How come the images were taken off Google patents? Is this a bad sign?
Google just released an updated interface for their patent search. This is not the only patent currently affected by the glitch, so it is probably safe to assume it will be corrected in the coming days. It won't hurt to use the Send Feedback link at the bottom of their Patent Search page to increase their awareness of the problem.
In the meantime, the images are still available in the PDF and on several other sites, including the USPTO.
