UPDATE: Looks like the USPTO is working on fixing the ability to have permanent links and bookmarks to individual patents.
Here is some interesting news… the United State Patent and Trademark Office has broken all of the static URLs of links to patents. In fact you can not even get a new static URL to link or bookmark to as each URL is now tied to browser session. Erik Heels has a post on this here and what you can do communicate with the USPTO.
