I think we are witnessing a changing of the guard so to speak with PTSC. I sold last week as well, after over 3years. I bought at .20 and initially sold at $1.40. Then foolishly bought back in again at $2.10 after the second dividend.

I believe the recent purchases are future hopefulls for crossflo and other new PTSC business who are now starting their own long wait for these new companies to bear fruit.

Those of us who were here for the Patents may be heading for the exits a little poorer and hopefully better educated for the (hopefully) next PTSC we run into.

Good luck as I will keep checking back to see what future may be possible for the patents until then I am going to ride Citi Corp for a while.
