As Apple (AAPL -1.2%) sold off again, the USPTO made a preliminary ruling to invalidate all 20 claims in an Apple multi-touch patent used in cases against Samsung and Motorola. Apple will doubtlessly appeal the ruling, which comes 6 weeks after the USPTO preliminarily invalidated Apple's "rubber-banding" patent. Meanwhile, the shipping date for the new 27" iMac, already stated by Apple to be supply-constrained, has been pushed out to January. The 21.5" iMac has a shipping time of 7-10 business days.
