What is the duration of a power to inspect granted by an applicant or inventor?

The duration of a power to inspect granted by an applicant or inventor is generally ongoing until explicitly rescinded. According to MPEP 104:

“An unrestricted power to inspect given by an applicant or inventor is, under existing practice, recognized as in effect until and unless rescinded.”

This means that once granted, a power to inspect remains valid indefinitely unless the grantor takes action to revoke it. However, it’s important to note that this applies to unrestricted powers to inspect granted by applicants or inventors, and different rules may apply to other types of authorizations or parties.
