Dispute over a patent deal in Dallas

An article in the Dallas Business Journal includes the text:

--
Dallas inventor Andrew Silver is suing Dallas-based TableTop Media LLC, doing business as Ziosk, for more than $3.5 million, claiming that the technology company breached a patent purchase agreement.
The suit is countering a lawsuit TableTop filed against Silver seven hours prior.
Silver filed the lawsuit March 2 in a District Court of Dallas County claiming that the company based its entire business around the Ziosk restaurant tabletop tablet, which he claims uses his technology. The devices have rolled out to more than 800 Chili's Grill & Bar, 40 Abuelo's restaurants and soon will head to 500 Red Robin Gourmet Burger locations.

There was a deal between Silver and TableTop if Silver's patent issued. The problem: although the patent did issue, the issued claims were not the same as the initially-filed claims.
