During the weekend of September 16th & 17th 2017 the TMCH will be executing a migration of the TMCH interfaces.
Consequently all operations via the agent-API and the secure web platform (https://secure.trademark-clearinghouse.com) will be down as of Saturday September 16th 7:30 AM UTC until no later than Sunday September 17th 15:00 PM UTC.
This migration will only impact the interfaces used to submit and manage trademark records and the associated services; this migration does NOT impact any TMDB operations (such as CNIS downloads).
TMCH agents working the API, will be contacted by their account manager with technical details regarding the impact of this migration.
For any issues, support or additional questions, please reach out to api (at) trademark-clearinghouse (dot) com.
