Abstract: Patents are a rich source of technical and commercial information. Patent analysis provides information on the nature and growth of the industry and market leaders. It also helps to develop the technology roadmap, emerging areas of research and company to develop a competitive intelligence tool to maintain a better position of the company in the market place. This paper highlights the results of such a study in the area of micromagnetic sensors. The analysis indicates that 40% of the magnetic sensor patents are granted in the area of micromagnetic sensors, which is an emerging technology area. The researchers of IBM have been most active in the field and have made considerable thrust on patenting in the Magneto-Resistance (MR)/Giant Magneto-Resistance (GMR) sensors. Technological trends indicate the growth of Magneto-Impedance (MI)/Giant Magneto-Impedance (GMI) based sensors due to their promising application, particularly, in medical electronics, automobiles and intelligent transportation system.
