Patent protection gives you exclusive rights to stop others from making, using, selling, or importing your invention in India. Under the Patents Act, 1970 and the Patents Rules, 2003, eligible inventions that are novel, inventive (non‑obvious), and industrially applicable can be protected by filing a patent application with the Indian Patent Office (IPO).
Filing early secures a priority date. You can start with a Provisional Application (to lock the date while you finalize R&D) and complete it within 12 months by filing a Complete Specification with claims.
International protection can be extended through the PCT (Patent Cooperation Treaty) route or by filing directly in specific countries claiming priority from the Indian filing (within 12 months under the Paris Convention).
