Autrige did wonderful patent illustrations for both my provisional and non-provisional patent applications. The quality was excellent and he was very easy to work with, setting clear time and cost expectations. I highly recommend him and will use him again.

I consider Autrige to be a master of his craft. He created my patent illustrations in a clear and concise manner. And he had them back to me even faster than we had discussed. I would not hesitate to recommend Autrige to anyone needing illustrations.
