Patent registration in India is a legal process under the Patents Act, 1970 that grants an inventor exclusive rights over their invention for 20 years. To file a patent, you submit an application to the Indian Patent Office (IPO) — online or in-person — with a provisional or complete specification and pay a government fee starting at just ₹1,600. The process includes patentability search, patent drafting, examination, responding to objections (if any), and final grant — which typically takes 2 to 5 years. DMS Legal World handles the entire patent filing process in India end-to-end, from documentation to grant.
Imagine spending months — or even years — developing a product or process, only to find a competitor selling the exact same thing a few months later. This is not just frustrating; without a registered patent, it is also perfectly legal for them to do so.
Patent registration in India is the most powerful legal tool available to protect your invention. It gives you exclusive, enforceable rights — backed by the government — to manufacture, sell, and license your creation. Nobody else can use it commercially without your permission.
India filed over 65,000 patent applications in 2023–24, a record high fueled by the government’s Startup India and IP awareness initiatives. The competition for protecting innovations is intensifying. If you haven’t secured your patent yet, this guide tells you exactly how to do it — step by step.
What is a Patent?
A patent is a government-granted exclusive right awarded to an inventor in exchange for full public disclosure of their invention. It falls under Intellectual Property (IP) law — alongside trademarks, copyrights, and design registrations.
Once you hold a registered patent, you have the legal authority to:
- Manufacture and sell your invention commercially
- License it to other companies and earn royalties
- Prevent competitors from copying, using, or selling it
- Take legal action (sue for damages) if someone infringes
Who Can Apply for Patent Registration in India?
The patent filing process in India is open to a wide range of applicants under Section 6 of the Patents Act, 1970:
- Individual Inventors — The person who created the invention
- Startups & MSMEs — Eligible for an 80% discount on government fees under the DPIIT Startup India scheme
- Companies & Corporations — Where invention rights are assigned to the employer
- Research Institutions & Universities — For inventions arising from funded research
- Foreign Nationals & Companies — Must maintain an address for service in India
Only the
TRUE INVENTOR
or their legal assignee can apply. If you file a patent for someone else's invention, the patent can be revoked at any time — even after grant.
5 Requirements for a Patent in India
For an invention to qualify for patent registration in India, it must satisfy all five of the following criteria:
What Cannot Be Patented in India? (Section 3 & 4)
- Laws of nature, abstract ideas, mathematical formulas
- Methods of agriculture or horticulture
- Medical, surgical, or diagnostic treatment methods
- Atomic energy-related discoveries
- Traditional or indigenous knowledge (e.g., Ayurvedic remedies)
- Computer programs per se (pure software, without a technical effect)
- Business methods and mental acts
The Turmeric Patent Case (1997): India's IP Landmark
In 1995, the United States Patent and Trademark Office (USPTO) granted a patent to University of Mississippi Medical Center for using turmeric to heal wounds — a practice documented in Indian Ayurvedic texts for centuries.
India's Council of Scientific and Industrial Research (CSIR) challenged this patent, submitting over 40 ancient Sanskrit documents proving the prior art. In 1997, the USPTO revoked the patent — a historic victory for India's traditional knowledge.
This case led directly to the creation of India's Traditional Knowledge Digital Library (TKDL) — a database of 34 million pages of traditional knowledge now used by patent offices worldwide to block false patents.
The lesson for inventors: If India will fight this hard to protect its traditional knowledge, you should be equally serious about protecting your modern invention.
4 Types of Patent Registration in India
Not all patent applications are the same. Choosing the right type for your situation can save significant time and money.
Provisional Patent Application
Filed when your invention is still being developed. Secures your priority date immediately — giving you 12 months to file the complete specification.
✔ Best for: Early-stage inventors & researchers
Complete (Ordinary) Patent
Full application with complete technical specification, claims, and drawings. Can be filed directly or after a provisional application.
✔ Best for: Fully developed inventions ready to market
Convention Patent Application
Filed in India within 12 months of filing in another Paris Convention country. Claims the same priority date as the foreign application.
✔ Best for: Businesses with existing foreign patent filings
PCT National Phase Application
International application (under Patent Cooperation Treaty) entering India’s national phase — must be done within 31 months of priority date.
