IT enabled office process have enabled us to make all information relating to the status of patent application and contents of file, publicly available through the official website. This manual is yet another step to fulfill our commitment to be more efficient and transparent. There has been a demand from the new inventors, patent practitioners and foreign applicants to codify the practices in Indian Patent Office in the form of a manual. A draft manual was published in 2009 in the official website inviting comments and suggestions from stakeholders. Taking into account the comments and suggestions received, that draft has been thoroughly revised to make it more precise and simple. It is our ardent hope that this manual will effectively meet the demands from stakeholders. This manual may be considered as a practical guide for effective prosecution of patent applications in India. However, it does not constitute rule making and hence, does not have the force and effect of law. The manual will be revised from time to time based on interpretations by a Court of Law, statutory amendments and valuable inputs from the stakeholders.
