The Promoting and Respecting Economically Vital American Innovation Leadership Act, known as the PREVAIL Act, aims to strengthen the U.S. patent system to support inventors and maintain the nation's leadership in innovation. By enhancing patent protections, the Act seeks to encourage investment in new technologies and foster economic growth, particularly in light of increasing foreign competition. The PREVAIL Act introduces several key provisions, including a code of conduct for members of the Patent Trial and Appeal Board to ensure fairness in patent reviews.
