Zordak writes "Amazon's infamous '1-click' patent has been in reexamination at the USPTO for almost four years. Patently-O now reports that 'the USPTO confirmed the patentability of original claims 6-10 and amended claims 1-5 and 11-26. The approved-of amendment adds the seeming trivial limitation that the one-click system operates as part of a 'shopping cart model.' Thus, to infringe the new version of the patent, an eCommerce retailer must use a shopping cart model (presumably non-1-click) alongside of the 1-click version. Because most retail eCommerce sites still use the shopping cart model, the added limitation appears to have no practical impact on the patent scope.'" Also covered at TechFlash.
