How to Become a Patent Millionaire

An anonymous reader writes "SF Gate has an article about people who patent ideas for things they have no intentions of building, hoping to license technology or block competitors from doing something similar. As if the patent system weren't screwed up enough already."

Lemelson and the bar code

[snarkh]

Lemelson had to wait years before collecting royalties for some of his ideas, such as the bar code.

Lemelson did not invent the bar code. In fact he engaged in practices very similar to the ones described in the article. His patent was an extremely generic one for machine vision applications, which according to his interpretation covered bar code readers. He was one of the people who never implemented any of their ideas, preferring to wait for other people to reinvent them and then ask for royalties.
