About 30 years ago I had an Idea. I wear coveralls and work on heavy equipment. Knee pads killed me behind the knees. I took a new pair of coveralls and had my wife sew pockets on the knees with flaps secured with velcro. I put dense soft padding in the pockets. I filled out the form for one of those patent companies and sent it and my idea to them. A few weeks later I got a letter from their attorney. In it, he said the idea is to obvious and they wouldn't represent me. A few years later, carhart came out with something pretty close to my idea. I recommend legalzoom.com
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or your arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that you were our countrymen.
