If there's a site called "bookgiant", which would be a brand, is it legal to make a site called "ebookgiant"? It's also important to note that "bookgiant" is a fairly big site with some money behind them. Note: I just made up a niche and names which follow the same lines as my own issue, so these are not the actual domains I'm asking about. I used this because the site name I want to use also adds the letter "e" at the start, however, the "e" changes the meaning of the word, similar to the example I just used. So it isn't just adding a letter to a brand with no purpose. Need help with this please. Any input from knowledgeable members would be awesome.
