perfect answer
lawyers are the only ones that get ahead.
used to make mining/agricultural stuff.
we had a barrel of castings, auger pilot bits.
for one client, we ground the numbers off and used 6 pieces of carbide on each edge.
another client had the numbers removed but only had five pieces of carbide per edge, and the tip pieces were a different shape.
and finally, one person took them with the numbers, with hardfaced edges and one piece of carbide on the tips...
we had lots of castings like that...
some we just welded up certain holes and ground them flush...
nobody cared as long as they got what they wanted.
but lawyers are the only ones that make money if anyone did happen to care and start legal procedings.
we wouldnt make the parts, they wouldnt have the parts to sell, and finding someone else to do just their item specifically was not cost effective.
have you ever submitted an idea to one of those "development" companies?
the clause at the bottom says " 99% of clients dont make a profit, product doesnt reach market, this is a fee based service..."
they charge you for taking your idea, and letting someone else make the money from it.
its not like a century ago when any old blacksmith could patent a new engine and become famous for it...
