Copyright law mainly protects expressions of ideas in text, art, performance, and recording. Copyright protection automatically arises when a work is created or fixed in some form. Thus, copyright law is distinct from patent law in that no steps need to be taken to obtain copyright protection. In most cases there is little value in registering copyright, although it is beneficial to provide a copyright notice on all works. In Canada, copyright lasts 50 years after the death of the author.

Most copyright disputes arise when one person infringes the copyright of another. Nissen Patent Law has extensive experience protecting the copyright of its clients, and defending its clients against allegations of copyright infringement.
