FORT WAYNE, Ind. (AP) _ A third lawsuit seeking class action status has been filed against a Fort Wayne-based medical software company over a data breach involving patient information.

The Journal Gazette reports the lawsuit from Ryan Pool against Medical Informatics Engineering was filed Wednesday in federal court. Pool alleges that his data was compromised through a hospital south of Indianapolis.

The company has reported that the hack of its networks earlier this year has exposed private information of 3.9 million people nationwide. The information includes patients' names, birth dates, addresses and Social Security numbers.

The company notified the FBI about the hack in May, and began issuing letters to patients in mid-July.

Two other lawsuits against the company were filed in recent weeks. All three lawsuits accuse the company of negligence.
