Disclosure of Research Results Inherited from NTT
(Following restructuring of Nippon Telegraph and Telephone Corporation)

NTT Communications, which inherited various research results upon the restructuring of Nippon Telegraph and Telephone Corporation in 1999, discloses various technical information under the premise of fair compensation aimed at contributing to the growth and development of Japan's telecommunications industry. However, certain restrictions regarding these disclosures apply, as follows:

• Research related to user privacy and/or security protection may not be disclosed.
• The timing of disclosing technologies for the realization of specific services or products is determined on a case-by-case basis.

NTT Communications has four basic methods of disclosing inherited research results:

Granting joint-development manufacturers and other non-NTT Communications companies permission to sell hardware products based on inherited research results.

Licensing outside companies permission to use, duplicate, modify, sell, etc. inherited software.

Licensing outside companies to use inherited technical know-how.

Licensing outside companies to use inherited patents.
