InterDigital (IDCC -21.3%) goes into freefall after DealReporter claims buyout offers for the 3G/4G patent holder, which put itself on sale in July, have been in the $1B-$2B range. InterDigital's market cap was north of $2.5B heading into today's trading, as hopes ran high of a sale price comparable to that for Nortel's patent portfolio.
