DisputeSoft was engaged as a testifying expert by the defendant in the matter of Frontline Placement Technologies, Inc. v. CRS, Inc., a patent infringement suit filed on June 18, 2007 in the U.S. District Court for the Eastern District of Pennsylvania.
Frontline claimed that CRS had infringed its patent for a system for performing the automated assignment of substitute teachers.
Frontline’s system, known as “Aesop,” used Interactive Voice Response (IVR) and Internet-based software systems to facilitate the automated posting of worker absences and the scheduling of substitute teachers to fill those absences. Frontline alleged that CRS had infringed its patent by subsequently developing a competing substitute fulfillment system that incorporated many of the features and functions of the Aesop system. CRS countered that the Frontline patent claims at issue were invalid and therefore not entitled to patent protection. CRS further argued that the CRS system did not infringe the claims of Frontline’s patent.
