EPO Receives Record 201,974 Patent Applications in 2025 — AI and Quantum Tech Drive Growth as China Surpasses Japan

The European Patent Office (EPO) announced on April 13, 2026 that patent applications received in 2025 exceeded 200,000 for the first time in the office’s history. According to the EPO Technology Dashboard 2025, total applications reached 201,974 — a 1.4% increase from 2024, and a milestone that underscores Europe’s continued competitiveness as a global innovation hub.

The headline figure reflects a sustained demand for European patent protection, with three technology sectors standing out in terms of growth rates. AI and machine learning-related filings rose by approximately 10% year-on-year. Quantum technologies recorded the highest growth rate across all fields at 38%, while digital communications increased by 11%. These sectors represent the core battlegrounds of next-generation industrial competition, and the surge in filings reflects the urgency with which companies are securing rights in the European market ahead of commercial deployment.

EPO 2026 Guidelines

In terms of country of origin, the United States retained its position as the largest filer, followed by Germany in second place. The most significant shift was China’s rise to third place, overtaking Japan for the first time. Chinese applicants filed 22,031 applications in 2025, a 9.7% increase from the prior year. Huawei, which has consistently ranked among the top applicants, has been driving a broad-based push across 5G successor technologies, AI hardware, and related software claims. Japan fell to fourth place, though Toyota, Sony, and Canon remained prominent among the top filers globally.

Among individual applicants, Samsung maintained the top position, followed by Huawei and LG. Nokia’s return to prominence was the most notable development in the top-ten rankings: the Finnish telecoms company climbed from 12th place in 2024 to 5th in 2025, reflecting aggressive investment in 6G and advanced wireless protocol patents. From a standard essential patent (SEP) licensing perspective, Nokia’s improved ranking has direct implications for the company’s negotiating leverage in future FRAND licensing discussions.

The record filing numbers come against a backdrop of structural changes in European patent law. The Unified Patent Court (UPC) and unitary patent system, which entered into force in June 2023, have been cited as factors enhancing the attractiveness of European filings. Under the unitary patent system, a single granted EPO patent can provide protection across the participating EU member states without requiring validation in each country individually. For multinational companies in particular, the UPC reduces the cost and complexity of European patent enforcement, which may be contributing to the sustained growth in filings from non-European applicants including those from the US, China, and Japan.

The patentability of AI-related inventions at the EPO continues to be governed by the requirement that an invention must have a “technical character” — meaning it must produce a technical effect that goes beyond the normal physical interactions of software running on hardware. This standard, which the EPO has applied consistently, has shaped the form in which AI-related applications are drafted. Applicants seeking European protection for AI systems typically frame their claims around specific hardware architectures, sensor integrations, or industrial process optimizations rather than abstract algorithmic methods. The rise in AI filings suggests that applicants are becoming increasingly adept at navigating these requirements.

The 38% growth in quantum technology patents reflects anticipatory patenting behavior: the commercial viability of quantum computing remains limited, but companies and research institutions are establishing early intellectual property positions in quantum hardware, quantum sensing, and quantum cryptography. IBM, Google, and a growing number of European and Japanese research institutions are among those actively filing in this space, laying the groundwork for future commercialization and potential licensing positions.

For Japanese IP practitioners and corporate patent counsel, China’s rise to third place in EPO filings is a development that warrants close attention. Japan’s absolute filing numbers have not declined sharply, but the relative gap in filing volume and growth rate between Japanese and Chinese applicants in Europe continues to widen. The strategic question this raises is whether Japanese companies’ European filing strategies are keeping pace with the competitive pressure from Chinese counterparts, particularly in AI, quantum, and advanced materials — fields that are increasingly central to Japan’s industrial competitiveness.

The EPO has indicated it will continue expanding examination capacity in collaboration with the UPC framework and investing in examination efficiency measures to address the growing volume. For IP professionals tracking the European patent landscape, the 2025 data confirms that European filings remain a priority for leading technology companies worldwide, and that AI and quantum technology are reshaping the geography of innovation as captured in patent statistics.
