The Patent Treaty is an international treaty that includes more than 150 states contracting to make it easier to seek patent protection for an invention in more than one country simultaneously. The protection can be obtained by filing an international patent application. This single application replaces all the separate patent applications filed at the national and regional levels. However, the authority to grant this protection remains in the hands of the national and regional offices.
The Patent Cooperation Treaty was introduced in the 1970s for a streamlining and economical procedure for patent application filing in numerous countries. With the increasing scope and value of patent protection, the treaty brought much leverage to the businesses opting for patent protection.
The Patent Cooperation Treaty simplifies the management of the international patent system, with these advantages:
Only the utility patent can be obtained by the process of PCT patent application. It does not cover the design patents. Under this process, the application is sourced from all the contracting states to a single point. Therefore, there is a delay in the procedure due to the workload. However, PCT provides 18-19 months to select the country of interest. It is also costlier as the prosecution of applications requires prosecution in each country. There are certain drawbacks of the Patent Cooperation Treaty, but that is negligible before the advantages it offers. However, every year, amendments are made to the PCT system to ensure the alignment with the applicant's interest and the national patent offices in respective countries.
