RE: Staten Patent expiry for Pfizer and AZA partnership before although risky has a lot less dollar value than after a hit. Then basically there will be a bidding war. I like the potential for success there or would have bailed awhile back. As I am all to familiar with the due process I hesitate at the time frame involved but no risk no reward. & IMO with a 52 week low of 1.80 and 8.20 high being in at this price has lots of opportunity .
