from kelly's tip sheet:

Patriot Scientific Corporation –This company seems to be just a shell that makes money by licensing patents. It appears to me that they don’t do anything or provide any value. So what if they have a dividend. If you are looking for dividend yield, you might focus on a larger, financially stable company with the potential to create new products. There are plenty of those in the S&P. Once PTSC’s patents run out or its technology is superseded, what happens to the dividend?

(The last laugh will be on him!)
