- Intellectual Property (IP)

1. Introduction

In 2024, the European Patent Office (EPO) witnessed a watershed moment: computer technology became its most active patent field, dethroning long-standing leaders like medical devices and transport. With 16,815 applications—a 3.3% year-on-year increase—this shift reflects the accelerating global race to dominate artificial intelligence (AI), machine learning, and quantum computing.

2. The Rise of Computer Technology (2020–2024)

2.1 Growth Trajectory

Computer technology’s ascent from third place in 2020 to the EPO’s top field in 2024 is a story of exponential innovation:

Year	Total Applications	Growth vs. Prior Year
2020	13,370	–
2024	16,815	+3.3%

2.1.1 Key Drivers:

Post-Pandemic Digitization: Remote work, telehealth, and e-commerce necessitated breakthroughs in cloud infrastructure, cybersecurity, and AI-driven automation.
AI’s Cross-Industry Relevance: From drug discovery to autonomous vehicles, AI became a universal tool. EPO data shows AI patents grew 12x between 2015 (49) and 2024 (2,243).
Policy Catalysts: The EU’s €10 billion Digital Europe Programme (2021–2027) prioritized AI R&D, while national strategies (e.g., Germany’s AI Action Plan) incentivized patent filings.

2.2 Contrasting Sectoral Trends

While computer technology thrived, other fields stagnated or declined:

Digital Communication: Fell 6.3% in 2024 as 5G standardization plateaued and R&D shifted to AI-enhanced networks.
Pharmaceuticals: Grew just 1.2%, with AI-driven drug discovery patents (e.g., protein-folding algorithms) cannibalizing traditional methods.

3. AI’s Dominance in Computer Technology

3.1 Subfield Breakdown

AI accounted for 13.3% of all computer technology patents in 2024 (2,243 applications). Its subfields reveal strategic priorities:

Subfield	Share of AI Patents (2024)	Use Cases
Bio-Inspired Computing	55.1%	Neural networks, robotics, drug design
Image/Video Recognition	31.3%	Autonomous vehicles, medical imaging
Machine Learning	9.5%	Predictive maintenance, finance
Pattern Recognition	4.1%	Fraud detection, speech analysis

3.1.1 Case Study: Bio-Inspired Computing

Siemens’ 2023 patent for a “neuromorphic chip” mimicking human brain structures reduced energy consumption in factory robots by 40%. Such innovations explain why bio-inspired computing dominates AI filings.

3.2 Regional Leaders in AI Innovation

The AI patent race is a proxy for geopolitical influence:

Region	Share of AI Patents (2024)	Key Players
EPO States	35.8%	Siemens (DE), Ericsson (SE), Bosch (DE)
United States	28.2%	Alphabet, Microsoft, Qualcomm
China	12.5%	Huawei, Tencent, Baidu
Japan	11.9%	Fujitsu, Sony

3.2.1 Europe’s Edge:

Germany’s 12.7% growth in computer tech patents was fueled by industrial AI (e.g., Bosch’s autonomous forklifts).
Switzerland’s 37.4% surge stemmed from AI applications in finance (UBS’s algorithmic trading) and pharma (Roche’s drug discovery).

3.2.2 U.S.-China Tensions:

Huawei filed 139 AI patents in 2024 despite U.S. sanctions, focusing on AI-optimized 5G base stations.
U.S. firms like Alphabet (141 AI patents) leveraged open-source frameworks (e.g., TensorFlow) to set global standards.

4. Key Players and Market Dynamics

4.1 Top Patent Applicants in Computer Technology

The 2024 rankings reveal a blend of tech giants and industrial stalwarts:

Rank	Company	Patents	Nationality	Focus Area
1	Samsung	1,097	South Korea	AI chips, consumer electronics
2	Huawei	922	China	5G-AI integration, cloud
3	Microsoft	680	US	Azure AI tools, quantum
4	Alphabet	657	US	Search algorithms, self-driving
5	Siemens	436	Germany	Industrial automation

4.1.1. Strategic Insights:

Samsung’s Vertical Integration: Its 2023 “NeuroEdge” AI chip, used in Galaxy smartphones and data centers, spawned 89 patents.
Siemens’ Industrial Pivot: 40% of its patents now relate to AI-driven predictive maintenance, a shift from legacy hardware.

