A provisional patent application allows you to establish a priority date for your invention before the complete specification is ready. It gives you 12 months to develop your invention fully, conduct commercial testing, and file the complete specification — while your priority date is protected.
Key Benefits
- Establishes priority date immediately — critical for "first to file" system
- Gives 12 months to develop invention and file complete specification
- Lower cost than complete specification — buy time commercially
- Can use "Patent Pending" notice from filing date
- Allows you to test market response before full investment
Provisional vs. Complete Application

| Examination | No | Yes |
| Duration of protection | 12 months only | 20 years |

⚠️ You must file the Complete Specification within 12 months of the provisional filing date. Missing this deadline abandons your application and loses your priority date permanently.
