Secure your invention's priority date today — even while it's still in development. A provisional patent application gives you 12 months of "Patent Pending" status, locks in your filing date against competitors, and costs a fraction of a complete patent application.
Under Section 9 of the Patents Act, 1970, an inventor can file a patent application with a provisional specification — a preliminary description of the invention that does not yet need to include formal claims or the full technical detail required for a complete application.
The purpose is simple: when an invention is still being refined, tested, or funded, a provisional application lets you establish your priority date immediately. If two inventors file for the same invention, patent rights go to whoever filed first — the provisional application protects that filing date.
Once filed, you have exactly 12 months (no extension permitted) to file a Complete Specification and convert to a full patent application. The complete application backdates to your original provisional filing date, giving you effective priority from day one.
A provisional application does not get examined by the Patent Office and does not by itself lead to a grant. It is a placeholder — without a complete specification filed within 12 months, the application is deemed abandoned and the priority date is permanently lost.
Your filing date is locked from the day you file. Any subsequent similar invention filed by a competitor is subordinate to yours — regardless of when they file their complete application.
Once filed, you may legally label your product and marketing materials as "Patent Pending" — a powerful commercial signal to competitors and investors.
A provisional application costs just ₹1,600 (individuals/startups) — a fraction of the full complete patent cost. Ideal when invention is still developing or funding is being arranged.
Patent Pending status demonstrates commitment to IP protection. Investors and potential partners are far more willing to engage when an invention is formally filed and protected.
The Indian provisional filing date serves as the priority date for subsequent filings in convention countries and PCT applications, allowing global protection from a single filing date.
Once filed, you can present your invention at conferences, pitch to investors, or publish research without fear of losing patent rights — the priority date protects you.
Understanding when to file provisionally and when to go straight to a complete application is critical. Here's a detailed comparison.
Under Section 6 of the Patents Act, 1970, any of the following persons may apply for a patent — alone or jointly.
Any person who is the original creator of the invention and can claim to be the true and first inventor. This is the most direct route — the inventor files in their own name.
A company, organisation, or individual to whom the inventor has assigned their rights. Common in employer–employee relationships where inventions are made in the course of employment.
Eligible for significantly reduced fees — same as individuals (₹1,600). Must file Form-28 with supporting documents proving startup or MSME status to claim this benefit.
Universities, colleges, and research institutes qualify for the same reduced fee as individuals. Must file Form-28 with evidence of educational institution status.
Any company or large organisation can file a provisional patent application. Government fee is ₹8,000 (up to 30 pages, 10 claims). No Form-28 required.
Foreign inventors and companies can file provisional applications in India to establish an Indian priority date. Must appoint an agent with an address for service in India. Can claim convention priority within 12 months of home country filing.
The provisional specification is filed using Form-2. While it requires less detail than a complete specification, it must still sufficiently describe the invention so a person skilled in the field can understand and reproduce it.
A concise, clear title that accurately describes the invention. Should be specific to the technical field but not so narrow that it limits the scope. Avoid brand names or vague terms.
A brief statement identifying the technical domain — e.g., "The present invention relates to a novel process for water purification using nano-filtration membranes." Sets context for the examiner.
Briefly explain the existing situation, the limitations of current solutions, and the technical problem your invention addresses. Establishes the "inventive step" — why your invention is not obvious.
The core of the provisional specification. Must describe the invention in sufficient detail — components, how they interact, how the invention works, and how it can be made or used. This should not be scarce or vague — inadequate description can weaken your priority date in disputes.
While not strictly mandatory in provisional applications, drawings significantly strengthen the description. A flowchart, schematic, or technical diagram helps establish the scope of your invention and reduces ambiguity during examination of the complete specification.
Summarise the key advantages of the invention over existing solutions. You can also describe different embodiments (variations) of how the invention can be implemented — this broadens the scope of your eventual claims.
The primary application form. Must include full name, nationality, and address of applicant(s) and inventor(s), the title of invention, and declaration of right to file. Signed by applicant or authorised agent.
The provisional specification describing the invention — title, field, background, and description. Does not require claims or abstract. Filed together with Form-1.
If the applicant is not the inventor, a statement of assignment or proof of right from the inventor(s) is required — either endorsed on Form-1 or as a separate assignment deed.
Paid online at ipindiaonline.gov.in via Net Banking, UPI, Debit/Credit Card, or Demand Draft. Amounts: ₹1,600 (Individual/Startup/MSME/Educational Institute) or ₹8,000 (Others). Physical filing adds 10% surcharge.
Required to claim reduced fees. Accompanied by documentary evidence — DPIIT certificate for startups, MSME registration certificate for small entities, or institutional recognition documents. Must be filed with every new application.
