All forms of intellectual property - copyrights,trademarks,trade secrets and patents - can be transferred in two ways: the property can be temporarily transferred under a license or the property can be permanently transferred by way of an assignment.
Licensing : The key to licensing is the principle of reversion which refers to the fact that you will get the rights back once the license terminates. Typically the reversion occurs upon one of several factors
Separate rights under intellectual property can be licensed separately. A license cannot extend beyond the life of the intellectual property.
Assignments : Assignments are a permanent transfer of the rights. In other words,you are selling the rights to someone else and you will not be getting them back. Assignments are typically made under employment or contractor agreements, when companies acquire the assets of other companies , or when intellectual property is used a security such as when a movie studio secures loan by assigning movie rights in return for a loan.
