What are the two possible outcomes if joint inventors disagree about revoking a practitioner's power of attorney?

The correct choice indicates that the revocation of a practitioner's power of attorney must involve the consent of all joint inventors, or it can be executed by one inventor provided they justify their unilateral decision. This aligns with the principle that, in cases involving multiple inventors, decisions affecting the patent application, including the revocation of power of attorney, generally require the agreement of all parties involved to ensure fair representation and authority transfer.

This choice reflects the underlying legal framework that governs patent practices, particularly emphasizing the importance of joint inventor consensus in managing patent prosecution matters. By requiring either all signatures or adequate justification for a single signature, the system aims to protect the rights and interests of all inventors involved. This understanding reinforces the collaborative nature of inventorship in patent law.

Other options may suggest scenarios that do not grant sufficient agency or rights to all inventors or misinterpret the required consensus on such important decisions in the patent process. Thus, adhering to the correct interpretation of joint inventor responsibilities is crucial in this context.
