Dunstan H. Barnes, Ph.D.


Dunstan H. Barnes practices in all areas of intellectual property law, with a special focus on protecting and analyzing design rights, which includes drafting and prosecuting design patent applications, and conducting opinion work and due diligence investigations. Dunstan has considerable experience drafting and prosecuting utility patent applications and trademark applications in a range of technological fields and industries.

Dunstan graduated from Chicago-Kent College of Law, where he was the President of the Intellectual Property Law Society, a Notes & Comments Editor for the Chicago-Kent Law Review, a Submissions Editor for the Journal of Intellectual Property, and a Co-Captain of the “Chicago-Kent Sportfeasors” soccer team. In addition, he competed in the 2013 American Bar Association’s National Appellate Advocacy Competition as a member of Chicago-Kent’s Moot Court Honor Society. During law school, Dunstan received awards for achieving the highest grade in his Legal Writing and Trademarks & Unfair Competition courses. In 2013, Dunstan was inducted into both the Bar & Gavel Society and the Order of the Coif.

Prior to law school, Dunstan earned his Ph.D. in Materials Science & Metallurgy from the University of Cambridge. His doctoral research explored the development and enhancement of biomimetic calcium phosphate coatings applied to the endplate surfaces of artificial polymeric spinal disc devices. During his doctorate, Dunstan presented his research at five international conferences in the Netherlands, South Korea, United Kingdom, and United States (twice). In addition, Dunstan assisted in a collaborative research project with the National Metallurgical Laboratory in Jamshedpur, India that focused on applying calcium phosphate coatings to metallic glasses for use in artificial limbs.

During his undergraduate degree at the University of Oxford, Dunstan completed a research project that involved the use of cathodoluminescence to measure stress at high resolution in structural ceramics.

Dunstan has been granted limited recognition under 37 C.F.R. § 11.9(b) by the United States Patent and Trademark Office to practice in patent matters before the Office.
