A skilled copyright attorney can assist a person in successfully applying for a copyright and in bringing a copyright infringement lawsuit. A copyright is generally issued for unique written materials such as a book, poem or article. Authors apply for copyright protection in order to preserve their financial and publication rights accruing from their work. An attorney can assist the author of written work in the application process by helping to distinguish the work from other similar works that may already have copyright protection. A copyright attorney may also be able to bring copyright infringement lawsuits, or defend their client against a copyright infringement lawsuit brought by another party. An attorney who practices in this field is often called an intellectual property attorney.
