Obtaining a patent in the US does not (inherently) provide you the right to make or use your invention.

 

Before you decide to go through the patent process in the US - spend large amounts of money, time and effort - please consider whether you will recoup your investments.  If you are going to start a company based on the invention, make sure you will be able to make and sell the invention (or provide the novel service).

Consider this: you invent a square, red beach ball.  It won't blow away as easily if dropped and it is easy to spot if dropped in the water.  Then suppose you obtain a US patent on the square, red beach ball.  You might not be able to make the invention because someone else owns a "broader" patent to just beach balls.  This other patent owner may be able to prevent you from making your own invention, even though your invention was novel enough to be granted a patent.

Clearly there are many issues to consider. The only point I am trying to make is - don't equate receiving a patent to having the right to make your invention
