While Sony (SNE -3.5%) promises to play nice with theater operators such as Regal Entertainment (RGC -1.7%) and Cinemark (CNK -1.9%) over who will pay RealD (RLD -1.3%) for 3D glasses for current releases, behind the scenes it works to develop glasses-free 3D technology. The company has a key patent that marks the first step (of many) to land what is called by some the Holy Grail of consumer tech companies - a viable 3D solution without the goofy glasses.
