In organizing its registry of trademarks, the U.S. Patent and Trademark Office (PTO) divides marks into 45 different "classes" of products or services. Class 1 includes chemical products used in industry, science, and agriculture, including those that go to the making of products belonging to other classes.
Why Use the Trademark Class System?
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, for instance, you use 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.
The classes you can register under are restricted to those 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.
When Would a Product Qualify as Class 1?
You would register your trademark within Class 1 if you were registering any of these types of goods:
- chemicals used in industry, science and photography, as well as in agriculture, horticulture and forestry
- unprocessed artificial resins, unprocessed plastics; manures
- fire extinguishing compositions
- tempering and soldering preparations
- chemical substances for preserving foodstuffs, or
- tanning substances; adhesives used in industry.
For example, if you were registering a trademark for compost, or for certain additives for the food industry, you would register it in Class 1. For a complete listing of all goods in Class 1, see below.
Examples of trademarks in Class 1 include CYCLOPOL (Chemicals), CLOUD-CLONE (Biochemical reagents), SEPTIC MAGIC (Biodegradable waste digestant), and ISOFLASK (sampling kit for water).
You would not use Class 1 if you were registering:
- natural resins (Class 2)
- chemical products for use in medical science (Class 5)
- fungicides, herbicides and preparations for destroying vermin (Class 5)
- adhesives for stationery or household purposes (Class 16)
- salt for preserving foodstuffs (Class 30), or
- straw mulch (Class 31).
Related (Coordinated) Classes
If you are unsure whether you should register in Class 1, you might also consider the following “coordinated” classes: Class 5 - Pharmaceuticals, Class 17 - Rubber Products, Class 35 - Advertising and Business Services, Class 42 - Science and Technology Services, and Class 44 - Medical and Vet Services. A coordinated class is one that is related to another class, usually because the PTO has determined that applicants filing within Class 1 often file in the coordinated classes, too.
Specimens for Class 1
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 1 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 affixation. 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 1 goods is an acceptable specimen. For example, gasoline pumps are normal containers or “packaging” for gasoline.
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
