Provisional Patent in India
Provisional patent application in India: secure a priority date for 12 months, then file a complete specification. Registered patent agents at DuxLegis.
What a provisional patent application does
A provisional patent application in India secures an early filing (priority) date while you refine the invention. Within twelve months you must file a complete specification with claims, or the provisional lapses for grant purposes.
Startups and R&D teams use provisionals before demos, publications, or fundraising so public disclosure does not destroy novelty.
Drafting quality still matters
A weak provisional that omits key embodiments can limit claim scope later. DuxLegis registered patent agents draft provisionals with enough technical detail to support the eventual complete specification and, where planned, PCT filings.
We also advise when a complete specification should be filed first instead of a provisional.
Next steps after provisional filing
Track the twelve-month deadline, continue R&D documentation, and decide on India-only complete filing versus PCT. Cost planning should include complete drafting and examination fees.

Frequently asked questions
Is a provisional patent a granted patent?
No. It is a temporary filing that must be followed by a complete specification within twelve months to pursue grant.
Can I say “patent pending” after a provisional?
Yes, once a provisional or complete application is filed, subject to accurate marketing claims.
What happens if I miss the 12-month deadline?
The provisional generally cannot support grant; a new filing may be needed and novelty may be lost if disclosure occurred.
