I have to vent somewhere and possibly someone has some input that can help me.
Some years ago I invented a product that was ripped of by the person who was supposed to market it and his version is now sold world wide and I got nothing out of it except a bill from a patent lawyer that I could nor jump over. Patents are useless to the average person because it simply costs too much to protect them, a lesson learned the hard way.
Years pass and I am at the same point again, I can choose to market a new design or try and interest someone in either buying it or paying me a sum of money either for an outright buy or some sort of ongoing commercial agreement and either would suit me. To market it myself does not guarantee anyone copying it and a substantial amount of capital has to be invested but showing it to someone in the hope that they won't steal the idea is equally a problem.
The whole thing is a deterrent to leave good designs by ordinary people on the shelf, mine has been sitting in a cardboard box for about six years and that has stopped people who would welcome it from using it as it greatly simplifies a complex problem.
Has anyone had experience at this sort of thing because I have and it was not pleasant and has not resolved anything that could be applied the second time around. BTW it has nothing to do with woodwork or dust extraction.
