Patent Fees Calculator India 2025 – Calculate Filing, Renewal & Maintenance Costs for Bangalore and Chennai

Introduction

One of the first questions inventors, startups, MSMEs, and businesses ask before filing a patent is:

“How much will a patent cost in India?”

Patent fees in India including patent filing fees, examination fees, and patent renewal fees are governed by the

Indian Patent Office (IPO)

and are payable at different stages of the process. These

patent costs in India

vary based on the applicant category, with individuals, startups, and MSMEs receiving significant fee reductions, while large entities pay as per the standard IPO fee schedule.

To simplify the process,

Intepat

offers two interactive tools: the

Patent Fees Calculator

, which helps you

estimate patent filing fees and examination charges, and the Patent Renewal Calculator

, which calculates annual renewal fees from the 3rd to the 20th year. This page also includes detailed tables, renewal schedules, and explanations — making it one of the most comprehensive guides to understanding

patent fees, patent filing charges, and patent renewal fees in India and Bangalore

, as well as other major cities like Chennai.

When a

patent application is filed in India

, the applicant must pay a

basic patent filing fee

prescribed by the

Indian Patent Office (IPO)

. This base fee covers a patent specification of up to thirty pages and up to ten claims. If the specification exceeds these limits,

additional charges apply per extra page or claim

.

Beyond filing, every applicant is required to

file a Request for Examination (RFE)

within forty-eight months of the earliest priority date. This process incurs a separate

patent examination fee

, which varies depending on whether the applicant is an

individual, startup, MSME, or large entity

. Without this examination request, the patent application will not proceed to substantive examination.

The

Intepat Patent Fee Calculator

provides an instant estimate of

patent filing and examination fees in India

, including the

official IPO government charges

for your specific

entity type and document size

. Whether you are based in

Bangalore, Chennai, or elsewhere in India

, this calculator helps you understand your

expected patent filing cost

quickly and accurately.

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 Fees and Annual Maintenance in India

Already Paid?

Once a

patent is granted in India

, it must be renewed every year starting from the

third year until the twentieth year

of its term. The

patent renewal fees

— also known as

annual maintenance fees

— gradually increase as the patent ages. This structure, set by the

Indian Patent Office (IPO)

, ensures that only patents with ongoing

commercial value

are maintained, while less valuable ones may be allowed to lapse.

The

Intepat Patent Renewal Calculator

gives you an instant breakdown of

official patent renewal fees in India

, including the

annual maintenance cost

for each year from

Year 3 to Year 20

. It helps you estimate your

total renewal cost

in advance and plan your

IP budget

efficiently — whether you’re an

individual, startup, MSME, or company

based in

Bangalore, Chennai, or anywhere in India

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 Associated Costs in India

Looking at

patent fees in India

as isolated numbers can be confusing. It’s easier to understand them as part of a complete

twenty-year patent lifecycle

. In the early stages, the key expenses are the

patent filing fees

and any additional page or claim charges. This is followed by the

patent examination fee

, which must be paid to move the application into active review by the

Indian Patent Office (IPO)

.

Once a

patent is granted

, attention shifts to

annual renewal or maintenance fees

, which start low but gradually increase in later years. This progressive fee structure encourages inventors and companies to maintain only patents that continue to hold

commercial value

. By understanding this full

patent cost lifecycle

inventors, startups, and businesses in Bangalore, Chennai, and across India

can plan IP budgets effectively and make informed decisions about which patents to renew or allow to lapse.

Frequently Asked Questions

Do Individuals, Startups, and MSMEs all pay the same fees?

Yes. The IPO groups these applicants together under the “non-large entity” category. They all pay the reduced fee schedule, which is significantly lower than the charges for large entities.

Are attorney or professional fees included in the calculators?

No. The calculators are designed to reflect only the official government fees. Professional fees for drafting, filing, and prosecution are separate and vary depending on the complexity of the invention. For a complete cost estimate including professional support, you may contact us.

When do renewal fees start?

Renewal fees become payable from the third year onwards. The first two years after filing do not require renewal payments.

Can renewal fees be paid in advance?

Yes, and doing so comes with a benefit. If renewal fees are paid for more than three years in one installment, the IPO grants a 10% discount. Many applicants prefer this option as it lowers cost and reduces the risk of unintentional lapse.

What happens if renewal fees are not paid?

If the renewal fee is not paid on time, the patent will lapse. A grace period of six months is available with late fees. Restoration may be possible within eighteen months from the lapse date, but it requires a formal request, additional fees, and justification, and the Patent Office has discretion to accept or reject the restoration.

Why do renewal fees increase over time?

The progressive increase is a policy decision. It ensures that only patents with genuine commercial or strategic value are maintained into later years, while less relevant ones naturally expire. This balances the patent system by keeping the register free of unused monopolies.
