Potential: Patriot and TPL partnered to focus on patent revenue in 2005. Around the same time, PTSC ceased its research and development operations.

There was lots of potential then. But It's far more difficult to make a case to investors now based on the "potential" value of PTSC when we're approaching 9 years of actuals.

We may be at a turning point but we've perceived turning points before which seemed close at hand. Don't hold your breath. Hold on to your stock - there's no reason not to.
