Trademark Class 6: Common Metals

Trademark Class 6 includes mainly unwrought and partly wrought common metals as well as simple products made of them.

The U.S. Patent and Trademark Office (PTO), the federal agency that oversees the registration of federal trademarks, divides marks into 45 different "classes" of products or services. The purpose of these classes is to allow different types of businesses to register their trademarks into categories most related to their industry or business. Class 6 includes mainly unwrought and partly wrought common metals as well as simple products made of them. See below for a complete listing of all goods in Class 6.

For more information about trademarks and federal registration, see Nolo's articles on Trademark.

Examples of Trademarks in Class 6

Many marks fall into Class 6. Consider, for example: ELITE (fencing systems), BLACK & DECKER (ladders), LIGHTFOOT (fasteners), and HANDYTUBE (stainless steel tubing).


You would not use Class 6 if you were registering:

Related or "Coordinated" Classes

A coordinated class is one that is related to another class, usually because the PTO has determined that applicants filing within Class 6 often file in the coordinated classes, too. If you are not sure whether you should register in Class 6, you might also have a look at the following “coordinated” classes: Class 11 - Appliances, Class 17 - Rubber Products, Class 19 - Building Materials. Class 20 - Furniture, Class 35 - Advertising and Business Services, Class 37 - Construction and Repair Services, Class 40 - Material Treatment Services, and Class 42 - Science and Technology Services.

Remember, trademark registration is based on a class system. For each class of goods or services that you register, you must pay a separate registration fee. So if you apply for a trademark for posters (Class 16) and shirts (Class 25), you must pay two fees. You must indicate the correct class at the time you are registering a trademark. If you list the incorrect class, you must start the application process over.

Your registrations are restricted to those classes that encompass the goods or services you are already offering (as shown by the specimens you submit) or that you plan to offer (if you are registering on an intent-to-use basis). You may also need information about the class number in order to narrow a search of the PTO's trademark database.

Specimens for Class 6

If the mark is used in commerce, you must furnish a specimen of the mark as consumers see it. The specimen must show the mark as used on or in connection with the goods in commerce. A trademark specimen should be a label, tag, or container for the goods, or a display associated with the goods. A photocopy or other reproduction of a specimen of the mark as actually used on or in connection with the goods is acceptable.

In most cases, where the trademark is applied to the goods or the containers for the goods in Class 6 by means of labels, a label is an acceptable specimen. Shipping or mailing labels may be accepted if they are affixed to the goods or to the containers for the goods and if proper trademark usage is shown. They are not acceptable if the mark as shown is merely used as a trade name and not as a trademark. An example of this is the use of the term solely as a return address.

Stamping a trademark on the goods, on the container, or on tags or labels attached to the goods or containers, is a proper method of trademark affixing. The trademark may be imprinted in the body of the goods, as with metal stamping; it may be applied by a rubber stamp; or it may be inked on by using a stencil or template. When a trademark is used in this manner, photographs or facsimiles showing the actual stamping or stenciling are acceptable as specimens.

The terminology “applied to the containers for the goods” means applied to any type of commercial packaging that is normal for the particular goods as they move in trade. Thus, a showing of the trademark on the normal commercial package for the particular Class 6 goods is an acceptable specimen. A specimen showing use of the trademark on a vehicle in which the goods are marketed to the relevant purchasers may constitute use of the mark on a container for the goods, if this is the normal mode of use of a mark for the particular goods.
