The time required for substantive examination during trademark registration varies from country to country or region, and the specific examination time will vary depending on the work efficiency and application volume of each trademark registration office.

Generally, the substantive examination of a trademark may take anywhere from several months to a year. In some cases, substantive examination may be faster or slower, depending on the processing speed of the relevant trademark registry and the complexity of the application case.

It is worth noting that the substantive review in the trademark registration process is only one part of it. Before substantive examination, there will be other steps such as preliminary examination, trademark search and announcement. The time taken for these steps will also have an impact on the total length of the entire trademark registration process.

It is recommended that you consult the local trademark registration office or a professional trademark agency to obtain specific information about the substantive examination time. They can provide a more accurate estimate of review times based on your country or region.
