Adopting the so-called "black box approach", which is to not file an application for a patent at all, is booming among domestic electronic business.
The approach is to hide the state-of-the-art technologies that they own not applying for patents for them, in the fear that their competitors could copy their latest technologies when published which could weaken their technology dominance.
"We are taking the "black box approach" to some parts of the core technologies that have been used for the development of super slim cathode-ray tube for digital TV," said Samsung SDI, who would rather get the world market with their matchless technology than take royalties.
It is the Japanese electronic business that originally came up with the idea of black box. Companies like Sharp Electronics and Matsushita Electric have found it natural, since early 2000, that they do not file applications for their primary technologies.
