A putative class action in federal court in Newark charges that business research provider Dun & Bradstreet planted false information in companies’ credit reports in order to market a subsidiary credit repair service.

The suit was brought on behalf of New Jersey small businesses that purchased CreditBuilder, a product that enables them to monitor and dispute entries on their credit reports. It is sold by Dun & Bradstreet Credibility Corp. (DBCC), a D&B affiliate based in Malibu, Calif.
