PCT application is a method of applying for patents in multiple countries with a single application based on an international treaty, with the filing date recognized uniformly in designated countries. This provides an efficient procedure where you can submit a PCT application to the patent office of your country of origin or residence and then enter the national phase in desired countries within a specified period.
On the other hand, individual country application is a method of filing separate patents in each country, often referred to as the 'Paris route'. This method requires meeting the patent requirements of each country individually and follows different procedures for each country. It is suitable when protection is desired only in specific countries, or when customized patent protection is needed for each country.
For design rights, international design application under the Hague Agreement allows simultaneous registration of designs in multiple countries with a single application. This saves time and costs and provides an efficient system to secure design rights without having to file separately in each country. However, if the number of foreign countries is small, it is possible to consider designating and applying for individual countries like patents rather than applying for the Hague international design application.
For trademark protection, international trademark application under the Madrid Protocol is efficient. It allows simultaneous registration of trademarks in multiple countries through a single application, unifying complex trademark application procedures and providing the advantage of fast and efficient trademark protection. However, if the number of foreign countries is small, it may be possible to consider designating and applying for individual countries like patents rather than using the Madrid international trademark application.
