SEVEN Defends Innovation

Redwood City, Calif. (April 28, 2004) - In a Visto Corporation press release dated April 28, 2004, SEVEN Networks, Inc. was accused of infringing additional patents owned by Visto. Unfortunately, Visto is asserting more of the same old technology that in large part relates to store and forward file replication methods that require storing customer data outside of the firewall on a third party server. As a security precaution, SEVEN's software architecture was designed to avoid the replication of corporate data on a third-party server outside the firewall. In contrast to Visto, SEVEN employs an advanced real-time architecture. SEVEN believes that none of its technology infringes Visto's intellectual property and will continue to mount a vigorous defense.

SEVEN hopes that the wireless community will follow our lead, focus on creating products to benefit customers and not engage in this type of disparaging litigation.

SEVEN stands by the novelty of patent-pending technology, and we will continue to focus our efforts on true innovation and customer service.
