Make sure you can control every aspect of your domain name. Many domain name registration companies don’t let you make changes to your domains yourself. You have to enter a request via their support systems and then wait days for assistance. Simple things like changing IPS tags and changing name servers should be possible via your control panel. Make sure you get a control panel and check out what the control panel lets you do.
If your purpose in buying a trademarked term as a domain name is to try to confuse people, you’re opening yourself up to having a complaint filed against you and having to give up the domain name. Even if you’re not trying to create confusion, you’re likely to face some legal challenges by buying trademarked terms in your domain name. To be safe, you can search for U.S. trademarks at www.uspto.gov and make sure no one owns a trademark on the name you are considering.
