Don is a great attorney who’s well versed in patent and trademark law. He’s been an invaluable resource over the years and I’m happy to keep coming back for help with protecting new ideas and products.

I called around for 2nd opinion/consultation about a patent license and more specifically the company I'm doing business with or about to rather. Mr. Tiller answered my call himself, was a breath of fresh air with advice that made sense, never using negativity when personally referencing the company i asked his opinion on and infact assured me that the numbers they presented me were not inflated nor undercutting(unrealistic to secure contract)and that if it were him he would move forward with them on it. My hat goes off to him and his genuinely American business ethics for healthy advice with no mudslinging on the "other guys" of his profession. Very honest, very knowledgeable, very trustworthy.

Mr. Tiller provides excellent service. His honesty and guidance through the whole process from an idea to issued patent is indeed wholistic, professional, as well as far less expensive than dealing with a large firm. If you have an idea or need help/guidance in the IP arena do yourself a favor and visit with Mr. Tiller you won’t regret it.

Called asking for trademark and copyright services. Was very knowledgeable and detailed in the explanation and was able to use examples to help understand the process better.
