And if someone can prove that you've essentially reproduced unoriginal work with slight aesthetic changes which may or may not be unique, you don't have IP - which is one of the points I made earlier in the thread - you couldn't go after them selling the design. By your own admission, there is no copyright, trademark, or any other patent holding the idea(s) as your own, right?
I'll have to disagree with you here.
Consider Coke, Pepsi, and any other cola out there. There are definite differences in taste, however each of their products share many of the exact same ingredients. You could not keep the exact ingredients in the exact measure and keep the exact same production process, or else you'd be infringing on their rights, however, if you modify them even slightly, you have a unique product, and you can now claim intellectual property rules.
Of course, it's your right, and responsibility, as a business owner, IMO, to fight for your design. So much grey area.
This, I totally agree with. Grey areas abound! In North America, it's almost a sport to sue people, or even copy their idea and make money, and then use this money to fight the original product's owner. (I'm looking at YOU, Candy Crush Saga. Pre-Ninja Edit: I just read something about King buying the pre-cursor product to Candy Swipe, so this comment above may not be 100% accurate.)
I should have thanked you sooner Rick. Would you consider that if 5, any number of people for that matter, were trying to come up with an interesting shape of an arcade cabinet, all drawing from the same reference pool, where going to come up with something similar? I think the larger the sample size, the more likely.
True, and I'm certainly not saying that I'm going after anyone who's got a similar design - it would be impossible to do so, as I'd have to buy one of every cab that looked even remotely similar and do measurements and try and prove it.
I'm more talking about the three people who have already approached me for my cabs - outside of this forum, thankfully - with an eye on competing with me with my own designs. (I received word from a couple of CNC shops that I'm friendly with, that they were approached with a RFQ on mass producing bartop arcade cabinets - and then it 'magically' fell through because I couldn't produce them at the time. One of my friends at the shop was even able to get an admission out of one of them! Seems he was pretty pissed I wouldn't part with the plans when I couldn't sell him a cab, and outed himself. It was pretty surreal.)
That being said - you're right. People can - and will - copy great ideas until the cows come home, and I'm certainly not going to stop them from doing so.
