I think someone infringed upon or used my trademark. What should I do now?


The first thing you should do is hire an attorney to send the infringer a cease and desist letter. Many times, this will alert the infringer to the fact that they're infringing on what you consider to be your exclusive mark, and that will stop at that point. If it continues, it will, at a minimum, put them on notice that they are infringing your mark and that continued infringement will result in legal action.
