Visto Corp., a push email services provider for many of the largest carriers in the United States and abroad, announced that it has filed a lawsuit against Good Technology for patent infringement. According to the lawsuit, which was filed in the U.S. District Court in the Eastern District of Texas, various Good Technology products, including GoodLink (its push email service) violate patents, held by Visto for the past nine years. This move follows the company's lawsuit against Microsoft Corp. for violating wireless e-mail patents, filed in December last year. Moreover, it comes at the time when one of the biggest Visto's rivals - Research In Motion is threatened by a possible shutdown of its Blackberry mobile e-mail service in the United States in its patent infringement case with NTP. According to Visto Corp.'s Chairman Bogosian, the company wants to offer users a safe alternative if RIM's case has a negative outcome as well as to protect the business from newcomers that do not own any wireless e-mail patents. The lawsuit against Good Technology seeks not only permanent injunction, but monetary damages as well.
