In 1856, the first patent in India was granted for a punkah pulling machine, and the inventor had to walk his drawings into an office in Calcutta. Today, patent e filing lets you do the same job from your desk in a single sitting.
Patent e filing means submitting your patent application to the Indian Patent Office through its online portal instead of on paper. You sign your documents electronically rather than by hand. The portal is open all day, every day, and it gives you an application number the moment your payment goes through.
This guide explains who has to file online, what you need before you start, how the process works, what it costs, and which deadlines follow. Everything below relates to applications filed in India under the Patents Act 1970 and the Patents Rules 2003.
What Is Patent E Filing in India?
The Indian Patent Office launched online patent filing in 2007. In 2012, it upgraded the system into a comprehensive service that handles new applications and later documents in the same place.
When you register on the portal, you get your own account and folder inside the office’s system. Your saved details carry over, so a second application takes less time than your first.
The portal is one central system. You do not choose a city when you file online, even though a particular branch office will handle your application afterwards.
Who Must E-File a Patent Application?
This is the point most guides get wrong, so it is worth being precise.
Registered patent agents have no choice. Rule 6(1A) of the Patents Rules 2003 states that a patent agent shall file all documents only by electronic transmission, duly authenticated. If an agent acts for you, your application goes online by law.
Everyone else may choose. Rule 6(1) still allows you to deliver documents by hand, by post, or electronically. An individual inventor, a startup, a small entity or a company filing without an agent may lawfully file on paper.
The catch is cost. Physical filing carries a 10% additional fee under the proviso to Rule 7(1). So you keep the choice, but you pay for it.

What You Need Before You Start Patent E Filing
A Digital Signature Certificate or e-Sign
You must be able to sign electronically. There are two routes.
A Digital Signature Certificate is issued by a licensed certifying agency. The portal accepts a Class II or Class III certificate without encryption. Arrange this early, because it comes from outside the portal and takes time.
e-Sign is the alternative. It works through your Aadhaar or PAN and is generated on the spot. It needs no hardware token, which makes it the simpler option for a first-time applicant.
The Forms That Apply to You
Not every application needs every form. Much depends on your application type and your applicant category. The table below covers the common ones and, more usefully, when each is due.
Form | Purpose | Deadline | If you miss it |
Form 1 | Application for grant of patent | At filing | No application exists |
Form 2 | Provisional or complete specification | At filing | No application exists |
Form 3 | Statement and undertaking on foreign applications (Section 8) | Within six months of filing | Ongoing disclosure duty breached |
Form 5 | Declaration of inventorship | With the complete specification | One month’s grace with the Controller’s leave, on Form 4 |
Form 26 | Power of attorney authorising an agent | Within three months | Rule 135(1) halts further processing |
Form 28 | Declaration of startup, small entity or educational institution status | With every fee-bearing document claiming that rate | Lower fee slab refused |
Small entity status depends on the investment thresholds in Section 7(1) of the MSME Development Act 2006. It is not a matter of how small your business feels.
Patent E Filing Process: Step-by-Step
Sign up, then log in –
The IP India patent e-filing portal asks for a user name, password and captcha. First-time users register through the sign-up link on the same screen. That login page also carries the links you will want early on: where to procure electronic signatures, how to map them to your account, and the user guide.
Pick the right form from the dashboard –
Once inside, the left-hand menu lists everything the portal accepts — New Application (Form 1), PCT National Phase Application (Form 1), Form 2, Form 9, Form 18, Form 28, Form 30, renewals, replies to examination reports, and petitions. For a fresh Indian filing, choose New Application.
Set the basics at the top of Form 1 –
You select the jurisdiction, the type of application, and the type of specification, provisional or complete. Then you enter the counts: pages of description, number of claims and their page count, pages of abstract, pages and number of drawings, sequence listing pages, and number of priorities. Take care here. These figures are what the portal uses to calculate your fee.
Fill in the title and address for service –
Title of invention, address in India, state, mobile number, telephone, fax and email. Every communication from the office goes to the email address you enter, so use one you actually monitor.
