Daignault Iyer LLP: Professional Summary

Date: 2026-05-09

Prepared By: Senior Patent Litigation Analyst

Daignault Iyer LLP is an intellectual property litigation boutique with its office in Vienna, Virginia. The firm describes its practice as focused on complex and high-stakes IP litigation. While specific AmLaw, Vault, or Chambers rankings for the firm are not available in public sources, which is common for specialized boutiques, its partners have backgrounds that include experience at larger law firms. The firm's key partners are Ronald M. Daignault and Chandran B. Iyer.

The firm’s primary focus is on patent monetization for patent owners and Hatch-Waxman litigation on behalf of generic drug companies. This is consistent with the firm's representation history in its tracked cases, which is exclusively on the plaintiff side. Attorneys at the firm have technical backgrounds across a range of areas, including electrical engineering, computer science, software, networking, semiconductors, and various life sciences fields like biomedical and chemical engineering. The tracked cases involving AlmondNet and Aml Ip LLC suggest experience in software and internet-related technologies.

Daignault Iyer's litigation practice is plaintiff-oriented, concentrating on representing patent owners. In the tracked matters, the firm has acted exclusively for plaintiffs. In AlmondNet, Inc. v. Yahoo! Inc., a case involving internet advertising technology, partner Chandran B. Iyer served as lead counsel for the plaintiff. In Aml Ip LLC v. Chipotle Mexican Grill, Inc., partner Ronald M. Daignault was of counsel for the plaintiff, which asserted a patent related to business methods or processes. Publicly available information on significant verdicts or settlements for these specific representations is limited. However, the firm's website notes it has secured hundreds of millions of dollars in favorable settlements and court awards for patent owners generally.

The firm states that it handles inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB), in addition to its work in U.S. district courts and the International Trade Commission (ITC). However, a reliable public record of its PTAB filing frequency is not readily available. The practice is led by seasoned litigators, including Ronald M. Daignault, who has nearly three decades of experience in IP litigation and has argued before the U.S. Court of Appeals for the Federal Circuit, and Chandran B. Iyer, who has over twenty years of experience focused on helping patent owners monetize their IP through litigation and licensing.
