For how many years a Copyright is protected?
The protection period is the author's lifetime and for an additional period of 70 years following his/her death.
If the owner is a legal entity, the duration of protection is 70 years from the date of publicity. As for the works which gets publicized after the death of the owner, the duration of protection is 70 years starting from the date of the death.
If the identity of the owner is not specified, the protection period is 70 years from the date of publicity.
The protection period doesn’t start unless the work gets publicity.
When the protection duration comes to an end, the financial rights granted to the owner end too. Thus, the works that their protection dates are expired can be used freely and without any requirement of permissions from the owner.
