This is one of those patents that we were pretty curious about, because the timeline of the story was quite interesting. Google announced Face Unlock as part of Ice Cream Sandwich last year. A little bit after that we found out that Apple had applied for a patent for what seemed to be the very same thing back in 2010. Of course, Google’s Face Unlock was based on technology from PittPatt, which had a patent granted in 2007. Google’s newly granted patent was submitted for approval in late 2011, just before the ICS announcement.
