Carl R. Roth

Carl R. Roth is a veteran trial attorney and the founder of The Roth Law Firm in Marshall, Texas, with a practice focused on high-stakes patent infringement litigation. Based on his long history in the Eastern District of Texas, his specialty is representing patent holders in federal court. His work in intellectual property is part of a broader practice that also includes products liability and commercial litigation. Roth is credited with filing the first patent infringement case in the Marshall Division in 1992 on behalf of Texas Instruments, a client for whom he has since handled more than two dozen patent cases, securing judgments and settlements exceeding $2.4 billion.

Consistent with the provided case list, Roth exclusively represents plaintiffs in patent disputes. His appearances for Marshall Feature Recognition, LLC against technology companies like Apple and Barnes & Noble are characteristic of his practice, which involves asserting patent rights for plaintiffs. His firm, The Roth Law Firm, is a "boutique" litigation firm that has developed significant expertise in the local federal courts in the Eastern District of Texas, which is one of the nation's leading venues for patent litigation. Roth serves as the firm's lead litigation counsel and has tried over 300 cases to a verdict over his career.

There is no indication from publicly available information that Mr. Roth has a practice before the Patent Trial and Appeal Board (PTAB) or is regularly involved in IPR proceedings. His focus remains on district court trial work.

Admitted to the Texas bar in 1964, Roth is a graduate of Lamar University (B.A., 1961) and the University of Texas (LL.B., 1964). He is admitted to practice before several federal courts, including the U.S. Court of Appeals for the Federal Circuit.
