You can read about it here, but essentially the claim is that a Morgan Lewis partner botched a patent application (negligently, apparently), and then intentionally tried to cover up the mistake. The plaintiff claims millions in damages.
i've been watching the growth in claims in this area, and recently saw data indicating that the number of claims in IP area remains constant but the severity -- the amount of damages -- remains high and is increasing. Every patent is worth more today, no doubt, than when I started practicing 20 years ago, but still... some patents are worthless or worth little, but it's interesting to see that trend continue.
