"perhaps the trend is indicative of the behind-the-scenes actions related to the 336 et.al."
I was thinking the same thing. I would have to be totally convinced that I should pay now so I wouldn't pay more later. Especially in this economy - think about it - I wouldn't think companies would pay anyone anything unless they absolutely have to. They've got to be telling companies that the patents are close to a lock.
Part wishful thinking and part common sense.
Good luck to us!
