Review Jonathan Spadt

About Me

Intellectual Property lawyer with a business-centric practice.
I have experience in all aspects of IP protection and enforcement. Majority of work has emphasized domestic and international protection, strategic IP business management, opinion work, risk-avoidance, general IP planning and portfolio development, as well as licensing and transactions. Trial testimony on written opinions has led to successful outcomes.
Primary technology areas include medical devices, chemical processing, pharmaceuticals, polymers and polymer processing, and materials.
IP asset development for several clients has led to multi-million-dollar portfolios.
