The European Patent Office (EPO) has published its Annual Review 2025, revealing that European patent applications exceeded 200,000 for the first time in the organisation’s history.
The milestone reflects growing confidence in the European patent system, supported by continued investment in digital transformation, AI and more efficient patent examination processes under the Strategic Plan 2028.
The Office processed a record 418,868 patent dossiers during 2025, increasing productivity by 4% while maintaining high quality standards and improving the speed of patent searches, grants and opposition proceedings.
User satisfaction also remained high following the EPO’s largest-ever satisfaction survey, involving more than 8,000 participants. Innovation activity continued to grow across strategic sectors including digital technologies, healthcare, advanced materials and battery technologies.
AI played an increasingly important role throughout the patent granting process. The EPO expanded AI-powered tools for patent examiners, including a large language model-based enhancement to its PreSearch system, designed to improve prior art discovery while ensuring examiners retain full control over decision-making.
Additional AI-supported capabilities now assist with document analysis, advanced searches, file allocation and oral proceedings. At the same time, MyEPO continued evolving as the organisation’s central digital platform, while Online Filing 2.0 became the standard filing tool ahead of broader DOCX filing deployment.
The report also highlights the growing success of the Unitary Patent system, with SMEs, universities and public research organisations accounting for nearly half of all Unitary Patents granted to European innovators.
Alongside new innovation intelligence tools such as the Patent Standards Explorer, Digital Library and expanded Deep Tech Finder, the EPO says it is strengthening Europe’s innovation ecosystem through greater transparency, digital services and data-driven patent intelligence.
Why does it matter?
The Annual Review demonstrates how AI is becoming embedded within one of Europe’s most important innovation institutions. Rather than replacing patent examiners, AI is being deployed to improve search quality, accelerate administrative processes and strengthen decision-making while maintaining human oversight.
It also illustrates Europe’s broader strategy of combining AI adoption with digital public services, intellectual property protection and innovation policy.
Record patent demand, expanding use of the Unitary Patent and new digital tools suggest the EPO is positioning itself as a key pillar of Europe’s competitiveness in emerging technologies, particularly as global competition intensifies in AI, semiconductors, advanced manufacturing and deep tech.
