Implied licence

An implied licence to use a copyright work might arise when there is nothing in writing granting you a licence and you have not even agreed a licence verbally with the copyright owner.  However it is always better to ensure that any agreement about a licence is recorded in some way.

You will only be able to argue that you have an implied licence where all the circumstances suggest that the copyright owner expected you to use his or her copyright material in the way you are going to use it, even though this was never discussed and has not been written down anywhere.
