Securus Touts PTAB Verification of Two 'Key' Patents

Securus claimed two victories in recent proceedings with the Patent and Trademark Office's Patent Trial and Appeal Board (PTAB) on patent invalidation filings by Global Tel*Link (GTL), Securus said in a news release Wednesday. The PTAB upheld the validity of Securus' patents -- one for a system of controlling inmate access to a telephone carrier network by using VoIP data packets, and another for methods for processing VoIP calls originating within a prison -- that were challenged by GTL, Securus said. Securus CEO Richard Smith said he's "pleased" the PTAB viewed the "key" patents as being valid. GTL didn't comment.
