I agree. Patents are only useful in a court of law, and as a deterrent to prevent deep pocketed outsiders from stealing your idea (out of fear that they would lose any infringement lawsuits and therefore a lot of money). If your patent is crap, like the one that could feasibly be put on a prompt, then there is only the thinnest veneer of protection for your prompt idea, so it's pointless to make one if there is any value more than the 10-30 lawyer hours needed to take it to court and destroy it.
