Ayan Roy-Chowdhury, Ph.D., helps clients in the U.S. and around the world protect their inventions in electrical and computer engineering, computer science, software, mechanical engineering, and medical devices. Known for his depth of knowledge across a range of technologies, Ayan is the prosecutor clients often turn to for assistance with complex innovations.

Ayan has extensive experience in a range of technologies, including telecommunications and networking, artificial intelligence/machine learning, FinTech and blockchain, semiconductor devices, electronic circuits, network security and cryptography, autonomous vehicles, mobile device software/hardware, cloud computing technologies, and medical appliances, among others. As part of his practice, Ayan helps clients to obtain and expand their standard essential patent (SEP) portfolios in ETSI 3GPP, Wi-Fi, and video coding technologies.

Ayan’s practice also includes providing opinion and analysis work for clients looking to build their patent portfolios. Working closely with counsel in major jurisdictions around the globe, he applies his expansive knowledge of jurisdiction-specific regulations to effectively build and manage his clients’ international patent portfolios. In addition to patent prosecution, Ayan has experience in post-grant work before the Patent Trial and Appeal Board and he has supported litigation teams at Fish.

Ayan’s clients range from individual inventors and start-ups to multinational organizations and Fortune 100 companies. In each matter, Ayan tailors his approach to the unique business needs of the client, giving equal attention to each, regardless of size.

Ayan received his Ph.D. in electrical and computer engineering from the University of Maryland. Prior to his legal career, he worked first as a telecom software engineer in a large multinational and later as the principal engineer at a satellite networking start-up, experiences that gave him an insider’s understanding of the needs and concerns of organizations of diverse sizes in high-technology industries. Throughout his career, Ayan has authored technical publications, reviewed articles for several electrical and computer engineering journals, and served on the program committees of international technical conferences related to electrical and computer engineering and satellite technologies. He is also the inventor of two U.S. patents, one in network security and the other in cryptographic hash chains — technology related to the modern blockchain.

Ayan frequently serves as a mentor to professionals looking to establish themselves in the legal industry and speaks on panels discussing intellectual property law. In his free time, Ayan enjoys classical music, gardening, advocating for animals and the environment, and tinkering with gadgets.
