What Happens at the 12-Month Provisional Deadline?

To preserve the benefit of a US provisional filing, you generally must file an appropriate follow-on application within 12 months and properly claim that benefit. A provisional does not automatically convert into a nonprovisional application or issued patent.

What should you prepare before the deadline?

Review the invention's current version, original disclosure, inventorship and ownership. Allow time for claims, drawings, filing documents and any international strategy rather than waiting until the final day.

Can another provisional restart the clock?

A new provisional establishes its own date for what it discloses; it does not extend the earlier provisional's priority period. Intervening disclosures and prior art may make that difference critical.

Is a missed deadline ever fixable?

Limited restoration procedures may be available when strict conditions are met. Do not rely on an exception as a planning strategy; contact a registered patent professional immediately if a deadline may have been missed.

A later application's claims receive the earlier date only when the original provisional adequately supports them and applicable requirements are satisfied. New improvements may have later effective dates.

GetQuickPatent helps prepare provisional drafts, but docketing and follow-on filing remain essential. Set reminders and arrange a professional review well before the 12-month milestone.
