Iswitch, RIM Patent Dispute over VoIP Ends



On March 9, 2012, Iswitch, LLC (Iswitch) filed a complaint in the United States District Court of Texas against Cincinnati Bell and RIM. Iswitch alleged that they infringe U.S patent no. 7225334 generally directed to voice over IP technology. The complaint sought money damages and all other relief to which the Court may deem the plaintiff be entitled. 

The ‘334 patent entitled Secure method for communicating and providing services on digital networks and implementing architecture was issued on May 29, 2007 and expires[i] by Mar 20, 2021. The patent is currently assigned[ii] to Iswitch (source: MaxVal’s Assignment Database). 

The complaint stated that the defendant RIM manufactures  phones that, when paired with a SIM card, are capable of making VoIP calls on Cincinnati Bell’s network according to the GAN standard, which infringe the method claimed in the ‘334 patent. The accused products are BlackBerry Curve 9300 and BlackBerry Pearl 9100. 

The proceedings were ongoing and on May 28, the parties filed joint motion to dismiss. Following the dismissal filed, the Court rendered its final judgment on Jun 03, ordering the claims and counterclaims asserted in the case be dismissed with prejudice and each party to bear the costs and expenses incurred.