A Power of Attorney in Form-26 authorising a registered patent agent to file and prosecute the application on the applicant's behalf. Required when applicant is not filing personally.
Inventions involving biological material from India require prior permission from the National Biodiversity Authority. Must be submitted before the grant of patent — disclose at filing stage.
While optional for provisional applications, technical drawings, flowcharts, or schematics help clearly describe the invention and strengthen the specification against future challenges or disputes.
| Applicant Category | Eligibility | E-Filing Fee | Physical Filing |
|---|---|---|---|
| Natural Person(s) / Individual | Indian citizen filing in personal capacity | ₹1,600 | ₹1,760 |
| Startup | DPIIT-recognised startup — file Form-28 | ₹1,600 | ₹1,760 |
| Small Entity (MSME) | MSME registration certificate — file Form-28 | ₹4,000 | ₹4,400 |
| Educational Institution | Government-recognised institution — file Form-28 | ₹1,600 | ₹1,760 |
| Large Entity / Company | All others not in above categories | ₹8,000 | ₹8,800 |
Above fees are for applications with up to 30 pages of specification and 10 claims. Excess pages attract ₹160/page (individual) or ₹800/page (large entity). Provisional applications don't require claims but any claims added will be counted. Always verify current fees at ipindia.gov.in before filing.
Joint individual + company filing = large entity fee. If an individual and a company jointly file the application, the fee is ₹8,000 — the individual does not retain the reduced rate in joint filings with non-eligible entities.
Before filing, conduct a thorough prior art search using InPASS, Google Patents, and WIPO PatentScope. Confirm that no identical or substantially similar invention has been previously patented or published. This step is not mandatory but is critical — filing without a search risks future rejection or invalidity challenges.
Prepare Form-2 with a clear description of your invention — title, field, background, and detailed description. Include technical drawings if available. The description must be sufficient for a person skilled in the field to understand the invention. Do not undersell it — the provisional must adequately support the claims you intend to make 12 months later.
Fill Form-1 with applicant name, nationality, address, title of invention, and the declaration of right to apply. If claiming startup or MSME status, prepare Form-28 with supporting evidence. If filing through a patent agent, prepare Form-26 (Power of Attorney).
Create an account on the Indian Patent Office's e-filing portal. Upload Form-1, Form-2 (provisional specification), and any additional forms (Form-26, Form-28). Pay the applicable government fee online. Upon successful submission, the system generates a diary number immediately — this is your official acknowledgement and the confirmation of your filing date.
The diary number confirms your filing date — this is your priority date. From this moment, your invention is protected against later-filed applications for the same invention. You may now legally use "Patent Pending" on your product, website, and marketing materials.
Over the next 12 months: refine and finalise your invention, conduct market research, identify potential licensees, apply for funding (using Patent Pending status), file in convention countries if needed, and prepare your complete specification with formal claims. Keep detailed records of development milestones.
File Form-2 with the Complete Specification (full description, claims, abstract, and drawings) within 12 months of the provisional filing date. The complete application backdates to your provisional's priority date. After filing, submit a Request for Examination (RFE) — this is mandatory and must be filed within 31 months (for applications filed on or after 15 March 2024) to avoid deemed abandonment.
Even a well-drafted provisional application cannot lead to a patent if the invention falls under non-patentable subject matter. Always verify before filing.
Mathematical methods, laws of nature, and abstract scientific principles (e.g., a formula or algorithm on its own) are not patentable. Only applications of these are potentially patentable.
Methods of doing business, performing mental acts, or playing games are excluded under Section 3(k) unless tied to a technical implementation that produces a technical effect.
Software code alone is not patentable. However, a computer-implemented invention that produces a technical effect beyond normal software–hardware interaction may qualify.
These are protected by copyright, not patents. Schemes, rules, and methods for performing mental acts are also excluded. Design features may be protected under Design Registration.
Methods of treatment, diagnosis, surgery, or therapy of humans or animals (Section 3(i)) are not patentable in India — though medical devices and drugs themselves can be patented.
Inventions that are essentially traditional knowledge, or aggregations of known properties of traditionally known components, are excluded under Section 3(p). India maintains a Traditional Knowledge Digital Library (TKDL) for prior art searches in this area.
Plants and animals in whole or part are excluded, as are essentially biological processes for production or propagation. Micro-organisms and microbiological processes are patentable (post-TRIPS 2005 amendment).
Any invention relating to atomic energy under Section 4 is entirely excluded from patent protection — no application in this area can proceed regardless of novelty or inventive step.
A provisional patent application takes days, not months. For ₹1,600, you lock in your invention's priority date, get "Patent Pending" status, and protect 12 months of development time. Our experts handle the drafting and filing.
