What does the Copyright Act of 1976 primarily address?

The Copyright Act of 1976 is primarily focused on establishing the legal framework for copyright protection and rights in the United States. This Act aims to promote the progress of science and useful arts by granting authors and creators exclusive rights to their works for a limited time. It covers a wide range of creative expressions, including literary, musical, and artistic works, and defines the scope of copyright protection, the rights that copyright holders possess, and the limitations on these rights, such as fair use.

By setting these guidelines, the act helps to balance the interests of creators in controlling their work and the public's interest in accessing and using creative content. This makes it crucial for anyone involved in the creation, distribution, or consumption of artistic and intellectual works to understand the implications of copyright law as outlined in the 1976 Act.

The other options address different areas of intellectual property law: patent duration pertains to inventions, trademark regulations deal with brand identifiers, and trade secret laws focus on protecting confidential business information. Thus, they are not relevant contenders for the primary focus of the Copyright Act of 1976.
