The proper term is federally registered service mark.
You can service mark a name and/or logo on the federal level (covering all US states and territories) or you can register a state service mark (which is good just in your state). For instance, Bats, Birds is a service mark of mine. Wildlife Solutions is a service mark of Christian Agnew. Critter Control is a service mark of Critter Control, Inc.
So what does all this mean. Basically, it means that I have the right to protect my business name Bats, Birds, & More, Inc. from any "like" names regardless of spelling. This means if someone tries to name a company that offers wildlife removal or control Bats, Birds, & Beyond, Birds, Bats and other animals, Birds, Bees, and Bats, or Batt & Byrd Wildlife Control, I can use legal means to stop them from using a name similar to mine. I also have protection on Internet meta tags along these lines, but not as much as the company name.
Again, I have legal right to protect a meta tag that uses Bats, Birds, etc. or a close replication of it but I do not have the legal right to protect "We remove bats and birds". When you register a federal service mark for a company name you must sign a release when using common or generic words that you do not own the right to sole usage. For example, if you named your company "Batzee" you can register that name to give you legal protection against anyone else using the word "Batzee", but to register "All County Bat Control" you'd have to sign the release stating you don't have exclusive right to the words "County", "Bat", or "Control" (most likely "All" would not be included as it is too common).
To take this a step farther, if you do a service mark for a logo or acronym, then you can protect items such as look, font usage, and colors. However, just because you have the service mark for a logo it does not give you legal right against someone using the name from the logo.
This is why NWCOA registered the federal service marks for the CWCP and NWCOA logo, CWCP and NWCOA acronym, and Certified Wildlife Control Professional and National Wildlife Control Operators Association to give them the most legal protection as possible but they had to agree that they did not have the exclusive rights to the words "National" "Wildlife" "Control" "Operators" or "Association" in the process.
