This guide covers the procedure, required documents and costs. What is a trademark assignment? A trademark is an intangible asset that may be assigned to another party. An ordinary assignment of a Korean registered trademark takes effect through registration with the IP office, supported by the required application and documents. An agreement and payment alone do not complete an ordinary assignment of a Korean registered design right. The transfer must be registered with the IP office. Obtain an extract from the design register to confirm the current status of the right before proceeding. <Types of Assignment> Assignments may cover the whole right, all of a co-owner's share, part of the right or part of a co-owner's share. Consent requirements depend on the transaction.

Current status of applicable rights Check that the trademark remains in force and that renewal requirements have been met. The assignor should inform the assignee of the expiration date and renewal deadlines. The assignee should verify these details to avoid unintended loss of the right. Example of trademark registration (review of extinction registration) 3. Other encumbrances and issues Check for pending disputes and existing licenses before proceeding. Trademark Rights Transfer Procedures and Required Documents 1. Procedures Verify the assignor's right: ownership, legal status and maintenance-fee payments Review the agreement: assignment terms, price and required documents Prepare the assignment registration application and supporting certificates Submit the application form and pay the cost 2.
