Peter J. Armenio, Co-Chair of Cahill’s Intellectual Property Litigation and Life Sciences Patent Litigation practices, focuses his practice on intellectual property matters, including pharmaceutical, biotechnology, and medical device patent litigation and counseling.

Peter has represented clients at the forefront of these areas for three decades, including in their most important “bet the company” matters. Peter has also handled a wide range of other patent and related commercial matters in courts across the country and in national and international arbitrations. He has represented clients from three continents – North America, Europe, and Asia – ranging from the Fortune 100 to start-ups.

Peter has been recognized by Chambers USA as a leading lawyer in intellectual property every year since 2007, and has been similarly recognized by Chambers Global every year since 2013. Chambers has noted in various years that Peter is "a fantastic trial lawyer," "one of the brightest ANDA litigators out there today," "tremendously strategic in setting up a case," and has a "track record of winning."

Peter has been listed in a number of other guides and rankings, including IAM Global Leaders 2023, Managing Intellectual Property magazine's "America's Best Life Sciences Litigators," the IAM Life Sciences 250, IAM Patent Litigation 250, and IAM Patent 1000.
