Two Minute Trademark Use Primer


Reading Time: 2 minutes

To protect the Moo Duk Kwan® identity and member's exclusive rights for its use, please be sure to incorporate the registered R symbol when using our registered trademarks:

Hwang Kee developed and taught three different martial art systems in his Moo Duk Kwan® school at different points in time:

  • Hwa Soo Do
  • Tang Soo Do - unfortunately in 1985 trademark status was lost for "Tang Soo Do" and it became a generic term "tang soo do."
  • Soo Bahk Do®

Soo Bahk Do® is NOT an ancient martial art system, Soo Bahk Do® is Hwang Kee's interpretation of an ancient martial art system.

Stating or inferring that Soo Bahk Do® is an ancient martial art system undermines its uniqueness and trademark rights.

DO NOT CAPITALIZE "tang soo do" because it is a generic term.

DO NOT place tang soo do in parenthesis next to Soo Bahk Do®.

  • Soo Bahk Do® (tang soo do) 
  • Yes, we are aware it is done that way in some publications, but it was a mistake that should be avoided going forward.

When using Soo Bahk Do® and Moo Duk Kwan® in sentences and paragraphs, running them together and using them in ways that make it unclear which is the art and which is the organization is not a best practice.

It is a much better practice to use language before and after each trademark that makes it clear Soo Bahk Do® refers to the martial art system and Moo Duk Kwan® refers to the organization.

Trademarks should be used as adjectives followed by a non capitalized noun.

For example:

  • Moo Duk Kwan® organization
  • Moo Duk Kwan® schools
  • Moo Duk Kwan® schools provide instruction in the Soo Bahk Do® martial art system
  • Moo Duk Kwan® alumnus
  • Moo Duk Kwan® standards
  • Moo Duk Kwan® requirements
  • Moo Duk Kwan® philosophy
  • Moo Duk Kwan® values
  • Moo Duk Kwan® members   (rather than practitioners  - members clearly belong to an organization)

  • Moo Duk Kwan® history
  • Hwang Kee's Moo Duk Kwan® organization
  • Korean Moo Duk Kwan® schools teach the Soo Bahk Do® martial art system just like USA Moo Duk Kwan® schools.
  • Soo Bahk Do® techniques
  • Soo Bahk Do® training
  • Soo Bahk Do® skills
  • Soo Bahk Do® practitioners   (rather than members  - practitioners engage in a martial art)
  • Soo Bahk Do® master
  • Soo Bahk Do® performance
  • Soo Bahk Do® demonstrations
  • Soo Bahk Do® history
