Presuming your question was serious and not rhetorical, then answer is "Yes you can."
The Apple vs Samsung is so ridiculous, that I want to submit some patents as well.- Is it possible for a EU citizen to submit patents in the USA?
Where and how to do that?
The web sites referenced above show you where.
The how is a bit more complicated.
In order to file the patent, you need to "reduce your idea to practice". That can be either actually building a prototypo or (as is more often the case) creating a fairly detailed description of your invention.
The description should be detailed enough that someone who is "skilled in the art" would be able to create a prototype of your invention simply by reading your description.
You also need to do some preliminary research to see if what you have invented has already been invented. That means doing a patent search (to see if anyone else has patented your idea already) or if someone has already published your idea without patenting it.
Once you create the detailed description (look over existing patents to get an idea of form), you need contact a qualified patent attorney to re-write your description using proper legal wording as well as write up your "claims". The claims (which are at the end of a patent) try to be a precise legal description of your invention.
It's not especially cheap-- I just went through this myself and cost about $10,000 USD for one patent in attorney's fees and filing fees.
You also need to figure out why you want a patent. Is it because you are building a business and the patent would give you protection of your (hopefully) original idea? In that case, it can be very worthwhile. Otherwise, think hard about whether its worth it or not.
