The major purpose of copyright law is to protect the rights of creators by giving them exclusive rights to their original works, such as literary, artistic, musical, and other creative works. It aims to encourage the creation of new works by providing creators with the means to control how their works are used, distributed, and reproduced. It also helps ensure that creators can benefit financially from their creations and encourages the dissemination of knowledge and information. Ultimately, copyright law promotes the progress of sciences and arts by protecting the rights of creators and encouraging the creation of new works.
