Trademarks in Guam

Competent Authority

• Name of Office: Department of Revenue and Taxation (DRT), Government of Guam
• Working Language: English
• System Type: Territorial jurisdiction within the United States. Local territorial filings coordinate closely with or build upon federal United States Patent and Trademark Office (USPTO) protections.

International Treaties

• Madrid Protocol & Paris Convention: The United States is a member federally; however, individual U.S. territories like Guam do not independently join international IP treaties or accept direct independent Madrid designations without operating under US federal frameworks.

Who Can Apply

• Applicants: Natural persons and legal entities using or intending to use a mark in commerce.
• Local Representative Requirement: No local representative is strictly mandated for filing basic local territorial paperwork, though compliance with US standards is heavily advised.
• Power of Attorney: Not formally required for standard filings.

Online Filing and Search

• Electronic Filing: Guam local filings are handled primarily via paper submissions or through the Department of Revenue and Taxation channels rather than a dedicated standalone online trademark portal.
• Search Database: Local trade name and business filing searches are managed via DRT, while comprehensive trademark clearance requires searching the federal USPTO database, as Guam local registration often serves as a recordal deposit of a federally approved mark.

Protectable Trademark Types

• Types: Word marks, service marks, and commercial identifiers used in trade.

Classification

• Classification System: Aligned with standard international classifications utilized under US commercial practices.
• Multi-Class Applications: Handled according to standard fee structures per classification class.

Examination

• Examination Scope: Reviewed locally for administrative compliance, business licensing context, and consistency with territorial records.

Publication and Opposition

• Opposition Procedures: Territorial registrations generally process through administrative review rather than a formalized pre-registration opposition gazette.

Timelines

• Registration Timeline: Processing times vary based on manual review workloads at the territorial Department of Revenue and Taxation offices in Barrigada.

Official Fees

• Specific territorial fee schedules for local mark deposits or trade name/fictitious name registrations (such as standard DRT filing fees) are governed by local Guam administrative regulations and must be verified directly with the DRT Business Licensing Branch.

Protection Term and Renewal

• Protection Term: Governed by local territorial statutes, frequently mirroring standard commercial renewal cycles or tied closely to the maintenance of underlying federal registrations.

Use Requirement

• Use Requirement: Commercial use within the territory or active federal registration standing is heavily emphasized.
• System Type: Guam territorial registration acts largely as a local recordal mechanism. True statutory priority and comprehensive enforcement across the territory heavily rely on federal United States Patent and Trademark Office (USPTO) protection.

Post-Registration Procedures

• Assignments and Changes: Corporate name changes, assignments, and structural amendments must be updated through the Guam Department of Revenue and Taxation to match business license records.

Legal Remedies

• Infringement & Litigation: Handled through the District Court of Guam or local territorial courts. Federal trademark laws (Lanham Act) apply fully to Guam, providing the primary statutory framework for federal infringement actions, counterfeit seizures, and nationwide priority.

Country-Specific Risks and Practical Notes

• A critical practical note for brand owners is that relying solely on a local Guam territorial filing or a DBA/fictitious name registration provides very limited legal recourse. To secure robust, enforceable brand protection, anti-counterfeiting advantages, and market security on the island, brand owners should secure a federal USPTO registration, which automatically extends its legal protections to the territory of Guam.
