In high-stakes professional work, the bar for AI isn't just speed, it's trust. Professionals aren't asking whether AI can generate an answer; they're asking whether they can stand behind it. That starts with a system built on authoritative content, expert judgment, clear provenance, and strong boundaries around customer data. That's the standard we're building to. 🔗ow.ly/nmIw50YKFFM

General-purpose AI is powerful. But in legal work, almost right is not good enough. Watch how Thomson Reuters and Anthropic are connecting Claude to CoCounsel Legal through a new MCP integration, combining frontier AI with trusted legal workflows built for professionals. ⬇️

A sincere thank you to our incredible partners at @thomsonreuters and @TRSSLLC for being the exclusive sponsor of this year’s Champions for Children event, which honors the law enforcement professionals who work every day to protect children. We were also grateful to welcome their team to NCMEC headquarters for a visit and to see them roll up their sleeves to pack HOPE Bags for survivors of child sex trafficking. We deeply value this long-standing partnership and our shared commitment to helping ensure every child has the safe childhood they deserve.

Join the Thomson Reuters Institute (TRI) and the National Center for State Courts (NCSC) for the next webinar in the TRI/NCSC AI Policy Consortium series, "Agentic AI in Legal Settings: Guardrails for Responsible Innovation." This session explores the next evolution of AI technology: Agentic AI systems that can independently plan and execute multi-step tasks with limited human oversight. Our expert panel will help you understand the critical distinctions between standard AI and Agentic AI, identify unique risks in legal settings, and apply tiered risk frameworks that protect accountability while embracing innovation in courts and legal practices. 📅 May 20, 2026 ⌚ 1 p.m. ET ➡️ Link to register: ow.ly/ixEE50Z0b6s

Thomson Reuters is partnering with our customer Sterne Kessler Goldstein & Fox to set a new standard for how legal AI gets built.   Section 101 patent eligibility is one of the most consequential and frustrating challenges in patent practice: precedent-heavy, inconsistently applied, and often the fastest way to win or lose a case. Yet for most practitioners, the analysis still means hours of research, with no guarantee something important wasn't missed.   We built something different. Our engineers worked side by side with Sterne Kessler's IP litigators, co-building in rapid iterations, to develop the Patent Claim Eligibility Analyzer inside CoCounsel Legal, which delivers a market‑ready starting point for patent eligibility analysis.  It is purpose-built for the specific, high-stakes reality of patent practice, grounded in a curated corpus of Federal Circuit decisions, and verified through Westlaw.   This is what becomes possible when practitioners and technologists build together, and it's just the beginning.   Emily Colbert, Thomson Reuters, and Dan Block, Sterne Kessler Goldstein & Fox explain how we did it.

One million professionals across 107 countries and territories use CoCounsel. Today is one step in making fiduciary-grade AI available across the full ecosystem of tools and environments lawyers work in every day. ow.ly/51eF50YYm95 #CoCounsel #LegalTech #LegalProfessionals

As our Chief Technology Officer, Joel Hron, put it: "In professional environments, trust in AI is a property of the system itself, built into the architecture and verifiable at every step." This summer, we go further. The next generation of CoCounsel Legal, rebuilt on Anthropic's Claude Agent SDK and already in beta for customers in the United States, evolves to plan, select tools, retrieve authoritative content, and adapt mid-workflow. Lawyers will describe a matter in plain language and have CoCounsel Legal pursue the right inquiry, draft with citations, and deliver fiduciary-grade work product.

General-purpose AI is powerful. But in legal work, almost right is not good enough. Today, Thomson Reuters and Anthropic are expanding its partnership, connecting Claude directly to CoCounsel Legal through a new MCP integration.

Why does this matter? Every legal output has to hold up in a filed brief, a closed transaction, or a regulatory position. CoCounsel Legal is built to meet that standard, reasoning across: ✨1.9 billion Westlaw and Practical Law documents ✨1.4 billion KeyCite validity signals ✨A patent-pending citation ledger, traceable in one click

Legal professionals can now move seamlessly between general-purpose AI and citation-grounded legal work. No platform switching. No re-entering context. No sacrificing the rigor their professional obligations require.

For legal, tax, audit, accounting, and compliance professionals, the promise of AI is not just productivity. It is confidence in the work they are accountable for. Watch Steve's full conversation below. 📷 youtube.com/watch?v=GgHiKL…

AI agents become more capable, trust becomes the true differentiator. In a discussion from the AI Agent Conference, Thomson Reuters CEO Steve Hasker shared why high-stakes professions need more than general-purpose AI. They need fiduciary-grade AI: built on authoritative content, shaped by expert insight, protected by rigorous safeguards, and designed to deliver transparent, verifiable outputs.

If you had a $1,000,000 case on the line, would you trust the same tool people use to plan vacations and write birthday cards? Your clients deserve AI built for the work you actually do. CoCounsel Legal is grounded in Westlaw and Practical Law content, and your data is never used to train the model. See why the most trusted firms are making the switch: ow.ly/OLkJ50YXLIF #CoCounsel

AI is reshaping the legal industry. But access to new tools is only the first step.   For law firms, the real challenge is turning AI adoption into sustainable habits that stick.   Womble Bond Dickinson shows what that looks like in practice. Rather than rolling out technology in isolation, the firm embedded CoCounsel Legal across all seven staffed UK offices by focusing on culture, leadership, and true partnership.   Chief Innovation Officer Sam Dixon led the charge, moving beyond standard training to create direct engagement that helped lawyers see the platform's real-time value.   A key part of this success was Thomson Reuters' co-development partnership with the firm. Through ongoing collaboration and honest feedback, both teams stress-tested and refined CoCounsel Legal to address the practical challenges lawyers face.   The result?   Up to 80% efficiency gains on specific tasks — and a culture where AI has become a natural part of legal work.   Womble Bond Dickinson's approach shows how firms can move from AI access to AI integration, turning technology into a professional advantage.   Read more here: ow.ly/Hg6B50YWa30 #CoCounsel #LegalAI

Only CoCounsel Legal can access the legal authority and know-how of Westlaw and Practical Law at every step. It doesn’t just think like a lawyer. It works like one.

Attorneys at Troutman Pepper Locke LLP no longer have to think about which AI tool to use because the answer is automatically available, right where they work.

Attorneys have been sanctioned for citing cases that do not exist, quoting passages that were never written, and submitting work that they did not verify, even though their names were on the documents.   This is the legal AI problem that nobody wants to talk about. The tools were fast, and the outputs looked professional, but the verification step was either skipped or made too difficult to complete.   Professional accountability does not transfer to the tool; it remains with the lawyer. That means AI must be built to make verification straightforward at every stage by providing traceable sources, real-time citation checking, and work product that a professional can stand behind before it leaves their desk.   That is the standard CoCounsel Legal was built to meet.
