What is the purpose of PTSC buying back shares? I consider one possibility to be the use of those shares in the purchase of another company, part cash and part shares. Of course shares could be sold later to fund a purchase as well, but then there may be capital gains issues. I am curious to know if any of the companies that bought the license rights from PTSC/TPL have bought shares as well. And why would they?

Just for the record I bought a few more shares this week and that makes 10 million plus that are not out there for sale for a while. Supply and demand, the supply is shrinking. The demand is in need of expanding. I feel that will be coming.
