Patent Opposition

Patent Opposition

Patent opposition in India can be done, either before the patent is granted, by filing pre-grant opposition by representation, or after the grant of the patent within a year, by filing a post grant opposition. Patent opposition system is a very effective tool that people can use to prevent the grant of infringing patents or patents that do not involve an inventive step. It prevents the existence of frivolous or unnecessary patents in the economy.
