RIM files another complaint against Good Technology

For the third time in two months, Research In Motion Ltd. (RIM) has filed a lawsuit against Good Technology Inc., this time alleging unfair competition, false advertising, trademark infringement and trademark dilution.

The suit was filed in the U.S. District Court for the District of Delaware Wednesday, and asks for “preliminary and permanent injunctive relief and an award of monetary damages,” RIM said in a statement. The Waterloo, Ontario, company makes the BlackBerry handheld, which allows users to send and receive e-mail.

Good Technology first drew the ire of RIM in May when it announced software that would allow BlackBerry users to wirelessly access e-mail and other services directly from Microsoft Exchange e-mail servers. The Sunnyvale, California, company also announced plans to release a hardware device later this year that would directly compete with the BlackBerry.

Since then, the companies have exchanged legal punches, with Good Technology filing a peremptory lawsuit in late May, and RIM filing separate lawsuits in June and July. Good had sought a judgment that it didn’t infringe upon RIM’s Single Mailbox Integration patent, but RIM alleged just that in its June lawsuit.

A RIM spokesman said the company does not comment on pending litigation. No one from Good Technology was immediately available for comment.
