Joshua Lorentz is Dinsmore’s Managing Partner and Chair of its Executive Committee and Board of Directors. Josh joined Dinsmore in 2001 and served in a variety of leadership roles including Chair of Dinsmore’s Intellectual Property Department and Finance Committee. In his role as Managing Partner, Josh is responsible for establishing and executing Dinsmore’s strategic priorities, including advancing business initiatives and promoting a culture of excellence, community and collegiality.

Josh helps companies in a variety of industries make intelligent decisions about their intellectual property rights and protect the ultimate value of their business — from IP audits/due diligence to IP litigation and licensing. He has tried IP litigation matters to decision, conducted claim construction (Markman) hearings, led and consulted in post grant proceedings and represented clients before the U.S. Court of Appeals for the Federal Circuit. He also has unique experience in licensing matters, negotiating hundreds of technology agreements for multiple clients, including dozens of Cooperative Research and Development Agreements with National Laboratories and Research Agreements with Universities.

Josh’s experience has led to exciting work, including being entrusted to handle a variety of matters for international clients, such as LexisNexis (a division of RELX Group). In fact, he has served as acting patent counsel for RELX Group, a global publisher and provider of workflow and business solutions. In his role as “in-house counsel,” Josh gathered a unique perspective of the challenges faced by multi-national corporations, which has solidified his practical approach to problem solving and enhanced the quality of service to clients.

Josh has been a driver behind the growth of the firm’s IP Department, which boasts more than 100 attorneys today. Through aggressive recruiting and focused mentoring, he has increased the number of attorneys through mergers and by bringing in partner and associate laterals from local, regional and national firms that strengthen the services offered by Dinsmore. Josh continues to be a strong proponent of building diverse teams, helping recruit and mentor the next generation of diverse Dinsmore attorneys and is a strong advocate for their professional development.

Aside from his leadership and legal practice, Josh enjoys competitive running, competing in local and regional running events each year.
