TMCH (Trademark Clearinghouse) is ICANN's centralized database for verified trademarks, designed to protect brand names during the launch of new generic top-level domains (gTLDs). It authenticates trademark data and connects rights holders with domain registries to prevent cybersquatting. For marketers, TMCH is a defensive strategy tool that secures digital real estate before public TLD launches and monitors for infringement during high-risk registration windows.
What is TMCH?
The Trademark Clearinghouse is not a trademark office. It is a validation and notification system established by ICANN in March 2013 [following recommendations from an international team of intellectual property experts] (Wikipedia). Rights holders must still register trademarks with their national or regional trademark offices; TMCH only verifies these existing registrations for use in the Domain Name System.
The system applies strictly to second-level domain names under new gTLDs. ICANN contracts Deloitte for trademark authentication and validation, while IBM (now Kyndryl) manages the technical database infrastructure [according to ICANN's provider selection announcement] (ICANN).
Why TMCH matters
-
Priority registration access. Trademark holders gain exclusive entry to Sunrise periods, securing matching domains before general public availability. New gTLD registries must offer this window for a minimum of 30 days [per ICANN requirements] (Wikipedia).
-
Real-time infringement alerts. The Trademark Claims Service notifies rights holders when someone attempts to register a domain matching their verified mark. Registries must maintain this service for at least 90 days after a TLD launches [according to TMCH FAQ documentation] (Wikipedia).
-
Defensive data validation. By March 2014, the system had delivered [over 500,000 Trademark Claims notices and prevented more than 475,000 trademarked names from being registered] (DomainIncite via Wikipedia), demonstrating its scale as a brand protection mechanism.
-
Rapid enforcement pathway. TMCH registration is a prerequisite for filing under the Uniform Rapid Suspension (URS) system, an expedited arbitration process that can suspend infringing domains within one week.
-
Ongoing surveillance. Rights holders can opt into free post-claims monitoring to receive alerts about exact-match registrations after the initial 90-day mandatory period expires.
How TMCH works
The process centers on two core services: Sunrise registration priority and Trademark Claims notifications.
-
Verification. Submit trademark documentation to TMCH. Deloitte validates the mark against official trademark office records.
-
SMD generation. Upon approval, receive a Signed Mark Data (SMD) file. This cryptographic token proves your TMCH status to registries.
-
Sunrise registration. Use the SMD during the Sunrise period (minimum 30 days before General Availability) to register exact-match domains across new TLDs.
-
Claims monitoring. During the mandatory 90-day Claims period, the system screens all registration attempts against the TMCH database. Potential registrants receive warning notices if their desired domain matches a stored trademark. If they proceed, the rights holder receives an alert.
-
Optional renewal. Maintain the record for 1, 3, or 5-year terms to preserve eligibility for future TLD launches and ongoing notifications.
Service tiers and pricing
TMCH offers two fee structures:
Basic. Designed for individual trademark holders registering small quantities. No bulk discounts available. Costs [$150 for one year, $435 for three years, or $725 for five years] (Wikipedia).
Advanced. For holders and agents managing large portfolios. Requires a prepayment account and operates on a loyalty point system. Registration volume and longer terms reduce per-mark costs.
Accredited agents like EuroDNS offer alternative pricing (e.g., €199/year) and bundle additional services such as proof-of-use management and centralized SMD storage.
Best practices
-
Pre-validate submission data. Incorrect rights details cause [over 50% of sunrise registrations to fail] (Ascio), forcing costly resubmission. Review trademark office registration numbers and classification data before uploading.
-
Monitor beyond the mandatory window. The standard Claims service expires after 90 days. Subscribe to extended monitoring services or registrar-specific solutions (like Ascio's Extended Service) to track registrations beyond the initial launch phase.
-
Configure multiple notification contacts. Relying on a single email address creates a single point of failure. Ensure alerts route to legal, marketing, and IT teams simultaneously.
-
Track proof-of-use deadlines. TMCH requires periodic validation that the trademark remains in commercial use. Set calendar reminders 30 days before renewal to avoid service interruption.
