IP5

What IP5 does

IP5 (five IP offices) is an intergovernmental cooperation forum comprising the five largest intellectual property offices in the world: the European Patent Office (EPO), Japan Patent Office (JPO), Korean Intellectual Property Office (KIPO), National Intellectual Property Administration of China (CNIPA), and United States Patent and Trademark Office (USPTO). Together these offices handle approximately 90% of the world's patent applications and 95% of all work carried out under the Patent Cooperation Treaty (PCT). The forum was established at the first IP5 Heads of Office meeting in 2006 and has operated continuously since October 2008 to harmonise patent examination environments and standardise information sharing.

The core technology platform consists of shared interoperability and work-sharing tools. Global Dossier provides unified access to file wrappers of IP5 patent family members across all five offices. The Common Citation Document (CCD) consolidates prior-art citations, while the One Portal Dossier (OPD) enables secure examiner-to-examiner exchange of dossier information between offices. Additional infrastructure includes the Common Application Format (CAF) for standardised filings, Priority Document Exchange (PDX/DAS) for electronic priority document transfer, IP5 Authority Files, and integration with WIPO CASE. Work-sharing initiatives include the IP5 Patent Prosecution Highway (PPH), Collaborative Search and Examination (CS&E), and classification harmonisation under Working Group 1 (CPC, FI, IPC). The Patent Harmonisation Expert Panel (PHEP) drives procedural alignment, and a NET/AI task force coordinates exploration of machine translation and automatic classification.

IP5 does not generate revenue and does not charge fees for its services. The forum is funded and resourced indirectly through the budgets of the five member offices, each operating under its own national or international legal framework. The EPO manages the IP5 website on behalf of the five offices. IP5's customer base consists of patent applicants — companies, inventors, and researchers filing globally — who benefit from reduced duplication of examination work, faster prosecution via PPH, and harmonised procedures. Industry consultation engages six major IP associations (AIPLA, BUSINESSEUROPE, IPO, JIPA, KINPA, PPAC) to inform policy direction.

Core offering

IP5 is an intergovernmental cooperation framework of the five largest patent offices (EPO, JPO, KIPO, CNIPA, USPTO) that coordinates patent practices, statistics and shared information services. The forum develops and operates shared technology platforms such as Global Dossier, the Common Citation Document, One Portal Dossier and the IP5 Patent Prosecution Highway to harmonize patent examination and reduce duplication of work. IP5 collectively handles approximately 90% of the world's patent applications and 95% of all Patent Cooperation Treaty (PCT) work.

Product overview

IP5 (Five IP Offices) is a forum of the five largest intellectual property offices in the world - EPO, JPO, KIPO, CNIPA, and USPTO - established to improve the efficiency of the global patent examination process. IP5 collectively handles about 90% of the world's patent applications and 95% of all PCT work. The IP5 ecosystem consists of collaborative platforms including Global Dossier (providing unified access to patent file wrappers across all five offices), the Common Citation Document (CCD) for consolidated citation data, the IP5 Patent Prosecution Highway (PPH) for fast-track examination, Collaborative Search and Examination (CS&E) for joint PCT searches, the Common Application Format (CAF) for standardised filings, and Priority Document Exchange (PDX/DAS) for electronic priority document sharing. These are supported by harmonisation initiatives through the Patent Harmonisation Expert Panel (PHEP), classification work through Working Groups, authority files, patent information policies, and comprehensive statistics reporting. The IP5 also maintains an Industry Consultation framework engaging with major IP associations worldwide.

Functional benefit

Products and services

• Global Dossier Provides access to file wrappers of IP5 patent family members in a single location, allowing applicants and examiners to view file wrapper documents from any IP5 office along with alerting and standardized XML data.
• Common Citation Document (CCD) Single point access to up-to-date citation data relating to patent applications of the IP5 Offices, consolidating prior art cited by all participating offices for family members of a patent application.
• IP5 Patent Prosecution Highway (IP5 PPH) Fast-track patent examination programme that allows applicants to obtain patents faster and more efficiently by leveraging work products from other IP5 Offices, based on PCT work products or national work products.
• Collaborative Search and Examination (CS&E) Pilot programme testing a collaborative approach to international searches under the PCT, allowing examiners from different regions and with different language capabilities to work together to produce one high-quality international search report.
• Common Application Format (CAF) Standardised format for descriptions, claims, abstract and drawings across IP5 Offices that reduces the burden on applicants to re-draft specifications according to each country's format requirements.
• Priority Document Exchange (PDX/DAS) Electronic exchange of priority documents between IP5 Offices, including integration with the WIPO Digital Access Service (DAS), significantly reducing burden on applicants as offices can exchange priority documents without intervention by the applicant.
• IP5 Authority Files Definitive lists of all patent documents issued by each IP5 patent office, enabling patent offices and third-party patent information providers to assess completeness of their collections.

• Questel (Orbit Intelligence): Global IP intelligence and patent search platform providing prior art, family, and citation data overlapping with the IP5 Common Citation Document. Comparable as a commercial alternative/supplement to IP5 information services.

Others

• European Patent Office (EPO): One of the five IP5 member offices and the host of the IP5 website. Comparable as a regional patent granting authority and as a co-developer of Global Dossier, OPD, and shared classification tools.
• USPTO (United States Patent and Trademark Office): IP5 member office and largest national patent office by filings. Comparable as both a peer and a partner, contributing file wrapper data to Global Dossier and driving inter-office document sharing workstreams.
• CNIPA (National Intellectual Property Administration of China): IP5 member office, the largest by application volume. Leads the Global Dossier legal-status workstream and a co-developer of harmonized citation and classification infrastructure.
