I knew nothing about them process I was engaging in. I had a couple of very unsatisfying experiences with patent searches. I had actually done better myself. I then went to Bay Area and they did a very satisfactory search. I decided to give them a try. I had some CAD drawings that I sent them and I seconded guessed myself a couple of times and changed the design a couple of times. They accommodated these changes and after a couple of rounds of prosecution I was notified that I was granted a design patent and that I as close to getting granted a second. I was thrilled. It was a major accomplishment for me. If I ever have another idea I won't hesitate to use them again. I highly recommend them Don J