✔ Best for: Startups targeting 150+ countries simultaneously

How to Apply for Patent Registration in India — Step-by-Step 2026
Here is the complete patent filing process in India as it stands in 2026, from idea to grant:
Invention Disclosure (NDA)
Share full details of your invention with a registered patent agent under a Non-Disclosure Agreement (NDA). Hold nothing back — incomplete disclosure can weaken your application later.
Patentability Search
A comprehensive prior art search across IPO, USPTO, EPO, and WIPO databases to check if your invention is truly novel. A professional search costs approximately ₹10,000–₹20,000.
Patent Drafting
The most critical step. The patent specification must be drafted with both technical accuracy and legal precision. Poor drafting can weaken protection.
⚠ Most Critical StepFiling the Patent Application
Submit Form 1 along with specifications, drawings, and fees to the Indian Patent Office online or at the regional office.
Publication (18 Months)
Your application is published after 18 months. Early publication can be requested by paying an additional fee.
Request for Examination (RFE)
Must be filed within 48 months. Otherwise, the application is treated as withdrawn.
Response to FER
You get 6–12 months to respond to objections. A strong response increases chances of approval.
Patent Grant
Once approved, the patent is granted and published. You gain exclusive rights.
🏁 Final StepAnnual Renewal (Years 3–20)
To keep your patent valid for 20 years, renewal fees must be paid every year from the 3rd year onward.
DPIIT-recognized startups get an 80% REDUCTION on all official patent fees. A complete filing that would cost ₹8,000 for a large entity costs only ₹1,600 for an eligible startup. This is one of the most underutilized benefits available to Indian startups today.
Patent Registration Cost in India 2026 — Full Breakdown
One of the most searched questions about patent registration in India is the cost. Here is the most accurate and up-to-date breakdown for 2026:
Additionally, the 20-year lifetime cost of a patent includes annual renewal fees that escalate over time, totaling approximately ₹5,000–₹40,000+ for large entities over the full term. For individuals, renewal fees are significantly lower.
Documents Required for Patent Registration in India
Before initiating the how to apply for patent in India process, ensure these documents are ready:
How Long is a Patent Valid in India?
A patent granted in India is valid for 20 years from the date of filing — not from the date of grant. This is an important distinction: if your patent took 3 years to grant, you effectively have only 17 years of enforceable protection remaining.
To keep the patent in force throughout the 20-year term, the patent holder must pay annual renewal fees starting from the 3rd year. If fees are not paid, the patent lapses — and once lapsed, the invention enters the public domain and can be used freely by anyone.
Set calendar reminders 3 months before each annual renewal deadline. DMS Legal World provides automatic renewal reminders and handles the renewal filing for all clients.
Patent vs Design vs Trademark vs Copyright — Key Differences
Many inventors and business owners confuse these four types of intellectual property protection. Here is a clear comparison:
If you have an innovative product, you may need both a patent (to protect how it works) and a Design Registration (to protect how it looks). DMS Legal World handles both services under one roof — saving you time and coordination effort.
How a Noida Agri-Tech Startup Turned ₹55,000 Into ₹12 Lakh/Year
In 2021, a small agricultural technology startup based in UP filed a provisional patent application for a low-cost, solar-powered soil testing device that could deliver results in under 5 minutes.
As a DPIIT-recognized startup, they paid a government filing fee of just ₹1,600. Total professional charges came to approximately ₹55,000 for the entire process.
In 2023, after the patent was granted, a large agri-input company approached them. A licensing deal was signed at ₹12 lakh per year — with zero manufacturing responsibility.
The patent converted R&D cost into a passive income stream and helped them raise ₹2.5 crore in seed funding the next year.
6 Costly Patent Mistakes to Avoid in India
Public disclosure before filing: Presenting your invention at a conference, publishing a paper, or posting on social media before filing destroys novelty and disqualifies your application.
Abandoning after provisional filing: Filing a provisional patent and not submitting the complete specification within 12 months leads to automatic abandonment.
DIY patent drafting: Writing your own patent claims without legal expertise often results in weak or invalid protection.
Missing examination request deadline: If Form 18 is not filed within 48 months, the application is treated as withdrawn.
Skipping annual renewal fees: Missing renewal payments causes the patent to lapse and become public domain.
Ignoring international protection: Filing only in India can leave your invention unprotected globally — consider PCT filing.
Important: Using the ® symbol before your trademark is officially registered is a criminal offence under Section 107 of the Trade Marks Act, 1999. It can result in fines and prosecution. Always verify your registration status before using ®.
