Patent Registration in India: Costs, Timeline & How to Apply
Most people who come to us already know they want a patent. What they don’t know is how much it’ll actually cost, how long it’ll realistically take, and which deadlines can destroy the entire application if missed.
This page covers exactly that. It’s not a step-by-step filing walkthrough (we’ve written a separate process guide for that). This is the information you need before you commit: the money, the timeline, the paperwork, and the traps.
Who Can File a Patent in India?
Pretty much anyone with a real invention. The Indian Patents Act, 1970 allows the following to file, either individually or jointly:
- Individual inventors (Indian or foreign)
- Startups recognised by DPIIT
- Small entities registered as MSMEs under the Udyam portal
- Companies of any kind: private, public, LLP
- Universities and educational institutions
- Government departments and government-funded institutions
- Legal representatives of a deceased inventor
When the applicant isn’t the inventor (a company filing for an employee’s invention, for example), you’ll need an assignment deed or proof of right to file.
Your category affects your fees directly. The IPO splits all applicants into two brackets: the lower bracket covers natural persons, startups, small entities, and educational institutions. Everyone else, meaning large companies, pays the higher rate.
What Patent Registration Costs in India (2026)
Two things make up the cost: government fees paid to the IPO, and professional fees paid to your patent agent or attorney.
Government Fees (E-filing)
The IPO has two fee categories. Natural persons, DPIIT-recognised startups, small entities (MSMEs), and educational institutions all fall in the lower bracket. Large companies pay the higher rate. All figures below are e-filing fees. Physical filing costs about 10% more.
| Fee Type | Natural Person / Startup / Small Entity / Educational Institution | Others (Large Entity) |
|---|---|---|
| Application Filing (up to 30 pages, 10 claims) | ₹1,600 | ₹8,000 |
| Early Publication Request | ₹2,500 | ₹12,500 |
| Request for Examination (Normal) | ₹4,000 | ₹20,000 |
| Request for Examination (Expedited) | ₹8,000 | ₹60,000 |
| Extra Pages (per page beyond 30) | ₹160 | ₹800 |
| Extra Claims (per claim beyond 10) | ₹320 | ₹1,600 |
| Hearing Fee | ₹1,500 | ₹7,500 |
| Amendment Before Grant | ₹800 | ₹4,000 |
| Extension of Time (per month, under Rule 24B) | ₹1,000 | ₹4,000 |
Here’s what a standard filing looks like for a startup or individual inventor (under 30 pages, 10 claims or fewer, normal examination):
Compare that to a large company: ₹8,000 + ₹20,000 = ₹28,000 for the same filing. That’s 5× more. The gap is even steeper with expedited examination: ₹8,000 versus ₹60,000.
Renewal Fees (Annual, from Year 3)
Your patent stays valid for 20 years from the filing date, but only if you keep paying annual renewal fees starting from the 3rd year. Miss a renewal and the patent lapses.
| Year | Natural Person / Startup / Small Entity / Educational Institution | Others (Large Entity) |
|---|---|---|
| 3rd to 6th year | ₹800/year | ₹4,000/year |
| 7th to 10th year | ₹2,400/year | ₹12,000/year |
| 11th to 15th year | ₹4,800/year | ₹24,000/year |
| 16th to 20th year | ₹8,000/year | ₹40,000/year |
Professional Fees: What Lexgin Charges
Government fees are only half the picture. You also need a patent agent to search prior art, draft the specification, file the application, and handle prosecution later (FER responses, hearings, amendments).
Most IP firms in India charge ₹15,000 to ₹40,000 just for drafting and filing. At Lexgin, the pricing looks very different:
| Service | Lexgin Fee |
|---|---|
| Patent Searching, Drafting & Filing | ₹5,000 |
| Request for Examination Filing | ₹800 |
| FER Response | ₹5,000 |
| Hearing / On Grant | ₹5,000 |
| NBA Application Preparation | ₹2,000 |
GST @18% applicable on all professional fees.
That’s 40 to 70% lower than what most IP firms charge. And this isn’t a bare-bones service. Lexgin handles 1,500+ IPR filings a year across 50+ universities and 15,000+ researchers. The volume is how we keep pricing this low without cutting quality.
For a startup or individual inventor going through normal examination, the all-in cost (government fees + Lexgin professional fees) for the full cycle from filing to grant typically lands between ₹20,000 and ₹30,000. That covers search, drafting, filing, examination, FER response, and hearing. The exact number depends on complexity, number of claims, and whether you need early publication or expedited examination.
How Long Does It Actually Take?
The short answer:
Most of that 3 to 5 year timeline is queue time. Your application sits at the IPO waiting for an examiner after you file the Request for Examination. The actual work on your end (prior art search, drafting, filing, responding to the FER) takes months, not years.
Something that catches a lot of applicants off guard: provisional protection starts from the day you file. Your application number and filing date establish priority even before the patent is examined or granted. That’s why filing early matters more than filing perfectly.
Who Qualifies for Expedited Examination?
Not everyone. Under Rule 24C, the eligible categories are:
- DPIIT-recognised startups
- Small entities (MSMEs registered under Udyam)
- Female applicants, but only where all applicants are natural persons and at least one is female. A voter ID or government-issued photo ID is needed as proof.
- Government departments and government-financed institutions
- PCT applicants who chose India as ISA or IPEA
This is a common misunderstanding. Universities and educational institutions are not eligible for expedited examination under Rule 24C. This is true even if a female inventor is named as applicant, because the applicant is the institution, not a natural person. If faster processing matters, universities should explore filing through a startup entity or small entity route where applicable.
