Sushil Iyer

Partner

Dr. Sushil Iyer (formerly Shrinivasan) focuses his practice on helping clients protect and strengthen their intellectual property portfolios. Drawing on extensive experience in both domestic and international patent preparation and prosecution, Sushil handles all aspects of patent law with a practical, business‑minded approach. His diverse technical range includes mechanical and chemical engineering—covering oil and gas drilling, completion, production, and processing—as well as mechanical systems and devices, including related medical technologies, consumer electronics, tablet support devices, and energy generation and conversion systems. He also works with software‑based innovations and emerging technologies.

While patent prosecution forms a core part of his practice, Sushil also helps clients leverage their innovations through strategic licensing guidance. He drafts and reviews a wide array of IP‑related agreements and conducts due diligence investigations that support complex transactions. Clients in applied sciences and those who need procurement services can also rely on him for patentability, validity, and freedom‑to‑operate opinions, as he regularly assists in developing long‑term patent strategies, including those involving reexamination proceedings.

Before entering patent practice, Sushil worked as a graduate research scientist, gaining hands‑on experience with technologies involving fluid mechanics, heat and mass transfer, microfluidics, nanotechnology, software, optics, electrical circuits, and imaging systems. This technical and legal experience allows Sushil to quickly understand highly sophisticated innovations and translate these into strong, defensible IP assets that align with the business goals of his clients.
