4. List 3 things that are not protected by copyright law.

Copyright law protects original works of authorship, such as literary, dramatic, musical, and artistic works. However, there are certain things that are not protected by copyright law. Here are three examples:1. Ideas, procedures, processes, systems, methods of operation, concepts, principles, or discoveries: Copyright law does not protect the underlying ideas or concepts behind a work. For example, a book about the concept of democracy is not protected by copyright, but the specific words and sentences used to express that concept in the book are.2. Titles, names, short phrases, and slogans: Short phrases and slogans, such as the title of a book or the tagline of a company, are not protected by copyright law. However, if a short phrase or slogan is used in a creative and original way, it may be protected as a trademark.3. Facts and news: Facts and news are not protected by copyright law. For example, a newspaper report about a recent event is not protected by copyright, but the specific words and sentences used to describe the event in the report may be protected.It is important to note that while copyright law does not protect these things, there may be other legal protections that apply, such as trademarks or patents.
