If you really have held PTSC for 13 years, and never acted to take a profit in very late 1999 or very early 2000, when PTSC was over $4/share, then who do you have to blame? Ditto early 2006.

Also, get your facts straight re: patent expiration and the ability to obtain royalties beyond that date (3 or 6 years, if I understand correctly - Milestone?) for infringement after notification and prior to expiration.

Also note what was recently posted about the '584. I don't know that it's verified as correct, but I read that the amended '584 is like a new patent, meaning it's got a long, full life ahead. BTW, it amazes me that this got no further discussion, at all. Bogus? Real? Help! Who posted it? Quoting whom? I believe this fell out of the AMS.
