How to sue for infringement of digital intellectual property
Understand what constitutes infringement.
Copyright grants you certain exclusive rights in the work you create. You can license other people to do those things for you, but generally others cannot copy or distribute your work without your knowledge.
You have copyright in your work the moment you set it down so that other people can see, read, or hear it. You don't have to mail a copy to yourself or anything like that.
