About
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 of our clients.
Our Work
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.
Our Team
The team at Panitch Schwarze is composed entirely of IP practitioners with deep technical and legal knowledge and, as a result, our firm and our individual practitioners consistently receive accolades and top rankings by and among their peers. Our team of 20+ attorneys and agents have an average of over 20 years of practice in IP law, providing extensive experience in every facet of intellectual property law.
Firm History
