they want to continue to charge $14,000 if you have chrohn's disease. they want to continue to charges $19,000 if of u. you have m.s. they wnts to continue to charge to the 75,000 americans who have limo if a, some $30,000 for a round of zephelin. but if we do create a process, they want to create a permanent patent extension. maybe you give them a 12-year -- after 12 years you allow a generic, unless they slightly change a molecule or a process and you get another 12 years and another 12 years and another 12 years. so in addition to 20 years' worth of patent protection, this athey now have, they want 12 years of market exclusivity which has the exact same effect as patent protection. they get 20 year, then another 12. then when f.d.a. grants a drug market exclusivity, it means that f.d.a. will not approve any generic version of that drug, period. after the first 12 years of market exclusivity is over, the biologics industry want to be able to slightly modify their products, just a slight modification, and they get another 12 years of market exclusivity