Key Timeline Milestones
- Day 1Filing date established. Provisional protection begins.
- 1 to 2 weeksApplication number and filing receipt issued by IPO.
- ~1 monthEarly publication (if requested). Otherwise, publication happens automatically 18 months from filing.
- 31 monthsDeadline to file Request for Examination (RFE).
- 6 to 12 monthsFirst Examination Report (FER) issued after RFE is filed.
- 6 monthsDeadline to respond to FER from the date of the report.
- VariableHearing (if needed), then grant order, then patent published in Journal.
At Lexgin, we turn around the parts we control 60% faster than the industry average. That means 8 to 12 months for search, drafting, filing, and FER response, compared to 18 to 24 months at most firms. The IPO’s examination queue is the one piece nobody can speed up, short of qualifying for expedited examination.
Documents You’ll Need to File
Getting the paperwork right from day one saves you months of delays. Here’s the full list.
Core Filing Documents
- Form 1: Application for Grant of Patent (applicant details, title, priority claims)
- Form 2: Provisional or Complete Specification (the patent document itself: description, claims, abstract, drawings)
- Form 3: Statement and Undertaking regarding foreign applications (filed even if you haven’t applied abroad)
- Form 5: Declaration of Inventorship
- Power of Attorney (POA): Authorising your patent agent to act on your behalf
Supporting Documents (where applicable)
- Proof of right / assignment deed: When the applicant is different from the inventor
- Priority document: If claiming convention priority from an earlier foreign filing
- DPIIT recognition certificate: To claim startup fee concession
- MSME/Udyam registration: To claim small entity classification
- Voter ID or government photo ID: For female applicants seeking expedited examination
- Sequence listing in WIPO ST.26 XML format: Required for biotech/pharma inventions involving nucleotide or amino acid sequences
This catches more applicants than you’d expect. Without a signed POA on file, your patent application will not be published by the IPO. And if the POA is delayed beyond 3 months from the filing date, a penalty of ₹10,000 per month kicks in. Think about that: the government filing fee for a startup is ₹1,600. A few months of POA delay can cost you more than the entire application. Get it signed on the day of filing itself, if possible.
Form 3 (the foreign filing statement) has to be submitted within 3 months of filing your Indian application. Even if you haven’t filed abroad and have no plans to, you still need to file Form 3 declaring exactly that. Missing this deadline creates a compliance issue that can hold up your entire application.
Online vs Offline Filing
You can file through the IP India e-filing portal or physically at one of the four Patent Office branches in Delhi, Mumbai, Chennai, or Kolkata.
Honestly, there’s no reason to file physically anymore. E-filing is better on every count:
- Cheaper: E-filing fees are about 10% lower than physical filing across the board.
- Exclusive access to expedited examination: Form 18A can only be filed electronically. Physical filing isn’t an option for it.
- Instant acknowledgment: You get your filing receipt and application number right away.
- No travel required: File from anywhere in India (or abroad, for that matter).
- Better tracking: Check status, download documents, and respond to office actions online.
Lexgin files everything electronically. All fees in this article are e-filing rates.
Deadlines That Can Kill Your Application
Patent law doesn’t give second chances on most deadlines. Here are the ones you need to track carefully.
- 3 months
Power of Attorney: File within 3 months of the application date. Without it, the application won’t be published. After 3 months, a ₹10,000/month penalty applies. - 3 months
Form 3: Statement on foreign filings. Due within 3 months of your Indian filing date, even if you haven’t filed abroad. - 12 months
Provisional to Complete Specification: If you filed a provisional, the complete specification must follow within 12 months. Miss this and the application is abandoned permanently. No extension. No restoration. No remedy. - 31 months
Request for Examination (RFE): Must be filed within 31 months of the filing date. Without it, the IPO simply won’t examine your application. - 6 months
FER Response: You get 6 months from the FER date to respond. An extension of 3 months is available by filing Form 4 with fee. - 15 days
Hearing Response: Written submissions are due within 15 days of the hearing notice. - ~3 days before
Hearing Attendance Confirmation: Confirm that you or your attorney will attend the hearing. Do this at least 3 days before the scheduled date.
We see this go wrong more often than it should. If you file a provisional specification and don’t follow up with the complete specification within 12 months, the application is treated as abandoned. There is no way to fix this. No extension mechanism exists. No late fee can save it. No appeal is available. And here’s the worst part: any research you published or disclosed during those 12 months now becomes prior art that works against you if you file a fresh application. This is the single most expensive mistake an inventor can make.
Why Professional Help Changes the Outcome
Can you file a patent without a patent agent? Legally, yes. Individual inventors are allowed to file on their own. But in our experience, self-drafted applications run into more FER objections, go through more rounds of back-and-forth with the examiner, and take significantly longer to reach grant. Many don’t reach grant at all.
The claims section is where most self-filed applications fall apart. A claim that’s too broad gets rejected outright. A claim that’s too narrow gives you a granted patent that doesn’t actually protect your invention from competitors. Getting that balance right takes experience.
Here’s what working with an experienced firm actually changes:
- Fewer FER rounds. A strong specification with well-drafted claims means fewer objections from the examiner and faster resolution.
- Correct classification from day one. Filing under the right applicant category with the right supporting documents avoids fee disputes and delays.
- Deadline management. With seven different deadlines to track (some as short as 15 days), having a firm manage your docket means nothing falls through the cracks.
- FER strategy. Responding to an FER isn’t just about answering objections. It’s about knowing which claims to amend, which to argue, and which to concede.
- Hearing representation. If it goes to a hearing, your patent attorney argues the case before the Controller. That’s not something you want to attempt yourself unless you’ve done it before.
