Corrosion affects the quality of the environment, the durability of the infrastructure assets and industrial
equipments. Therefore, it is crucial using corrosion engineering control methods and techniques, in particular safe "green"
e.g. environmental friendly corrosion inhibitors that will extend the life of the infrastructure saving large expenses in
materials equipment and structures. This review presents an analysis of patents on corrosion inhibitors developed for
aqueous systems, steel reinforced concrete, acid pickling operations, oil industry and additives in the formulation of
