My competitors were uncareful enough not to buy out all TLDs, only .com is registered - .info,.us,.org, etc. - are all available for purchase. If I buy those domain names and make a redirect to my website - would this be copyright infringement? If their domain name is smth like masterwidgets? and they do not seem to have registered a trade mark?
you will fall in copyright infringement if that is a trademarked name, otherwise your are free to register not only the name, but the trademark
