About Stefan

Learn Stefan’s areas of practice.

As a former engineer and programmer turned lawyer, I help businesses of all sizes deal with intellectual property, technology, and business issues. We also provide general counsel services.

For more than a decade, I have represented clients in high stakes patent, trademark, trade secrets, and other litigations in federal courts throughout the country, and in New York state court. I also advise individuals and businesses on how to best protect their intellectual property and other proprietary information, and how to profit from them.  


Best regards,
