This chapter provides a comprehensive overview of prognostics and health management (PHM) patents from three aspects: PHM for electrical systems, PHM for mechanical systems, and general PHM methodologies. It deals with the PHM implementation methods, algorithms, and apparatus for specific electrical systems, electronic devices, or pieces of equipment. PHM patents for semiconductor components, computers, and their accessories, such as hard disk drives, memories, and mainboards, account for more than 60% of all PHM patents for electrical systems. Additionally, PHM patents for batteries represent less than a 10% share of patents for electrical systems up to 2015. Nearly all PHM patents for electric motors are based on the measurement of current, since it is closely related to the operating condition of electric motors. PHM patents for electrical devices in automobiles and aircraft are constantly being proposed. Although PHM technologies have matured, PHM patents for networks and communications facilities are currently insufficient.
