Our Patent Bolt blog began covering Samsung's patent applications for foldable devices/displays back in September 2011. We noted in a December 2012 report that it was becoming a trend in IP filings from Samsung, Microsoft, Sony and others. Months earlier we had noted that Samsung filed for a patent involving a tri-fold flexible/foldable display device. How real is this IP trend? Well, according to a new Korean report, Samsung is sticking their neck out on the line to announce that they'll deliver a foldable display device sometime in 2015. That's a two year window. So consider that to have been the starting gun sounding off to begin the race for the next generation of smartphone and tablet form factors.
