A wealth of experience
Although my team has done several design patent applications, I had several questions about how to handle a new use invention application. I asked Mark if I could schedule an hour to consult with him. Instead of that he called and answered all of the questions I had at no charge! He was really insightful about the process and knew so many important nuances we will definitely work with him on the full patent application.

I am a 1st time user of the Tom Martino referral list - VERY SATISFIED! Mark Trenner was very helpful, HONEST, knowledgeable. I did not know where to turn in regards to patents/trademarks, so I asked Tom Martino's crew. I would definitely recommend the Trenner Law Firm - Mark was extremely helpful, honest and ready to answer any and all of my questions. Thank you Mark! I appreciate all of your help! 7/19/12

I trust him completely. I'm thankful I hired Attorney Mark Trenner.

He explained the patent process in a comprehensible way. Mr. Trenner's experience wand expertise was also evident as he processed the paperwork that I had given him regarding my provisional patent. He explained what was lacking and offered to provide a better model for my invention. The final product explains my invention to a tee. I was very impressed with the detail involved in the explanations and sketches involved. I would also like to commend Mr. Trenner for patience with and inventor who made changes to the invention description and drawings as we went through the process. Mr. Trenner is professional in manner, and extremely knowledgeable in the legalities of the patent process. I highly recommend him.
