Does 2 character or 2 letter .com domains face any copyright issue? because i checked the 9p.com in upsto.gov and found it is already a trademarked company in U.S but at present it is still being auctioned at sedo.com [5days left] .. Owning O2.com can be risky because it is a trademark name of company O2 in UK and US.. Apart from O2 there are many trademarked companies in the world with two characters like 3j,9i, etc...but still 3j.com 9i.com are for sale.. So my question is, Is it healthy to buy a 2 character or 2 letter domains ??
2 letter domain is good i suggest you not to buy any controversial domains unless you have expert lawyer
I guess it's very hard to understand the difference between COPYRIGHT and TRADEMARK. Go to wikipedia and look both up.
