Provisional patent application in India
A provisional application secures an early filing date while you finish developing the invention.
Quick answer
A provisional application gives you a filing date for an invention that is not fully ready. You must file the complete specification within 12 months, or the application is deemed abandoned. It is not examined and does not by itself become a patent.
What it does and does not do
- It fixes an early priority date, which helps against later filers.
- It gives you a year to test, improve and look for funding.
- It is not published or examined, and it does not grant any rights by itself.
- Whatever is not described in it may not get the early date, so describe the invention as fully as you can.

When to use it
- The invention works but details or data are still missing.
- You need to show it to investors or customers and want a date on record first.
- You want to test the market before paying for a complete filing.
Converting to a complete application
File the complete specification within 12 months of the provisional filing date, claiming its priority. See the patent process and fees for the next steps.
Frequently asked questions
Can I use "patent pending" after a provisional filing?
People commonly do, but it gives no enforceable right. Use it carefully and do not imply a granted patent.
What if I miss the 12 months?
The provisional application is treated as abandoned and the priority date is lost.
Is a provisional application cheaper?
The government fee is the same basic filing fee. Drafting is usually lighter, but a poor provisional can hurt you later.
