Copyright infringement occurs when a person copies, publishes or otherwise uses information without the consent of a person who holds a legal right to that material. This is a legal term that refers to the unauthorized use, especially where the person uses the protected information as though it were their own. Copyright infringement can sometimes create a very public legal trial, such as where a newspaper is accused of plagiarism or when the claim relates to a famous book. Attorneys who practice in the field are often trial lawyers primarily. However, some attorneys are skilled both in helping clients apply for legal protection and in bringing or defending against lawsuits.
