Patent Registration in India

Patent registration in India means filing an application with the Indian Patent Office in Form 1 with a provisional or complete specification in Form 2, then requesting examination in Form 18 within 31 months of the priority or filing date. The official filing fee is ₹1,600 for an individual, startup or small entity and ₹8,000 for others, and a granted patent lasts 20 years from filing. CorporateWalla coordinates the search, drafting brief, filing and objection replies, and the filing and prosecution are handled with our registered patent agent partner.

Who Should File a Patent, and Which Fee Category Applies

Any inventor, or the assignee of an inventor, can apply for a patent in India for a product or process that is new, involves an inventive step and is industrially applicable. The application can be filed by an individual, a company, an LLP, a university or a government body. The fee you pay depends on the applicant category, so it is worth fixing the right applicant before filing.

ApplicantFee columnHow it is claimedExpedited examination (Form 18A)
Individual inventor (natural person)ReducedApplicant details in Form 1Only if a female applicant is among natural-person applicants
DPIIT-recognised startupReducedForm 28 with proof of recognitionEligible
Small entity (MSME)ReducedForm 28 with proof of statusEligible
Educational institutionReducedApplicant details and supporting proofOnly through another Rule 24C ground
Other companies and LLPsStandard (about five times higher)Not applicableOnly through another Rule 24C ground

If an application is later transferred to an applicant outside the reduced-fee categories, the new applicant pays the fee difference with the transfer request (Rule 7(3), Patents Rules, 2003).

Provisional vs Complete Specification

PointProvisionalComplete
PurposeSecures the priority date earlyDefines what is protected and is examined
ClaimsNot requiredRequired
When to useInvention still being refined, or you need to disclose it soonInvention is final and tested
Next deadlineComplete specification within 12 monthsForm 18 within 31 months of priority
RiskMatter added later may not get the earlier priority dateHigher drafting cost upfront

A provisional filing is not a cheaper patent. It buys up to 12 months, and the complete specification still has to be drafted properly. Everything you want protected should be described in the provisional, because only what it discloses carries the earlier priority date.

Common Mistakes That Lose Patent Rights

  • Publishing, selling or pitching the invention publicly before filing, which can destroy novelty
  • Filing a thin provisional and adding the real invention only in the complete specification
  • Missing the 12-month complete specification deadline after a provisional
  • Forgetting Form 18, so the application is treated as withdrawn after 31 months
  • Not filing Form 3 within six months or not updating it after the first statement of objections
  • Filing in a founder's personal name without an assignment to the company that will use the patent
  • Claiming startup or small-entity fees without Form 28 and proof
  • Drafting claims around software per se or a business method instead of the technical effect
  • Letting renewal fees lapse after grant

Worked Example: A Hardware Startup Files a Patent

A DPIIT-recognised Bengaluru startup has a working prototype of a low-power water-quality sensor and a product demo planned for investors in six weeks.

  • Week 1–2: invention disclosure and drafting brief; our patent agent partner prepares a provisional specification; Form 1, 2, 3, 26 and 28 are filed online. Official fee: ₹1,600.
  • Week 6: the demo goes ahead after the priority date is secured.
  • By month 12: the complete specification with 14 claims and 34 sheets is filed with Form 5 and Form 18A. Extra claims cost 4 × ₹320 = ₹1,280, extra sheets 4 × ₹160 = ₹640, and Form 18A ₹8,000.
  • After the first statement of objections: the reply and claim amendments are filed within six months.

Official fees to this point come to about ₹11,520 at the reduced rates. A company outside the reduced categories filing the same application would pay ₹8,000 + ₹6,400 (claims) + ₹3,200 (sheets) + ₹20,000 for normal examination in Form 18, or about ₹37,600; it can use Form 18A (₹60,000) only if it meets another Rule 24C ground.

Illustrative scenario. Actual fees depend on the specification length, claims and applicant category at the time of filing.

Current Position as of October 2026

  • The request for examination is due within 31 months of the priority or filing date (Rule 24B, as amended by the Patents (Amendment) Rules, 2024; earlier 48 months).
  • Form 3 is due within six months of filing, and foreign-filing updates within three months of the first statement of objections (Rule 12).
  • The statement of working in Form 27 is filed once for every block of three financial years after grant, within six months of the block ending (Rule 131).
  • Expedited examination under Rule 24C is open to startups, small entities, female applicants, government bodies and certain international applications.

Government fee — paid by you at actuals

Official e-filing fees (First Schedule, Patents Rules, 2003), natural person / startup / small entity / educational institution vs others: Form 1 application ₹1,600 / ₹8,000; each sheet over 30 ₹160 / ₹800; each claim over 10 ₹320 / ₹1,600; Form 9 early publication ₹2,500 / ₹12,500; Form 18 examination ₹4,000 / ₹20,000; Form 18A expedited examination ₹8,000 / ₹60,000; Form 28 (startup / small entity status) no fee. Paid separately at actuals.

Every price above is a professional fee, excluding GST and government charges. 50% upfront, 50% on delivery.

The starting price covers one invention filed as a provisional application or a straightforward complete application by an individual, startup or small entity. Complete specifications for complex inventions, PCT national phase, FER replies and hearings are quoted after the patent agent reviews the invention disclosure.

How it works

Step 1

Invention review and search

You share an invention disclosure; we check what is new and, if ordered, run a patentability search against Indian and international databases.

Step 2

Choose provisional or complete

File provisional to lock the priority date while the invention is still developing, or go straight to a complete specification if it is ready.

Step 3

Drafting with the patent agent

Our registered patent agent partner drafts the specification and claims from the brief we prepare with you; you approve the final draft.

Step 4

Online filing

Form 1 with Form 2 and the supporting forms are filed on the Patent Office e-filing system and the application number and priority date are issued.

Step 5

Publication and examination

The application is published after 18 months (earlier on Form 9) and examined after the Form 18 request, filed within 31 months.

Step 6

Objections, hearing and grant

The application must be put in order within six months of the first statement of objections; replies and any hearing lead to grant or refusal.

Why CorporateWalla®?

Priority date first

A provisional filing fixes your priority date quickly, so you can pitch, test or seek funding while the complete specification is prepared within 12 months.

Registered patent agent drafting

Specifications and claims are drafted and filed by our registered patent agent partner; CorporateWalla runs the brief, timelines and paperwork.

Lower fees where you qualify

We check startup, small-entity or natural-person status and file Form 28 so the reduced official fee schedule applies.

Deadline tracking

The 12-month, 31-month, six-month and renewal deadlines are diarised, because missing most of them abandons the application.

One IP desk

Patent, trademark and copyright protection for the same product handled together, so names, code and inventions each get the right form of protection.

Official fees for an individual, startup or small entity are ₹1,600 for the application and ₹4,000 for the examination request, or ₹8,000 and ₹20,000 for other applicants.
