| Foreign Filing? The researchers found a patent application, not a patent. The thing hasn't even been examined yet.
From public pair, if you look at the file history, you can see that Google initially filed a petition to keep the application from publishing. But later, they rescinded that petition.
So initially it looks like they didn't want anyone to know about the patent application, but then changed their mind since publication is a necessary precursor to filing one or more foreign patent application.
Possibly they want to have the ability to file in those countries in which all the major cell phone manufacturers are headquartered.
Maybe they do want to take over the world!
oops, just checked. They did file a PCT application.
Just as a side note, this patent application is related to an earlier application that was filed in 2004.
