If we assume that they are not buying based on any insider info, then why now?

I would assume that the buying has no relationship to the USPTO. It would be toooooo obvious. I would further assume that there isn't any news with respect to any of the investments that might provide any big permanent boost in the sp. And if there was, that would also be toooooo obvious. So what other info, might have spurred the buying? What's the odds that they all decided at the exact same time that the bottom might be in?

IMHO, Swartz is done selling. I could see that as a very probable rationale for insiders to start buying. If he's done, then any positive news might actually move the pps up and to the right from here on. Opty
