How do I patent an idea or invention in India, and what does it cost?
You can patent an invention, not an idea: it must be new, involve an inventive step and be capable of industrial application, and section 3 of the Patents Act lists what is excluded. File on IP India's e-filing system: Form 1 with a provisional specification in Form 2 to lock the date, the complete specification within 12 months, then a request for examination, which for applications filed since 15 March 2024 must come within 31 months. A startup, individual or small entity pays Rs 1,600 to file and Rs 4,000 for examination, or Rs 8,000 for expedited examination, which startups can ask for on Form 18A; a large company pays Rs 8,000, Rs 20,000 and Rs 60,000. Claim the lower rate with Form 28. A patent agent's drafting fee comes on top and is usually most of the bill. Many software products are better protected by shipping fast than by a patent.
The Patent Office's statement of what can be patented: an invention that is novel, has an inventive step, is capable of industrial application and is not excluded by section 3.
