Description: The term ‘Legitimate Use’ generally refers to the use of technology in a manner that complies with legal and ethical standards. This concept is fundamental in the realm of intellectual property, especially concerning the use of works protected by copyright. Legitimate use allows users to utilize protected material without needing to obtain permission from the rights holder, as long as certain conditions are met. These conditions may include the purpose of the use, the nature of the work, the amount used, and the effect of the use on the potential market for the original work. Legitimate use seeks to balance the rights of creators with the public interest, promoting the dissemination of knowledge and culture. In an increasingly digital world, where access to information is immediate and global, legitimate use becomes a crucial tool for fostering innovation and creativity while protecting the work of authors. This concept also applies in other contexts, such as software use, where modification and distribution are allowed under certain conditions, thus promoting a more open and collaborative technological ecosystem.
