Shares of Boston Communications Group ( BCGI) were among technology's losers Monday, falling 63.6% after a jury ordered the company and other co-defendants to pay $128 million in damages to Freedom Wireless in a patent-infringement suit.

The jury found that Boston and other co-defendants infringed on two patents held by Freedom. The jury also found that Boston willfully infringed the patents, which could result in the company paying three times the amount of damages awarded and attorneys' fees. Co-defendants in the case have claimed that Boston is obligated to indemnify them for any damages they incur as a result of any infringement by the company's technology.

Before a final judgment is rendered in the case, a Massachusetts court is expected to act on posttrial motions and hear a separate, nonjury trial regarding an unenforceability defense by Boston and co-defendants. The motions are expected to be filed and the trial is slated to begin on June 7; the trial is expected to take between one and two weeks. If Boston loses the nonjury trial, Freedom could enjoin the company from providing its prepaid wireless and real-time billing service bureau in the U.S.

During the first quarter, sales from prepaid wireless services represented about 90% of Boston's total sales. Were the company unable to provide the prepaid wireless or real-time billing service bureau as currently offered in the U.S., "the company may not be able to continue its ongoing operations or may need to seek protections under the bankruptcy code," Boston warned. Shares traded down $3.06 to $1.75.
