Incorrectly claimed small entity status

[cheesepep]

Have application filed as small entity (listed as so in ADS and paid small entity fees), based on what client told me. Client now informs me that it should be large entity instead. Do I just update the entity status to large in PAIR and pay the small entity fee again (two times small entity fee is large entity)?

See MPEP 509.03 paragraph X.

Looks like you can update the status in Private PAIR.  You have to pay the difference between what was already paid and the current large-entity fees.
