RIM's suit, which was filed in the US yesterday, asks for "preliminary and permanent injunctive relief and an award of monetary damages". The Canadian 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 access e-mail and other services, using wireless, directly from Microsoft Exchange e-mail servers. It also announced plans to release a hardware device later this year that would compete with the BlackBerry.
Good Technology filed a peremptory lawsuit in late May, and RIM filed separate lawsuits in June and July, over a wireless e-mail patent, and patent violation. Good Technology had sought a judgment that it did not 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.
