The question
I'm filing a trademark for my company and want to know the difference between a word and a design mark. For the sake of explaining this let's say my company's name is Random, but the R is styled differently than the rest of the letters, and we occasionally use the styled R by itself. If I were to upload the image of the Random logo, would this protect my company against people using the name Random in association with the goods/services we sell, and would it also protect against the R by itself?
