This masterful analysis of patent law in India, by two of India’s most distinguished jurists, investigates thoroughly the scope of the possible answers to these crucial questions. Recognizing the character of the revolution taking place in patent law globally under the regime of multinational corporations - and India’s central role in its development - Dr. Rao and Dr. Manjula Guru’s analysis focuses on the patenting of substances arising out of advances in biotechnology, genetically engineered products, and computer-related devices. But they do not neglect the practical details of application, registration, and proceedings as constituted under the amended law; in fact, this book is the most detailed and insightful procedural and practice guide to the subject we have. Topics and areas of practice covered include the following: • patent for new use of a known product; • prescribed form of application; • entry in the Register; • powers of the Controller of Patents; • opposition and revocation proceedings; • addition and restoration of lapsed patents; • defences and reliefs in infringement proceedings; • compulsory licensing; • experimental use; • international arrangements for grants of patents simultaneously by several countries; • anti-competitive practices; and • exclusive marketing rights.
