http://biz.yahoo.com/prnews/061026/lath030.html?.v=82The question is, Who besides Pfizer is using their technology?
look at powdermed themselfhttp://www.clinicaltrials.gov/ct/search;jsessionid=BDE4F2D9D84595D01A98467DFA448C47?term=powdermedlook at these trials. basically flu + hepatitis.now with the new situation they might need to pay vical royalties on potential revenues.also, normally upfront and milestone payments (as merck and others did).
You would expect Pfizer to pay Vical rather than litigate an appeal. They made a big investment, paying Vical is a small add on for them, but it will be a big deal for Vical as the DNA Vaccine space heats up.
