The Provisional Filing Workflow.

Four sequential stages from invention disclosure to filed provisional application. Typical timeline 1-3 weeks. The deliverable: a filed Form 1 + Form 2 with provisional specification, an IPO acknowledgment, an established priority date, and a 12-month calendar to file the complete specification under Section 9(1).

Stage 1
Disclosure & provisional decision
Invention disclosed under NDA. Provisional vs complete decision: file provisional if the invention is still evolving, if a public disclosure is imminent (product launch, demo day, paper), or if you need 12 months to develop, fundraise, or pivot. Provisional not available for divisional, convention, PCT national phase, or patents of addition.
→
Stage 2
Provisional specification drafting
Provisional specification drafted per Section 10(1) and Rule 13: title, field of invention, background, summary, sufficiently detailed description, drawings if applicable, abstract. No claims required in provisional, but the disclosure must support the eventual claims in the complete specification. Drafted by registered Patent Agent partner.
→
Stage 3
Form 1 + Form 2 filing
Form 1 (Application for Grant of Patent) + Form 2 (Specification, marked provisional) filed on the IPO portal. Government fee per applicant category: ₹1,600 (individual / startup / MSME / educational institution), ₹4,000 (small entity), ₹8,000 (large entity). Form 28 filed if claiming startup status. Power of Attorney filed with Patent Agent.
→
Stage 4
12-month complete specification window
Priority date established. “Patent Pending” status usable. 12-month clock starts under Section 9(1) to file the complete specification with claims (Form 1 + Form 2 complete + Form 5 inventorship). Calendar set with multi-stage alerts: 9 months, 11 months, and final deadline. No extensions exist; missing the window abandons the application.
↺ One-time per invention. The provisional is followed within 12 months by the complete specification (separate engagement). The same invention then proceeds through publication, examination, FER, and grant under Section 43 of the Patents Act, typically 4-6 years total to grant.

What Is a Provisional Patent?

A provisional patent application in India is a filing under Section 9 of the Patents Act 1970 that captures a priority date for an invention before the invention is fully developed and before formal claims are drafted. It is filed using Form 1 (Application for Grant of Patent) and Form 2 (Specification, marked provisional) on the IPO e-filing portal under Rule 13 of the Patents Rules 2003. The provisional gives the applicant 12 months to file the complete specification with claims, during which the invention can be refined, the product can be developed, fundraising can happen, and pivots can occur without losing the original filing position.

Three commercial reasons drive provisional filings. One: an imminent public disclosure, product launch, demo day, conference presentation, or publication, where the disclosure would otherwise bar patentability under the novelty requirement. Filing provisional today preserves novelty before the disclosure happens. Two: the invention is still evolving and the applicant wants priority date protection while engineering and product decisions continue. Three: fundraising or business development requires “Patent Pending” status, useful for investor diligence and competitive positioning, before resources are available to commission a complete specification.

What a provisional is NOT

A provisional is not a granted patent. It confers no enforceable rights. It does not allow you to sue for infringement. It is not examined; the Controller does not assess novelty, inventive step, or industrial applicability at provisional stage. A provisional is purely a priority anchor: it locks in the filing date so that any subsequent prior art arising after the provisional date cannot be cited against your invention. Setting this expectation honestly matters, many applicants assume provisional equals patent, and act on assumptions that the law does not support.

The 12-month deadline is absolute

Under Section 9(1), if the complete specification is not filed within 12 months of the provisional, the application is deemed abandoned and the priority date is permanently lost with no revival mechanism. The IPO does not grant extensions on this deadline. Any new matter (new features, new embodiments) added in the complete specification within the 12-month window only gets priority from the provisional date if it was disclosed in the provisional; new matter added later gets the complete-filing date as its priority. Provisional drafting therefore needs to be sufficiently broad: capture the future as well as the present.

When provisional is not available

Provisional filings are only available for ordinary applications where India is the first-filing country. Provisional cannot be used for Convention applications (claiming Paris Convention priority from a foreign filing), PCT national phase applications (international applications entering India), Divisional applications, or Patents of Addition. In all those cases, the complete specification must be filed at the outset. If you have already filed in another country, you cannot now file a provisional in India to capture an earlier date.

