Awards & Recognition

Selected for inclusion in Minnesota Rising Stars, 2010, 2012-2015

While working as a chemist, Aaron discovered the fascinating world of patents, specifically the intellectual challenge of acquiring patent rights and designing around currently-existing patent rights. Intellectual property law was a natural career path, particularly litigation, where he enjoys both developing strategies for trial and addressing unanticipated problems as they arise.

Aaron's practice focuses on intellectual property litigation with an emphasis on patent infringement actions, as well as copyright, trademark, trade secret, rights of publicity, and unfair competition. He is experienced in all stages of litigation, including Markman hearings, depositions, pretrial investigation, discovery, pre- and post-trial motions, appellate work, and most importantly, trial—including serving as second chair in a two-week patent infringement jury trial. Aaron has also participated in several commercial litigation matters beyond those implicating intellectual property rights, as well as AAA and FINRA arbitrations.

Aaron represents clients across a broad spectrum of technological areas, including pharmaceuticals, medical devices, construction materials, safety and security technologies, business methods, pet care products, and telecommunications.

His masters degree in chemistry and technical background in synthetic organic chemistry greatly assist him in counseling clients in the pharmaceutical and biotechnology industries, and in particular, those involved in ANDA litigation. He speaks the technical language well and is good at translating it into simpler terms for judges and juries.

Prior to his legal career, Aaron's professional interests concentrated on the synthesis and characterization of large natural products and related analogs with pharmaceutical activity, in both academic and industrial settings. While attending law school, he clerked with the IP department of a Fortune 500 corporation's pharmaceutical division.

Aaron's pro bono activity includes working with the Hennepin County Housing Court Project in Minneapolis, as well as appealing the administrative denial of disability benefits in Social Security cases. He serves on the library resources committee at Merchant & Gould.

Aaron has three children and enjoys film, literature, and major league baseball.
