NTT conducts basic technologies R&D activities in three laboratory groups while also developing practical applications with its Group companies.
NTT has three laboratory groups: the Cyber Communications Laboratory Group, the Information Sharing Laboratory Group, and the Science and Core Technology Laboratory Group. These groups provide NTT with R&D muscle for the development of basic technologies that support the creation of safe, secure, and convenient ubiquitous broadband services and greater utilization of next generation networks. NTT's R&D results have steadily been put into practical use through the effective use of our "Comprehensive Commercialization Functions" and in close collaboration with the Group companies.
R&D overview

This point is about half-way down the page.
Protection of intellectual property
NTT protects the results of its R&D to maintain its competitive edge, but at the same time makes its intellectual property available to a wider audience by licensing technologies that would contribute to the development of industries and businesses as well as standardized technologies that are already used in society.
We also examine the third party rights of technologies used in our business to prevent infringement of third party intellectual property rights, and otherwise strive to comply with intellectual property-related laws and regulations and mitigate potential business risks by sharing information with our Group companies.
