806.02(c) Examination of Specimens of Use in a Multiple-Basis Application 
If the applicant claims use in commerce in addition to another basis, but does not specify which goods/services/classes are covered by which basis, the USPTO may defer examination of the specimens until the applicant identifies the goods/services/classes for which use is claimed. A proper examination of specimens requires consideration of the particular goods/services on or in connection with which the mark is used.
