IP Index: Global Patent Systems Hold—But Major Cracks Emerge

The U.S. Chamber’s 2026 International IP Index offers a comprehensive roadmap for strengthening patent protection and enforcement worldwide. This year’s Index evaluates the IP frameworks of 55 global economies across 53 unique indicators, representing over 90% of global GDP. The findings highlight both progress and persistent challenges in securing effective patent systems globally.

The foundation is holding…for now: In the 2026 report, 23 economies achieved 70% or more of the available score, with Singapore, Japan, South Korea, Switzerland, and the United States leading the top five in the patent rankings.

But warning signs persist: While many economies maintain their patent frameworks, there are growing cracks in patent protection in historically strong markets. The result is an increasingly uneven global landscape for innovation.

While the United States retains one of the world’s strongest patent environments, continued threats to expand march-in-rights and the imposition of most favored nation pricing (MFN) creates uncertainty that could jeopardize future breakthroughs.

In the European Union, the General Pharmaceutical Legislation expands the Bolar exemption to pre-commercial and commercial activities, which undermine patent enforcement in the EU. This weakens long-standing incentives for biopharmaceutical R&D in Europe and risks driving life sciences investment elsewhere.

Trouble with trade: While trade agreements can enhance IP protection, our trading partners must effectively implement their IP commitments to achieve the benefits strong IP systems provide. The IP Index highlights where Canada and Mexico face implementation challenges tied to the USMCA.

Canada’s patent term adjustment mechanism remains largely ineffective, providing minimal relief for applicants facing long delays.

Mexico introduced a new patent linkage arrangement in 2025, but key weaknesses—such as the absence of early notification and a mere 10day response period—mean it still falls short of USMCA requirements.

Why it matters: When governments strengthen patent protection and enforcement, economies are better positioned to capture the full socio-economic benefits of innovation.

Predictable patent regimes attract greater R&D investment, support advanced biopharmaceutical and tech development, and accelerate the delivery of new products to market.

Conversely, reforms that weaken exclusivity slow innovation, increase market uncertainty, and deter investment in next-generation breakthroughs.

The takeaway: Countries that reinforce stable, high standard patent environments will be best positioned to lead in the innovations that shape the future. These countries, including global standard bearers, must recommit to enhancing their patent regimes to ensure the innovation ecosystem thrives.
