Provisional Patent Filing —
Lock Your Priority Date
Before Anyone Else Does
Your invention is at risk the moment you disclose it — to a co-founder, investor, or manufacturer. A provisional patent application filed today establishes your priority date and gives you 12 months to refine the invention, find funding, and file the complete specification. Filed within 2–3 days by TaxClue's registered patent agents.

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.
