Sanjay Agrawal brings nearly three decades of legal experience to Marshall Gerstein's Electrical & Computer Technologies practice as Special Counsel. He oversees patent matters in the US and internationally, particularly within India, China, and Europe. Sanjay draws on his experience protecting the intellectual property of multinational companies. His experience as a counselor, IP strategist, and patent prosecutor has helped companies cut through the myriad of rules in various foreign jurisdictions to protect their innovative technology which is key to their business strategy.

Sanjay enjoys working with inventors and explaining the nuances of patent law. Whether the inventor is a serial inventor, part of a start-up, or a member of a sophisticated enterprise, Sanjay helps inventors determine what aspects of an invention can be patented, determines a patent filing strategy, and what future steps need to be taken to further business goals. For instance, Sanjay develops strategies to avoid infringement on issued patents, conducts competitive analysis to identify “white-space” opportunities to file patents, and works with marketing to identify jurisdictions to protect new products for the business.
