My source believes that scores of internet businesses could also be infringing on the patent portfolio. Think of Tacoda as a test case. If Modavox prevails and its patents are upheld, Modavox could be the next big patent licensor - the Patriot Scientific (PTSC.OB) of internet advertising. And unlike Patriot Scientific, Modavox is actually practicing the technology.
