Sorry Troll, but without any legal proof to uphold your claim (trademarks, patents, ect.)... you're just wasting your own time & money on what would be considered a frivolous lawsuit, which is something that a judge would likely throw out.
Your idea is just that... an idea... Without anything concrete (like a designs or a working prototype), there's no merit to your claim as anybody, everybody & their grandmother could think up of a portable console that has similar power to an existing system. It's only when you start turning that concept into some more practical is when you start building your case .
Additionally, all the major console developers (Nintendo, Microsoft & Sony) don't rest on their accomplishments once a console launches. They start doing research & developing prototypes for their next console (or at the very least, create refinements for their current system), so they have plenty of paperwork & documentation on their side to counter such claims.
Therefore, proceed at your own peril.
