Overview

3 Strategic Reasons to File a Provisional Application Today

A provisional filing is not a compromise — it is smart IP strategy used by the world's most innovative companies and individual inventors alike. India's patent system is first-to-file — the date of your first patent filing determines who has superior rights when two parties claim the same invention. Filing a provisional today means your priority date is today, regardless of when your complete specification is filed (within 12 months).

After filing, you can use "Patent Pending" on your product and in investor discussions. This signals that your invention is protected and deters copying. Provisional filings also allow you to safely disclose to investors, manufacturers, and partners who may previously have required an NDA before hearing the invention.

💡

Every Day You Wait is a Day a Competitor Could File First

In India — and globally — the patent system is first-to-file. Whoever files first owns the priority date, regardless of who invented first. TaxClue files your provisional in 2–3 days.

FAQ

Frequently Asked Questions

India does not have a grace period for public disclosures — any disclosure before the filing date can be used as prior art against your application. However, if the disclosure was recent and not yet indexed in patent databases, filing a provisional immediately is the best course of action to secure whatever priority rights remain.
New features not described in the provisional can be added to the complete specification, but they will only get priority from the complete specification filing date — not the provisional filing date. Only subject matter disclosed in the provisional gets the earlier priority date.
The provisional is deemed abandoned and the priority date is permanently lost. There is no provision for extension. The only remedy is to file a fresh application — but your priority date is now the new filing date, and any disclosures made in the interim may count as prior art against you.
The provisional must describe the invention in enough detail that the complete specification can relate back to it. TaxClue writes provisionals with the complete specification in mind — capturing multiple embodiments, alternative implementations, and enough technical detail to support broadly-drafted claims later.
