DALLAS, Dec. 29, 2015 /PRNewswire/ -- Securus Technologies, a leading provider of civil and criminal justice technology solutions for public safety, investigation, corrections and monitoring, announced today that it has had two (2) recent wins from the Patent Trial and Appeal Board (PTAB) related to patent invalidation filings by Global Tel*Link (GTL). Despite GTL's contentions that two (2) Securus patents should be invalidated – the court sided with Securus on these two (2) patents:

  1. U. S. Patent No. 7,529,357 – which discloses a system and method for controlling inmate access to a telephone carrier network using voice over internet protocol data packets exchanged between call processing gateways;
  2. U. S. Patent No. 8,000,269 – which discloses systems and methods for processing voice over internet protocol calls originating within a prison facility that include an unauthorized call activity detector.

"We were pleased that the Patent Trial and Appeal Board viewed these key Securus Patents as being valid and they ruled in Securus' favor," said Richard A. Smith, Chief Executive Officer of Securus Technologies.

"Ultimately, we enjoy significant advantages over GTL in Issued Patents, Pending Patents, In-Force Patents, and our Patent Win-Loss Record – and we have license agreements with most significant carriers in our sector including two (2) previous license agreements that GTL had with Securus over a ten (10) year period," said Smith. "This advantage is material and will last for the foreseeable future given our acquisitions and advanced development efforts. The "Patent Related Metrics" that I referred to are provided below in this Press Release."

"GTL has filed twenty (20) Inter Partes Reviews to attempt to invalidate Securus patents but has only been successful on invalidating two (2) patents to date. My estimate is that they have spent over $10 million in that effort – so not a very good return on that money for them," said Smith. "At that rate, they will have to spend in excess of $200 million attempting to invalidate all of our patents – and that effort clearly will not be successful. A more prudent approach would be to have a license agreement with Securus – that clearly is the best business case for them."
