PCT, or Patent Cooperation Treaty, is an international treaty that makes it easier to file patents in multiple countries. Its role is to simplify the process for inventors who want to protect their inventions in several countries without having to file separate patent applications in each country.
Here’s how the PCT works:
In short, the PCT system makes it more efficient and cost-effective for inventors to protect their inventions globally, streamlining the process of filing patents internationally.
Here’s how the PCT works:
- International Application: The inventor files a single application (called a PCT application) through their national patent office or directly with the World Intellectual Property Organization (WIPO). This application is recognized in all PCT member countries (currently over 150 countries).
- International Search: The PCT system includes an international search that helps determine whether the invention meets the basic criteria for patentability (novelty, inventive step, etc.). This saves the inventor time and money in evaluating whether the invention is likely to be granted a patent.
- National Phase: After the international process, the inventor can choose in which countries they wish to seek patent protection. They then enter the "national phase" and file the application with each selected country's patent office. This is done based on the results of the international search.
In short, the PCT system makes it more efficient and cost-effective for inventors to protect their inventions globally, streamlining the process of filing patents internationally.
