"Steve was very helpful in explaining the process and types of patent protection I could apply for on my product. He assisted in developing the patent application in a very professional and timely fashion. All correspondence was handled professionally and he updated me regularly during the process. I have filed three patents with Steve and he was responsible and helpful during each process. I would recommend Greenfield Patent and Consulting to any young entrepreneur; it saved me a lot of time and money to work with a professional like Steve."

Steve Nelson, Expand Farm Products, Iron River MI

"I worked with Steve Greenfield to draft and file three patent applications for my inventions. All three applications were approved. Two of them issued and a third one will be issued soon. Steve conducted himself professionally and responded and addressed issues that came up in a timely manner. I would recommend his services to any inventor who might be interested in obtaining a patent."

Rick Waite, RM Waite Inc., Clintonville, WI

"I first went to Steven with very little knowledge about what to do next. I had an invention and a desire to protect it, but I also wanted to minimize my cost and risk before really knowing whether my plans were going to pan out. Steven introduced me to the provisional patent, took care of the application, and continued to support my efforts until the patent was finally awarded. I still bounce questions off him, and he is a valuable information source."

“Greenfield Patents and Consultation Inc. was an affordable solution in getting a patent for my invention. They were knowledgeable, honest and happy to spend as much time as needed to answer any questions I had. They also completed their work in a reasonable time. Due to my development of my invention only being a hobby of mine they worked around my schedule even calling me on a Sunday. I would recommend them to anyone.”
