PCT The PCT provides a unified procedure for filing patent applications to seek protection in multiple jurisdictions. It streamlines filing before national offices such as the United States Patent and Trademark Office, European Patent Office, Japan Patent Office, China National Intellectual Property Administration, and Canadian Intellectual Property Office, while interacting with international bodies like the World Intellectual Property Organization and the United Nations.

Overview

The system allows inventors and applicants from countries such as United States, China, Japan, Germany, France, United Kingdom, India, Brazil, Russia, South Korea to file a single international application that has effects for national offices including the Australian Patent Office, Mexican Institute of Industrial Property, Spanish Patent and Trademark Office, Italian Patent and Trademark Office, Swedish Intellectual Property Office. Major users include corporations like IBM, Samsung, Huawei, Siemens, Canon, Intel, Sony, and research institutions such as Massachusetts Institute of Technology, Stanford University, University of Cambridge, ETH Zurich, Tsinghua University. The treaty is administered by the World Intellectual Property Organization with procedural interaction with the International Bureau of WIPO and national receiving offices like the USPTO and EPO.

History

Negotiations leading to the agreement involved delegations from United States, United Kingdom, France, Germany, Japan, Soviet Union, Brazil, India, Australia, Canada and were concluded in the late 1960s and early 1970s. The treaty was concluded in Washington, D.C. and opened for signature in 1970; it entered into force following ratification by signatories including United States, Japan, United Kingdom, France, Germany, Italy, Canada. Over decades the system expanded to include accession by countries such as China, Brazil, India, Russia, South Africa, Mexico and procedural developments influenced by the European Patent Convention, bilateral accords like the US-Japan Framework, and multilateral forums such as the World Trade Organization.

Patent Cooperation Treaty (PCT) Framework

The institutional framework centers on the World Intellectual Property Organization acting alongside national receiving offices such as the United States Patent and Trademark Office, European Patent Office, Japan Patent Office and international searching authorities including the EPO and the Korean Intellectual Property Office. Legal instruments and administrative guidelines reference model provisions from the Patent Law Treaty, decisions from assemblies like the WIPO General Assembly, and harmonization efforts involving the World Trade Organization and the Organisation for Economic Co-operation and Development. Users include multinational firms such as Qualcomm, Nokia, BP, GlaxoSmithKline, Pfizer and public research entities like the National Institutes of Health, Fraunhofer Society, CNRS.

Procedures and Timeline

Applicants submit an international application through receiving offices such as the USPTO, EPO, JPO, SIPO (now CNIPA), or national patent offices like the German Patent and Trademark Office and the Indian Patent Office. The system sets timelines for international filing, including 12-month priority periods referencing earlier filings under the Paris Convention, 30-month or 31-month national phase entry deadlines influenced by national laws like those of the United States and Japan, and extensions coordinated with offices including the Canadian Intellectual Property Office and Australian Patent Office. Entities like WIPO issue forms and guidelines, while procedural interactions involve the European Patent Office acting as an International Searching Authority for many applicants.

International Search and Examination

International searches are conducted by authorities such as the European Patent Office, Japanese Patent Office, Korean Intellectual Property Office, United States Patent and Trademark Office, and China National Intellectual Property Administration. The international search report and written opinion evaluate novelty, inventive step, and industrial applicability in light of prior art including references from repositories and databases used by institutions like Google, Clarivate, Espacenet and national libraries such as the Library of Congress and the British Library. Optional international preliminary examination involves offices including the EPO and the USPTO, producing International Preliminary Reports on Patentability used by national offices such as the German Patent and Trademark Office and the Indian Patent Office.

National Phase and Enforcement

After international processing applicants enter national or regional phases before offices like the EPO under the European Patent Convention, the USPTO under the America Invents Act, the CNIPA, the JPO, and national courts such as the Federal Circuit (United States), the Supreme Court of the United Kingdom, and high courts in Germany and Japan determine enforcement and validity. Patent rights and remedies are governed by national statutes including acts like the Patent Act (United States), decisions from tribunals such as the European Patent Office Boards of Appeal, and litigation involving firms such as Apple, Samsung, Microsoft, Qualcomm, Motorola.

Impact and Criticism

The system has facilitated international patenting by applicants from United States, China, Japan, Germany, France, South Korea, India, supporting commercialization by firms like Bayer, Roche, Pfizer, Novartis, AstraZeneca and collaborative research at institutions like MIT, Oxford University, University of Tokyo. Critics include NGOs and advocacy groups such as Médecins Sans Frontières, Doctors Without Borders affiliates, scholars at Harvard University, Yale University, University of California, Berkeley who argue that patent thickets and costs disadvantage small entities and startups such as those represented by Startup America Partnership and regional incubators like Station F. Reforms discussed in bodies like the WIPO General Assembly, proposals from policy institutes such as the Brookings Institution, Cato Institute, Chatham House highlight issues including access, cost, procedural delays, and asymmetries between applicants from developed countries and developing countries.
