Patent Cooperation Treaty: Path Optimization for the Global IP Landscape

You've secured your innovation at home, but what about the rest of the world? The last thing you should do is hastily file costly international patent applications. The Patent Cooperation Treaty (PCT) lets you take a strategic pause to identify the costs associated with exploring various frontiers in the IP landscape. Global IP strategy can be seen as a mapping problem where you chart the boundaries of your IP protection.

You can visualize your IP rights as a map indicating the countries you have IP protection in, the countries in which you can pursue IP protection, and those you cannot. The countries where you can still pursue IP protection are the frontier, and the PCT gives you time to decide the optimal path forward.

At Bright-Line IP, we've guided numerous innovators—from scrappy startups to multinational giants—through the complex process of navigating international patent laws. Here, we explain why the PCT is an indispensable tool for streamlining that process.

PCT Basics: Your Strategic Pause

• The PCT is an international treaty that provides a unified filing procedure for patent applications in over 150 member countries. [1].

• The PCT gives you up to 30 months from your earliest filing date to select your target countries. [2].

• PCT applications must be filed within 12 months of the earliest filing date. [1].

• The PCT results in a non-binding opinion by the international search authority, providing applicants with valuable insight into how international patent examiners will evaluate their invention.

• The PCT must be followed by applications with the patent offices of your target countries to obtain actual patent rights. These national stage applications may be filed in multiple countries simultaneously.

• The PCT is a vehicle to defer the cost of national stage applications while fundraising and validating markets.

PCT Timeline: A Step-by-Step Guide

1. File Locally: Start with a patent application in your home country. (0 months)

2. Go International: Within 12 months, file your PCT application. (0-12 months)

3. Get Feedback: Receive an International Search Report (ISR) and written opinion on your invention's patentability. (16-17 months)

4. Publish: Your application is published 18 months after the earliest priority date. (18 months)

5. Optional Review: You can request a more detailed patentability analysis. (18-28 months)

6. Make Your Move: Decide which countries to enter for national stage examination. (30 months) [2].

Flexibility is Key: Optimizing Your Application

A key benefit of the PCT is flexibility. The PCT offers an optional review as a chance to respond to the ISR through procedures outlined in articles 19 and 37.

• Article 19 is used for modifying claims alone, and must be filed within the later of two months after the ISR is issued or 16 months from the priority date. [3].

• Article 37 enables more substantive changes to the application and can be filed up to 28 months after the earliest filed priority date. [4].

The PCT gives you flexibility to address issues in the application before entering the national stage, or to take a wait and see approach where you address issues identified by national stage examiners.

National Stage: Navigating the Global Frontier

• Timing is Everything: Most countries require national stage entry within 30 months from your earliest filing date. Miss this deadline, and you could lose rights in that country.

• One size has never fit all: Each country has its own requirements. You might need translations, local representatives, or specific formalities.

• Check for PCT filing benefits: Many countries - including the U.S. - grant accelerated national stage examination if the ISR includes a favorable opinion.

• Budget Wisely: National stage entries can be expensive, especially if entering multiple countries. Plan ahead and prioritize your markets.

At the national stage, your PCT transforms into a set of patents filed in your chosen countries. National stage applications are independently examined. If each country’s patent office issues a unique rejection citing unique prior art, you’ll have to draft unique arguments in response to each country’s examiner. Hiring experienced patent professionals who can coordinate a team of foreign agents when implementing a global IP strategy is essential.

Leveraging the Patent Prosecution Highway (PPH)

The Global PPH Program grants accelerated examination of patent applications in 27 national/regional offices based on favorable PCT results. [5]. Consider requesting an optional review of the ISR as a way to position your PCT to capitalize on PPH programs. International patent laws can be complex, at Bright-Line, we give you the guidance you need to make informed decisions about your global IP strategy.

PCT Best Practices: A Quick Checklist

1. Start Early: Begin planning your national stage strategy well before deadlines approach.

2. Stay Flexible: Use the PCT period to assess market potential and adjust your strategy.

3. Leverage Expertise: Work with experienced IP professionals who understand the nuances of different jurisdictions.

4. Review and Refine: Before entering national stages, review your application for potential improvements or amendments.
