In Korea, an employee has the right to obtain reasonable remuneration for a work-for-hire invention when he or she transfers a patent right or the right to obtain a patent, or grants an exclusive licence to the employer in accordance with a contract or service regulation. The employer's expected profit from the work-for-hire invention is considered when determining the reasonable remuneration. A recent Supreme Court opinion provides insight on whether an assignee's expected profit, in addition to an assignor's expected profit, should be considered when determining the remuneration if both the patent for the work-for-hire invention and the relevant business are transferred from the assignor to the assignee.