-
Combine with DPML for broader coverage. The Domain Protected Marks List (available through specific registries) blocks registrations containing your trademark as part of longer strings, not just exact matches.
Common mistakes
Mistake: Treating TMCH as a trademark registration substitute. Fix: TMCH only validates existing government-registered marks. File with your national trademark office first, then submit to TMCH.
Mistake: Submitting unclean data during initial registration. Fix: [Over half of Sunrise failures stem from incorrect rights details] (Ascio). Double-check trademark numbers, owner names, and jurisdictions against official certificates before submission.
Mistake: Missing the Sunrise window for high-value TLDs. Fix: Monitor the New gTLD Calendar closely. Sunrise periods open before General Availability and close permanently after 30 days minimum.
Mistake: Ignoring Claims notices. Fix: Act within the response window specified in the alert. Delayed responses may limit enforcement options under the URS or UDRP.
Mistake: Relying solely on exact-match blocking. Fix: Consider DPML services or extended monitoring to catch variations, plurals, and composites that TMCH exact-match rules miss.
Examples
Scenario: Product launch protection A beverage company plans to launch a new product line. Before the .drink TLD enters General Availability, the brand registers its trademark with TMCH. During the 30-day Sunrise period, the company uses its SMD file to register brandname.drink and productname.drink. When a competitor attempts to register similar domains during the subsequent 90-day Claims period, the brand receives immediate alerts and files URS complaints within days, achieving suspension before the competitor activates the sites.
Scenario: Portfolio monitoring A software company maintains TMCH records for its primary brand. Six months after a new .tech TLD launches (past the mandatory Claims period), the company's extended monitoring service detects a registration for brandname-support.tech. The early alert allows the legal team to send a cease-and-desist letter before the domain hosts phishing content.
TMCH vs URS
| Feature | TMCH | URS |
|---|---|---|
| Primary goal | Prevention and priority access | Rapid enforcement post-infringement |
| Timing | Before/during domain registration | After infringing registration occurs |
| Cost | $150-$725 per trademark (validation) | [$375 per complaint] (Wikipedia via URS Procedure) |
| Outcome | Registration rights and alerts | Domain suspension (not transfer) |
| Duration | Ongoing for term of registration | Decisions as fast as one week |
| Requirement | Must have verified TMCH record | Must have verified TMCH record |
Rule of thumb: Use TMCH for proactive defense during TLD launches. Use URS for reactive takedowns when clear-cut infringement occurs after registration.
FAQ
What exactly is TMCH? The Trademark Clearinghouse is a centralized verification database, not a trademark registry. It validates your existing government-registered trademark and provides tools (Sunrise access and Claims notices) to protect that mark across new gTLDs.
Do I still need to register with my country's trademark office? Yes. TMCH requires proof of registration from an official trademark office. It does not grant trademark rights; it only extends existing rights into the domain name system.
How long does the Sunrise period last? Each new gTLD must offer a Sunrise period of at least 30 days before domains become available to the general public. Some registries may extend this, but 30 days is the minimum [under ICANN rules] (Wikipedia).
What is the Claims period? This is a mandatory 90-day window following a TLD's General Availability launch. During this time, anyone attempting to register a domain matching a TMCH record receives a warning notice. If they proceed, the trademark holder is notified.
How much does TMCH cost? Basic pricing starts at [$150 for one year, with discounts for three-year ($435) and five-year ($725) terms] (Wikipedia). Accredited agents may charge different rates (e.g., €199/year).
Can TMCH block someone from registering a domain? No. TMCH cannot block registrations. It provides notifications and priority access. For blocking capabilities, look into DPML (Domain Protected Marks List) services offered by specific registries, which work in conjunction with TMCH records.
What is an SMD file? Signed Mark Data (SMD) is an encrypted file generated after TMCH validates your trademark. This file acts as your authentication key to participate in Sunrise registrations and proves your eligibility for URS complaints.
