Provisional vs Non-Provisional Patent Applications
Choosing between a provisional and a non-provisional application is the first real fork in the road, and picking wrong changes both your costs and your timeline.
A provisional application locks your filing date for twelve months but never becomes a patent on its own. A non-provisional application is the real thing, the one examiners actually review.
Provisional at a glance
- Lower cost and simpler to file
- Gives you a priority date without formal claims
- Expires after one year if not converted
- Lets you test the market before committing
Non-provisional at a glance
- Requires full specification and formal claims
- Triggers the official examination process
- Is what ultimately issues as a granted patent
- Costs more in fees and attorney time
Many inventors start with a provisional to secure the date, then convert when funding or market interest confirms the idea is worth protecting.
Which should you choose
If you need time to raise money or validate the market, a provisional buys you a year at low cost.
- Provisional first when unsure
- Convert when the idea proves out
- Never let the year lapse by accident
