If you're selling a physical product that you've invested hundreds of thousands of dollars into, then you can afford a lawyer.
Same for a software product, although they are much harder to copyright and protect.
If you've ever been involved in a civil legal dispute you know it takes months, even years for any action to happen (unless you're in the criminal courts, and even they move slowly).
I think you're worried about the wrong things, focus on getting to market and generating positive cash flow. If you're product is that easy to copy, it won't last long anyway.
