EPO to Use AI Tools for Minuting Oral Proceedings

The European Patent Office (EPO) has announced a pilot project to implement artificial intelligence tools to assist in the preparation of minutes during oral proceedings conducted by videoconference. This development represents a notable evolution in the EPO's approach to procedural documentation, but aligns with the recent trend of increasing AI adoption by the EPO generally.

EPO to Use AI Tools for Minuting Oral Proceedings

Background: Manually-Recorded Minutes

The EPO has consistently maintained that oral proceedings are not to be recorded, by the EPO, parties to proceedings, or the public, with the minutes prepared by the responsible EPO division serving as the only official record. The 2025 Guidelines for Examination (E-III, 10.1) specify that "Sound recordings are made only in the case of taking of evidence. The recording is kept until the end of any possible proceedings. Copies of the recording will not be provided to the parties." This limited exception has been the only context in which any form of recording was permitted during EPO proceedings.

The New AI Initiative

In an announcement dated April 8, 2025, the EPO stated it will begin using AI to assist in preparing minutes for oral proceedings conducted by videoconference. The EPO has provided some clarity regarding how use of an AI tool to this end will be implemented:

  • Oral proceedings held by videoconference before the Receiving Section, examining divisions, opposition divisions and the Legal Division may be audio recorded by the EPO
  • The pilot will initially be limited to proceedings conducted in English.
  • These recordings will be deleted once the minutes of oral proceedings are issued to the parties to proceedings.
  • This will apply from 1 May 2025 
  • The recording or transmittal of oral proceedings in any form by participants other than EPO employees remains prohibited.

Implications for Patent Practitioners

This development reflects the EPO’s growing recognition that carefully implemented and appropriately supervised AI tools may help to enhance procedural efficiency without compromising legal certainty.

For patent attorneys regularly appearing before the EPO, this pilot also raises interesting questions about the future role of AI in proceedings. Although recording proceedings by other participants is still expressly prohibited, if the EPO itself is now utilizing AI tools during oral proceedings, might similar technologies eventually be permitted for use by participating parties?

At Solve Intelligence, we are closely monitoring these developments and the wave of AI adoption across patent offices around the world more generally. The EPO themselves have stated that "The EPO is committed to using AI and machine learning technologies to increase quality and efficiency in the patent grant process [...] closely following a human-centric approach." We share this human-centric philosophy at Solve Intelligence, where we believe in putting patent attorneys in the driving seat of AI adoption. Our approach focuses on augmenting—not replacing—attorney expertise, ensuring that human judgment remains central while leveraging AI to handle routine tasks and improve efficiency. We recognize that the most effective AI solutions for patent practice are those that complement attorneys' specialized knowledge while giving them complete control over the final work product.

The Hidden Cost of Ignoring AI in Patent Practice

As patent practitioners, the choice to “do nothing” about AI is not a neutral act. 

Law firms or in-house counsel that delay the adoption of AI may believe they are minimizing risk, but oftentimes they are taking on a different set of less visible, long-term risks. 

These hidden costs can accumulate quickly, from compounding inefficiencies in traditional patent drafting workflows to missed revenue opportunities that remain untapped without leveraging AI-driven capabilities.

So, what can patent practitioners do to stay ahead of the game? Here is what the Solve Intelligence team has seen speaking with thousands of practitioners.

Key takeaways

  • Waiting to adopt AI is itself a strategic decision with compounding costs.
  • Manual patent workflows create time, quality, and knowledge bottlenecks that grow over time.
  • Firms already experimenting with AI gain operational insight that late adopters cannot shortcut.
  • Low-risk entry points let practitioners build confidence without compromising legal judgment.

Why Patent Attorneys Need Purpose-Built AI

Legal AI platforms like Harvey and Legora are valuable productivity tools. Powered by large language models and enriched with legal data sources, firm-specific knowledge, and purpose-built workflows, they perform well on tasks like legal research, document summarisation, and contract or email drafting.

But their workflows are optimised for breadth across practice areas, not for the structural, technical, and jurisdictional depth that patent work requires.

For IP teams that already have access to a generalist platform, or are trying one out, the natural follow-up question is whether a vertical solution adds enough to justify the investment. 

At Solve Intelligence, we build AI specifically for patent practitioners. In our experience scaling the platform to over 500 IP teams, there is no question that patent-specific tooling delivers ROI that generalist platforms alone cannot. This article sets out why.

Key takeaways

  • Generalist legal AI tools weren't trained for the structural depth patent work demands.
  • Solve Intelligence is shaped by in-house patent attorneys who joined Solve from firms like Carpmaels & Ransford and Fish & Richardson.
  • Custom templating lets attorneys match output to house style, client/technology area, or jurisdiction.
  • Generalist and patent-specific AI are complementary investments, not competing ones.

Marbury Law sees 3x-4x efficiency gain from using Solve Intelligence

When we sat down with Bob Hansen for this conversation, we knew it would be grounded in both legal depth and real-world business experience. Bob is a founding partner of The Marbury Law Group and has extensive experience across patent prosecution, litigation, licensing, portfolio strategy, and complex IP transactions. But what makes his perspective particularly compelling is that he also brings 20 years of real-world experience as an engineer, program manager, and business executive in Fortune 50 companies and start-ups. He understands firsthand how innovation moves from idea to product, and how intellectual property law fits into that journey.

That dual lens is exactly why we wanted to have this discussion. Bob evaluates technology not just as a patent attorney, but as someone who has managed engineering teams, navigated acquisitions and divestitures, raised capital, and built businesses. When someone with that background says AI has been transformative and backs it up with measurable 3 to 4x efficiency gains, it’s worth listening.

Key Insights

  • AI adoption requires proof. Bob and his team tested multiple tools before committing, and only moved forward once they saw quantifiable results.
  • 3 to 4x efficiency gains changed the business case. By tracking his own drafting time, Bob demonstrated that AI-enabled workflows made fixed-fee work viable at partner rates.
  • Demonstration drives adoption. Live drafting sessions, client transparency, and side-by-side cost comparisons created full buy-in from both clients and colleagues.
  • Integrated chat removes friction. Keeping research, drafting, and revisions inside one contextual workspace eliminated copy-paste workflows and saved significant time.
  • Context is a force multiplier. AI performs best when it understands the full invention disclosure, file history, and drafting materials in one place.
  • Speed expands strategic value. Faster drafting didn’t just save time - it enabled better coverage, stronger enablement, and real-time responsiveness to client needs.

Introducing Solve Review: A Practical Guide to AI-Powered Patent Review

Patent drafting doesn’t end when the first draft is complete. In many ways, the most important work begins at review.

Jurisdictional compliance, internal style alignment, claim clarity, sufficiency of disclosure, and formal requirements. Each aspect of drafting applications must be carefully checked before filing. Yet a thorough review is time-intensive, difficult to standardize, and hard to scale across teams and large portfolios, especially when up against a tight deadline.
