Google has been awarded a patent that describes a software method for selectively restricting the availability of content on the basis of access privileges and geographical location. On the surface, it may look like this patent covers techniques for censoring politically sensitive content in specific countries—a practice that Google has recently spoken out against in its ongoing feud with China. A closer look at the patent’s claims, however, shows that it has little to do with censorship and may actually relate to the company’s controversial book scanning initiative.
