Introduction
Filing a patent application is a crucial step for protecting your invention. However, the type of application you choose — Provisional, Non-Provisional, or PCT — will significantly affect your timeframe, costs, and legal leverage. Making the wrong decision can lead to missed markets and lost protection.
Real-World Example
A startup founder once filed only a U.S. Provisional Application, thinking they could expand globally later. A year passed, and they tried to file in Europe and Asia — only to discover they had missed the legal window. Their innovation remained unprotected in key markets.
This article aims to clear up the differences between the three main types of patent applications, explain when to use each one, and help you make a confident, strategic choice for protecting your invention globally.
1. Types of Patent Applications Explained
Provisional Application – The “Soft Launch” (U.S. Only)
A Provisional Patent Application (PPA) is a flexible, cost-effective way to secure an early filing date in the United States.
Why file it? To lock in your invention date while you refine your product or prepare for funding.
Non-Provisional Application – Full Protection in the U.S.
This is the standard route to obtaining a granted U.S. patent.
Why file it? To begin the official examination process and secure enforceable rights in the U.S.
PCT Application – The Global Gateway
The Patent Cooperation Treaty (PCT) allows you to file one application and preserve rights in over 150 countries.
Why file it? To delay the costs and decisions of national filings while exploring markets or raising capital.
2. When to Choose Which Application
In other words, if your product is fully developed and you’re ready to file, you should go for a Non-Provisional application in the U.S., and/or a PCT application if you want broader protection.
If the product isn’t ready yet but you want to secure your filing date and buy some time, choose a Provisional application.
If you already know you want protection in Europe, Asia, or multiple countries from the start, file a PCT or Non-Provisional directly in the target countries.
If you’re unsure about your final markets but want to keep global options open, start with a Non-Provisional, then file a PCT within 12 months.
3. Common Mistakes to Avoid
- Don’t Miss Provisional Deadline
If you don’t convert a Provisional into a Non-Provisional within 12 months, you lose your priority date. - U.S. Only Filing, Too Late for PCT
Filing only in the U.S. and waiting more than 12 months means you’ll lose access to the PCT route. Use iPNOTE to get reminders so you don’t miss the deadline to file your PCT application on time. - Underestimating PCT Costs
Filing PCT is only the beginning. National phases cost thousands per country. Plan your budget accordingly.
4. Comparison Table: Timing, Cost, Applicability, Risks
Ask yourself these key questions to choose the right type of patent application:
1. Do you have a working prototype or concept but need to secure a filing date quickly and affordably?
File a Provisional Application. It’s low-cost, requires minimal formatting, and gives you 12 months to refine your invention and prepare a formal submission.
2. Is your invention finalized and you’re ready to seek full legal protection in the United States?
File a Non-Provisional Application. This starts the official patent examination process and puts you in line for enforceable rights.
3. Are you considering patent protection outside the U.S. within the next 2–3 years?
File a PCT Application within 12 months of your initial (Provisional or Non-Provisional) filing to preserve global rights while delaying high international costs.
4. Is your priority getting a patent granted in the U.S. as soon as possible, without delay?
File a Non-Provisional directly. Skipping the Provisional saves time and puts you into the USPTO review queue immediately.
5. Do you want to protect your invention globally, but aren’t sure yet which countries to choose?
Use the PCT route. It buys you time up to 30 or 31 months to make informed decisions and raise funds before national filings.
6. Are you unsure if your invention is ready, but want to protect it while testing the market or talking to investors?
Start with a Provisional. It gives you flexibility and secures your priority date without committing to the full expense of a Non-Provisional or PCT.
7. Have 12 months passed since your Provisional was filed?
Act now. You must file a Non-Provisional or PCT before the 12-month deadline to maintain your priority and avoid losing protection.
Always track deadlines:
- Provisional to Non-Provisional: 12 months max
- PCT to national phase: ~30/31 months depending on country
