Even the text of some are pretty much as expected. It seems that they have a patent on single page applications (SPAs) to-a-T [1], elaborating that an application may use mechanisms like XHR and append an identifier to the fragment portion of the URL to keep history. Even if I subscribed to the idea that this was without prior art on the web in 2009, equivalent functionality already existed in desktop applications. To claim that it is a novel invention because it now works on a web page is disheartening. It's exactly this kind of behavior--claiming new ownership based on each abstraction--that leads to restrictions in some countries on patents which can only exist in software.
