USPTO May Not Impose Additional Drawing Requirements During National Stage Examination Beyond PCT Rule 11
Note:
The USPTO is prohibited from requiring additional drawing specifications during national stage examination beyond what is required by the Patent Cooperation Treaty, but can request new drawings if published ones do not meet all PCT requirements.

The USPTO may not impose drawing requirements during the examination of a national stage application beyond those imposed by the Patent Cooperation Treaty (e.g., PCT Rule 11). However, the examiner does have the authority to require new drawings if the drawings were published without meeting all requirements under the PCT for drawings.
