It is the policy of the IEEE to own the copyright of the technical contributions it publishes. IEEE has moved to an all-electronic copyright submission system. Once you have submitted your final files you will be automatically redirected to the IEEE electronic copyright form where you will be able to complete copyright transfer or select an appropriate license agreement. Hard copy copyright forms are no longer acceptable.
