What must a registrar do while processing Claims Registrations?

The specific technical obligations that registrars must satisfy when processing Claims Registrations is available at http://tools.ietf.org/html/draft-lozano-tmch-func-spec sections 5.3.4 and 5.3.5. In general, Registrars must verify domain name availability with the Registry Operator and obtain a CNIS lookup key if the label is covered by a trademark record, registrars must query the CNIS to obtain Claims Notice Information (see section 6.5 of http://tools.ietf.org/html/draft-lozano-tmch-func-spec section), use the Claims Notice Information to populate the Trademark Notice (see Exhibit A of http://newgtlds.icann.org/en/about/trademark-clearinghouse/rpm-requireme...), clearly and conspicuously display the Trademark Notice to the potential domain name registrant and inquire as to whether the potential domain name registrant wishes to continue with the registration. The Trademark Notice must be provided by the registrar at the time of potential registration in real time, without cost to the prospective domain name registrant, and must be in the form specified in the Trademark Notice Form (an example of which is attached to Exhibit B of the TMCH Requirements). The Trademark Notice must require an affirmative confirmation by the potential domain name registrant to continue with the registration.
