good luck (if it's already available as a product or the solution to the problem to be solved has been published, it can no longer be patented)
deep pockets (to file the patents, to defend them, to enforce them)

some things can't be patented, some things were patented a long time ago and the protection has run out, some things are on a product before any patent application was filed, and some things even get not patented to protect the knowledge on how they are working or are produced.
the patent watch dogs are trolls making their lives easy by assuming each technology on a product is actually patented. unless someone actually posts a link to a patent (all of them are available publicly, including applications pending) I won't worry.
(Source: I have a patent pending and spent weeks with a lawyer, researching if my invention was published, patented or sold before)

and I see you have understood how patents nowadays work (worst are uboat patents imnsho btw)
