Do you believe using AI tools in your work helps you build better professional judgment?

A three-month study published in September 2026 analyzed the performance of 133 patent lawyers at 11 U.S. firms using an AI assistant within Gemini Notebook. Participants utilizing the AI tool demonstrated measurable improvements in drafting scores and speed compared to those working without it.

Why it matters

The findings suggest that integrating generative AI into legal workflows can enhance productivity and output quality. However, the study highlights a performance divergence where senior lawyers maintained gains in unaided judgment while junior lawyers did not.

Lawyers with AI access saw drafting scores improve by 0.34 standard deviations after 10 days and 0.38 by 90 days. Junior lawyers saved 18 minutes on drafting tasks compared to the control group's average of 124 minutes.

The players

Google

Google is a global technology company that funded the experiment costs for the research study.

The details

Participants used a tool integrated into Gemini Notebook to draft simulated patents and perform redlining tasks. While the AI-exposed group scored 0.32 standard deviations higher on unaided tasks, senior lawyers showed a more pronounced improvement of 0.45 standard deviations.

Timeline

  1. 10 days: Lawyers improved drafting scores by 0.34 standard deviations.

  2. 90 days: Lawyers improved drafting scores by 0.38 standard deviations.

  3. September 2026: The working paper was published.

The Tech Race

This research reflects a broader industry shift where large language models are tested against specialized professional benchmarks. It highlights the transition from legacy manual drafting tools to AI-integrated systems in high-stakes fields like patent law.

Legal professionals may see faster document drafting and improved baseline accuracy as firms adopt these integrated tools. Clients could potentially benefit from lower costs or increased speed in the patent application process.

The takeaway

The research demonstrates that AI tools can function as a significant force multiplier for legal drafting tasks. Professionals should monitor how firm-wide adoption of such tools affects the training and skill acquisition of junior staff.
