Trademark registration review time varies by country and region, and the specific review time will be affected by a variety of factors. The following is the time range for trademark registration review under normal circumstances:

1. Preliminary review time: After the trademark application is submitted, the Trademark Office will conduct a preliminary review to check the completeness and standardization of the application documents. The initial review time usually ranges from several months to six months.

2. Substantive examination time: If the trademark application passes the preliminary examination, a substantive examination will be conducted to evaluate the registrability of the trademark. The time for substantive examination will also vary depending on the country and region, usually ranging from a few months to a year.

3. Publicity period: If the trademark application passes the substantive examination, there will often be a publicity period to allow others to raise objections. The public notice period usually lasts from several months to half a year.

It should be noted that the above time is only a general estimate, and the actual review time may be extended or shortened due to various factors, such as the number of applications, review workload, review procedures, etc. In addition, trademark offices in different countries and regions may have different review efficiency and speed.

If you need an accurate trademark registration review time, it is recommended that you consult the local trademark office or relevant agencies to obtain the latest and specific information.
