Client Reviews
When I first started looking for a lawyer in the US, I had no idea what to expect. I represent an international online retailer from China and we were unfamiliar with the US legal system. An urgent legal message from the plaintiff regarding a trademark infringement case started my search for an experienced trademark lawyer. After calling and speaking to a wide variety of costly lawyers and law firms, I realized that Ted was one of the few personable, professional, and intelligent options that I came across during my search. Not only did he show me that he valued my time, but also my opinion and decisions regarding the case. If you are currently looking for an experienced trademark lawyer for your case, I strongly recommend you give Ted or his office a call and see what they can do for you. 老单
Ted is an outstanding Intellectual Property attorney that truly cares about his clients' needs. During one of the most stressful times of my life, Ted gave me the assurance and confidence that everything would be okay. His knowledge and expertise allowed us to find a swift and positive solution to my matter. As a lawyer myself, I can honestly say that Ted is a world-class attorney and I highly recommend him to anyone that has Intellectual Property needs. Blake Hall
I am a financial executive who has worked in the life sciences industry (pharma/biotech/med device) for over 15 years now. I have known Ted for over 20 years, during the course of which he has provided to me patent and other intellectual property-related advice. Ted has an extraordinary depth of patent law knowledge gained from many years of practicing at top tier corporate law firms. I find him to be incredibly thorough, thoughtful, practical and responsive and look forward to continuing to benefit from his capabilities and guidance in the future. Scott Kain
