Related Classes

Before registering in Class 42, consider any related or "coordinated" classes under which your mark might be categorized. These include:

  • Business services
  • Insurance and Finance Services (Class 36)
  • Construction and Repair Services (Class 37)
  • Telecommunications Services (Class 38)
  • Shipping and Travel Services (Class 39)
  • Material Treatment Services (Class 40)
  • Education and Entertainment Services (Class 41)
  • Food Services (Class 43)
  • Medical and Vet Services (Class 44)
  • Legal and Security Services (Class 45)

The USPTO considers coordinated classes to be those related to any other class. You may need to file in coordinated classes in addition to Class 42 depending on the trademark.

Why is Trademark Class 42 Important?

Trademark registration is based on a class system due to the varied nature of things that can be trademarked. For each class of goods or services you can register, you're required to pay a separate registration fee.

For instance, if you are a developer applying for a trademark, you may want to register for Classes 9 and 42, which cover both downloadable software and the service the software provides. When doing this, you must pay two fees: one for Class 9 and one for Class 42. You must indicate the correct class when registering your trademark, otherwise, if you enter the wrong class, you'll have to start the application process over again.

Trademark registrations are restricted to the goods and services you already offer or plan to offer, which you must indicate based on the specimens (or proof) you submit or on an intent-to-use basis.

Class 42 is one of the most popular trademark classes for new applications. That means your trademark may face competition or tighter scrutiny. Other common classes include:

Examples of Class 42 Specimens

A specimen is a means of providing proof of your goods or services to the USPTO. Since Class 42 consists of scientific and technological services rather than goods, you need to submit proof of your services on which the trademark is clearly visible. You can do this with:

  • Brochures
  • Copies of your marketing or advertising materials
  • Photographs of your billboards
  • Newspaper or magazine ads
  • Screenshots of your website

Your letterhead or business cards may be used if your services are clearly stated on them. Also, if your service is represented in audio form, such as on radio ads, you can submit a sound file as proof.

The following are unacceptable specimens for Class 42 services:

  • Invoices
  • Packing slips
  • Documents showing the trademark rather than service mark usage, which indicate a connection to goods rather than services
  • Business cards or letterhead only bearing the mark and company name with no reference to services

Common Mistakes

  • Not considering every aspect of your goods or services

In the case of an app developer, you can file both a Class 9 and Class 42 because you're trying to trademark bothsoftware and the service that software provides. However, many developers find it difficult to afford registration formultiple classes. Even so, you should always consider every aspect of your product or service so you can register with the primary class or any relevant classes as you see fit.

  • Registering under the wrong class

Many people choose the wrong class when filing their trademark application. Doing so can cause a delay in receivingyour trademark registration. Be sure to take the time to do your research and classify your trademark correctly. If you're still not sure where your trademark fits, consult a trademark attorney.

  • Filing under the wrong name

This mistake happens more often than you may think. Entrepreneurs often try to register a trademark before completing their corporate paperwork, or they've already completed the required paperwork but register thetrademark in their personal name. These situations result in a voided application, and you must start over again and pay a new application fee.

  • Listing too many goods or services

You want to be detailed about your services when filling out a Class 42 trademark application, but listing too manywill result in denial. The reason for this is that a broad range of services can almost always be broken up into differentclasses, which require additional fees.

Picking the right trademark name is essential. If you choose a bad one, your trademark application will be rejected.

  • Failing to respond to office actions

Office actions are requests by the trademark office for additional information or clarification. You have six months to respond toan office action before your application is abandoned. If you fail to respond on time, you'll have to start the process again.

What Are the Trademark Classes?

The USPTO has relied on the same standardized categories of goods and services since September 1, 1973. Most other nations use this same list, too. The Nice Agreement outlines the categories in the International Trademark Classification System. Also known as the Nice Classification (NCL), it includes 45 general categories, with 34 goods categories and 11 services categories.

Frequently Asked Questions

  • How do I file a Class 42 trademark?

Navigate to the USPTO website and file your trademark application forms online.

  • How do I determine if my trademark falls under Class 9 or Class 42?

Classes 9 and 42 are similar enough that they're often confused. Class 9 refers to electrical and scientific apparatuses. These can include instruments related to surveying, weighing, photography, signaling, checking,lifesaving, teaching, cinematography, and nautical applications. Class 42 denotes services related to some of theseindustries, but the difference is that Class 42 is strictly about services, research, and design, not apparatuses. If you develop an app, for example, the trademark would fall under Class 42.

  • Which services are not included in Class 42?

Class 42 DOES NOT include:

  • Oil and mining extraction
  • Computer file management or word processing services
  • Business evaluations and research
  • Fiscal and financial evaluations
  • Computer hardware installation and repair services
  • Medical treatment services
  • Service provided by those in the medical profession
  • Garden and landscape design
  • Legal services
