Awards & Recognition

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

Aaron’s practice focuses on intellectual property matters with an emphasis on patent infringement and other matters concerning technology.  His chemical and pharmaceutical background provides him with real-world industrial perspective when working with clients.  Aaron particularly enjoys managing the acquisition, enforcement, and protection of intellectual property rights, including patents, trademarks, trade secrets and copyrights. He has counseled clients on a variety of IP matters, including licensing, due diligence, and portfolio strategy. He is registered to practice before the USPTO and has experience in patent prosecution. 

Aaron 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. Aaron also participated in several commercial litigation lawsuits and arbitration proceedings. 

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

His advanced degree and technical background in synthetic organic chemistry greatly aids him in counseling clients in the pharmaceutical and biotechnology industries, and in particular, those involved in ANDA or Hatch-Waxman litigation.

Prior to his legal career, Aaron’s professional interests concentrated on the synthesis and characterization of complex 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 and appealing the administrative denial of disability benefits in Social Security cases.

Outside of the office, Aaron enjoys spending time with his wife and three children and is an avid fan of baseball and film.
