Dunstan H. Barnes is a Partner at McAndrews and practices in all areas of intellectual property law with emphasis on protecting and analyzing design rights.

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  U.S. and 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.”
