Circuit City puts DIVX #patents up for sale, anyone in need of a failed disc format? -- Engadget

Circuit City's ill-fated video rental alternative, DIVX (not DivX), went belly up over a decade ago but just like Nortel, now that its parent company is belly-up its patents may still have some value. In case you've forgotten, the DIVX scheme offered discs similar to DVDs that were initially viewable for 48 hours, but could be activated for more time over a phone line. Now, the Circuit City Stores Inc. Liquidating Trust has entered into an agreement to sell the remaining patents to Imaging Transfer Co., but not before opening the sale to others in an auction, scheduled to take place August 16th.
