GTL Countersues Securus for Patent Infringement

GTL alleges Securus uses GTL technology related to wireless services, voice messaging and voice biometrics; Latest action builds upon pending infringement suits implicating Securus’ core SCP Platform and a range of new services


Reston, Virginia (PRNewsWire) – March 21, 2017GTL , an innovation leader in correctional technology and payment services solutions for government, today announced that it had countersued Securus Technologies in Dallas, TX, federal court for infringing three GTL patents covering wireless services, voice messaging, and biometric capabilities. The suit seeks monetary damages and an injunction to prevent Securus’ continued use of the patented technology on its SCP Inmate Telephone system, used by 99.6 percent of all Securus customers, and Securus’ Offender Voice Mail System.

“As the industry leader in technology and innovation, we intend to protect our investment in the services we provide,” said GTL CEO Brian Oliver. “This suit represents a continued commitment to maintain our leadership position in core voice technology as well as new products that we are bringing to market, such as messaging and the use of biometrics to improve security for facilities and consumers,” Oliver said.

In the countersuit just filed, GTL asserted U.S. Patent Nos. 9,509,856; 8,515,031; and 9,521,250. In addition, GTL previously filed complaints in Texas federal court against Securus alleging infringement of four other GTL patents — U.S. Patent Nos. 7,783,021; 7,853,243; 7,551,732 and 7,256,816 — which also implicate the Securus SCP platform and cover services that include call management, voice authentication, VOIP calling, and scheduling video/audio communications for inmates. Securus attempted to invalidate each of these four patents at the Patent Trial and Appeal Board (PTAB) during the past two years, but failed to do so.

“We are only months away from being able to finally show a jury how Securus infringes these four patents, all of which have survived PTAB challenges,” Oliver said.
