This was my first time applying for a patent, I am a service technician with some ideas and I am really lucky and grateful that I meet and used Donald's services to help educate and guide me through this complicated process to a very successful conclusion. Thanks again Donald, Jerry

Mr. Donald Ersler guided me through what I thought was going to be a very pain-staking process. Instead it was efficient, timely, educational and painless. From the beginning of the process to the end Mr. Ersler kept me constantly and instantaneously informed with every action taken. I was informed and educated by him every step of the way and was shocked at the speed in which he operates. Every time I had a question Mr. Ersler himself answered my call and did not hesitate to take the time to answer it. My experience working with Mr. Ersler was a refreshing and pleasant one and would recommend his services to anyone. If you are in need of a true professional, I would highly recommend that you stop here!

Mr Ersler has represented me since the beginning of 2014 to secure a utility patent through the USPTO. The Nonprovisional Patent Application was filed in February of 2014. The Notice of Allowance for the patent was provided from the USPTO in January of 2015. During his engagement Mr Ersler has prepared the application, responded to a restriction requirement, amended claims after a First Office Action, prepared and provided new independent claims, timely completed all necessary filings and secured the Notice of Allowance. He has, in a kind, steady and methodical fashion completed the necessary patent search, worked with the draftsman to secure all drawings, provided pgrgress reports, completed all filings and was always available to answer and discuss the project by phone. It should be noted that his charges are reasonable, he completes all necessary tasks on time, he is straight forward with you and works with you toward the achievement of your issuance goal. This is my first experience with Mr Ersler and I recommend his services without reservation. Please note that I am a practicing attorney for the last 37 years. You are welcome to contact me through Mr Ersler to answer any related questions. Yours very truly,
