Intellectual property refers to any intellectual creation including, but not limited to, literary works, artistic works, inventions, designs, etc. Law exists in order to protect the rights of creators and covers areas of copyright, trademark law, and patents.

Media copyright can be especially complex. A single work may simultaneously exist in multiple formats (e.g. analog, digital, web-based) and may have multiple creators: the composer or writer, the performance director, and the performer, for example. Media (or in fact any work) need not have a copyright symbol in order to be protected by copyright, and therefore it is essential to seek the proper exemptions or permissions to use the material. See our Copyright guide for more information about Fair Use.