What Gets Done Each Cycle.

Six activities across the provisional filing workflow. From the decision to file provisional through the calendar that takes you to complete specification within 12 months.

Provisional vs complete decision
Pre-filing
Strategy session on whether to file provisional or go straight to complete. Provisional fits an evolving invention or imminent public disclosure. Complete fits a finished invention with formal claims ready. Wrong choice wastes fees or surrenders priority date scope.
Invention disclosure under NDA
Pre-filing
NDA signed before any technical disclosure. Invention disclosed in detail: technical problem, solution, embodiments, drawings, working prototypes. Anything not disclosed in the provisional gets no priority date if added later in the complete specification.
Provisional specification drafting
Filing
Provisional specification drafted per Section 10(1): title, field, background, summary, detailed description, drawings, abstract. No claims required, but disclosure must be broad enough to support the eventual complete claims. Drafted by registered Patent Agent partner.
Form 1 + Form 2 filing
Filing
Form 1 (application) + Form 2 (provisional specification) + Form 28 (if startup / MSME claim) filed on the IPO e-filing portal. Government fee paid per category. Acknowledgment with application number issued same day. Priority date established.
12-month conversion calendar
Post-grant
Calendar set with alerts at 6 months, 9 months, 11 months, and final deadline (Day 365). No extension exists; Section 9(1) makes the deadline absolute. Conversion planning begins at 6 months; complete specification drafting begins by 9 months at latest.
Foreign filing strategy
Pre-filing
If foreign filing is anticipated (US, EP, PCT), the Indian provisional priority date triggers the Paris Convention 12-month window to file in convention countries. PCT international application can be filed at or before 12 months claiming Indian priority. Foreign strategy mapped at provisional stage, not delayed to complete.

When You Need Us to Handle This.

A provisional filing looks simple but the strategic and drafting choices made today determine whether the eventual complete specification holds up. Here's when professional handling pays back.

Get help if
  • You have an imminent public disclosure deadline. Product launch, demo day, paper, pitch, anything that puts the invention in the public domain triggers a novelty bar. The provisional must be filed before the disclosure, not after. Tight timelines need professional handling to avoid scrambling under deadline pressure.
  • The invention is still evolving and you want to capture priority now. Provisional drafting needs to be broad enough to cover the invention's likely future direction. Too narrow and the complete specification's additions lose priority. Too broad and the disclosure may not actually support what you build. Drafting this trade-off well is a Patent Agent's job.
  • You're planning foreign filings (US, EP, PCT). The Indian provisional priority date triggers the Paris Convention 12-month window for foreign filings. Foreign strategy must be planned at provisional stage; waiting until complete specification is too late. Multi-jurisdiction planning is technical and high-stakes.
  • You're raising capital and need “Patent Pending” status for diligence. Investors check patent filings during diligence. A properly filed provisional from a registered Patent Agent carries credibility; a DIY provisional that fails on disclosure adequacy does not. The cost of a professional provisional is trivial against the cost of a delayed or discounted round.
  • Your invention is software, fintech, or has Section 3 risk. Section 3(k) (software per se, business methods) and other Section 3 exclusions need to be navigated at provisional drafting stage, not discovered at examination. A registered Patent Agent drafts around Section 3 risks; DIY filings often disclose in ways that trigger exclusion.
Consider DIY if
  • You have an in-house Patent Agent or established IP team. Established R&D-heavy companies with in-house Patent Agents file provisionals routinely. External support is engaged for jurisdiction-specific filings or specialised technical domains.
  • You are an individual inventor filing for personal exploration. Solo inventors with technical writing ability and a well-defined invention can file Form 1 + Form 2 directly on the IPO portal. Government fee is ₹1,600 (individual category). Quality of drafting determines what survives to complete specification.
  • You're defensively filing a low-commercial-value invention. Defensive filings where you do not plan to enforce or license can proceed with lighter drafting. The risk-adjusted cost of professional drafting may exceed the value of the patent.
  • The invention is finished and ready for complete specification. If your invention is fully developed with claims that can be drafted today, skip provisional and file complete directly. Provisional only adds value when you genuinely need the 12-month window or face a disclosure deadline.

How We Work.

