You can't own the angle of the turbine blades, or the layout of the hydrolic lines, or whatever the hell the specific issue is much more than you can own the canard wing.
Those are trade secrets or designs. It doesn't preclude someone from developing the same thing on his own, but if he breaks into your company and steals your designs, that is theft. The penalty for doing that is the same as if he broke into your company and stole computers or tools.
Let's say you, as a chef, spent one year writing a book of your recipes (and it was a lot of work to get the right prose, anecdotes, stories about the recipe and how you developed it, what other foods each recipe is good with, etc.), and your wife worked over that time taking artistic pictures of your prepared dishes for illustrations in the book. She experimented with different shots, lighting, colors, etc. Then, 2 weeks before you send the book to your publisher, you see a book on the market that is an exact copy of yours -- your recipes, your writing, your wife's photographs. Your publisher isn't interested in buying your book from you anymore. You find out that some guy broke into your study, stole an electronic copy of all your writing and wife's pictures, and published it as his own. He made $1 million, and is famous as a great chef who came up with amazing award-winning recipes. He gets his own fancy restaurant. His restaurant, that serves all these dishes and is promoted based on the popularity of the book, is the talk of the town and hugely popular.
You complain, but he says, "Well, you can't own writing or ingredients or the graphical appearance of food. I'm happy to see chefs steal from each other and compete -- it helps the consumer."
(His reasoning would in reality not help him in court, by the way. If you could prove he did steal it from you, you would likely win monetary damages, and the guy might do prison time for theft.)
