Oscar: "This is not a stock that will skyrocket in one day and it should have jumped today but no one on this board, especially including me can come up with a rationale for what causes this. There is a force out there that is forcing the price down for their reasons. I challenge all to come up with who this is and why they are doing this?"

My opinion:  First and foremost THE WARRANTS AREN'T GONE YET!  So this could be just the SOS - S&L selling into the news/volume (however modest).  Nothing has changed or will change till trhe warrants are gone, i.e., when S&L quits selling shares. 

This opinion is arguable, however (even by myself! LOL).  I don't KNOW how many shares S&L currently hold, and thus I don't KNOW how many S&L may need to sell to enable any further warrant conversion and stay under the 10% threshold.  But I will say that assuming S&L are selling shares to enable further conversions, this is good, because it's that many fewer shares that PTSC will need to essentially buy via the warrant buy-back program, preserving the war chest for other things.

In that program, S&L is prohibited from buying shares until the warrants are gone, but they are not prohibited from selling.

And, assuming that S&L has previously sold enough shares, there may be no further need to sell to convert.  They may be just reducing their sizable position (though this too defies logic - why sell now when we appear to be on "the verge"?). 

So, for one reason or the other, I suspect this is S&L causing this effect.  Who else would be selling NOW?

And to answer that, I suspect there are a lot of Longs out there that have loaded up to the hilt and see risk continuing to loom heavy (USPTO/litigation).  I could see where some may be lightening their position, taking a tiddy profit, and holding a core position for the long haul (5 months).

Not much of an answer(s), but you asked for it!

And I KNOW nuttin'!
