Secure your date today: A provisional application can be filed quickly — often within 24–48 hours — immediately establishing your priority date. From that date, you are protected against anyone who files for the same invention later.
What is a Provisional Patent Application?
A provisional patent application is a preliminary filing under the Patents Act, 1970 that secures a priority date for your invention without requiring a complete patent specification with formal claims. It is designed for inventors who have conceived an invention but need time to fully develop it, prepare complete technical documentation, or assess its commercial potential before committing to the full cost of a complete patent application.
The provisional application must describe the invention in sufficient detail for the concept to be understood. It does not need to include formal patent claims. Within 12 months of the provisional filing date, the applicant must file a complete specification with full claims — or the provisional application lapses and the priority date is lost.
Key Benefits of Provisional Filing
- Immediately establishes your priority date — you are protected against anyone who files later
- Gives 12 months to fully develop the invention and prepare complete claims
- Permits public disclosure, fundraising, investor presentations and pilot production after filing
- Allows use of the term "Patent Pending" — signals pending protection to competitors
- Faster and less expensive than filing a complete application at the outset
- Preserves patentability while you assess commercial viability of the invention
- Can form the basis of a PCT international application within 12 months
- Gives time to identify the best jurisdiction strategy before committing to national filings
Provisional vs Complete Application
No formal claims required. Brief description of the invention. Filed quickly to secure priority date. Lapses if complete specification not filed within 12 months. Does not grant patent rights.
Full specification with formal claims required. Detailed description, drawings and abstract. Proceeds to examination. Forms the basis for grant of patent rights after successful prosecution.
Provisional Application Filing Process
Invention Disclosure
You describe your invention to us under strict confidentiality — concept and key features
Prior Art Check
Quick prior art search to assess basic novelty before filing the provisional
Provisional Drafted
Provisional specification drafted describing the invention in sufficient detail
Filed Within 24–48 hrs
Application filed before the Indian Patent Office — priority date secured immediately
12-Month Window
You develop invention, assess commercial potential, prepare complete specification
Complete Spec Filed
Complete specification with claims filed within 12 months — patent prosecution begins
Do not disclose before filing: Never publicly disclose your invention before filing even a provisional application. Any public disclosure before the filing date destroys novelty and makes the invention unpatentable — even with a provisional application in hand. File first, disclose after.

Frequently Asked Questions
What is a provisional patent application?
A provisional patent application is a preliminary filing under the Patents Act, 1970 that establishes a priority date for an invention without requiring complete patent claims or a formal specification. It is the fastest way to secure legal recognition of the date of your invention, giving you 12 months to develop the invention fully and file a complete specification before the provisional application lapses.
What are the benefits of filing a provisional patent application?
The primary benefit is immediate establishment of a priority date — from which your claim to the invention is measured against all later filers. After filing, you may publicly disclose the invention, present it to investors, and begin commercialisation without losing patentability. The 12-month window gives you time to assess commercial viability, identify licensing partners, and prepare a comprehensive complete specification with professional patent claims. The term "Patent Pending" can also be used from the provisional filing date.
What happens if I do not file a complete specification within 12 months?
If the complete specification is not filed within 12 months of the provisional application date, the provisional application is automatically treated as abandoned and the priority date is permanently lost. If any public disclosure occurred during the 12-month window — presentations, publications, product launch — the invention may have become unpatentable because novelty was destroyed. This is why the 12-month deadline must be tracked carefully and the complete specification prepared well in advance.
Does a provisional patent give any legal protection?
A provisional application does not grant any patent rights or legal protection against infringement. It establishes a priority date — ensuring that anyone who files for the same invention after your provisional filing date cannot use their later filing date to challenge your priority. Actual patent rights — the right to exclude others from making, using and selling the invention — are only granted after a complete application is filed, examined and the patent is granted.
Can I use the term "Patent Pending" after filing a provisional application?
Yes. Once a provisional patent application is filed and an application number is received from the Indian Patent Office, you may use the terms "Patent Pending" or "Patent Applied For" in relation to the invention on products, packaging, websites and marketing materials. This notifies competitors and the public that a patent application is in process, which may deter copying and have commercial signalling value even before the patent is granted.