Six commitments. A CA-led IP team in partnership with registered Patent Agents (Section 126 of the Patents Act 1970), drafting your provisional specification with care, filing under deadline pressure, and managing the 12-month conversion calendar all the way to complete specification.

NDA signed before invention disclosure
Non-disclosure agreement signed before you share any technical detail. India's patent law treats prior public disclosure as a novelty bar; we treat your invention as confidential from first contact. NDA covers our team and the registered Patent Agent partner drafting the provisional specification.
Provisional drafted & filed in 1-3 weeks
From invention disclosure to filed Form 1 + Form 2 with acknowledgment number: 1-3 weeks standard. Expedited filing (3-5 working days) available where a public disclosure deadline forces it. We do not file in a rush that compromises the disclosure adequacy.
Broad disclosure that supports future claims
Provisional specification drafted broadly enough that the complete specification's claims (filed up to 12 months later) get full priority back to the provisional date. Too narrow and additions lose priority; too broad and disclosure fails to support claims. We draft for both.
Section 3 risk navigated at drafting
Software, business methods, mathematical methods, abstract ideas, all navigated at provisional drafting stage. Disclosure is framed to emphasise technical effect and hardware integration where applicable. Many DIY provisionals disclose in ways that later trigger Section 3 rejection; ours do not.
Registered Patent Agent files the application
Form 1 + Form 2 + Form 28 (if applicable) filed by a registered Patent Agent (Section 126 of the Patents Act 1970) under their registration. Power of Attorney from you to Patent Agent. Filing acknowledgment delivered with application number and priority date confirmed.
12-month conversion calendar with multi-stage alerts
Section 9(1) clock starts on filing day. Calendar set with automated alerts at 6 months, 9 months, 11 months, and final deadline. Conversion to complete specification begins at 6 months; no provisional in our care lapses for missing the 12-month deadline.

What a Provisional Catches and What It Doesn’t.

Provisional filings are commonly misunderstood. The page sets honest expectations: what a provisional captures (priority, optionality, signalling) and what it absolutely does not (enforceable rights, granted protection, extensions). Both columns matter.

Risk if unregistered
Likelihood
Commercial impact
Catches: priority date
Always
Filing date becomes the reference for novelty assessment; later prior art cannot be cited
Catches: “Patent Pending” status
From filing date
Useful for investor diligence, competitive positioning, and marketing without overclaiming
Catches: 12-month optionality
Time to develop
Refine invention, complete prototype, raise capital, decide on full claims, before complete specification
Catches: Paris Convention 12-month window
Foreign strategy
Indian provisional triggers 12-month window to file convention applications in 170+ Paris Convention countries
Doesn’t catch: enforceable patent rights
No grant
Provisional is not a granted patent; cannot sue for infringement, cannot license as a granted patent
Doesn’t catch: claim-level protection
No claims yet
Provisional has no formal claims; final patent scope is set by complete specification claims, filed within 12 months
Doesn’t catch: priority for new matter
Late additions
New features added in complete specification but not disclosed in provisional get the complete-filing date, not provisional
Doesn’t catch: deadline relief
Absolute
12-month deadline under Section 9(1) has no extension, no revival; abandonment is permanent and the priority date is lost
Provisional is a powerful priority anchor with real but limited reach. Used well, it preserves novelty, enables foreign filing, and buys a year. Mistaken for a granted patent, it leads to commercial overreach and downstream surprise when claims are challenged. The honest framing is the strategic framing.

Frequently Asked Questions.

