WASHINGTON (Reuters) - A patent dispute over prepaid cellular telephones threatens to disrupt service to millions of prepaid wireless customers at several U.S. carriers, including Cingular Wireless.
A federal judge in Boston granted an injunction on Monday against Boston Communications Group Inc., which sells customer management services for prepaid wireless telephones to a number of companies, including Cingular and Alltel Communications Inc.
The court had previously ruled that Boston Communications had infringed on two patents held by Freedom Wireless Inc., and has awarded Freedom Wireless $128 million in damages. Last week, the court added $19.7 million to the award for interest on lost royalties, and said it would explore further damages.
Under the injunction, wireless companies that use the BCGI prepaid wireless services must stop selling them. The companies have 90 days to continue serving current customers, during which they must pay royalties to Freedom Wireless.
