Who Owns IN202354?

Last month Delhi Patent Office issued an Indian Patent No. 202354 (the ‘354) to Council of Scientific and Industrial Research (CSIR) for a process for the preparation of fluid catalytic cracking catalyst. The ‘354 patent is classified in the area of catalytic cracking of hydrocarbon oils (C10G 11/00). Accidentally while searching Indian Patent Office official patent database, Patent Circle came across information that Chennai Patent Office too had issued a patent to Roche for carbamic acid derivatives and their use as metabotropic glutamate receptor ligands having same patent number i.e. 202354. That mean we are having substantially two different patented inventions having same patent number in India. In case, if this is because of some typographical error while entering patent data into database then it raises serious questions about the creditability of official patent database which is though under the process of verification and testing. If in case it is not a typographical error, then such incident raises serious doubt about coordination between various offices of Indian Patent Office located in Chennai, Delhi, Kolkata and Mumbai in assigning patent numbers.
