Artificial intelligence (AI) is no longer merely an emerging trend—it has become integral to operational efficiency and strategic innovation in the intellectual property (IP) sector. As patent filings grow increasingly complex and voluminous, European IP institutions and patent law firms are turning to AI technologies to navigate these challenges effectively. This blog post explores how the European Patent Office (EPO), the European Union Intellectual Property Office (EUIPO), and European patent law firms are actively integrating AI solutions, reshaping the way IP professionals work today and in the future.
AI at the European Patent Office: From Search to Strategic Innovation
The EPO has long recognised AI’s potential to streamline its search an examination processes. For instance, the EPO’s EP-AutoCla system utilises advanced machine learning to assign Cooperative Patent Classification (CPC) codes automatically and thus significantly reduces manual classification burden on patent examiners.
Moreover, the EPO’s deployment of sophisticated AI-driven search technologies has set a new benchmark in automated prior art seach. By utilizing semantic similarity algorithms and vector-space searches, the EPO can now more rapidly filter and identify highly relevant prior art documents, providing patent examiners and applicants with more precise and comprehensive search results.
The recent launch of the Legal Information Platform (LIP) further underscores the EPO’s commitment to AI innovation. This generative AI-based legal assistant enables natural language queries across EPO’s legal resources, improving access to crucial patent-related legal information. Similarly, ongoing pilot projects such as AI-assisted minute-taking in oral proceedings indicate a clear strategic direction: AI as an indispensable partner to human expertise rather than its replacement.

AI at EUIPO: Enhancing Trademark and Design Examination
At EUIPO, AI is similarly revolutionising trademark and design examination. EUIPO has integrated AI tools in multiple aspects, including an AI-powered classification assistant, helping applicants quickly identify accurate and standardized goods and services descriptions, minimising procedural rejections.
EUIPO’s AI-driven image recognition systems, now embedded in its popular trademark and design databases TMview and DesignView, allow unprecedented ease in searching for visually similar trademarks and designs. This not only streamlines the process for examiners but also equips applicants and attorneys with powerful tools to proactively manage IP risks.
Moreover, EUIPO has introduced innovative AI-based decision support tools to inform examiners and applicants about potential issues upfront, leveraging historical decisions to anticipate absolute and relative grounds for refusal. This transparency and proactivity improve examination predictability, reducing time-consuming communications between examiners and applicants.
EUIPO’s dedicated AI Roadmap 2025 provides further insights into upcoming enhancements, including automated formality checks, AI chatbots, and AI-assisted decision drafting—initiatives clearly signalling EUIPO’s strategic commitment to digital transformation and efficient, user-centric services.
Unified Patent Court: A Future Aligned with AI
Although currently focused on foundational stability through its digital Case Management System, the Unified Patent Court (UPC) is well-positioned for future AI integration. Given the court’s multilingual context, AI-driven machine translation technologies developed by the EPO and EU institutions are likely candidates for integration into the UPC’s digital infrastructure.
Additionally, as the UPC evolves and generates a growing body of jurisprudence, AI-powered legal research and decision-support tools could significantly enhance judicial consistency and procedural efficiency. UPC’s openness to modernising its processes with digital solutions suggests a readiness to adopt AI technologies once initial operational stability is fully established.
European Patent Law Firms: Early Adopters with Strategic Advantage
Within private practice, European patent law firms are rapidly integrating AI into their workflows to enhance operational efficiency and client service quality. AI-powered semantic search engines, like PatSnap and IPRally, are becoming essential for prior art and freedom-to-operate analyses, allowing attorneys to quickly surface highly relevant references.
Generative AI technologies, as a disruptive force for patent landscape, have shown exceptional promise in patent drafting, significantly reducing drafting and prosecution response times, enabling attorneys to focus on strategic analysis and client advisory roles.
Administrative efficiencies are similarly pursued through AI-powered docketing systems, automated data extraction, and chatbot-driven client intake processes. Although adoption is cautious and mindful of confidentiality and ethical obligations, the trend towards AI-enhanced workflows is accelerating.
Recognizing these trends, professional bodies like the European Patent Institute (epi) have recently issued Guidelines on the Use of Generative AI for patent attorneys, to provide an ethical framework for European patent attorneys using artificial intelligence in the patent profession. The guidelines emphasise the continued importance of professional independence, confidentiality, and client-centred integrity. In particular, they underscore the representative’s duty to exercise personal judgement and not blindly rely on automated systems—a crucial consideration as legal tech solutions proliferate. The important issue of data security and confidentiality is addressed by guidelines 2a and 2b:
Members when using generative AI must, to the extent called for by the circumstances, ensure adequate confidentiality of training datasets, instruction prompts and other content transmitted to AI models. If there is doubt that confidentiality will be maintained to a level that is appropriate to the prevailing context the AI model in question should not be used.
In ensuring adequate confidentiality, Members must inform themselves about the likelihoods and modes of non-confidential disclosures deriving from use of specific AI models.
Conclusion: AI as an Essential Partner in IP’s Future
The widespread adoption of AI technologies by Europe’s leading IP institutions and forward-thinking patent law firms marks a pivotal shift in the IP landscape. Far from replacing the skilled judgement of patent professionals, AI emerges as a powerful ally, augmenting attorney, examiner, and court capabilities to deliver faster, more accurate, and cost-effective IP services.
