Over the span of two decades, the Houston, Texas-based firm Ahmad, Zavitsanos, Anaipakos, Alavi & Mensing P.C., known as AZA, has established itself as a national leader in complex commercial litigation in federal and state courts. The firm's courtroom-savvy lawyers are fierce litigators who have secured a number of landmark verdicts, including Texas' 2011 second-largest verdict in an intellectual property case as well as the second-largest international tort verdict. The same year AZA won one of the largest defense attorneys' fee verdicts in Texas. AZA's seven partners have collectively tried over 200 cases from both sides of the docket, and six attorneys have obtained board certification from the Texas Board of Legal Specialization, five in Civil Trial Law.

AZA's talented team of driven individuals not only possesses degrees from prestigious law schools such as Harvard, Chicago, Michigan, Stanford, Yale and Duke; but it is tough, sharp and courtroom-tested, able to respond intuitively and intelligently both in and out of the courtroom. The firm's prestige has attracted top trial lawyers from larger firms from around the country, and its aggressive, efficient and insightful approach to diverse commercial litigation matters such as oil and gas disputes, patent litigation, and trade secret and convent not to compete cases has cemented its sterling reputation.

AZA has been ranked by corporate counsel among the top firms serving the Fortune 1000 in terms of client service and is in the first tier among U.S. New & World Report's 2013 list of top commercial litigation firms in the nation. Five of the AZA lawyers are recognized among the nation's top lawyers in the 2013 edition of The Best Lawyers in America. Six of the firm's attorneys ranked prominently on the 2013 Texas Rising Stars list, and six have been named on the Texas Super Lawyers list.

Ahmad, Zavitsanos, Anaipakos, Alavi & Mensing is a tough name, but it is an even tougher opponent. The firm has represented high-profile clients such as Air Liquide, Plains All American Pipeline, National Oilwell Varco, and Versata Software Inc., for which it secured a more than $390 million verdict. The firm also mounted a successful defense for a major U.S. pipeline country in a $150 million breach of contract case, and when BTI Consulting Group asked 240 national corporate counsels what U.S. law firms they would never want to go up against in court, AZA made the 2010 list of only 32 firms across the country deemed "Awesome Opponents."

AZA's office is conveniently located in downtown Houston at One Houston Center, recently renamed LydondellBasell Tower. The firm offers services in English, Spanish, Greek, French, Mandarin, Bengali, Russian and Ukrainian.
