NTP, Inc. (NTP) (plaintiff) owned patents disclosing a system and method for integrating email systems with wireless communication networks, enabling users to receive email on handheld mobile devices. NTP sued Research in Motion, Ltd. (RIM) (defendant), claiming RIM’s BlackBerry system infringed the patent’s system and method claims. RIM’s BlackBerry system allowed mobile users to send and receive emails using a handheld device. In each available BlackBerry solution, emails were copied and routed to the BlackBerry “Relay,” located in Canada. The messages were then delivered to the user’s mobile device. RIM moved for summary judgment, contending the geographic requirements for infringement under 35 U.S.C. § 271(a) were not met because the BlackBerry Relay component of the system was located outside of the United States in Canada. The district court disagreed and instructed the jury that the Relay’s location in Canada did not preclude infringement of the patent. The jury found RIM liable for infringement. RIM appealed.
