When starting a mom and pop operation with aspirations of incorporating in the future, when should one worry about getting a trademark registered? What are the costs associated with doing this? I have noticed that next to some company logos that it will have TM for trademark and others will have the copyright sign. If I were going to start a restaurant called Mcdoogles in my home town as a mom and pop startup and wanted to sell a sandwhich called a big rack
when would I have to worry about protecting the names of each...
