UK innovators filed 5,875 patent applications with the European Patent Office in 2025, down 3.3% from 6,076 in 2024, ending three years of consecutive growth. That sounds concerning. But the longer-term picture is more positive. Over the past decade, UK patent filings at the EPO have increased by 13.5%, a meaningful underlying trend that a single year’s dip does not reverse.
The technology story is genuinely encouraging. UK-based innovators filed 579 European patent applications in computer technology in 2025, maintaining the strong growth of 2023 and 2024. In AI-related sub-fields the UK recorded 29% growth, the highest increase among leading European nations. And UK innovators more than doubled their European patent filings in quantum technologies in 2025.
Oxford and Cambridge both feature in the EPO’s top 20 universities by patent applications. Some of the most commercially significant intellectual property in the world continues to originate in British labs.
The competitive context
The broader picture is less comfortable. The UK ranked ninth among countries of origin for patent applications at the EPO, behind the US, Germany, China, Japan, France, South Korea, Switzerland and the Netherlands.
China entered the EPO’s top three for the first time in 2025, filing 22,031 applications, a figure that has tripled since 2016. For comparison, the UK filed 5,875. The competitive pressure on British businesses in technology-intensive sectors is intensifying year on year.
London ranks only fifth among European cities for patent filings, behind Munich, Paris, Amsterdam and Eindhoven. For a city of its scale, its concentration of research institutions and its status as a global technology hub, that invites closer examination.
The question behind the data
Whether the UK’s relatively modest patent output reflects a funding gap, a cultural reluctance to file, or simply a different model for translating research into commercial value is genuinely open to debate.
But there is a more immediate question for businesses that are innovating. Filing a patent is only the first step. A registered patent gives you a right. It does not give you the means to enforce it.
The cost of patent litigation in the UK is substantial. A contested case in the High Court can run to over £500,000 per side before judgment. For most SMEs, that figure is simply unabsorbable, which means that in practice many registered patents go undefended not because the infringement is not real, but because pursuing it is not financially viable.
How IP insurance protects the value you have built
This is the gap that IP insurance closes. It covers the legal costs of enforcing patent rights against infringers and defending allegations of infringement, giving innovating businesses the means to protect what they have created rather than watching competitors copy it without consequence.
The UK has a strong pipeline of innovation. The challenge is ensuring that the businesses creating it have the tools to protect it.
