Episode description:
John Quinn is joined by Caleb Harris, Co-Founder and CEO of &AI, a startup focused on using artificial intelligence to transform patent litigation. They discuss how &AI uses AI to accomplish complex patent litigation tasks such as invalidity and infringement analysis, dramatically reducing the time and cost associated with these traditionally labor-intensive efforts. The service features four components: searches for prior art or infringing products, in-depth legal analysis (including creating claim charts), drafting litigation-ready documents like invalidity contentions or IPR petitions, and automating workflows using AI agents that operate independently.
Patent litigation is particularly well-suited to AI because so much of the underlying data—such as patent filings, litigation histories, and prosecution records—is publicly available. &AI continuously updates its data sets and can provide summaries, detailed claim charts, and customized drafts in as little as 10 minutes. Unlike generative AI tools, &AI minimizes hallucinations by relying heavily on document retrieval rather than generation, and by providing verified citations in its output.
The platform can also help streamline early-stage litigation decisions, such as assessing the strength of a patent portfolio or evaluating potential infringement claims in the marketplace. It also helps defense teams efficiently assess and respond to weak claims, including those from patent trolls, by producing tailored response letters and evidence.
&AI uses AI agents—AI that develops multi-step plans to accomplish tasks and automatically adjusts those plans based on how the work is progressing. This allows the user to focus on the end product they want rather than the steps needed to get there. AI agents will enable faster, more scalable, and more economically viable litigation, especially patent litigation. This may lead to a boon for litigators as more lawsuits are filed and resolved quickly. Although human performance will remain crucial in areas like persuading a jury or a judge, law firms may gain a competitive edge by pairing their expertise with firm-specific AI tools trained on the firm’s proprietary data and preferred styles.
