Public health is a branch of science that focuses on preventing disease and injuries in large populations by doing research, educating the public, and creating policies that promote health in all communities. Each person may define public health in a different way. In order to address global health issues, address community-wide health issues, and influence global health policies at both local and global levels, public health is a field of study that encompasses a variety of academic fields, including basic science, commerce, the arts, education, technology, engineering, computer science, pharmacy, and bioscience. Excluding the effects of non-intellectual property barriers like distribution, infrastructure, quality, and medical facilities, the goal of this study is to examine the public health barriers to intellectual property that affect medical access. This study aims to investigate how patent law protects drug accessibility while taking drug prices into consideration.