Type in the abstract, description and claims in full –
This one surprises most first-time applicants. Uploading your specification is not enough — the portal requires the full text of the abstract, the description and the claims in the form itself, because that text is what gets published.
Add applicants and inventors, then tick the declarations –
There is a copy-data option if the inventors are the same as the applicants. The declarations cover possession of the invention, whether a provisional or complete specification accompanies the application, use of biological material sourced from India, absence of any lawful ground of objection, and your status as inventor, assignee or legal representative. Convention, PCT, divisional and patent of addition applications each have their own declaration to tick.
Decide what goes in alongside –
The same screen lets you add Form 9, Form 18 or Form 28 with the application. It also asks whether you want the application filed under the SIPP Scheme 2022, which is subject to approval.
Save it as a draft, and verify your email –
Saved forms sit under Drafted Forms with a temporary application number and the fee amount against them. The grid shows your email verification status, and a resend link if the verification mail has not arrived.
Sign first, then submit and pay –
The portal is explicit on this point: you can submit the form or make payment only after the form has been signed. Payment goes through the government gateway, and anything paid but not yet completed shows up under Pending CBR.
Keep the acknowledgment, and post the originals –
You receive an application number and a Cash Book Receipt number. Proof of right, power of attorney and priority documents still have to reach the office in original.
Patent E Filing Fees Compared with Physical Filing
Applicant category | E-filing fee | Physical filing fee |
Natural person, startup, small entity or educational institution | ₹1,600 | ₹1,750 |
All other applicants | ₹8,000 | ₹8,800 |
The same gap of roughly 10% runs through the smaller charges too, such as the fee for each specification sheet beyond 30 and each claim beyond 10.
A patent of addition under Section 54 attracts a 50% reduction across the board. This concession is often missed.
These figures reflect the First Schedule as at August 2026. Fees are amended from time to time, so confirm the current amount on the official portal before you pay.

New for 2026: Mandatory e-KYC for Portal Access
On 09/07/2026, the Ministry of Commerce and Industry made electronic Know Your Customer verification compulsory for all IP attorneys who practise before the Intellectual Property Office and use the IP India portals. The deadline was later extended to 31/08/2026.
The e-KYC form sits on the e-filing portal itself and opens with existing login credentials. If your agent’s access lapses, your filings stall, so it is worth a quick check.
What Happens After You File
Two dates follow your filing. Only one of them is yours to act on.
Publication happens on its own, 18 months from your filing date or priority date, whichever is earlier, under Section 11A and Rule 24. You may ask for earlier publication on Form 9 if that suits your funding or licensing plans.
The request for examination is your deadline. For applications filed on or after 15/03/2024, Rule 24B requires Form 18 within 31 months of the filing or priority date, whichever is earlier. Applications filed before that date keep the older 48-month period. Section 11B(4) is blunt about the consequence: the application shall be treated as withdrawn by the applicant.
Startups and applications with at least one woman applicant may also seek expedited examination on Form 18A under Rule 24C.
Common Problems During Patent E Filing
Signature errors –
Expired certificates, the wrong certificate class, and browser incompatibility are the usual causes. If your certificate will not authenticate, e-Sign is the built-in fallback.
Payment windows –
Government payment gateways go down for scheduled maintenance. A failed payment means no filing date.
Filing on the deadline day –
The portal has been taken offline for migration before, sometimes at short notice. Leave yourself room.
Wrong fee slab –
Claiming the lower rate without Form 28 attached is a common and avoidable rejection.
Filing Yourself or Instructing a Patent Agent
Nothing stops you from e-filing on your own. Section 6 of the Patents Act allows the true and first inventor, an assignee, or a legal representative to apply, alone or jointly.
What a patent agent adds is not portal access. It is the specification itself, and the judgment behind claim scope, prior art, and how objections are answered a year or two later.
The wider picture explains why this matters. Filings in India reached 1,10,375 in 2024–25, a rise of 19.75% on the previous year, according to the IP India Annual Report 2024–25. Grants in the same year came to 33,504. Getting an application filed is the straightforward part.