A provisional patent application is a filing under Section 9 of the Patents Act 1970 that captures a priority date for an invention before the invention is fully developed and before formal claims are drafted. It is filed using Form 1 (Application for Grant of Patent) and Form 2 (Specification, marked provisional) on the IPO e-filing portal. The provisional gives the applicant 12 months to file the complete specification with claims, during which the priority date is preserved against later prior art.
No. A provisional is not a granted patent. It confers no enforceable rights, you cannot sue for infringement based on a provisional. It is not examined; the Controller does not assess novelty, inventive step, or industrial applicability at provisional stage. A provisional is purely a priority anchor: it locks in the filing date so that prior art arising after the provisional date cannot defeat your invention. “Patent Pending” status is permissible from filing date, but commercial overclaiming based on a provisional is risky.
Government fees per applicant category: ₹1,600 for individual / startup / MSME / educational institution; ₹4,000 for small entity; ₹8,000 for large entity / company. Startup and MSME status must be claimed by filing Form 28 with appropriate certifications. Professional fees for drafting the provisional specification and filing through a registered Patent Agent are additional. Total cost is significantly lower than complete specification filing. Reach out for an exact quote.
Provisional: filed when the invention is still evolving; uses Form 1 + Form 2 (provisional specification); no claims required; secures a priority date for 12 months; lower government fee; cheaper to draft. Complete: filed when the invention is finished; uses Form 1 + Form 2 (complete specification) + Form 5 (inventorship); formal claims required defining the scope of protection; goes to publication and examination; higher government fee; more rigorous drafting. Provisional must be followed by complete within 12 months; you cannot have a provisional alone for the entire life of the invention.
Under Section 9(1) of the Patents Act 1970, the application is deemed abandoned. The priority date is permanently lost with no revival mechanism. The IPO does not grant extensions on this deadline. You can refile as a new application, but the original priority date is gone, any prior art that arose between the provisional and the refile date may now be citable against you. The 12-month deadline is the single most important date in provisional practice; set hard reminders well before the deadline.
No. Provisional applications are only available for ordinary applications where India is the first-filing country. If you have already filed in another country (US, EP, anywhere), you cannot file an Indian provisional and capture an earlier date. Your options are: file a Convention application in India within 12 months of the foreign filing (claiming Paris Convention priority) or file a PCT national phase entry within 31 months of the priority date. Both require complete specification at filing, not provisional.
Under Section 126 of the Patents Act 1970, only registered Patent Agents can file patent applications on behalf of clients. Individual inventors can file on their own behalf without a Patent Agent. Companies and other applicants typically file through registered Patent Agents because the drafting quality directly affects the eventual claims and patentability. We partner with registered Patent Agents who handle the filing under their registration.
File provisional if: (1) the invention is still evolving and you need 12 months to refine it; (2) a public disclosure (product launch, demo, paper, pitch) is imminent and you need to preserve novelty before disclosure; (3) you want priority for fundraising / diligence purposes while finalising claims; (4) you anticipate foreign filings and want to trigger the Paris Convention 12-month window. File complete directly if: the invention is finished, claims are ready, and you have no need for the 12-month buffer. We advise on the choice at engagement start.
Under Section 10(1) of the Patents Act 1970 and Rule 13 of the Patents Rules 2003, the provisional specification needs: title of the invention; field of invention; background and existing problem; summary of the invention; detailed description of the invention sufficient to enable a person skilled in the art to understand it; drawings if applicable; abstract. Claims are not required in the provisional. The disclosure must be broad enough to support the eventual claims in the complete specification, anything not disclosed in the provisional loses provisional priority for the complete.
Yes, but with a catch on priority. New features not disclosed in the provisional can be added in the complete specification, but they will only get the complete-filing date as their priority, not the provisional date. The provisional priority date attaches only to the matter disclosed in the provisional. This means: if a competitor files between your provisional and your complete with subject matter that overlaps your “new additions”, they may have priority on those additions. Provisional drafting therefore needs to be sufficiently broad to anticipate likely future claim scope.
Yes, this is one of the most strategic uses of an Indian provisional. Filing in India triggers the Paris Convention 12-month priority window: you can file in 170+ Paris Convention countries within 12 months and claim the Indian provisional filing date as your foreign priority date. Alternatively, file a PCT international application within 12 months of the Indian provisional; the PCT then gives you 30-31 months from priority date to enter national phase in PCT contracting states. Foreign filing strategy should be planned at provisional stage.
Pricing depends on: (1) technical complexity of the invention, mechanical, electrical, chemical, software, biotech all draft differently; (2) urgency, standard 1-3 weeks vs expedited filing for imminent disclosure deadlines; (3) foreign filing strategy, whether the provisional is being filed as part of a multi-jurisdiction strategy; (4) complexity of disclosure, number of embodiments, drawings, and supporting material. Government fee starts from ₹1,600 (individual / startup / MSME). Professional fees quoted as a fixed engagement once scope is clear.
