The cooperation between AMAG and Norgine is just one example of the license. Other recent examples of this strategy are Biogen (NASDAQ:BIIB) and Sangamo Therapeutics (NASDAQ:SGMO), which have entered into a global licensing agreement for the development of drugs for the treatment of neurological diseases, including Alzheimer`s and Parkinson`s. One of the most important elements of a licensing agreement is the financial agreement. Payments made by the licensee to the licensor are generally made in the form of guaranteed minimum payments and royalties on sales. Royalties are typically between 6 and 10 percent, depending on the licensee`s property, experience, and sophistication. .
