GUIDELINES FOR GOODS AND SERVICES NOT FITTING INTO THE ABOVE CLASSES (Trademark Manual of Examining Procedure [TMEP] Section 1401.02):

(1) If a product cannot be classified in accordance with the List of Classes or with the Alphabetical List, the following remarks indicate the criteria to be applied: (a) Finished products are classified, in principle, according to their function or purpose; if that criterion is not provided for in the List of Classes, finished products are classified by analogy with other comparable finished products contained in the Alphabetical List. If none is found, other subsidiary criteria such as that of the material of which the goods are made or the mode of operation are applied. (b) Finished products which are multipurpose composite objects (e.g., clocks incorporating radios) may be classified in all the classes that correspond to each of their functions or intended purposes. If those criteria are not provided in the List of Classes, then other criteria indicated under (a) are to be applied. (c) Raw materials, unworked or semi-worked, are classified, in principle, according to the material of which they consist. (d) Goods intended to form part of another product are, in principle, classified in the same class as that product only in cases where the same type of goods cannot normally be used for another purpose. In all other cases, criterion (a) applies. (e) Where goods, whether finished or not, are classified according to the material of which they are made and where they are made of different materials, such goods are in principle classified according to the material which predominates. (f) Cases adapted to the product they are intended to contain are classified, in principle, in the same class as the product. Services

(1) If a service cannot be classified in accordance with the Alphabetical List, the following remarks indicate the criteria to be applied: (a) Services are classified, in principle, according to the branches of activity specified in the headings of the service classes and their Explanatory Notes or, subsidiarily, by analogy with other comparable services contained in the Alphabetical List. (b) Rental services are classified, in principle, in the same classes as the services provided by means of the rented objects (e.g., Rental of telephones, Cl. 38). (c) Services that provide advice, information or consultation are in principle classified in the same classes as the services that correspond to the subject matter of the advice, information or consultation, e.g., transportation consultancy (Cl. 39), business management consultancy (Cl. 35), financial consultancy (Cl. 36), beauty consultancy (Cl. 44). The rendering of the advice, information or consultancy by electronic means (e.g., telephone, computer) does not affect the classification of these services.
