TMEP § 1904.02(c)(i)
When the identification of goods/services is definite in accordance with USPTO policies, the identification is acceptable, regardless of the class assigned. If the goods/services are classified in accordance with the current edition of the Nice Agreement, no further requirements are necessary.
An international registration may encompass goods/services that were classified under an earlier version of the Nice Agreement. If the IB’s classification of goods/services in the §66(a) application is different from the classification currently set forth in the USPTO ID Manual, the examining attorney will not require amendment of the classification. However, the examining attorney should notify the Administrator for Trademark Classification Policy and Practice (Administrator) of the serial number, using the electronic TM Madrid ID/Class Request form. The goods/services cannot be moved to another class identified in the application. 37 C.F.R. §2.85(d).
With respect to acceptable goods/services that appear to be misclassified, if amendment to the identification would identify goods or services in the assigned class, the examining attorney may require an amendment for further specificity to limit the identification to goods/services that are in the class indicated in the international registration.
