For Law Firms, Legal Departments, and Service Providers

AI in Your Practice, Built to Hold Up

Any firm can buy AI tools. The hard part is showing a client, a court, or a malpractice carrier how the work was checked. I help legal teams build AI workflows with measured accuracy, verification that leaves a record, and clear points where a lawyer signs off.

Who This Is For

For Organizations That Answer for Their Work

Law Firms

Partners who want AI in their practice groups and need it to meet the standard they already hold associates to.

Corporate Legal Departments

General counsel and legal operations teams deciding which work to bring in-house, which tools to buy, and how to govern them.

Legal Service Providers

Providers building AI and analytics products for law firms and legal departments, whose output has to survive a lawyer’s review before it ships.

The Method

Four Controls That Make Legal AI Defensible

The four controls come from my own research, where a wrong answer ends up in print under my name. In the DuPont work, I checked the model’s coding against my own hand review of 1,002 factor-level findings; they agreed 97.11% of the time (one reviewer, not blind to the model’s coding).

  1. Structure the Inputs

    The model works from a closed set of sources you control: the record, the file, the governing authority. Everything it says has to trace back to something in that set.

  2. Measure Before Trusting

    Before a workflow goes live, it is tested against work your own lawyers have already done, and its accuracy is recorded. That number decides where the workflow can be used.

  3. Verify With a Record

    Every citation and factual claim is checked against its source, and the check is logged: what was checked, how, and with what result.

  4. Assign a Lawyer to Sign Off

    Each output has a named lawyer who reviews it and owns it. The depth of that review is set by the risk of the task.

Engagements

Ways to Work Together

The usual starting point is an assessment; the other engagements build on what it finds. Each one is scoped in writing before it begins, and the written engagement agreement sets whether the work includes legal advice.

Built From the Research

Alongside advisory work, MarkSense Analytics, the company I founded, offers a scoring platform built from the data behind my research. It measures the similarity of trademarks and scores likelihood of confusion against the record of decided cases. Scores describe how comparable decided cases came out; they do not predict how any particular matter will be decided.

The same method can be applied to other multifactor tests, such as fair use and patent obviousness.

Background

Why Organizations Bring Me In

Research Tested in Public

My AI-driven study of about 4,000 trademark decisions, Doctrine, Data, and the Death of DuPont (opens in new tab), appears at 36 Fordham Intell. Prop. Media & Ent. L.J. 678 (2026). MLex, World Trademark Review, and The Fashion Law covered it, and the cert petition in World Champ Tech v. Peloton, No. 25-736, cited it. I am also the sole author of an amicus brief in RiseandShine Corp. v. PepsiCo, Inc., No. 24-1016, filed July 20, 2026, after the Supreme Court granted certiorari.

Practice Experience

I practiced IP law at Kutak Rock (2018 to 2022) and as a patent attorney at Bookoff McAndrews (2023 to 2024), advising clients from startups to Fortune 5 companies.

A Grounded Tool, Measured

I built The Fair Use Database (opens in new tab), which codes every substantive federal fair use opinion. Its research assistant, Folsom, answers only from the coded corpus and cites its evidence, and its outcome coding agrees with 453 human-coded analyses 97.4% of the time.
