The Trademark Office under SAIC is responsible for endorsing and managing well-known trademarks.

A trademark registrant seeking protection for his well-known trademark should file an application with the Trademark Office. Upon endorsement, the Trademark Office will notify the applicant and publish the relevant information. For trademarks endorsed by the Trademark Office as well-known, no application for renewal of endorsement is necessary within three years after endorsement. 

If any person uses a trademark that is identical with or similar to the well-known trademark of another person on goods of a different class, insinuating that the goods are in some way associated with the registrant of the well-known trademark thereby causing possible damage to the registrant, the registrant of the well-known trademark may make a request, within two years from the date on which s/he obtains or should have obtained knowledge of such acts, to SAIC to stop such acts. 

Once a well-known trademark has been endorsed, SAIC will not approve the use of any word or device that is identical with or similar to the said well-known trademark by any person as part of the name of an enterprise which may mislead the public. For well-known trademarks that have been registered, the registrant may, within two years from the date on which s/he obtains or should have obtained knowledge of such acts, request SAIC to cancel it.
