If the patentee entrusts a patent agency during the invalidation procedure, he needs to submit a power of attorney for the invalidation procedure, and state in the power of attorney that the entrusted authority is limited to handling matters related to the invalidation procedure.

In the invalidation procedure, the patentee may entrust a full-range agency within the validity period of the patent right, or may entrust another agency that is not a full-range agency. The authorization procedures, termination and resignation procedures of the patentee can be handled directly at the Reexamination and Invalidation Trial Department, and there is no need to change the bibliographic items at the State Intellectual Property Office. The patentee can entrust multiple patent agencies during the invalidation procedure, but one of the patent agencies must be designated as the recipient.
