Neifeld IP is a law firm specalizing in representing clients in matters in the United States Patent and Trademark Office, including ex parte and interpartes cases. We have participated or acted as lead counsel in dozens of inter partes matters, including patent interferences, IPRs, CBMs, and trademark oppositions and cancellations. Our main office is located near the main campus of the United States Patent and Trademark Office, in Alexandria, VA. However, our attorneys and staff are geographically distributed, working in our virtual machine environment. Our goal is to provide the small firm individualized legal service and loyalty that most people desire, coupled with a high level of professional legal and technical competence.
