Intellectual Property Litigation and IP Corporate Transactions

Deepro has been lead trial counsel in dozens of cases, often taking them to trial and subsequent appeals. He is also experienced at managing inter partes review proceedings before the Patent Trial and Appeal Board. While he is often noted for his successes in Hatch-Waxman litigations, Deepro's litigation experience is far more expansive and covers matters related to product manufacturing, biotechnology, botanicals, business methods, web-related services and voice recognition software.

In addition to his substantial litigation experience, Deepro often provides patent-centric due diligence and other intellectual property counsel to multinational clients in connection with transactions such as public offerings and venture capital financings. He also advises companies on how to best leverage their IP portfolios in connection with spin outs and exit strategies. A recognized industry leader, Deepro had been named to the IAM 1000 leading world-wide patent practitioners list for eight years in a row and was designated an "IP Star" by Managing Intellectual Property for the second consecutive year in 2021.
