Introduction
One of the first questions that most inventors, startups, MSMEs, and businesses ask before filing a patent is: “How much will it cost?” In India, patent fees are governed by the Indian Patent Office (IPO) and are payable at different stages—filing, examination, and renewal. The cost is not the same for everyone; it varies depending on whether the applicant is an individual, a startup, or an MSME (all of whom enjoy reduced fees) or a large entity, which pays a higher fee schedule.
To simplify the process, Intepat provides two interactive tools. The Patent Fee Calculator allows you to estimate filing and examination costs, while the Patent Renewal Calculator helps you determine maintenance fees from the third year through the twentieth year of the patent term. Alongside these calculators, you will also find detailed tables and explanations that put the numbers in context, making this one of the most comprehensive guides to understanding patent costs in India.
Patent Fee Calculator – Filing and Examination
Fees
Total Fee:₹ 0
When an application is filed, the applicant must pay a basic filing fee. This fee covers a patent specification of up to thirty pages and up to ten claims. If the application exceeds these limits, an additional charge is levied per extra page and per additional claim. Beyond filing, every applicant must also file a request for examination within forty-eight months of the earliest priority date. Without this step, the application will never move forward in the examination process.
The calculator above gives you an instant estimate of what these official government charges look like for your application, depending on your entity type and the size of your specification.
Filing and Examination Fee Schedule
For transparency, here is a summary of the official IPO fees:
| Particulars | Individuals / Startups / MSMEs | Large Entities |
|---|---|---|
| Filing (up to 30 pages & 10 claims) | ₹1,600 | ₹8,000 |
| Extra page (beyond 30) | ₹160 | ₹800 |
| Extra claim (beyond 10) | ₹320 | ₹1,600 |
| Examination request | ₹4,000 | ₹20,000 |
| Expedited examination (optional) | ₹8,000 | ₹60,000 |
These charges are directly drawn from the official IPO fee schedule. Our calculator ensures you don’t need to crunch these numbers manually.
Patent Renewal Calculator – Annual Maintenance
Once a patent is granted, it must be renewed each year starting from the third year. The renewal fee gradually increases as the patent ages. This is intentional: patents that continue to hold commercial value into later years are expected to justify a higher maintenance cost, while less valuable patents can be allowed to lapse.
Our Renewal Calculator shows you exactly what the official annual maintenance charges look like, helping you plan your IP budget well in advance.
Renewal Fee Schedule (Years 3–20)
| Year | Non-Large Entities | Large Entities |
|---|---|---|
| 3–5 | ₹800 each year | ₹4,000 each year |
| 6–9 | ₹2,000 each year | ₹6,000 each year |
| 10–14 | ₹4,000 each year | ₹12,000 each year |
| 15–20 | ₹8,000 each year | ₹24,000 each year |
Another useful feature of the Indian patent system is that renewal fees may be paid in advance. If you pay for more than three years at once, you receive a 10% discount. This is particularly advantageous for companies with large patent portfolios because it reduces both cost and administrative work.
The Patent Lifecycle and Costs
Looking at patent fees as isolated numbers can be confusing. It helps to think of them as part of a twenty-year lifecycle. At the beginning, the focus is on the filing fee and any additional page or claim charges. This is followed by the examination fee, which must be paid to move the application forward. Once the patent is granted, the attention shifts to annual renewals, which start small but rise significantly in later years. This lifecycle approach allows inventors and businesses to plan budgets and make decisions about which patents to maintain and which to let lapse.
Why Choose Intepat’s Calculators?
What makes these tools different is their completeness. Rather than forcing you to look at separate tables for filing and renewals, Intepat gives you two dedicated calculators, each supported by static reference tables. The data is always aligned with the latest Indian Patent Office fee schedule, and the tools cover the entire lifecycle from filing to the twentieth year. For inventors who need more than just numbers, Intepat also provides expert Patent Services, ensuring your applications are not only filed but strategically managed.
