It might seem axiomatic that whenever you develop a new product or service you ought to immediately register a trademark or servicemark to ensure marketplace protection. And I’m not talking about trademarking “That’s Hot” or “You’re Fired!” I’m talking about real, useful stuff. Like Oxyclean.® Or Chia Pet.®
(Fun fact of the day: you can only use the ® symbol if your mark is registered with the USPTO. Otherwise you are stuck using the ™ symbol, which is just a claim of ownership over a mark.)
Most of the time, promptly registering a trademark is a good idea — not only does it help you establish rights in your own mark, it gives you early warning if you’re going to wind up in a dispute (and ample opportunity to change your mark before you invest too much time, money, and heart into it). But not always. For a good example of the latter situation, just look at the current dispute between ZeniMax Media, the publisher of a series of role-playing games called The Elder Scrolls and forthcoming game entitled The Elder Scrolls V: Skyrim, and Mojang, creator of the popular game Minecraft, and forthcoming game entitled, Scrolls.
