Trademark, Patent, and Copyright: What's the difference?

Our Color Vowel® Trademark

The phrase "Color Vowel" is our brand name. To protect our brand (and to prevent others from using our brand in ways that might distort our message or reputation), we have trademarked our brand with the US Patent and Trademark Office. That "®" symbol you see verifies that our trademark is on file with the USPTO.

  • Anytime you refer to Color Vowel® in writing, use the ® symbol.
  • Only licensed partners may display the Color Vowel/ELTS logo. 

Our Color Vowel® Patent

Color Vowel® holds a patent for the audiovisual cueing system embedded in our game, Color it Out!, designed into our app, Blue Canoe®, and formalized in the techniques that comprise the Color Vowel® Approach.

  • A patent license is required of any individual or organization that wishes to integrate our patented system in their published (print or digital) instructional materials.
  • If you plan to publish or distribute your work for use beyond your own classroom, contact us about licensing options.

Our Color Vowel® Copyright

The Color Vowel® Chart is a unique graphic image with key word phrases that provide English learners and teachers with an accurate, efficient way to explore the vowel sounds of English. Karen Taylor and Shirley Thompson, authors of the Color Vowel® Chart, copyrighted their work in order to protect how their life's work is used and represented. ELTS is the exclusive administrator of Color Vowel® trademark and copyright licensing. 

  • Anytime you include an image of the Chart in your own work, you must include attribution
  • If you plan to publish or distribute your work commercially, contact us about licensing options.

Providing attribution: Three practical steps for success

Planning to present at a professional conference? Delivering a talk to your colleagues? Making a short informational video? 

Keep these tips in mind as you spread the word:

  • Say it. The first time you show people the Color Vowel® Chart during a given presentation, acknowledge its name and its authors. Say something like “The Color Vowel Chart, originally created by Karen Taylor and Shirley Thompson in 1999, is a visual organizer for spoken English. Here’s how it works.” Saying something like this is extremely important, as it honors our work and helps others understand that the Color Vowel Chart is copyright protected.

  • Display it. Yes, you can display the Chart in your presentation! Just be sure to include written attribution in your slide show and handouts which is accompanied by explicit verbal credit once again, something like “To learn more about the Color Vowel Chart, please visit ColorVowel.com. They sell Color Vowel teaching materials and provide advanced training on the Color Vowel Chart which I myself have done and highly recommend.” A statement like this makes viewers aware of our Color Vowel training and certification program.

  • Check it. Make sure that “Color Vowel®” and “Color Vowel® Chart” always appear with the ® trademark symbol and are written in full — not as “Vowel Chart” or as “the CVC” (which is easily confused with the widely known “consonant-vowel-consonant” reference to syllable structure). If you need an abbreviated way to refer to “Color Vowel,” you can use “CV” followed by the noun that it modifies; for example, CV Chart, CV Anchor Images, CV Approach.

Attribution: How to acknowledge Color Vowel®

You are welcome to copy/paste these attribution blocks to use in your own work. If you are not sure which version of the Chart to refer to, refer to the 5th Edition, as it is our latest work and the most robust version for the purpose of teaching.

What about training others? Can I do that? 

There's a difference between ‘introducing’ other teachers to Color Vowel® and ‘training’ them in the specific techniques and language awareness that we have developed over the past 20 years and that are unique to our Color Vowel® training courses and workshops.

  • Yes! A presentation is informational and is typically shorter in time (up to 60 minutes). We encourage Color Vowel® certified educators to give presentations at professional conferences and other professional gatherings. Start your Color Vowel® journey with Color Vowel® Basics

  • No. A training (or workshop) is skills-based and outcome-oriented. Any 'presentation' that lasts longer than an hour is probably a training. ELTS is the exclusive Color Vowel® training provider for individuals, schools and organizations. If you wish to train others on the Color Vowel Chart/Approach beyond a brief introduction, you should become a Level 3 certified Color Vowel Licensed Trainer. As a Level 3 Certified and Licensed Trainer, you will be eligible to offer workshops on behalf of ELTS or through your own licensed/accredited organization.
