Best Law Firms in Texas for Litigation - Intellectual Property

Ahmad, Zavitsanos & Mensing, or AZA, is first and foremost a trial firm. Its more than 60 lawyers bring clients a formidable courtroom record in complex commercial litigation, including energy, trade secret, intellectual property, construction and real estate, environmental, class action, restrictive covenant, catastrophic injury, and business dispute cases. The firm's partners have tried more than 250 cases, and AZA has been in trial nearly every month since 2016.

AZA has earned a coveted rating for its Texas commercial litigation work in every edition of Chambers USA: America's Leading Lawyers for Business from 2014 through 2026. U.S. News & World Report and Best Lawyers have named AZA a Tier 1 firm in Commercial Litigation and Appellate in their Best Law Firms rankings, and Best Lawyers in America lists 14 AZA lawyers in Houston Commercial Litigation, more than any other firm. Benchmark Litigation, the definitive guide to America's leading litigation firms and attorneys, has recognized all three of AZA's name partners. Lawdragon has named 11 AZA lawyers to its 500 Leading Litigators in America, and more than half of the firm's attorneys were selected to the 2026 Texas Super Lawyers or Rising Stars lists.

Those rankings rest on results. AZA has secured one of the nation's top 50 plaintiff verdicts ten years running, obtained one of the top 10 IP verdicts in the country in 2025, and won the largest Harris County jury verdict in commercial litigation in 2024. Law360 named AZA a 2026 Regional Powerhouse, one of only five firms in Texas to earn the distinction, and Firm Prospects ranks AZA among the top 25 boutiques in the nation. Texas Lawyer has named AZA Litigation Department of the Year four times and inducted the firm into its Texas Verdicts Hall of Fame. And AZA is among the nation's "Most Feared" law firms, as identified by general counsel and in-house litigators surveyed by BTI Consulting.

Dedication to clients, coupled with the ability to prevail before judges and juries alike, is why general counsel across the country know AZA. Clients including Chevron, LyondellBasell, Halliburton, KBR, TotalEnergies, Transocean, and the Houston Rockets trust the firm with their most difficult matters, and AZA is often hired on the eve of trial, once it has become clear a case must be tried. It is also why corporate counsel have named AZA one of the firms with the best client service among those serving the Fortune 1000. In fact, AZA has been hired many times by the same companies it has beaten at trial.

Founded in 1990 by noted trial lawyer Mark Lanier, The Lanier Law Firm is recognized as one of the premier trial law firms in the United States. The firm’s experienced trial attorneys represent companies and individuals across the country from offices in Houston, New York, Los Angeles and Dallas/Fort Worth.

The firm’s vast trial experience includes substantial verdicts in cases involving asbestos exposure and mesothelioma, serious personal injuries, product liability, dangerous drugs, business fraud, and other civil litigation. The firm also is noted for its work defending some of the country’s largest companies. For example, in 2016, Mr. Lanier won two federal trial jury verdicts that together totaled more than $1.5 billion in litigation over metal-on-metal hip implants manufactured by DePuy Orthopaedics Inc., a subsidiary of New Brunswick, New Jersey-based Johnson & Johnson. In April 2014, Mr. Lanier and the firm won a record verdict against pharmaceutical giants Takeda Pharmaceutical Co. Ltd. and Eli Lilly & Co. over the dangerous side effects of the diabetes medication Actos, which ranked as the 7th largest verdict in U.S. history. More recently, Mr. Lanier secured a historic $4.69 billion verdict against Johnson & Johnson in the first trial verdict to affirm the link between asbestos-laden talcum powder and ovarian cancer.

Although record-setting legal victories are a firm trademark, the primary focus remains with Mr. Lanier’s original vision to provide “the highest quality legal care delivered in an honest, professional manner to enrich the lives or businesses of our clients.” Every attorney at The Lanier Law Firm is committed to solving clients’ problems while working toward favorable legal resolutions.

Mr. Lanier serves as the firm's lead litigation counsel and is recognized as one of the nation’s top trial lawyers.

The National Law Journal has recognized Mr. Lanier as one of the nation's Top 10 Trial Attorneys on two different occasions and highlighted him as one of the "100 Most Influential Lawyers in America" and one of the "Decade's Most Influential Lawyers." Following his victory in the nation’s first trial over the pain medication Vioxx, Mr. Lanier was described in The New York Times as “one of the top civil trial lawyers in America.”

Chambers USA and The Legal 500 ranked The Lanier Law Firm among the nation's leading firms for work in Plaintiffs' Product Liability and Mass Tort Class Actions. Editors of The National Law Journal named The Lanier Law Firm among its list of Elite Trial Lawyers and as the nation's top-ranked law firm in the area of Medical Device Litigation.

A strong supporter of his alma mater, Mr. Lanier earned his law degree from Texas Tech University School of Law in 1984. He remains active at Texas Tech by serving on the Law School's Foundation Board and was previously honored as the Texas Tech University School of Law Distinguished Alumnus.

Another hallmark of The Lanier Law Firm is its dedication to professional and community involvement.
