Dr. Sushil Iyer (formerly Sushil Shrinivasan) is a Principal in the Dallas office of Fish & Richardson. His practice includes all aspects of patent law focusing on domestic and international patent preparation and prosecution in a broad range of technological areas including mechanical and chemical engineering (for example, oil and gas drilling, completion, production and processing), mechanical systems and devices (for example, medical devices, tablet computer support devices, energy generation and conversion systems), consumer electronics and software, to name a few. In addition, Dr. Iyer’s practice supports licensing, drafting and reviewing a variety of agreements, due diligence investigations, preparation of patent-related opinions, freedom-to-operate studies, client counseling and strategic prosecution, including reexamination work. He is also a member of the Firm’s internal training group for licensing and intellectual property agreements.

Dr. Iyer is also a member of the North Dallas IP Committee of the Dallas Bar Association and of the Patent Committee of the State Bar of Texas Intellectual Property Section. He works with these committees to organize CLE events on IP-related topics in North Dallas and other cities in Texas (for example, Houston, Austin) throughout the year.

Dr. Iyer is additionally a co-instructor of two courses offered by Patent Resources Group – the Patent Bar Review Course and the Patent Administration Course. As a co-instructor of the Patent Bar Review Course, he teaches several topics of patent law and patent practice to aspiring patent practitioners and in-house legal team members to assist them in passing the patent registration exam conducted by the United States Patent and Trademark Office (USPTO). As a co-instructor of the Patent Administration Course, he teaches patent paralegals and patent administrators of law firms and in-house IP legal teams on aspects of patent practice and administration to be followed to comply with the rules set forth by the USPTO.

Previously, Dr. Iyer was a Technology Specialist and then a student-associate at Fish & Richardson. Before joining the firm, he was a graduate research scientist at the University of Virginia and at the University of Maryland – Baltimore County where he obtained hands-on experience in technologies related to fluid mechanics, heat and mass transfer, microfluidic devices, nanotechnology, software, optics, biochemistry, electrical circuits, and imaging technologies.
