From TheStandard.com: "During the past five months, dozens of intellectual property
sleuths have been trying to find enough evidence to debunk
one controversial patent: the patent that Amazon.com
(AMZN) has on the process of using just one mouse click to
place an online order.
The reward for finding such evidence? Ten thousand dollars
and the undying gratitude of Amazon's e-retailing competitors.
But every detective failed. While many came close, no one
qualified for the reward that had been offered by technology
guru Tim O'Reilly." Here's another story from the same site reporting on some of the reporting about the contest.
