His practice also encompasses drafting, reviewing and negotiating all types of agreements and advising clients on agreement-related issues. Examples of agreements on which he has worked include licenses for all types of intellectual property, software as a service agreements, privacy policies, terms and conditions for use of software, master sales agreements, and non-disclosure agreements, to name a few.
Dr. Iyer’s technical focus is on the mechanical, chemical engineering, computer-related and applied sciences arts. He has extensive experience in the following technologies: oil and gas drilling, completion, production, and processing; petrochemicals; medical devices; energy generation and conversion systems; computational fluid dynamics; self-driving vehicles; consumer electronics and accessories; and software. In the software arts, his technical focus has been in the areas of user interfaces and human-computer interaction, business intelligence, data analytics, operating systems, databases, e-commerce, client-side and server-side interactions, electronic document processing, and image/audio/video processing and management.
In addition, Dr. Iyer is a certified information privacy professional (CIPP/US) and a member of the International Association of Privacy Professionals. In this capacity, Dr. Iyer advises clients on the full range of privacy and data security laws and best practices.

Between 2016 and 2019, Dr. Iyer was a co-instructor of three courses offered by Patent Resources Group – the patent bar review course, the claims drafting workshop and the patent administration course. As a co-instructor of the patent bar review course, he taught several topics on patent law and patent practice to aspiring patent practitioners and in-house legal team members to assist them in passing the patent registration exam administered by the U.S. Patent and Trademark Office (USPTO). For the claims drafting workshop, he worked with junior or mid-level patent agents and associates to train them in all aspects of patent application preparation and prosecution, as well as client management. As a co-instructor of the patent administration course, he taught patent paralegals and patent administrators of law firms and in-house IP legal teams about the USPTO’s rules of patent practice and administration.
Before joining the firm, he was a graduate research scientist at the University of Virginia, where he obtained a doctorate in mechanical and aerospace engineering. Before that, he obtained a master’s in mechanical engineering from the University of Maryland—Baltimore County. Through his studies, 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.
