Panitch Schwarze Belisario & Nadel, LLP is an intellectual property boutique law firm that services clients internationally, with offices in Philadelphia and Wilmington, DE. We are driven by three core principles: a focus on IP law; a deep knowledge of the relevant scientific and technological areas we work in and the industries we serve; and providing “boutique” service that focuses on the needs and goals of each or our clients. We rely on these core principles to secure, monetize, defend, and enforce the most appropriate and effective IP rights for each of our clients. The team at Panitch Schwarze has deep technical knowledge, a solid grasp of the industries that we serve, and a true understanding of intellectual property issues and relevant laws.

We assist clients in developing IP monetization strategies and carrying out those strategies. We help clients navigate the IP of their competitors by providing practical advice and reliable legal opinions. We assist with numerous types of contested proceedings, both offensively and defensively, including IP litigations in various courts throughout the United States and contested proceedings before the U.S. Patent and Trademark Office (PTAB and TTAB), as well as coordinating with our foreign associates on contested proceedings abroad. Regardless of the IP needs a particular client has, each of our clients can be confident that the team at Panitch Schwarze has the necessary legal experience and the technical background to be a valuable asset to their business.
