GTL’s Landmark Patent Challenge Targets Securus Technologies’ IP Portfolio

Global Tel*Link Files 10 Petitions Under the America Invents Act Challenging the Validity of Securus Patents

Reston, Virginia (PRNewswire) –May 19, 2015 – Global Tel*Link Corporation (GTL) today announced that it had filed 10 more petitions at the Patent Trial and Appeal Board (PTAB) as part of an expanding effort to invalidate the core of Securus Technologies Inc.’s patent portfolio.

The petitions – 7 inter partes reviews, 2 post-grant reviews and 1 covered business method review – target a cross-section of the Securus portfolio, including patents on video calling, payment services, messaging, investigative solutions and inmate telephone services, among others. In its filings, GTL alleges that the Securus patents mimic available consumer products, like Apple’s FaceTime, and a range of other technology that was well known long before Securus’ patent applications were filed.

“GTL views these patents as roadblocks to free and fair competition, and we are challenging them to demonstrate to the marketplace that Securus is not the innovator it claims to be,” said GTL CEO Brian Oliver. “We believe that this latest action will, once and for all, bulldoze the patent toll booth that Securus has used to impose what amounts to a cost-of-doing-business tax on the industry. GTL seeks to expose these patents for what they are – a collection of ideas and inventions that others thought of first and which Securus wrongly claimed as their own.”

Securus has filed at least 12 lawsuits against 19 industry competitors over the last decade, often cornering smaller companies into settlements to avoid the high costs of litigation.

In its petitions to the PTAB, GTL has asserted that Securus inflated its intellectual property portfolio by filing duplicative patents with minor changes, obtained patents covering a wide range of technologies already in the public domain and patented by other companies, and secured patents without inventing any new technology.

GTL challenged 8 Securus patents at the PTAB last year. In those cases, the PTAB has already found that there is a reasonable likelihood that GTL will prevail in proving all of the 146 claims in those patents are invalid. The Board has instituted trial against all 8 patents, including against the Securus’ “crown jewel” ‘167 centralized call processing patent, which GTL alleges was approved on the basis of misleading statements by Securus to the patent examiner.

“GTL is determined to end Securus’ legacy of patent litigation,” Oliver said. “We are committed to exposing their baseless claims in court, to end their harassing lawsuits, and to stop the fear tactics that have been a plague on this industry for a decade.”
In these new filings before the PTAB, GTL alleges that 9 additional Securus patents and 209 additional patent claims are invalid. The patents that GTL has challenged include:

• A patent that offers telephone rate discounts to inmates for good behavior. (Patent No. 6,636,591). GTL says that this patent did not include any new technological innovation.
• A patent that describes switching from a voice call to a video call. (Patent No. 8,929,525). GTL alleges that Securus did not invent the equivalent of FaceTime for inmates.
• A patent that describes a resource allocation method that GTL maintains has been a fundamental part of computer operating systems since at least 1991. (Patent No. 7,324,637).
