Kilpatrick Townsend & Stockton

As of May 2026, Kilpatrick Townsend & Stockton LLP is a full-service, BigLaw firm with a major intellectual property practice. Formed by the 2011 merger of Atlanta-based Kilpatrick Stockton and San Francisco's Townsend and Townsend and Crew, the firm has deep roots in both corporate and technology law. Headquartered in Atlanta, Georgia, the firm has over 600 attorneys across more than 20 offices in the U.S., Asia, and Europe. It is consistently ranked among the top 100 U.S. law firms by revenue (AmLaw 100) and is recognized by Vault as a top firm for intellectual property.

The firm's patent litigation practice is extensive, handling disputes across a wide range of technologies. Kilpatrick Townsend's website and industry rankings highlight its work in high-stakes matters involving telecommunications, software, consumer products, life sciences, medical devices, and biotechnology. The firm has litigated over 500 IP cases in federal courts since 2020 and handled over 200 appeals before the Federal Circuit. While the provided case list shows a single recent appearance on the plaintiff side in Corel Software LLC v. United States Patent & Trademark Office, the firm's broader practice description states it represents both plaintiffs and defendants in enforcement and infringement actions.

Kilpatrick Townsend maintains a robust post-grant practice before the Patent Trial and Appeal Board (PTAB). The firm promotes its experience in over 350 PTAB proceedings, representing both petitioners seeking to invalidate patents and patent owners defending them. This dual-sided experience includes inter partes reviews (IPRs), covered business method (CBM) reviews, and other post-grant challenges. The firm has been ranked by third-party services as a top 25 firm by the number of total PTAB trials.

The intellectual property group includes a deep bench of recognized practitioners. While the tracked case data identifies David E. Sipiora as lead counsel, Chambers and other legal directories also recognize partners such as Mehrnaz Boroumand Smith for her patent litigation work with major technology companies. The firm's IP department includes over 250 attorneys, many of whom hold advanced technical degrees, providing broad expertise for complex patent disputes.
