Microencapsulation is a process by which very tiny particles or droplets of solid or liquid material are coated or surrounded with a continuous film of polymeric material. These micro-capsules have a number of benefits such as converting liquids to solids, providing environmental protection, separating reactive compounds and improved material handling properties. In this article many important techniques for microencapsulation like pan coating, polymerization, salting out, airsuspension coating, hot-melt etc. are described with their patented applications and their patented examples. Microencapsulation technologies are applied in any area of the industry. It can be found in: Cell immobilization, Beverage production, Protection of molecules from other compounds, Drug delivery, Quality and safety in food, agricultural & environmental sectors, pharmaceuticals etc. Patented Microencapsulation techniques are used to increase the duration of action and stability of the drug, as a heat delivery vehicle, in sustain release of water soluble particles, to administration of neuroactive agents
