Homayoon Rafatijo’s combination of scientific background, technical knowledge, and legal acumen allows him to identify protectable scope of a client’s intellectual property portfolio and represent them in their most complex intellectual property disputes.

Homayoon graduated with distinction from Sharif University of Technology – the leading institution for STEM fields in the Middle East – with a Bachelor of Science in Aerospace Engineering and a minor in Physical Chemistry. He relocated to the U.S. in 2013 to pursue a doctorate in Theoretical and Computational Chemistry from the University of Missouri.

After obtaining his first post-graduate degree, Homayoon continued to conduct research under a Multi-University Research Initiative grant funded by the U.S. Army Research Office, which competitively selects proposals based on their potential to improve the technological capabilities of the Army. During his tenure as a scientist, Homayoon also collaborated with world-renowned scientists, applied “Big Data” mining techniques, developed algorithms, designed simulations, and created computer codes to derive research conclusions. This culminated in several publications in prominent, peer-reviewed journals and ultimately sparked an interest in the field of patent law.

Homayoon maintained research and instructional duties while obtaining his Juris Doctor from the University of Missouri School of Law. During law school, Homayoon was elected as the President of University of Missouri’s Association of Intellectual Property and Entrepreneurship and also served as the Lead Article Editor for the Journal of Dispute Resolution. Several years of experience as a researcher, a referee for peer-reviewed, scientific journals, a college-level instructor, and a legal scholar have placed Homayoon in a unique position to engage with inventors, analyze cases for patentability and draft patent applications, and identify and litigate intellectual property infringements.
