If you are using a particular word, phrase or slogan on a bumper sticker, you can trademark it to prevent any other bumper sticker manufacturers from using it without your permission.
For example, the humorous slogan “SCREW YOU, WE’RE FROM TEXAS” is a registered trademark for bumper stickers. This entitles the owner of the trademark to stop others from using that slogan on bumper stickers without their permission.
Of course, to trademark a bumper sticker, the phrase, logo or slogan must be unique and distinct enough to merit protection. The United States Patent and Trademark Office will reject your application if they determine that your particular phrase is too generic, or too similar to someone else’s prior-registered trademark.
