David W C Chen

David has served me very well; our hard-fought claims were recently allowed. He has an excellent command of "what it takes" to write a powerful patent. He is a savvy and successful negotiator with patent examiners - he seems to have "a way" with them, especially during phone interactions. I am confi...dent you, too, will be well served if you choose his as your patent attorney.

David and his team have been amazing to work with. I have worked with them for the past few years...starting with a provisional patent for an idea, and then all of the steps to follow as we transitioned it to a full utility patent. David was so helpful and made it a point to teach me many things alon...g the way. As a young and first time business owner, I was able to learn a lot from the experience working with them. David always made sure I understood the steps that we were taking, and also worked with me to accomplish our goals while maintaining an affordable cost. Even as I ran into questions unrelated to my patent, David was always willing to help and answer my questions via a quick phone call or he would even follow up and send me informative emails to help me learn more about the legal processes involved in the startup world. I am so thrilled with not only the utility patent that he filed for me, but my overall experience working with and learning from David.

David is a brilliant attorney who has consistently produced exceptional results for CRISTA; always meeting or exceeding our goals. With David we have attained valuable trademark rights, defeated patent and trademark infringement claims/threats and obtained domains from others who improperly misused p...ortions of our marks. He is an expert at finding novel methods to accomplish positive results through the most expedient and economic approach. In short, he has proven to be a valuable asset to our organization over the past 9 years and has my highest recommendation

David Chen has been my company's patent attorney since 2006, when I first decided to file for a patent. He came highly recommended from a colleague. I did meet with other lawyers before selecting him. David explained each step of the process, his logic and strategy as he prepared the patent applicati...ons. Due to his excellent work, we have been awarded 2 patents with the majority of the original claims. This year, when our team identified new IP within the product design, I contacted David immediately for consultation. Recently he submitted patent application # 3 for us. Equally important to the quality of patent application and David's intellect, is his patience when explaining complex topics and law. His customer service is excellent, he has taken the time to get to know me, including my company's vision and values.
