Oh--that's a good point, bvanhiel. I wasn't arguing that the patent would be much use at all--simply that it could be obtained. A patent gained on such weak grounds as what I mentioned would be of little value to protect your IP.
But that's assuming you want to protect IP, as opposed to something else--like perhaps getting the foreboding "Patent Pending" stamped on something while launching it commercially. That's actually relatively valuable in itself sometimes--helps keep some of the competition at bay while developing your market. And if you only need that, go for an inexpensive design patent--super "weak" from an IP standpoint, but why pay more for ~2 years of "protection" under your pending status if that's all it's worth to you? (Yes, I've had clients who really only want a patent for this reason.)
So if you have an idea you think you could sell, you'll want to protect it as well as possible. Short of being able to do so, you do the next best thing--whatever that happens to be.
I'm not a patent attorney, nor will I ever be one. Personally, I'm coming to the conclusion that any patent you get from now on will be increasingly worth less and less--not because there's "nothing new under the sun", but because of our present litigious state. Any law can already be challenged. Any person can already be sued for any reason. Therefore any patent can be 1) challenged in court, or, 2) blatantly infringed upon, leaving you to pay lawyers to protect your idea. Unless you have the cash to do so, your patent is already, in effect, invalid. If your idea is worth anything, plan to face both of the above scenarios. I've found several of my patented products knocked off already (not that I hold the patent, but that I contributed to the claims while creating the design). See if it's really worth all this noise. It certainly isn't to me.
