Meaning
Agency relationship where the agent possesses a legal or equitable stake in the subject matter of the power. A power coupled with an interest is a specific type of authority that is not terminated by the death or the revocation of the principal. This structure is often used in security agreements and intellectual property assignments to protect the rights of a lender or an assignee.
It ensures that the power remains effective as long as the interest exists.
Irrevocability Condition
The defining characteristic of a power coupled with an interest is that the principal cannot unilaterally take back the authority granted to the agent. This is because the power is given as a security for a debt or the performance of a duty. If an inventor grants a company the power to sign patent documents to secure an assignment, that power is irrevocable.
This provides a guarantee that the company can protect its investment regardless of the future actions of the inventor.
Termination Event
A power coupled with an interest only ends when the underlying interest is satisfied or the time period specified in the agreement expires. Unlike a standard power of attorney, it does not end if the principal becomes mentally incompetent. This stability is necessary in complex commercial transactions where the agent must have the certainty of control.
The power survives as long as the economic justification for it remains in place.
Security Interest
The existence of a valid security interest is what distinguishes a power coupled with an interest from a mere agency. The agent must have a stake in the property itself, not just a right to be paid for their services. In the hardware industry, this often involves a right to the patent title or a portion of the royalties.
This connection ensures that the agent is acting to protect their own assets as well as those of the principal.
