Amos L Mazzant

An accomplished jurist with extensive experience in federal court, Judge Amos L. Mazzant III is the Chief United States District Judge for the Eastern District of Texas. Nominated by President Barack Obama, he was confirmed by the Senate in December 2014. Prior to his appointment as a district judge, he served as a U.S. Magistrate Judge in the same district from 2009 to 2014. His earlier career includes service as a justice on the Texas Fifth District Court of Appeals, time in private practice, and numerous years as a law clerk for three different federal judges in the Eastern District of Texas.

Judge Mazzant presides over a substantial patent docket and is regarded as being well-versed in complex patent litigation. Analytics from Lex Machina consistently place him among the more active patent judges in the United States. Within the Eastern District of Texas, a perennially popular venue for patent cases, his patent caseload is second only to that of Judge Rodney Gilstrap. The court follows a detailed set of local patent rules that govern the timing of infringement and invalidity contentions, claim construction proceedings (Markman hearings), and other case management deadlines. Judge Mazzant typically manages his patent cases under these district-wide rules and does not have judge-specific standing orders for patent matters.

A notable recent development on Judge Mazzant's docket is his assignment to the multidistrict litigation (MDL) In re: Rare Breed Triggers Patent Litigation (MDL No. 3176), which involves numerous patents related to forced reset triggers for firearms. The Judicial Panel on Multidistrict Litigation selected him for this assignment, which is his first MDL, citing his experience with complex patent cases. In another significant patent matter, Judge Mazzant was one of the first judges to award treble damages for willful infringement under the U.S. Supreme Court's standard set in Halo Electronics, Inc. v. Pulse Electronics, Inc., enhancing a $7 million jury verdict to $21 million against Samsung.

In managing his cases, Judge Mazzant has emphasized that discovery should not be constrained by unresolved pleading challenges. In one patent case, he ordered a defendant to produce discovery despite its argument that the plaintiff had failed to adequately plead compliance with the patent marking statute, reasoning that a party cannot use an alleged pleading deficiency to limit the scope of discovery before obtaining a dispositive ruling on the issue. This approach underscores a focus on moving cases forward through the discovery process in accordance with the Federal Rules of Civil Procedure.
