A provisional patent application is a preliminary filing under Section 9 of the Patents Act, 1970 that secures an early priority date for an invention before it is fully developed — often the first step before full patent registration. With 23+ years of exclusive IP practice and 5000+ trademarks filed, we help inventors file it for as little as ₹1,600 in government fees, giving 12 months to file the complete specification before the application is treated as abandoned.
What Is a Provisional Patent Application?
A provisional patent application is filed using Form 1 (application for grant of patent) and Form 2 (provisional specification), governed by Section 9 and Section 10(1)/(2) of the Patents Act, 1970, and Rule 13 of the Patents Rules, 2003. Unlike a complete specification, formal claims are optional at this stage — the goal is simply to establish, on record, that you were in possession of the invention on that date.

Why Should You File a Provisional Application First?
- Early priority dateLocks in your filing date while you continue developing the invention
- Lower upfront costProvisional filing is cheaper than a complete specification with full claims and drawings
- 'Patent Pending' statusLets you disclose the invention to investors or use it commercially with reduced risk
- Time to refine12 months to finalise claims, run prior-art searches, and gather R&D data before committing to the complete specification
What Forms and Fees Are Required?
| Requirement | Detail |
|---|---|
| Forms required | Form 1 (application for grant of patent) + Form 2 (provisional specification) |
| Government fee — individual/natural person | ₹1,600 (e-filing) |
| Government fee — startup/small entity | Reduced fee slab applies |
| Government fee — large entity | Higher fee slab applies |
| Professional/attorney fees | Typically ₹15,000–₹25,000 depending on complexity (separate from government fee) |
| Complete specification deadline | 12 months from the provisional filing date — Section 9(1) |
How to File a Provisional Patent Application — Step by Step
- Draft the provisional specificationDescribe the invention in enough technical detail to establish possession of the idea — claims are optional at this stage
- File Form 1 and Form 2Submit through the IP India e-filing portal or in physical form at the appropriate Patent Office
- Pay the government fee₹1,600 for individual applicants, subject to entity-based fee slabs
- Receive acknowledgementThe Patent Office issues a filing date and application number, which becomes your priority date
- Develop and refineUse the 12-month window to finalise claims, drawings, and prior-art search before filing the complete specification
What Happens If You Miss the 12-Month Deadline?
If the complete specification isn't filed within 12 months, the application is deemed abandoned under Section 9(1) of the Patents Act, 1970 — there's no extension and no revival. You lose the priority date permanently and would need to file a fresh application, risking that someone else discloses or files a similar invention in the meantime.

|---|---|---|
| Purpose | Secures priority date | Defines full scope of patent protection |
| Claims | Optional | Mandatory |

Frequently Asked Questions
Is filing a provisional patent application mandatory?
No, it's optional — an inventor can go straight to a complete specification if the invention is fully developed and ready.
Can I convert a provisional application back after filing?
The reverse is possible in limited circumstances, but a provisional cannot be extended beyond 12 months — the complete specification must be filed within that window.
What happens if my invention changes during the 12 months?
Any new matter beyond what was disclosed in the provisional specification won't get the benefit of the earlier priority date, so significant changes may need a fresh provisional filing.
Do I get 'Patent Pending' status after filing a provisional application?
Yes, once the application is filed and acknowledged, you can mark your invention 'Patent Pending.'
Can a provisional application be filed for a divisional or PCT application?
No — provisional specifications cannot be filed for divisional, convention, or PCT national phase applications; these require a complete specification.
How much does professional drafting cost in addition to government fees?
Attorney/professional drafting typically costs ₹15,000–₹25,000, on top of the ₹1,600 government fee for individual applicants, depending on the invention's technical complexity.
