The Patent Litigation Law Review: India
The Indian Patents Act, 1970, recognises product and process patents. The Act allows the applicants to file provisional applications that are followed by non-provisional applications, convention applications under the Paris Convention, national phase application pursuant to Patent Cooperation Treaty (PCT) international application designating India, divisional application and patent of addition application.
The patent of addition applications are the applications that are filed to provide protection to the improvements or modification in the already filed or granted patent. The Patent Rules 2003 were amended in 2016.
