Client Testimonials

After having practiced law for almost 20 years myself, I understand and appreciate the technical expertise and customer service David offers to his clients on a daily basis. Thank you, David, for a job well done.

David Chinn (Huma, Inc.)

David has been excellent to work with. I really cannot say enough about how easy and enjoyable (yes, even trademarks) he makes the process. He's personable, easy to work with, super responsive (even after hours, when he shouldn't be), and always seems to be looking out for our company's best interest. He helps us to evaluate our needs, considering that we have divisions based in the US and Australia and trade internationally from each, so that we form the best strategy for where to file, from which division, and in which classes to most effectively protect our IP in a cost-effective manner. He keeps us on track and on time with filings and is always friendly in his communications, even when it take him several nudges to get the decisions he needs from us. Highly, highly recommend him!

Eileen Phethean (Kentucky Equine Research, Inc.)

David Nagle is a great lawyer -- very knowledgeable and responsive.

David Nagle is the best there is in intellectual property. This guy knows his stuff and gets it done quickly and more effectively than any lawyer I deal with. I cannot recommend him more strongly.
