Lawsuit Ends against Oracle over Call Queuing System

Case Filed: Apr 14, 2011

Case Closed: Sep 18, 2013

Court: Delaware District Court

Judge: Gregory M. Sleet

Case Summary:
Walker Digital, a Stamford based company creating applications and business solutions sued Oracle, Alston Tascom and Toshiba for unauthorized use of its intellectual properties.  The patents-in-suit included US6222920 and US6487291 both entitled ‘Method and apparatus for value-based queuing of telephone calls’, which were legally issued on Apr 24, 2001 and Nov 26, 2002, respectively. The patents expire[*] by Apr 17, 2017 and are currently assigned[†] to Walker Digital (source: MaxVal’s Assignment Database). Jay S. Walker, chairman of Walker Digital is one of the named inventors of the patents-in-suit.

As per the compliant, the ’291 patent claims enable call centers to rearrange calls in a queue based on prioritization information and the ‘920 patent claims processing a telephone call by determining the economic value of the call and positioning that call within a queue with rank based on the economic value of the call.

Walker Digital alleged that the defendants have used the patented technology of value –based queuing of telephone calls in their offerings, including Tascom Evolution System, Oracle Call Center On Demand and Strata CIX. The suit said, “Walker Digital has suffered and will continue to suffer severe and irreparable harm unless this Court issues a permanent injunction prohibiting defendants from infringing the ’291 and ‘920 patent.”

In 2011, parties including Toshiba, Alston and Oracle filed a stipulation of dismissal. Considering the stipulation filed, the Court granted and ordered that all claims asserted by Walker Digital against defendants be dismissed with prejudice, with each party bearing its own attorney fees, expenses and costs and recently on Sep 18, 2013, the Court declared the case to be officially closed.
