官方备注

Direct lithium extraction services use material transformation techniques such as adsorption, ion exchange, solvent extraction, and membrane processes to capture lithium ions. These services are classified in Class 40 because the Nice Class 40 Explanatory Note indicates that "transformation of an object or substance and any process involving a change in its essential properties" is included in Class 40. See also "Mining extraction" in Class 37.
