U.S. Patent Office re-examines Amazon's 'One Click' patent

U.S. Patent Office re-examines Amazon's 'One Click' patent:

"Actor Peter Calveley sought the reconsideration in documents filed in February, pointing out that a patent for similar technology was issued in March 1998, about 18 months before Amazon's. The Patent Office agreed last week that Calveley had raised a substantial question about the appropriateness of Amazon's patent, documents posted on its Web site show.

Calveley wrote on his blog that his crusade is revenge for an 'annoyingly slow' book delivery from Amazon. He used the blog to raise the $2,520 reexamination fee."
