Patent law is the branch of intellectual property law that deals with new inventions. Traditional patents protect tangible scientific inventions, such as circuit boards, car engines, heating coils, or zippers.Once granted, a patent gives the inventors the exclusive right to sell their invention for 20 years. The patents include a varied range of technological resources such as technology for: missile development; aeronautics; combat engineering; arms and ammunition; communication systems; general electronics, to name a few. The companies that can benefit from this shift in the patent policy of DRDO are any state-owned or privately owned defence equipment / material manufacturer including small and medium sized enterprises and even start-ups. This benefit though can only be used under 2 distinct conditions:The company must submit annual commercial reports to DRDO and The company must be equipped to absorb the technology in question, along with infrastructure to manage quality of the production as well as production capability based on the technology.
