Passage: "The concept of 'intellectual property' (IP) has expanded significantly in recent decades, moving beyond traditional patents and copyrights to include new forms such as trade secrets, database rights, and even designs for circuit layouts. This expansion is often justified by the need to incentivize innovation and protect the investments of creators. However, critics argue that overly broad IP protections can stifle creativity, hinder competition, and create monopolies, especially in rapidly evolving technological sectors. For instance, 'patent trolls' acquire patents not to produce goods, but to sue others for infringement, diverting resources from genuine innovation. Furthermore, the global harmonization of IP laws, while aiming for consistency, often favors developed nations and large corporations, potentially disadvantaging developing economies and individual innovators. The debate over IP's scope highlights a fundamental tension between rewarding creators and fostering a vibrant, competitive marketplace."
