Patent Litigation

AZA’s IP group is known for its unique ability to take on its clients’ most complex patent infringement disputes. We excel at explaining highly technical concepts to judges and juries around the country—no matter the industry or technology. Because of that, publications like Chambers USA and IAM Patent 100 have consistently ranked AZA as a top intellectual property litigation firm.

Chambers USA describes AZA as a “respected Houston-based litigation boutique with notable expertise advising clients involved in high-stakes IP disputes,” and a firm with “particular expertise handling complex patent infringement litigation, including at trial, for clients from a wide range of industries.” IAM Patent 100 also writes: “AZA is perfectly in step with its clients’ objectives, works relentlessly to achieve them, and has a superb track record of trial wins to show for it.”

We have the technical know-how and courtroom experience not just to take the most complex intellectual property case to trial, but to win it when we do.
