Develop them on a prize basis or as government IP is one way. Another way is to shelve the start of the patent window along with the drug. If we know it works but it's not needed yet, don't start the countdown to patent expiration until it is needed. The former perhaps lowers costs for the drug more effectively. The latter gives more incentive to the drug companies to keep doing their research.
