BioSante has retained all rights under the BioSante-licensed patents to the transdermal delivery of triple hormone contraceptives. �We are excited to sign this hormone oral contraceptive license agreement,� said Stephen M. Simes, president & CEO of BioSante. �We have known Herjan Coelingh Bennink, the founder and CEO of Pantarhei for many years and we believe this is an excellent company to develop further our issued patents for oral contraceptive uses.
