One word missing from a registered trademark is not infringement. Trademark infringement is generally used to make consumers unable to distinguish the difference between a suspected trademark and a normal trademark. But if one word is missing, it should be a major difference and will not cause trademark infringement. Trademark infringement refers to the use of the same or similar trademark on the same or similar goods without the permission of the trademark owner, or other acts that interfere with or hinder the trademark owner from using its registered trademark and damage the legitimate rights and interests of the trademark owner.
