USPTO Validates Key Elements of GTL VoIP Patent; GTL Now Positioned to Pursue Injunction and Past Damages of More than $100M in Infringement Suit Against Securus

PTAB Decision allows GTL unobstructed path to pursue patent claims against Securus in Texas Federal Court

Reston, Virginia (PRNewsWire) – May 3, 2016 – Global Tel*Link (GTL) today announced that the U.S. Patent Trial and Appeals Board (PTAB) had completed its review of GTL patent 7,551,732, preserving two key elements protecting GTL’s technology for connecting voice streams to storage devices – an essential component for storing inmate call recordings, which is required in nearly every jail and prison in the U.S. The decision enables GTL to pursue claims now pending in Dallas federal court that Securus Technologies infringes the ‘732, and where experts in the case have estimated Securus could be liable for more than $100M in damages for past use.

“We are pleased that the PTAB decision preserves GTL’s right to protect key components of our technology for safely storing inmate recordings, an almost universal requirement for providing inmate telephone service,” said GTL CEO Brian Oliver. “We intend to move quickly to court to demonstrate to a jury how Securus infringes this patent and is liable for past damages that independent industry experts have valued at more than $100M.”

GTL has never granted a license to the ‘732 or any of the other patents in its lawsuit against Securus. The company is therefore seeking damages and an injunction that, if granted, would require Securus to cease using GTL’s patented technologies on its platforms at all facilities where infringement is occurring. The PTAB preserved two of the ‘732 patent’s claims, while invalidating the remaining claims in its Final Written Decision. GTL is reviewing the decision to determine whether to pursue an appeal of the invalidated claims to the Federal Circuit.

“GTL is committed to continuing its investment in innovation, which is represented by its industry leading patent portfolio,” said Oliver. “We stand by our protection of our investment and our commitment to provide our customers with the highest quality technology.”
