Siebman Forrest Burgess & Smith

Siebman, Forrest, Burg & Smith, LLP is a Texas-based, trial-focused law firm established in 1991, primarily serving clients in the U.S. District Courts for the Eastern and Northern Districts of Texas and across the state. With offices in Marshall and Lufkin, Texas, the firm is known for its regional presence and often collaborates with national trial teams for major corporations, providing local Texas counsel or serving as lead trial counsel on complex litigation matters. While the firm is not categorized as BigLaw or a pure IP boutique, its attorneys, particularly in intellectual property, have received individual recognition in legal rankings.

The firm specializes in intellectual property litigation, including patent, copyright, and trademark law, alongside broader commercial and product liability litigation. Based on tracked appearances, the firm has represented defendants in patent matters, often taking on roles as local counsel. Its experience includes cases involving mechanical components, as demonstrated by its representation of ProSource Firearms LLC as local counsel in Rare Breed Triggers Inc et al. v. ProSource Firearms LLC.

In the tracked case, Rare Breed Triggers Inc et al. v. ProSource Firearms LLC, the firm acted as local counsel for the defendant. This case is related to broader, high-profile litigation concerning "forced-reset triggers" (FRTs) for firearms. While specific outcomes for ProSource Firearms LLC are not publicly detailed, the overall legal landscape for Rare Breed Triggers' products saw significant developments, including a May 2025 settlement between Rare Breed Triggers and the Department of Justice. This settlement allowed Rare Breed to continue lawful operations, following a June 2024 Supreme Court ruling that found bump stocks could not be classified as machine guns, a decision subsequently applied to FRTs by a federal court in the Northern District of Texas in July 2024. More recently, in February 2026, a federal judge denied Rare Breed's request for a preliminary injunction against another company for alleged patent infringement related to similar trigger devices.

The firm's patent litigation practice does not have a publicly documented emphasis on Patent Trial and Appeal Board (PTAB) or Inter Partes Review (IPR) proceedings.

Key partners include Clyde M. Siebman, a co-founder and a recognized leader in the East Texas intellectual property bar, with consistent recognition in Texas Super Lawyers and The Best Lawyers in America for patent litigation, among other areas. Michael C. Smith leads the firm's Marshall office and is a prominent patent litigation attorney. He has served as counsel of record in over 800 civil cases in the U.S. District Court for the Eastern District of Texas and has been selected as a Texas Super Lawyer for intellectual property litigation since 2008.
