Patent Cooperation Treaty (PCT) Explained

The Patent Cooperation Treaty (PCT) offers inventors a way to protect their ideas in multiple countries with a single patent application. It was created in 1970 and operates under the World Intellectual Property Organization (WIPO). As of today, over 150 countries have joined the treaty.

Traditionally, inventors had to file separate applications in each country. As a result, the process became expensive, time-consuming, and repetitive. Fortunately, the PCT simplifies this burden by offering a unified procedure for global patent filing.

How the PCT Works

The PCT process takes place in two major phases: the international phase and the national phase.

1. International Phase

First, inventors file one international application through their local patent office or directly with WIPO. Then:

• An International Searching Authority (ISA) conducts a search for prior art.
• The ISA issues a report that helps inventors evaluate the novelty and technical merit of the invention.
• Additionally, inventors can request an international preliminary examination for further clarity on patentability.

This phase gives inventors time to understand the potential value of their invention before entering multiple countries.

2. National Phase

After about 30 months, inventors must decide where they want protection. At this stage:

• They file applications in each desired country or region.
• Local patent offices examine the application according to their own laws.
• If approved, the patent is granted in that jurisdiction.

Therefore, the national phase allows countries to maintain control over their patent systems, while still benefiting from international cooperation.

Benefits of the PCT

The PCT offers several practical benefits:

• Simplified Process: One application replaces multiple early-stage filings.
• Strategic Planning: Inventors gain time to assess markets, investors, and legal strategy.
• Cost Efficiency: The unified system delays translation and legal expenses.
• Legal Insight: International reports help improve patent claims before national entry.
• Global Reach: Small businesses can compete on the world stage more easily.

Moreover, the PCT system supports innovation by making international patent protection more accessible and efficient.
