Dunstan H. Barnes is a Partner at McAndrews and practices in all areas of intellectual property law with an emphasis on protecting and analyzing design rights. His work in that area includes drafting and prosecuting design patent applications and conducting opinion work and due diligence investigations. In addition, Dunstan has considerable experience drafting and prosecuting utility patent applications and trademark applications across a range of technological fields and industries.
As a practitioner, Dunstan is an effective communicator and an outstanding writer. He is particularly skilled at communicating complex, abstract technical concepts clearly and compellingly. He is a skilled intellectual property advocate and adviser who helps his clients protect their innovations, particularly new designs, in the U.S. and in global marketplaces. He helps his clients acquire and protect their IP rights, as well as navigate the world of existing rights. In 2021, Dunstan was honored as a 40 Under Forty attorney in Illinois. In recommending him for the honor, a senior IP counsel at a major international pharmaceutical company said of Dunstan, “I consider him to be one of the top 10 design patent attorneys in the United States, period.”
Dunstan is the current Chair of the American Bar Association (ABA) Design Rights Committee and Vice Chair of the American Intellectual Property Law Association (AIPLA) Industrial Designs Committee. He has been an invited speaker at conferences including AIPPI World Congress, AIPLA Annual Meeting, ABA-IPL Spring Meeting, and USPTO Design Day.
In his spare time, Dunstan enjoys football (soccer) in pretty much any weather, bass guitar, poker, and keeping up with his ever-energetic young daughter.
