What does it mean if I infringe on somebody else’s registered trademark right?

A trademark infringement means that a trademark is being used identically or confusingly similarly compared to an already registered trademark by another party. By doing so, the “infringer” is violating the exclusive rights that the current trademark owner is entitled to. The consequence by infringing someone else’s trademark rights can be huge and expensive. In some cases, there is also imprisonment in the scale of penalties.
