Can I correct micro entity status errors for multiple applications or patents at once?
No, you cannot correct micro entity status errors for multiple applications or patents in a single submission. The MPEP, citing 37 CFR 1.29(k)(1), states:
Any paper submitted under this paragraph must be limited to the deficiency payment (all fees paid in error) required for a single application or patent. Where more than one application or patent is involved, separate submissions of deficiency payments are required for each application or patent (see § 1.4(b)).
This means you must submit separate deficiency payments and itemizations for each application or patent where micro entity fees were erroneously paid. This requirement ensures clear and accurate processing of fee corrections for each individual case.
