IP Five in 5: 2026’s Biggest Shifts in Global Patent Strategy

March 10, 2026

The global patent landscape is evolving quickly. From regulatory changes to new digital infrastructure and accelerated examination pathways, 2026 is already shaping how innovators protect and manage intellectual property worldwide.

For corporate IP teams and innovation leaders, keeping up with these developments is critical. Policy updates from major patent offices can influence filing strategies, prior art analysis, prosecution timelines, and global portfolio management decisions. In this edition of IP 5 in Five, we highlight five important developments that are shaping global patent strategy in 2026 and what they mean for companies managing international patent portfolios.

1. New PCT Rules Expand the Scope of International Patent Searches

Significant amendments to the Patent Cooperation Treaty (PCT) regulations came into effect on 1 January 2026, expanding the scope and depth of international patent searches.

The updates revise several key provisions, including PCT Rules 34, 36, and 63, which define the minimum documentation that International Searching Authorities (ISAs) must consult when conducting prior art searches.

The revised rules introduce several important changes:

19 new national patent collections have been added to the required search documentation
Updates to ISA and International Preliminary Examining Authority (IPEA) eligibility requirements
Enhanced access to global patent data during international searches

Another important revision affects PCT Rules 33 and 64, which now broaden the definition of relevant prior art to include non-written disclosures.

In addition, international patent offices will now exchange full-text patent applications rather than image-based formats, improving search quality and data accessibility. For applicants, these updates mean more comprehensive prior art searches and improved transparency in international patent examination.

2. IP5 Patent Prosecution Highway Extended Through 2029

The IP5 offices representing the world’s five largest patent authorities have agreed to extend the Patent Prosecution Highway (PPH) pilot program for another three years.

The program will now continue from 6 January 2026 through 5 January 2029.

The IP5 offices include:

China National Intellectual Property Administration (CNIPA)
European Patent Office (EPO)
Japan Patent Office (JPO)
Korean Intellectual Property Office (KIPO)
United States Patent and Trademark Office (USPTO)

The PPH program allows patent applicants to accelerate examination in participating jurisdictions by relying on work already completed by another patent office.

For example, applicants can use:

Written Opinions from the International Searching Authority (WO-ISA)
International Preliminary Examination Reports (IPERs)

to request expedited national patent examination. For global innovators managing multi-jurisdiction patent portfolios, PPH programs remain one of the most effective ways to reduce prosecution timelines and streamline international filings.

3. EPO and IP Australia Launch New PCT Search Pilot

In another step toward stronger international cooperation, the European Patent Office and IP Australia have announced a two-year PCT pilot program starting 1 March 2026.

Under the initiative, Australian applicants will be able to designate the EPO as their International Searching Authority (ISA) and International Preliminary Examining Authority (IPEA) when filing international patent applications.

This option will be available for:

applications filed with IP Australia
applications filed through WIPO’s International Bureau

For applicants, this offers several potential advantages:

access to EPO’s highly regarded search reports
potential cost efficiencies
faster alignment with European patent protection strategies

The collaboration reflects a broader trend among patent offices toward greater international harmonization and shared examination resources.

For companies targeting global markets, such initiatives can help simplify international patent strategies.

4. EPO Completes Transition to Online Filing 2.0

The European Patent Office has officially retired its long-standing eOLF desktop filing software, replacing it with Online Filing 2.0 (OLF 2.0) as the standard platform for submitting patent applications.

The move supports the EPO’s Strategic Plan 2028, which aims to create a fully digital patent-granting process by 2027.

Key aspects of the transition include:

eOLF software has been permanently discontinued
Online Filing 2.0 is now the default system for patent submissions
The platform provides a secure browser-based filing environment
Additional procedural requests can be submitted through MyEPO

The change reflects a broader shift across global patent offices toward digital-first patent administration.

For corporate IP teams and law firms, these digital platforms improve workflow efficiency while reducing administrative complexity.

5. USPTO Launches SPARK Program to Support Standards Innovation

The United States Patent and Trademark Office has introduced the SPARK Pilot Program, a new initiative designed to increase participation in standards development organizations (SDOs).

The program targets:

small and medium-sized businesses
universities
non-profit organizations

Eligible participants who make meaningful contributions to technical standards can receive acceleration certificates, which may be used to:

expedite patent examination
fast-track Patent Trial and Appeal Board (PTAB) appeals

SPARK is the first program launched under the USPTO’s Standard Essential Patent (SEP) Working Group, which aims to strengthen U.S. participation in global technology standards. By lowering resource barriers for smaller innovators, the initiative could help expand participation in areas such as telecommunications, AI, and emerging technologies.

What These Developments Mean for Global Patent Strategy

Taken together, these updates reflect several broader trends shaping the future of intellectual property management:

1. Expanding access to global prior art data

New PCT rules are strengthening international patent searches and improving transparency.

2. Continued emphasis on accelerated examination

Programs like the Patent Prosecution Highway remain critical tools for reducing the time to patent grant.

3. Greater international collaboration

Initiatives between offices such as the EPO and IP Australia demonstrate a growing push toward cross-border cooperation.

4. Rapid digital transformation of patent offices

The transition to online filing systems highlights the move toward fully digital IP administration.

5. Stronger connections between patents and technology standards

Programs like SPARK emphasize the increasing importance of standard-essential patents in global innovation ecosystems. For companies managing large global patent portfolios, these shifts reinforce the importance of modern IP management infrastructure and data-driven portfolio strategy.

Key Takeaway

Global patent systems are becoming more digital, more collaborative, and more data-driven. For innovation-driven organizations, staying ahead of regulatory changes and filing strategy developments is essential to protecting intellectual property and maintaining competitive advantage.
