I was reading a news story about the patents US-Patent 5,838,906 and US-Patent 7,599,985. The patents are about:

Distributed hypermedia method and system for automatically invoking external application providing interaction and display of embedded objects within a hypermedia document

As I understand the patents, they are (among other things) about browser plug-in. If you follow the links  to the patents (either US-Patent 5,838,906 or US-Patent 7,599,985), you come to pages on the United States Patent and Trademark Office. At the top of the page there are a couple of red buttons, one of them is labeled “Images”. If you click on that button, you come to a page that requires an Apple QuickTime plug-in.

Apple of course is one of the companies being sued by Eolas Technologies for violating the patent.

I found this quite amusing.
