In the present study, an attempt has been made to identify the trends of patenting activity in mechanical engineering in India using data from value added databases. It is a first time full data compilation of patent filing and granted data at Indian Patent Office from year 1961 and patent filing data in the different areas of inventions from 1986. Further for this study a separate search was conducted using patent information databases with focus (IPC based) on mechanical engineering sector to understand and identify the companies working in this area. More than 10,000 patent applications and grants exclusively related to mechanical engineering have been considered for analysis. The study indicates focus of research of different organizations/industries in specific areas of mechanical engineering, R&D collaboration between the companies. The paper also addresses various trends and discusses the R&D partnership observed in Indian organizations and foreign organizations. The study further highlights the important directions for future path of R&D.
