Any chance he meant "you are" or "you're" instead of "your" which is the possessive of the word "you" and not a contraction. If you are going to dispense legal advise you really should get the terminology correct.
Machinists should make parts. Leave it to the lawyers to handle legal matters.
I have thought about this subject and as a practical matter I came to the conclusion that there really is no way to protect yourself unless you are willing to spend more than $10,000 to obtain a patent in the first place and then untold sums to protect your rights under that patent if and when someone infringes on it. And even if you do put out those sums of money, you still may have an uphill fight if the invention is something of real value. From what I have been able to find out, that $10,000 figure is the bargain basement number in this world.
So you have to ask yourself two things: first is this widget really worth that kind of money? And secondly, do I have a way to come up with that kind of money to play this game? If the answer to either of those is no, then you are probably stuck with what I am stuck with. When I come up with an idea, I take pictures as I make it. Then I write a construction article and send it to George. About six to twelve months later I get a check for the article and several free copies of that month's magazine.
After that I figure it is pretty much public knowledge. BUT, I have a very good way of proving that I had thought of the idea before the date of that publication so if I do sell it, I don't think anyone can sue ME.
Frankly, I would take it as a complement if someone would start making whatever it was. I also have some of my articles on sale on another web site. I get a pittance for each sale. I am also working on making some YouTube videos to complement the above.
If you really do have a tremendous invention, GET A LAWYER. And then, with proper legal advise, try to sell that idea to a company that does have the money to get and defend the patent. Settle for a percentage instead of going broke trying to get it all. And even at that, don't be surprised if you get ripped off anyway. You will be in a long line of other inventors who have suffered that fate.

Any chance you meant "liable", rather than "libel?"
Mind.. some alleged designs...
