i came up with an invention and have several drawings on it and how it works plus i made a prototype. the prototype was made with what my imagination could put together with a few things i got from menards and some welding. it works just not as good as what it could if i had more resources.
before i take it to a patent attorney should i get it notarized at my bank or is getting a few witnesses to sign and date it good enough. and should i have the attorney sign some kind of form to prevent him from possibly trying to use the idea for himself.
how trust worthy are some of these online patent sites like invent help or legalzoom? when i was in high school my gym teacher came up with an idea for some kind of exercise equipment and he turned it in to one of those online sites and he never herd back from them. he said a few years later he seen his idea on the market.
