What is a Patent?
A patent is an exclusive right granted by a government to an inventor for a limited period, typically 20 years, in exchange for detailed public disclosure of the invention. Patents protect new inventions, processes, or improvements that are novel, non-obvious, and have industrial applicability.
In India, patents are governed by the Patents Act, 1970, and provide the patent holder with the legal right to exclude others from making, using, selling, or importing the patented invention without permission.
Patents can be granted for various types of inventions including:
- New products or devices
- New methods or processes
- New compositions or formulations
- Improvements to existing technologies
Patent Registration Process in India
- 1
Patent Search & Prior Art Analysis
Conduct a thorough search to ensure the invention is novel and not already patented.
Review existing patents, scientific literature, and other publications to identify similar inventions.
- 2
Provisional Application (Optional)
File a provisional application to establish a priority date for your invention.
The provisional application requires less detail and gives the inventor 12 months to file a complete application.
- 3
Complete Application
File a complete specification with detailed description, claims, drawings, and necessary forms.
Must be filed within 12 months of provisional filing, if applicable.
- 4
Publication of Application
The patent application is published in the Official Patent Journal after 18 months from the filing date or priority date.
Early publication can be requested for an additional fee.
- 5
Request for Examination
The applicant must file a Request for Examination (RFE) within 48 months from the filing date or priority date.
This initiates the examination process by the Patent Office.

Addressing Examination Objections
The Patent Office issues an First Examination Report (FER) with objections/requirements.
The applicant must respond to all objections within 6 months (extendable by 3 months).

Grant of Patent
If all objections are cleared, the patent is granted and published in the Official Patent Journal.
The patent is valid for 20 years from the filing date, subject to payment of renewal fees.

Frequently Asked Questions
What is a patent and why should I get one?
A patent is an exclusive right granted by the government for an invention that is new, involves an inventive step, and is capable of industrial application. Patents protect your invention from being made, used, sold, or imported by others without your permission, typically for 20 years. Getting a patent allows you to commercialize your invention exclusively, license it to others for royalties, or sell the patent rights outright.
What types of inventions can be patented in India?
In India, patents can be granted for new products or processes that involve an inventive step and have industrial applicability. This includes technological innovations, machines, devices, methods of manufacturing, chemical compositions, and pharmaceutical formulations. However, mathematical methods, business methods, computer programs per se, algorithms, literary or artistic works, mental acts, and traditional knowledge cannot be patented.
How long does the patent registration process take in India?
The patent registration process in India typically takes 3-5 years from filing to grant. This includes about 18 months for publication, followed by examination (which can take 1-3 years), responding to office actions, and finally grant. However, you can request expedited examination to reduce the timeline to about 1-2 years. Your patent application is confidential for the first 18 months after filing.
What is the difference between provisional and complete patent applications?
A provisional patent application is a preliminary application that establishes a priority date for your invention. It requires only a description of the invention and can be filed with less formal documentation. However, you must file a complete application within 12 months. A complete patent application is more detailed, requiring claims, drawings, and a comprehensive description. The complete application is what gets examined and potentially granted as a patent.
How much does it cost to file a patent in India?
The cost of filing a patent in India varies depending on the complexity of the invention and the type of applicant. For individual inventors or startups, government fees are significantly lower than for large entities. Basic government fees range from ₹1,600 to ₹8,000 for filing, with additional charges for examination, publication, and grant. Professional fees for patent drafting and prosecution typically range from ₹30,000 to ₹150,000 depending on complexity.
