Cease and Desist

Well, apparently the name "Artineering" has been used by someone commercially, therefore I cannot use the name anymore. Here's the official warning I got just recently:

"My client, Lance Dehne', business owner of ARTineering since 1985 and trademark holder of ARTineering requests that you immediately cease and desist using his Company name."

I wonder, since I'm not using the name for commercial purposes nor for profit, and I don't capitalize the word "Art" in my "Artineering", I don't understand why it is a problem. "cease and desist"?

In any case, I'm honoring the request, and I hope everybody's happy now.

For the owner of ARTineering, I apologize for using the name of your business without your consent and without checking that it was a registered name. I did not mean to cause any disruption nor any confusion to your business and your clients; I used the name since it reflects my interest in both the area of engineering and art. I'm actually happy that there actually IS an artistic engineer out there. I hope there won't be anymore problem now.

Best regards.
