Section 8 of the Indian Patent Act (IPA) provides that, if patent applications for the same or a similar invention are filed in other jurisdictions corresponding to a patent application filed in India, the information relating to the filing and prosecution of such patent applications must be furnished to the Indian Patent Office (IPO). Section 8 imposes a duty on applicants who have filed a patent application in India voluntarily to update the IPO with information relating to the filing of their corresponding patent applications and to provide any specific information relating to them, as and when requested by the IPO.
Recently, one of my articles was published in the Journal of Intellectual Property Law & Practice (Oxford University Press). The article discusses s 8, its legislative intent and its interpretation by Indian courts and tribunals, suggesting practice points on compliance with s 8. The article is available here.
