Patently-O reports that Amazon’s 1-click patent has survived re-examination in the USA before the USPTO.
It would appear that the application was amended to tie the claims to use of a shopping cart:
The approved-of amendment adds the seeming trivial limitation that the one-click system operates as part of a “shopping cart model.” …. Because most retail eCommerce sites still use the shopping cart model, the added limitation appears to have no practical impact on the patent scope.
One of the (more intelligible) comments claimed that re-examination before the USPTO did not extend to consideration of obviousness issues.