4.2 Diversification of Innovation Sources

The share of patents from the top 5 applicants fell from 24.3% in 2023 to 22.6% in 2024, signaling a broader innovation ecosystem:

SMEs and Startups: Accounted for 18% of AI patents (up from 12% in 2020). Example: French startup Mistral AI filed 14 patents for natural language processing tools.
Academia-Industry Partnerships: ETH Zurich and Intel co-developed 7 patents for AI-powered semiconductor defect detection.

5. Geopolitical Implications

5.1 U.S. Leadership Under Pressure

The U.S. contributed 34.4% of computer tech patents in 2024, but vulnerabilities loom:

Semiconductor Dependency: 78% of U.S. AI patents rely on Asian-manufactured chips.
Regulatory Pushback: The EU’s proposed AI Act (2025) may restrict facial recognition tools patented by U.S. firms like Clearview AI.

5.2 Europe’s Bid for Sovereignty

The EU’s 29.5% share of computer tech patents masks internal disparities:

Germany: Dominates industrial AI (12.7% growth) but lags in consumer-facing tech.
Switzerland: Emerged as an AI ethics hub, with 23 patents for privacy-preserving ML techniques.

5.3 Asia’s Stalled Momentum

South Korea (-0.1%): Samsung’s 1,097 patents mask stagnation in SMEs due to talent shortages.
China (-6.6%): Huawei’s resilience contrasts with broader declines linked to U.S. chip export bans.
Japan (-7.4%): Shifted focus to quantum computing, where it holds 11.9% of AI patents.

6. Challenges and Ethical Dilemmas

6.1 Patent Eligibility for AI

The EPO rejected 8% of AI patents in 2024, citing:

Lack of Inventive Step: Algorithms deemed “obvious combinations of existing techniques.”
Explainability Gaps: Opaque neural networks (e.g., deep learning models) faced scrutiny.

6.2 Regulatory Risks

EU AI Act: Requires transparency for “high-risk” AI systems, complicating patents for emotion-detection or biometric tools.
Data Privacy: GDPR compliance adds costs for training datasets, disadvantaging European startups.

6.3 Patent Trolling

Non-practicing entities (NPEs) held 6% of AI patents in 2024 (up from 2% in 2020), targeting SMEs with lawsuits. Example: A Milan-based IoT firm paid €300,000 to settle a dubious claim over sensor algorithms.

7. Adjacent Sectors and Future Outlook

7.1 Quantum Computing’s Strategic Role

Though quantum patents dipped slightly (-1.8% to 327 in 2024), key trends emerged:

EPC Leadership (49.8%): Startups like IQM Finland (16 patents) prioritized error correction.
Corporate-Startup Collaboration: IBM partnered with Fraunhofer Society on hybrid quantum-AI systems.

7.2 Green Tech Synergies

The 8.9% growth in electrical machinery/energy patents (e.g., Siemens’ smart grids) highlights AI’s role in sustainability:

Battery Innovations (+24%): AI optimized lithium-ion charging cycles, reducing degradation by 30%.
Wind/Solar AI: Alphabet’s DeepMind cut energy waste in wind farms by 20% using predictive algorithms.

8. Conclusion

The EPO’s 2024 data underscores a pivotal truth: AI and computer technology are no longer siloed fields but the backbone of global innovation. As industries converge and geopolitical rivalries intensify, patents will remain both a weapon and a measure of progress. For Europe, balancing ethical guardrails with competitive agility will determine whether it leads—or follows—in this new era.
