The development of society is directly linked with technology. Technology means the discoveries and development throughout the world which aims at providing people the means of producing goods, rendering services and simply living their lives in comfortable and least consuming ways. The change is very fast and mind-boggling. Invention has to be protected from piracy. It requires adequate and sufficient return as a reward for the R& D efforts. At the same time society should have the benefit of further research and development. Hence, the solution is patent laws. Patent laws are designed to protect not only the interest of the author in his invention, but also to serve a social interest in as much as it encourages and promotes widespread research. This book primarily addresses the various aspects of the Patent system in India along with a detailed comparative study with other countries. It will serve as a good reading for the researchers, inventors, entrepreneurs, IPR lawyers and students by providing them an excellent overview of the important developments in this fast growing field within the past few exciting years along with discussion on the important problems in this area.
