As the assignor is no longer the owner of the rights, it cannot use the rights without a licence back from the assignee. The assignment of IP can form a standalone IP assignment agreement or may form part of a wider agreement, eg where certain IP rights are assigned as part of a commercial arrangement, project or collaboration. Furthermore, the assignment may be the operative document actually transferring ownership or it may be a follow-up ‘confirmatory’ assignment confirming a transfer which has already happened, eg as part of a business transfer or because the assignor is an employee of the assignee so their IP automatically vests in the assignee.
