“copy” pretty funny when you look at most of all ID is just re tweeking forms that sometimes encase new functions. All design work, all engineering work is all about using “stuff” that exists to come up with a “new” device. The reality, we all borrow and cross pollinate, the only real NEW stuff comes out of the r and d labs, generally with a zillion utility patents to protect them. Ink and now electrons are cheap, the only award worth winning is in the market place, if the OP is pissed somebody “stole his idea” well kid, ideas are like assholes, everybody has one and most stink. If you say " IT WAS A DESIGN" bfd, they are only slightly less common than ideas, everybody designs every day, its the definition of being human. If you built a prototype, ok that a lot more work and you will have thought more and learned more so it would sting a bit more but in the end so what. The road from concept to profitable product is LONG, and HARD, and winning (or not winning) a design challenge is step 5 of 6,991 (approx) that it takes to make a difference. Products are real, designs, well they just dreams generally gone with the light of dawn.
