Dr. Ishan Weerakoon combines deep technical knowledge and extensive industry experience with patent law to add value to his clients’ U.S. and foreign patent portfolios.
Nixon Vanderhye Shareholder Dr. Ishan Weerakoon brings in-depth understanding of computer and electronics disciplines to his practice. He prepares and prosecutes patent applications, provides patent validity and infringement opinions, performs intellectual property due diligence and patent portfolio evaluations, and assists in inter partes reviews and patent litigations.
Ishan, who holds a Ph.D. in computer science, held a number of engineering and research positions in the communications and networking industry at large corporations (IBM Networking Hardware Division, Hughes Network Systems, Lockheed Martin and General Dynamics Robotics Systems) as well as at a telecom network equipment/services startup before deciding to pursue a career in the law. This experience included work related to software-defined radio and satellite networking applications; network routing and application metering hardware and software for wireless networks; network and database systems; and consumer electronic devices for broadband services.
Ishan is the co-inventor on five U.S. patents in areas of telecommunications and computer networks, for work done during his time in the tech industry.
Ishan has authored or co-authored many articles on communication networks and network protocols that have been published in technical journals or presented at conferences. A former member of the Journal of High Speed Networks editorial board, he also taught college-level classes and led industry training on computer and telecommunications topics.
Before joining Nixon Vanderhye in 2013, Ishan spent about five years as an attorney at a prominent IP law firm in Washington, D.C.
