm is seeking a lead plaintiff for the case. A PDF copy of the complaint is here.

Robbins Geller Rudman & Dowd has been busy filing similar types of class-action suits, as a quick check on its Web site makes clear. (Or, as the August 12 press release more delicately puts it: "Robbins Geller ... has expertise in prosecuting investor class actions and extensive experience in actions involving financial fraud.")

The firm is claiming that Microsoft "issued materially false and misleading statements regarding the Company’s financial performance and its tablet computer, the Surface RT." It is claiming that the company's financial statements for the quarter ending March 31, 2-13 were "materially false and misleading" and that Microsoft officials made misleading positive statements about the Surface RT during the "class period."

Microsoft announced a $900 million Surface RT write-down as part of its Q4 2013 earnings report. Despite that fact, the company is continuing to push ahead with its ARM-based Surface RT platform and is expected to make available new Surface RT accessories and a new Surface RT "release" some time between now and June 30, 2014.

A Microsoft spokesperson said the company had no comment on the class-action suit.
