With a diverse corporate, intellectual property and real estate practice, Ian has played a significant role in many high profile projects throughout the United States. Highlights among Ian’s background are major economic development and infrastructure development and finance projects, including public/private joint ventures, in conjunction with airports and mass transit facilities throughout the U.S. and extensive work regarding public private partnerships involving privatization of facilities on military bases. These projects often involved extensive coordination with federal, state and local governmental authorities including having the local laws changed to accommodate the projects. Several of these projects also involved the development of energy generation facilities, including green energy.

Ian acts as outside counsel to large and small technology and bio-tech companies (several of which specialize on agriculture, food security and food safety) coordinating their intellectual property assets with their business objectives and assisting with complex contract and intellectual property issues.

Ian also represents many not-for-profits (501-C3 and 501-C 6) including trade associations, foundations, schools and colleges acting as outside counsel providing wide ranging advice on diverse matters including technology issues, contracts, preparation of policies and staff guidance including social medial policy, acceptable use policy and proper utilization of cloud based services. Ian also regularly advises on board governance and board/staff issues, 501-C-3 compliance issues, and mergers and acquisitions of not-for-profits.

Ian also advises companies about the risks of cyber security, hacking, ransomware and the risks associated with data breach and data security. He has lectured on these subjects to many associations, schools and business entities. He has also worked with other professionals regarding school safety and preparedness.

In the energy arena, Mr. Portnoy counsels clients on energy efficiency, smart-grid, new battery technology demonstration, smart-house demonstration, photo-voltaic, low-flow turbine generation, energy savings performance contracts (ESPCs) and other alternative energy projects. He has worked on Public Private Partnerships all over the country. Ian assists federal, state, municipal and corporate clients to identify and address power purchase agreements (PPAs), energy tax credit issues and other similar issues. Further, he is currently assisting developer entities to develop “energy parks” on federal facilities.

Ian has published many articles and regularly speaks to professional and technology audiences. He was the senior editor of three major real estate publications and is presently working on several major real estate acquisitions.

Ian was a principal speaker at a conference in Japan for 350 Japanese CEO’s addressing the importance of effective communication for Japanese leaders in cross border transactions, including mergers and acquisitions and met with members of the Diet to explore these issues with Japanese government officials.
