The Patent Cooperation Treaty (PCT) is an international agreement that plays a crucial role in the field of intellectual property rights, particularly in simplifying and streamlining the process of obtaining patent protection across multiple countries. In an increasingly globalized world where inventions often have commercial value beyond national boundaries, the need for an efficient international patent system becomes essential. The PCT addresses this need by providing a unified procedure for filing patent applications in multiple jurisdictions, thereby reducing complexity, duplication, and cost for inventors and businesses. The primary purpose of the Patent Cooperation Treaty is to facilitate the protection of inventions simultaneously in a large number of countries through a single application. Prior to the existence of the PCT, inventors seeking patent protection in multiple countries had to file separate applications in each country, often in different languages, complying with distinct legal requirements and timelines. This process was not only expensive but also time-consuming and administratively burdensome. The PCT eliminates much of this inefficiency by allowing applicants to file one “international application,” which has the effect of a national application in all designated member countries. Another important purpose of the PCT is to provide a system that assists applicants in assessing the patentability of their inventions before entering into multiple national procedures. Through international search and preliminary examination processes, applicants receive valuable information regarding the novelty, inventive step, and industrial
