I started a business and came to know the business name uses trademark of another company as
<tradeMark> <English Word>
and created a domain name <tradeMark>inc.net as I wanted to name the business as <tradeMark> Inc but it was taken so I've to register the business as <tradeMark> <another word>
Now I received a letter from a company that says I'm in violation of the domain name because they hold the <tradeMark>.
I'm not in selling of good as they are but in the service business.
Is it a violation and do I've to change the domain name for my website?
i.e. give up <tradeMark>inc.net
and
Will I be able to use <tradeMark><anotherword>.com as it will be same as the business name?
