The Patent Cooperation Treaty (PCT) is a global framework administered by the World Intellectual Property Organization (WIPO) that simplifies the process of filing patent applications across multiple countries. Instead of submitting separate applications to each national patent office, applicants can file one international patent application under the PCT system.
This unified procedure does not itself grant a patent. Instead, it provides a structured path for applicants who intend to seek patent protection in multiple countries while delaying the costs and complexity of filing in each jurisdiction.
The treaty originated from the Washington Diplomatic Conference in 1970 and now includes over 150 contracting states, forming part of the broader international patent system.
How the Patent Cooperation Treaty System Works
The patent cooperation treaty system divides the process into two main stages:
1. International Phase
During the international phase, the applicant files a single PCT application with a receiving office, which may be a national or regional patent office.
Key steps include:
Filing the International Application
Establishes the filing date and priority date
Must follow the required form prescribed under the treaty
International Search
Conducted by an International Searching Authority (ISA)
Produces an international search report identifying prior art
Includes a written opinion on patentability
International Publication
The application is published by the International Bureau of WIPO
Typically occurs 18 months from the earliest priority date
Optional Supplementary International Search
Helps identify additional relevant prior art
International Preliminary Examination (Optional)
Conducted by an International Preliminary Examining Authority (IPEA)
Results in an international preliminary examination report or international preliminary report
This phase helps applicants evaluate whether their claimed invention meets basic patentability standards before entering national jurisdictions.
2. National Phase
After completing the international phase, applicants must enter the national phase or regional phase in each country or region where they want protection.
This involves:
Filing with each designated office or elected office
Complying with national law requirements
Paying local fees and handling translation costs
Submitting required documents within the prescribed time limit
Each national office or regional patent office then independently examines the application based on its own laws and standards.
