That is, the name/phrase can't be registered with USPTO because it is generic, describes the actual products that the business sales and is widely used in the industry. My thought is that a common law tm is not enforcable under these circumstances., which would not preclude a competitor from using the same or similar name/phrase with an alternate tld extention from doing business handling the same type of products. The exception would be, displaying the competitor's ads w/o permission, of course. What is your opinion?
