That's what the law states, in practice, ridiculous patents are granted as a matter of course.

And, in practice, most patent infringement lawsuits go down like this: "We own this patent and have a team of well-funded lawyers to defend it, we've assessed that you and your company are not financially capable of defending yourself and so we are willing to offer you a substantial licensing agreement as settlement. We suggest you take it."
