Research In Motion (RIM), the developer of the BlackBerry mobile e-mail device, and Motorola—the producer of smart phones under the “Q” brand that feature thumb-operated keyboards resembling that of the BlackBerry— filed suit against each other on claims that Motorola refused to honor its pledge to license its technologies to RIM on reasonable terms and that RIM, in turn, willfully infringed several patents held by Motorola. At the core of the dispute is an agreement, signed in 2003, that provides for the cross licensing of various patents owned by each company. In a complaint filed with the U.S. District Court for the Northern District of Texas, RIM accused Motorola of engaging in anticompetitive conduct during recent negotiations to renew the terms of the 2003 pact as evidenced by Motorola’s demands for “exorbitant” royalty payments in exchange for RIM’s continued usage of Motorola patents. Arguing that Motorola violated its agreement to license its technologies on “reasonable” terms, RIM asked the court to prohibit Motorola from taking any measures to block RIM’s usage of the patents in question. Adding that Motorola’s conduct is intended “to injure RIM, a successful competitor and rival,” RIM also claimed that Motorola infringed upon RIM patents that pertain to speech compression and to mobile devices “with a keyboard optimized for use with the thumbs.” Meanwhile, in separate lawsuits filed with the Texas district court and with the U.S. District Court for the District of Delaware, Motorola charged RIM with violating Motorola patents that relate, among other things, to phone number recognition and controlled access to new applications on wireless devices. Motorola, which is also seeking a ruling that it has not infringed upon any RIM patents, declared that RIM’s claims “are entirely without merit.”
