For more than 15 years, Matthew C. Nielsen delivered winning results to clients such as Amgen, Cabela’s, Eli Lilly, Illumina, Merck-Serono, and RR Donnelley. He accomplished this in jury and bench trials, and in appeals to the Federal Circuit. Mr. Nielsen’s success came from his earlier practice prosecuting patent applications, his knack for developing winning themes and arguments, and his ability to take complex legal and technical issues and explain them in a way that is easily understood. Mr. Nielsen provided strategic counseling to both mature and emerging clients on protecting their intellectual property and navigating the IP rights of others. In 2013, Mr. Nielsen was selected for inclusion in the Illinois Rising Stars® list, featuring outstanding young attorneys in the State of Illinois.
