Ill use fake names to protect privacy... I run a sole proprietorship dba "Central Mass Carpet Cleaners" out of Massachusetts. I received an email from someone from out of state threatening me to change my business name because they have trade marked "Carpet Cleaners".
Do I have to do anything? Our business names have two common words, but they are not the same. On top of that we are operating in different states. Also, he is an Inc. and I am a sole proprietorship.
Hope to hear from somebody asap.
Thank you
