Dr. Cohen has been working as an Expert Witness in Software Intellectual Property litigation since 1997. This has involved patents, trade secrets, copyright (literal and non-literal), DMCA, business practices, contracts, civil and criminal matters. He has over 30 years experience in the software industry as an architect and engineer as well as a small group leader, both as an employee and as a consultant.

He has worked in areas as diverse as chip design and verification tools, optimum ship routing, ocean wave modelling for offshore oil exploration, bioinformatics, digital cartography, banking systems, DARPA funded research projects, and many others. His strengths are in algorithms, database and graphical user interface.

Much of this work has involved source code analysis.

He is a clear and fluent communicator, able to explain technical concepts and opinions to his peers, to attorneys and judges, and to a lay audience. He has testified both in Federal Court and before retired federal judges in arbitration hearings.
