This document discusses patent infringement, including what it is, types of infringement, how to judge infringement, and potential consequences. Patent infringement occurs when someone makes, uses, or sells a patented invention without permission from the patent holder. There are two types of infringement: direct infringement involves directly using the patented invention, while indirect infringement involves supplying parts that can only be used with a patented invention. To determine if infringement occurred, a court will analyze the patent claims and see if they encompass the accused device or process. Potential consequences of infringement include barriers to innovation, damage to economic and legal systems, and financial remedies determined in court cases.
